Emily UR: A Rainy Day in the Field is better than a Sunny Day in the Office

The NOAA Hi-Def Radar app

As previously discussed, my IRP will be focusing on the concentration of nutrients in stormwater runoff into stormwater management ponds in two different environments. After reading some previously conducted research about atmospheric deposition and stormwater runoff I've decided to take a similar 'before and after' approach to measuring the concentrations of nutrients, before and after a rain event. First and foremost, I'm going to need additional information from those who lay down the fertilizers from each location. The Halifax Plantation homeowners association should have this information for their golf course care and I can personally ask the people who live in the surrounding houses how much, if any, fertilizers they use and and how often. For the Tuscawilla Park location, I will have to contact the City of Daytona Beach who care for all the landscaping of the park and ask about their fertilizer application, if any, and how often.
It's important to note that Tuscawilla Park was once a marsh wetland that was drained to become a public park. When speaking with the City of Daytona Beach, I plan to ask them how long ago the conversion from park to wetland occurred and for what reason, if any.
My scientific question is, "After a rain event, which retention pond is more heavily polluted by nutrients?" & "Is the pollution of nutrients due to stormwater runoff of atmospheric deposition?"
The quickest route between the two ponds takes approximately 30 minutes and is approximately 24.5 miles (google maps) so I'm not certain that I'll be able to collect rainwater from the same storm over the two areas on the same day as I would like to but regardless, my materials and methods are as follows:
Materials

• 4 2-Gallon Pails w/ handle from the Home Depot (Model #2GL WHITE PAIL)
• Hach DR/890 Colorimeter (Method 8048 for Phosphate & Method 10021 for Nitrogen)
• VWR Clinical 20 Centrifuge 
• Fisher Scientific MaximaDry filter pump
• 500ml Bottles for Water Samples
• NOAA Hi-Def Radar app for iPhone 
• NOAA HYSPLIT computer model

Methods 

1. Collect two samples of water from each pond before a storm. Each sample will be brought into the lab immediately for analysis.
2. Tracking a storm using the NOAA Hi-Def Radar app for iPhone, I will place two buckets around each pond during a storm to collect the rainwater associated with the later runoff. The water from each location will be properly stored and brought into the lab as soon as possible for analysis.
3. Once the storm has passed, I will take two samples from each location to compare the concentrations of nutrients from before to after the storm. 

An example of a NOAA HYSPLIT model

The methods extend far beyond "to the lab for analysis" but as far as testing for nitrogen is concerned, I am inexperienced. What's important is that the water collected will all be testing for total phosphate and total nitrogen present and my chemical spreadsheet can help me determine sources of pollution. Using NOAA's HYSPLIT (Hybrid Single Particle Lagrangian Integrated Trajectory), a computer model used to compute air parcel trajectories and dispersion or deposition of atmospheric pollutants,
I should be able to determine what kind of aerosols are present in the atmosphere during the rain event which will help to give a source of pollution for each location.
 

Deanna, UR- Gone Fishing

Since my IRP is dealing with red drum, and the population of legal size fish in the Flagler County area I will basically be catching fish, taking my measurements and safely releasing them.



Drawing of a popular red drum fishing
method (which I will be using).

Based on my research from my previous blog posts, I will be focusing on inland salt-water waterways, since this is where red drum remain for the first few years of their lives (reaching the legal size of 18 to 27 inch in these years). If weather and schedule permits, I would like to fish at least three completely different areas and a few times in each spot based on number of fish I catch each time, probably starting at the Princess Place Preserve here in Flagler County (which leads into the intercostal). I also plan on fishing from a kayak, instead of on land - allowing for a better chance to catch more since a lot of local fishing spots have pretty much been overfished. My step father will be assisting me because handling a 14 foot kayak by myself would be a bit difficult and it will help me to have a better chance of catching more fish.


Aerial photo of part of Princess Place Preserve

I have chosen to use rod-and-reel method simply because places, such as the Princess Place Preserve, are full of oyster beds therefore, using any type of net would be difficult. And of course fishing licenses are required. As far as specific hook sizes, weights, line types/strength, and bait, I have not completely settled on any of those decisions because using just one "set up" (so to speak) could work one day or in one spot but maybe not in another. However, most likely I will be using live shrimp and popping cork (shown below) for starters.


Example of a "popping cork". The beads on each end
make noise which attracts fish.

After catching a fish I will identify the fish (since I am specifically after red drum). Red drum are easy to identify simply because they commonly have a copper-bronze color, large scales, and usually have one of more eye-spots by their caudal fin. Then I will take the GPS location of where the fish was caught and a length measurement. The reason for using the length of the fish for my data is because the length is what the law is based on. After gathering my data the fish will be released- maybe with the exception of one or two legal size fish since I have heard and read many things about how good red drum is to eat, of course only for science. 


Victoria Czupta UR- "I'd Rather be Fishing"

     Throughout the ages, many people have been terrified of sharks of all kind. No matter the species, size, or location people have always been had the kill or be killed attitude with these predators. Sadly, this also includes the humble and extremely safe whale shark, that only eats small fish and krill, just like the blue whale. Because of this view we humans have of sharks, I find I enjoy studying them and enlightening people to how they really are.

Mustad hooks of different sizes. These ones are J hooks,
because they are shaped like the letter J.

    While researching for my project, and based on what I did in the passed, I found that there are lot of different ways to catch any type of shark. The most common way is just a regular fishing pole with a hook and bait. Since there are a lot of local fishers, many people will catch fish, as well as sharks, just by regular day to day fishing. In some instances, like tournaments set specifically for sharks, there are particular types of gear. Some of those include: PowerPro 80-pound test braided onto a reel (pound test indicates the maximum pound tension at which the line should/may break, although it does not indicate the maximum weight of a fish that can be caught (#1)), light weight, heavy duty rods like "Shimano Terez TZCX66XXH rods", a belt and harness to latch the rod into allowing more control of reeling in the catch instead of fighting to hold the rod while reeling in, and Mustad 7699d hooks which come in a variety of sizes depending on what the catch is (hooks can either be J hooks or circle hooks also depending on the target catch). (#2)
With this information, it is determined that finding the proper hooks and line will help catch some of the larger sharks that may be caught throughout this experiment.

     After finding that we will be fishing from piers and off the beach at a few different locations, yet to be established for specifics but definitely including the Inlet on both the Daytona and New Smyrna sides, and using King Mackerel (or very similar) as our bait, we can catch a decent variety of species and sizes of sharks. We will tag smaller sharks with small barbed tags such as the one pictured here:

Small shark tags that eventually fall off due to age,
heavy swimming, or other environmental factors.

     Larger sharks will get heavier duty tags that require more effort to attach almost like the tags that are seen on livestock, like a permanent earring but in the case of a shark, is attached to the dorsal fin (I am uncertain as to the tags that I will receive yet, but it is being worked on).

Anatomic Structure of a shark including the precaudal notch, or pit,
and at the pelvic fin showing claspers for a male,
which a female does not have.

     As of the methods, there are student volunteers that would like to help in the catching process. On certain given days, we will determine the location at which the fishing will start. Recording the Latitude and Longitude of every location as well as environmental factors that might help determine future locations such as air temperature, water temperature, tides coming in or going out, rain, cloud coverage, and possibly salinity and dissolved oxygen (which is highly important because too low dissolved oxygen means that the sharks will not be able to "breathe" properly in that water). Once a specimen is caught the weight, precaudal notch length (before the tail fin, there is a little notch), fork length (the area where the tail fin splits and is at its shortest point from the nose), and total length (from the nose to the tip of the top half of the tail as is would be when relaxed in the water), gender, and species will all be recorded. From there, the tag number will be recorded with all of this data so when attached to the shark, the tag will be its "name". From there, the specimens will be carefully released back into the water. Afterwards, we wait and find out if anyone catches that shark and relays the information that is placed on the tag, which gives us how long after tagging it has been, where it was caught, and its same measurements after the initial tagging has happened.

Just typed in Daytona Beach Shark Fishing and this came up.
Showing how big some local sharks can really get.

Chris Browne, UR - Insane in the Membrane

     

     Coliforms are classified as. E. coli is a fecal bacteria that is found naturally in the environment, but more specifically around waste water, sewage, and places where people live. My paper will research how bacteria can affect the surrounding marine and waterway environments. My research will include water samples from Canal Street, new Smyrna beach.

Bacteria is everywhere.

    

    I’ll be using the USEPA Membrane Filtration Method, 8074 with help from the Science department head, Dr. Horikomi. To paraphrase the process of research, I’ll break it down into three pieces, the filtration, Incubation, and examination. Filtration will start with using an autoclave to completely sterilize the funnel and filter assembly. Equipment used will be a membrane filter, funnel, manifold, Incubator, forceps’, BGB Broth, Agar plates, and filter set up with a 0.45 micron pore size to catch the desired bacteria. A prepped sample will be run through the filter. A vacuum will be used, for the filtration process.

Filter Assembly

     

     I will incubate the cultures on a Petri dish, making sure there is no air where the filter meets the cultures broth (food source), for 24 hours. Followed by a microscope examination, counting the stained blue colonies of bacteria in the given dish. Recording results, I’ll make an interpretive statement of findings, based on the accepted forms of datum reporting. I believe by using this filtration process I will be able to identify and count how numerous bacteria is in the canal street waterway, and summarize from other research the sources, and how bacteria can be reduced, as to respect our marine environments.

Rachel UR-- Skates vs Rays, The Identity Crisis of the Sea

           Hello fellow bloggers! In this weeks blog I bring to you one of the biggest mysteries of the sea, what's the difference between a skate and a ray? First, let's take a look at one of the most common ray seen off the coast of Florida, Dasyatis Sabrina, more commonly known as the Atlantic Stingray.

Dasyatis Sabrina, commonly known as the Atlantic Stingray

   The Atlantic Stingray is normally found in coastal waters including but not limited to estuaries, lagoons, and sometimes rivers. They feed off of benthic (occurring at the bottom of a body of water) organisms such as small crustaceans and shrimp. Occasionally they will feed on small fish that swim near the bottom. Rays generally are a non-aggressive, but they do have a barb near the base of the tall that they use for self-defense. Rays also give birth to live young. The Atlantic Stingray normally has about one to for pups per pregnancy. The Atlantic Stingray is shaped like a pancake. They have a slightly pointed nose with the fronts of the wings rounded, which can reach up to 2 feet in diameter.                                                                                                        

Raja Eglanteria, commonly known as the Clearnose Skate

   The Clearnose Skate on the other hand is shaped like a spade.  The front part of the wings come in at an angle and can reach a diameter of 2.5 feet. They are most commonly found in coastal waters but can live at depths of up to 1,000 feet. These skates also feed on benthic creatures including small squids and fishes. Clearnose skates do come into estuaries and bays to reproduce. Unlike the Atlantic Stingray, skates use small leathery like egg sacks to protect their young. These egg sacks can wash up on the beaches and are often called mermaid purses. These purses can reach lengths of 9 cm and widths of 5.7 cm. A single female clearnose skate can lay as many as 66 eggs sacks in a single reproductive season. They also lack the barb that stingrays have. In the barbs place is a row of spiny scales along the back of the ray.

Clearnose Skate egg case often called a mermaid purse

     My plan for my IRP is to find these eggs cases as they wash up on the beaches and take measurements from year to year. By doing this I can monitor the eggs for any changes or any egg cases that might indicate an invasive species.

Renee; UR: Welcome to the 21st century kids!!

I may not be able to get my mitts on a flying car yet (darn you Back to the Future for lying to me!) but there are a lot of awesome bits of tech to make life as an undergraduate researcher easier! For examples lets consult some highlights from my materials list thus far:

BLU is headquartered in sunny Miami FL
and has proven to be a leader in affordable
no contract smartphones.

1) My shiny new Studio X cell phone from BLU (Bold Like Us) 

 This baby has some impressive specs (the details of which you nerds out there can check out at your leisure via the website linked above) considering it isn't carrier specific and cost me less than a smooth Benjamin ($100). 

For my IRP I will be using the GPS locator services to tag my sample locations for mapping purposes and future reference, taking picture with the 8 megapixel camera (a megapixel refers to the image size when a digital picture is taken) for documentation purposes and most fun of all the latest Collector App from ESRI will help me with data collection in the field and make future GIS analysis easier.

You may remember I mentioned this app previously in my introductory post and I am looking forward to becoming more familiar with it and all of its functions during this study.

Ohaus- starter water
analysis pen meter

2) Precision Beyond Balance ST Series Pen Meter by Ohaus which I will be using to measure redox reactions (an oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species) these reactions involve gaining or loosing electrons and it is this electron change which the device measures from my understanding. I'm still figuring this fancy redox thing out so if anyone has some helpful links please leave a comment and share the wealth of knowledge.

The rest of my materials list is less exciting but no less important as you can see below.

Materials

• Measuring tape
• 10, approximately 1-cup containers
• clean trowel
• plastic flags
• cloth for cleaning trowel between samples
• 2mm mesh slieve (per Ag Extension processing requirements)
• 10, wax free, 2.5x3 inch bottomed paper bags (per Ag Extension processing requirements)
• Sharpee Marker
• Soil Test UF Ag Extension paperwork

My process still has a few kinks to work out...

My biggest problem right now is going to be finding a place to air dry my soil samples as is required for the Ag Extension to test the samples and sifting the soil to meet the Ag Extensions testing requirements. I'm sure once I give Dr. Emmett and Dr. Woodall a poke we will be able to work it out. The sifting I'm not so confident about...

Next I need to fill out the first wave of Ag Extension paperwork and find out when they will accept my samples.

The next part is fairly easy: go into the field and take the samples!

Procedure: Root Zone Samples

1. determine reference pitcher plant specimen
2. document GPS location of sample and corresponding reference specimen with Collector App*
3. measure distance of no more than 6in from base of pitcher plant specimen's vegetation and mark with flag.
4. document the aforementioned distance
5. use trowel to collect approximately 1-cup of dirt making sure to stay within the top 5in of soil.
6. close sample container tightly and label container with specimen number and date. This data will also be added to Collector App*
7. thoroughly clean trowel
8. take redox measurement and enter in Collector App*

Procedure: Distance Samples (I'm still working on this title)

1. determine a reference pitcher plant specimen
2. measure a distance of at least 3 feet along ecotone (an ecotone is the transitional area between two major ecosystems, see the picture below for a good illustration of an ecotone; for my study the ecotone's exact location is not yet defined) from the reference specimen

   

   Here is a nice diagram I found on the Google to help explain
   where the ecotone  is.

3. document GPS location of sample, corresponding reference specimen and distance from reference specimen with Collector App*
4. use trowel to collect approximately 1-cup of soil, being sure to stay within the top 5in of soil
5. close sample container tightly and label container with specimen number and date. This data will also be added to Collector App*
6. thoroughly clean trowel
7. take redox measurement and enter in Collector App*

* Note: as this is a 'field test' of the Collector and relying purely on tech can end in disaster even in the 21st century any data recorded during my study will also be taken in good ole hard copy format in the lovely field journal we all have come to know and love. :)

Procedure: Post Sample Collection (a work in progress)

1. spread out samples in individual, contained and labeled areas to air dry
2. for each sample label a wax free, 2.5x3 inch bottomed paper bag (per Ag Extension processing requirements)
3. prepare any necessary shipping paperwork and container to ship samples in
4. once the samples are dry sift each sample individually using a 2mm mesh sieve
5. (I need to consult Dr. Emmett on what we should do if none of the samples will filter through such a small gauge sieve... o.0... Any process we may have to add would go here)
6. place samples in their corresponding, pre-labeled paper bags
7. pack bagged sample in order for shipping to UF Ag Extension
8. (I need to consult Dr. Woodall on if my samples will be shipped from Daytona State College or if I will be making a trip to the post office. My money (and hope) is that shipping will be from the college)

Just for fun: Dr. Woodall trying to explain to me how to
use the Hach DR/890 Colorimeter which measures turbidity
while I took 'photo-documentation' of our field
excursion last Friday.

Q&A

Q: Deb n' Paul (Dr. Woodall)

Ok so here is your correction. When citing an e.g., article within your 'article' it should be e.g., Wheeler, E., et al., 2010. the et al lets the reader know there are other authors and you should always include the date since Mr. Wheeler likely had publications from other dates. Also--thanks for giving those great definitions of terms I'm unfamiliar with! It really helps!

A: Yay!!! You do love me after all! lol

but seriously, thank you for the et al and date tip. I went and made a big note on my apa citation guide about it. Citation is my Achilles heel here and I need all of the help I can get.

I'm glad you appreciate the definitions. I get so used to using big technical words that I don't realize I've lost people most of the time. The exception being my mother cause she interrupts me mid-sentence to inform me she left her dictionary at home. She isn't very happy when I remind her Google is just a few taps away on her fancy shmancy Iphone. ;)

Samantha, CUR- $3.6 million Park.

          First of all I would like to say kudos to the St. Johns River Water Management, Department of Environmental Protection Department of Transportation as well as Brevard County for funding and managing this project. As we all know the Indian River lagoon is a imperative and biodiverse estuary in Florida associating specifically with my hometown, New Smyrna Beach.  Although expansive in range(156 miles) and covering about 40% of the Atlantic Coast of Florida, the estuary has not fared well in the midst of the ever-increasing human population and associated activities that have been detrimentally effecting the environment.  As of 2015 citrus fields gave way to a park of ponds to capture fertilizer-laden runoff from Barefoot Bay and surrounding areas that one ended up in the Indian River Lagoon.

A map highlighting the features of the Wheeler Stormwater Project in Southern
Brevard County 

 The new Wheeler Stormwater will catch pollutants from a 21,000-acre watershed before they can reach the North prong of the St. Sebastian River which feeds into the IRL.  The project was completed in May 2015 and other opportunities such as walking trails and kiosks will be completed by the end of 2016 and open to the public in approximately one year.  The series of ponds will keep a yearly average of 16,753 pounds of Phosphorus and 27,223 pound of Nitrogen from entering the lagoon, according to the district. Each pound of those nutrients have a potential to grow 500 pounds of algae!

Work continues on the Wheeler Stormwater Park Project, a 300-acre facility designed to capture pollutants in stormwater such as nitrogen and phosphorus. Collected stormwater will be filtered through a series of interconnected ponds that will capture the majority of pollutants before the water is returned through the Sottile Canal to the St. Sebastian River. The four-year project is scheduled to be completed by the end of the year. (ERIC HASERT/TREASURE COAST NEWSPAPERS)

"The more of these we do the more of Phosphorus and Nitrogen we take out of the system, but don't expect the lagoon to bounce back overnight," said Duanna Defresse, director of the Indian River Lagoon National Estuary Program.

Dave, UR - Understanding sound propagation

People are critical of sound effects in sci-fi films, because sound isn't propagated through a vacuum. After all, there is no atmosphere to conduct sound waves forward from their source. Many people take the transference of sound waves through our own atmosphere for granted, and even more people assume that sound travels through water the same way it travels through air. This is not only false, but sound actually gets conducted through water better than it does through air--farther and faster.

In the same way we breathe air and not water, this begins by understanding that water is more dense than air.  As the image on the right reflects, water density helps capture energy and transmit it much better than air, because the molecules are more tightly packed.

This is the point at which we believe that we should be able to capture much more specific signals from underwater organisms, than we could above the surface.

To that end, and in order to refrain from wasting time and materials, I am currently researching much more specific information on both the transmission of sound energy through water, as well as what attempts have been made to do so, from an engineering perspective. If you would like to follow along, I have cited the sources I am presently reading in order to refine our design idea. I have been reading largely about how sound moves through water, and what approaches have been taken towards acoustic collection, but the bottom resource also discusses how dolphins collect, and since they are our target organism, I'd prefer not to ignore nature's approach either.

Emily UR - Stormwater Runoff and Atmospheric Deposition Studies

Quick review: My IRP is focusing on the nutrient pollution originating from stormwater runoff of two different stormwater management ponds (SMPs), one located in a very urban setting & the other located in a county park. During my library research, I found my topic of interest to be a rather uncommon study but was determined enough to find two well-executed studies addressing a similar issue. The first study, titled "Storm Water Quality of First Flush Urban Runoff in relation to different Traffic Characteristics" was definitely the most helpful because it studies various sorts of stormwater runoff pollution in varying traffic conditions which allowed the Swedish researchers to make a positive correlation between high traffic volume and excess pollutants found in stormwater runoff samples.¹ This study, along with the information learned these past two weeks about rainwater (via the Chapter 3 slides in Aquatic Environmental Science) have given me a wonderful foundation on which to begin my research.
First, the conditions of the two sites being studied need to be examined for their exposure to nutrients from fertilizers, information which can gathered from the home-owners association for the Halifax Plantation location and the Volusia County Parks & Recreation department for the Tuscawilla Park location. Next I'll have to take to the internet to find what other sources of nitrogen and/or phosphorus my SMPs are exposed to which can help to differentiate between actual stormwater runoff and pollution originating from atmospheric deposition. The latter source research was addressed in a different article titled "Source Identification of Florida Bay's Methylmercury Problem: Mainland Runoff Versus Atmospheric Deposition and In situ Production" which found that more pollution was originating from atmospheric precipitation than from stormwater runoff.²
In preparation for next week's blog and actual water sample collecting, I plan to conduct further research into the appropriate amount of samples to collect before, during and after a rain event as well as  how much of said water sample will be needed to obtain an accurate measurement of nutrients.

Pedro UR; Canal Curiosity
Charles Faulkner has concerns of quality in the water around his neighborhood. My IRP will be to conduct a series of test in the canals and try to pinpoint a particular source which may be causing poor water quality. Mr. Faulkner has concerns that the city of Flagler Beach Water treatment facility may be a threat to the water quality due to previous assessment preformed by the Department of Environmental Protection.

Lilli UR -- Microplastics, What Are They and Why Should You Care?

Hello all and welcome to my weekly science-fest. This has been a busy, long, productive yet sad week. Other than receiving some disheartening news, I have continued working on my IRP which concerns micro-plastics in the ocean environment. After speaking with both Dr. Woodall as well as Angela I have come to understand that there are different types of oceanic plastic material. Which include what is referred to as micro plastics and are tiny fibers, and microscopic pieces of plastics that have degraded from larger pieces of plastics that have found their way into the ocean. But also includes micro-bead "plastics" which from my research I have come to understand are sometimes made of a wax material as opposed to plastics but these micro beads can also be made of plastics as well depending on the source of the beads. You can learn a little more here Oceanic Micro-Plastics, this an article I pulled from the DSC library database. I did not find much about general plastics in the ocean on my initial search, however there was some localized pieces about S. Korea, as well as Cambodia and the polar waters of the Arctic. There was also an article on the DSC library data base that spoke of how these micro-plastics specifically affect wildlife and the marine environment which you can check out here Micro-Plastics and the Marine Environment. 

Microplastics under a microscope

I also spent some time at the Marine Science Center this week with Mallory who taught me how to filter sea water and how to identify micro-plastics that may be present. Above is a nice example of what they actually look like under a microscope.Mallory informed that although they have yet to find micro beads they continue to look but they find an abundance of the fiber plastics (which are the hair like objects in the above picture). This was an amazing experience and one I am very thankful for. Not only did I get to see some micro-plastics and learn about the processes and materials used in not only finding but identifying them, I also got some great pictures of wildlife at their facility. Not to mention I almost got to see some whales off New Smyrna Beach but got lost on my way to where they were, next time gadget, next time.

I also learned about some pretty disturbing things when I was with Mallory, she spoke of how these micro-plastics end up in the ocean by trash dumping and then due to the UV rays of the sun as well as activity from wildlife such as nipping and attempting to ingest the larger pieces, become degraded to the point where they are so small the fish and other marine wildlife mistake them for food and ingest them, which as you might suspect is toxic to them. This information is also mentioned in both the first and second article I linked to so it was no surprise to hear Mallory mention it as well.  So in light of that particular piece of information I have included the photo below to perhaps encourage you to pack out what you bring onto our beaches and leave only footprints behind you in respect for our fellow creatures.

If this doesn't break your heart we cannot be friends :(

So my fellow bloggers, classmates and friends I leave you with one final thought and image. There is a giant patch of garbage that just floats around in the Pacific Ocean adding to the growing problem of these micro-plastics in our marine environments and it is called the Great Pacific Garbage Patch (no, really, it is). I was totally clueless about the existence of this "island" of trash that we, unfortunately, created until first taking Oceanography 101 with Dr. Woodall.  It just sits out there polluting our oceans, destroying our wildlife and yes, in case you were wondering, in some cases finding its way microscopically into your food.Which, in my opinion is not only a pretty big reason to care but (for me at least ) yet another reason to be a vegan!

Just a small portion of the Great Pacific Garbage Patch

So before you bring your groceries home in those plastic bags or purchase that "pretty" new fleece jacket consider the ocean and its inhabitants and remember -- Reduce, Reuse, Recycle, Refuse. There is also a website run by Dr. Maia McGuire from the University of Florida, where you can learn all about how you can get involved and make a positive impact on this growing problem which you can find here Florida Microplastics. There is wonderful information, educational materials for yourself as well as the public such as brochures and other pamphlets you can print if you are so inclined and a great pledge you can take to reduce your plastic footprint (not sure if this is a term but it should be ) which I have taken myself and would encourage all of you to consider as well. Dr. McGuire also provides information about the methods and materials she uses as well as a handy guide to identifying micro-plastics with some great pictures. She also details how one can become a volunteer and get involved in her efforts and provides some excellent resources as well as instructing you on how to log what you find and the hours you spend collecting, filtering and analyzing for those of you who may be interested. 
Until next week my friends, be happy, be safe and remember our friend Mrs. or Mr. sea turtle.



P.S. I have tested all of these links during the creation of this blog post but if anyone finds they are not working or you are unable to access the information please let me know so I can fix it as soon as possible.

Victoria UR- "They caught A Shark, Not THE Shark"

Found in an article titled Satellite Tagging: Expanded Niche for White Sharks a study using pre-dated satellite tags set on six different white sharks. It revealed the travel paths of each shark, as well as "pressure, temperature, and light-level data taken at 2-minute intervals" giving insight into where white sharks go, what temperature ranges they can survive in, and how often they visit the shorelines, near human activity.

Tagged white shark
(Great White Sharks are only called white sharks in the science community because there are not another white shark by name, so the "great" is not needed)

In another article called Vulnerability of the Oceanic Whitetip Shark to Pelagic Longline Fisheries, 11whitetips were tagged and tracked with pop-up satellelite archival tags (PAT)

Information from 8 of the 11 tagged sharks and when the tags popped up

For many catches, the method of actually catching the specimen can vary greatly depending on the target species. For the most part, a long line is used for a great range, with many hooks, giving a greater chance of catching multiple sharks, and a variety of species. A drumline can also be used, which consists of an anchor and a buoy with a long hook centered in between the anchor and buoy, which can only catch one specimen and limits total catch. Also, a drumline is usually used in deeper waters where a longline can be short or long depending on which line length is used in the water.

Drawn longline, shows how many possiblilities as well as the chance of bycatch.

Deanna, UR- Red Drum Studies

Since Red Drum is an extremely popular sport fish species here in Florida, and also known to be a decent meal, their populations are of interest for conservation reasons. Thusly, resulting in regular stock assessments and enhancement studies. One study I found focused on the movement patterns of adult red drum here in Florida lagoons. In fact this study was done in a northern part of the Indian River Lagoon and Mosquito Lagoon.


IRL and Mosquito Lagoon - location for movement
pattern study

For this study forty-four red drum were caught, tagged and released from May of 2006 through June 2007. Fish in this study were caught by various methods, either different types of nets (some targeting red drum schools), some were donated by local fisherman and others were caught on hook-and-line (which will also be my method when it comes to my IRP). And of these forty-four fish, "All fish exceeded the 457–685 mm (18–27″) total length slot size in Florida and were not legally harvestable" (Reyier, E.). These fish were sedated, had a few scales removed, coded acoustic transmitter was inserted in each fish, and they were weighed and measured. After the sedation wore off the fish were safely released. This study tracked the forty-four fish over the time period of May 2006 until September 2008, and most of these fish had returned to or remained in this estuary for this time period. Eleven of these fish had left the area and never returned and, ten had been tracked for several months than disappeared (suggesting death or removal of the tracking device). This study proves what I had previous learned (from the FWC website) that red drum remain in estuaries and other inland water bodies until they get larger and then move into the ocean (which seven of the eleven fish in this study were tracked actually did this) some returning multiple times before spawning and after spawning season.

Example of a tagged red drum.

Another study was done in Tamps Bay, and focused on stock enhancement focusing on recreational fisheries. This study took different information from stock assessments (age, mortality, population, catchability, voluntary release rate, etc.), and all things considered, this study determined that stock enhancement may increase the socioeconomic objectives associated with recreational fishing but do come at a cost. This was shown by the increase in the total fishing effort and the satisfaction (of the fisher) in certain stock enhancement scenarios is directly related to an increase in the amount of vulnerable fish Camp, V., 2014).

 

FWC's stock enhancement hatchery - this is actually for
 several different important marine fish
species and bivalves.

This study brought to my attention that stock enhancement for red drum is not a popular thing. In fact, the only study I have come across about it discusses how Florida only does small-scale stock enhancements for red drum, and most of which are research based (Camp, V., 2013). While Texas is known for large-scale red drum stock assessment (they release millions of red drum a year). This study states that stock enhancement in Florida is not large-scale due to fairly low survival rate of the released red drum. However, like this study states, could be due to "lack of stakeholder motivation to advance production level enhancement" (Camp, 2013). Which could simply mean the stakeholders are satisfied with the increased numbers of wild red drum over the last twenty years.

Chris Browne, UR - Smyrna Bacteria

E. coli

     Bacteria can be beneficial or harmful, and sometimes the amounts of bacteria present can be a normal setting for any marine coastline environment. Dr. Woodall has instructed me that the primary purposes of my IRP will include the datum results of bacteria in the Canal Street inlet, as well as researching the impact that bacteria has had on similar environments (Muirhead, 2006). Local, International, rural, and urban areas have had many studies done, as the where our waste ends up, is where our society would be wise to manage effectively.

Canal Street Inlet

     Bacteria can have detrimental consequences to our human health, as we live and work in the coastlines. Most coastlines are fished and harvested regularly (Cooke, 1976). The health of the organisms in these environments are important in many ways. Specifically the shellfish and benthic organisms that clean our waterways are in jeopardy. As stewards of our environment, keeping a keen eye on our micro biotic ecosystems (Drexler, 2014) will prove significant as they set the stage in the macro environment.

     Ranges of attempts have been made to address bacteria in our environment. Taking studies from the effects of disinfection of our own waste water could be considered (Blatchley, 2007). E. coli and other food borne bacteria is a common problem for urban environments (Ibekwe, 2011). Too much anaerobic bacteria can cause massive area deaths of beneficial plants and animals. Those areas, in turn can then become toxic other areas as tides move in and out. My IRP will focus on all these areas, and shed some light onto downtown New Smyrna.
