Samantha- CUR, Intro Part II

Participating in Sea grass surveys.

Hello. My names is Samantha and I am continuing my undergraduate research at Daytona State College.  How I became involved in science began predominately with my interest in the Miami Dolphins. Football fan ---> scientist, weird. Well I should start off by saying I am weird.  I was born and raised in New Jersey around obnoxious, Italian, die hard Giants fan, my family(whom I love).  My dad however decided to be an outcast and become a Dolphins fan(mainly because he loves Dan Marino).  Anyways while my obnoxious family insisted I become a Dolphins fan I urged the argument, "Giants play unfair because they are giant.  The dolphins are cute and sweet therefore, fair."  Give me a break I was 4.  This perception I had for Dolphins along with yearly visits to SeaWorld led me to my future dream of becoming a dolphin trainer.  Typical kid stuff right?  I was fascinated by the marine life at Sea World especially the mammals.  Jumping through rings and splashing around with the alluring grin.  Lights flashing and trainers whistling, it seemed as though Marine Mammal training at SeaWorld was the greatest job in the world.  Soon after my 19th birthday however I came to find out I did not want to work at Sea World at all.  What i failed to realize was that a dolphins' smile is natures greatest deception.  No aquarium, no tank, however spacious it may be can begin to duplicate the conditions of the sea.   My feelings for captivity had changed drastically over the year and that is when my aspiration in becoming a marine mammal trainer came to an end.  No longer did I want to engage my time and knowledge presenting alongside of Shamu.  I wanted to protect Shamu and every other animal being held in captivity for show.  Well, Im not Rick O'Barry.  However I do have a great desire in protecting marine organisms as well as the habitat and environment surrounding.

           In 2013 I moved to Florida and began participating in volunteer opportunities in the area  pertaining to promoting and educating others about conserving the marine environment.  

I was able to partake in seagrass surveys conducted by Marine Discovery Center which gave me an introduction to water quality and how it can be effected naturally or anthropogenically.  Last semester I was able to land a class with Dr. Woodall where who encouraged my science career and helped me achieve what I have today.  I began my first undergraduate research project pertaining to the result of Anthropogenic Pollution discharging into Canal Street Canal which is being continued this semester.  In the Spring of 2017 I plan to graduate with my AA in Marine Sciences and transfer to hmm well somewhere (although I have colleges in mind I have decided on one specific) focusing on biology and conservation of the marine environment.  My goal now and in my future is to be able to educate the public on anthropogenic pollution in the marine environment and find ways to conserve all of the wondrous nature that this planet bestows upon us.

Mike Introduction

Howdy everyone. My name is Mike Bradley and I am 26 years old. I was born in Connecticut but I moved to Florida 16 years ago. I live in Bunnell, Florida with my wife Jen, my 1 year old son Finley. I am an avid outdoorsman, I like hiking, hunting, shooting and above all else my life revolves around fishing. I always tell everyone that if all I had was a fishing pole and a tent by a river I’d be set for life. I left my job as a lawn technician for a pest control company to pursue a degree in environmental science technology.

Emily UR- Introduction

Me, diving at Epcot!

Greetings! My name is Emily Reyes; I'm 21 & graduating this spring with my A.S. in Environmental Science Technology. Upon completion, I intend to leave Florida for an undetermined amount of time to traverse the country from coast to coast experiencing all that I can and seeing as many natural parks as possible. Returning to "adulthood" in Florida after my journey, I plan to finish the required prerequisite courses at Daytona State to allow me to transfer to the College of Environmental Science and Forestry in New York. I was born and raised on Long Island in a very urban setting but I've always been drawn magnetically to nature. From as far back as I can remember I've looked to the night sky with complete amazement and walked barefoot in the grass with infinite gratitude for this planet and all its inhabitants. I couldn't be happier to have discovered environmental science as a career path as everything I love to do takes place in the great outdoors!

Step-sister Stella (left) & Korra (right)

Here in Florida, where I've been living for two years this July, I've just been having oodles of fun. Currently, I'm employed at Zoom Air, a zipline adventure course in Tuscawilla Park. When I'm not at work, I'll take advantage of any and every opportunity to go diving, surfing, fishing, on a day trip or just take the time to read. On day one of this year, a beautiful dog wandered into my life and I named her Korra. She's currently living with her step-sister and her alpha while I learn a bit more about being a pack leader myself. During this final semester of my degree, I'm really excited to be able to work in the laboratory environment and begin analyzing samples collected from the field. I love knowing that when it comes time to find a place to settle, I'll be able to rely on my own skills and knowledge to determine the health of the environment in said settlement area and how it impacts myself and others. In the long term picture of life, I hope to find myself working on a research station in Antarctica for a little while but we'll see where this life thing takes me.
I look forward to working with everybody as we all advance in our respective fields!

Renee Moody, UR: Salutations and such...

Hello fellow scientists!! I am Elizabeth Renee Moody (Renee is the name most likely to garner a timely response from me) and I am excited to begin my undergraduate research with Daytona State College.

My first foray into environmental science came from helping my grandmother in her garden. I will never forget how good fresh string beans are or the exhilaration of being seven and sneaking pearl onions right out of the ground and before their time because the slightly sour, early onions are best. Grandma Moody began my lessons in respect for our earth and how important it is to our own survival (her simple terms: Bad Dirt and Bad water = bad food). She also taught me that one person can make a huge difference though I don't think she meant to teach me that. That was a happy accident. ;) 

I also have an awesome immediate family that keeps me inspired!

(Right to left) Brian, Alex and Skye!

My fiance, Brian, put life back into my desire to help our planet three years ago and after a lot of hard work I'll be graduating with my AS this spring(FINALLY!!) He also shares my nerdy loves like Star Wars(notice his shirt) and comic books. (He's a die hard Hulk fan, I'm a Captain America and Deadpool fangirl)
The tall, gangly one is Alex my step son. He is 14 and getting started on his Eagle Scout project (so HUGE KUDOS from me to the Eagle Scouts out there!!) I am crazy proud of him and he gets along great with me and my little girl: Skye.
Skye is 8 and says she wants to do something with animals when she grows up. She is "so jealous that mommy gets to do real science". I just remind her she is only in third grade and I'll let her tag along when I can. lol

Second to my love for my family is my love of plants!! In particular carnivorous plants! I own three myself: two pitcher plants pictured below and a camera shy bladder wort. I have been captivated by a Florida native species of pitcher introduced to me by DSC's own Dr. Ray Emmett. I have become so enamored with our native pitcher that I plan to make them the stars of my research this semester. I would like to know more about the conditions of their preferred habitat with hopes that I can help Dr. Emmett discover more specimens and determine what conditions would be favorable for pitcher plant seeds to establish in. 

This is Poppit my first tropical pitcher plant.

This is Behemoth(AKA Beh), my newest tropical pitcher plant.

Poppit (top left) was a gift from Brian and is in the top 5 favorites of all the gifts he ever got me. Along with a coffee tree currently in a giant tea cup shaped pot on the porch. She's a little sad looking from the cold weather right now and preferred not to be photographed. ;)
Behemoth or Beh for short (below to the left) I rescued from the discount rack of a really cool plant nursery in Deland: EFG Orchids. As their name implies they specialize in orchids. Their prices are a bit high but their plants are healthy and the staff is very knowledgeable.

Here in Florida we have a different sort of pitcher plant, the hooded pitcher plant which is in the family Sarraceniacea according to Dr. Emmett which grows in a clumping fashion with tall horizontal pitchers rather than the vining growth and hanging, trumpet like pitchers seen in Poppit and Beh who are part of the Nepenthes family(per hours of google picture searches and comparisons). Hopefully I'll have some pretty pitcher pictures to show everyone a comparison next post as Poppit has finally started making some new pitchers despite the cold snap and I plan to visit my Floridian buddies over the coming weekend to see how the cold and wild boar have been treating them.


I have also come to be recognized (quite by happy accident) by my talent and enthusiasm for Geographic Information Systems(GIS). So if anyone would like to incorporate some mapping but aren't sure exactly what kind or how to let me know I love to help! Oh and spoiler alert: Provided that I get my handheld technology problem taken care of I will be using several neat GIS apps provided by ESRI such as the Collector and the Operations Dashboard. The app names are links to the official ESRI information pages for the apps for anyone who may be interested in using them or just wants to learn more.
Well I do believe I've gotten my ramblings out of the way. I can't wait to learn more about my fellow students along with my pitcher plants this semester!

And because Dr. Woodall seemed quite adamant we should have a picture of ourselves on here...

Mason: Surfacing worms

     This morning as I was checking on the worms and spraying the soil I observed that container four's worms were closer to the surface if not on the surface while the other three were not visible due to them being deeper down in the soil. This could be due to the fact that container four has the highest concentration of fertilizer and the worms are trying to escape the fertilizer.

Mason: All Wormed Out

Hi, I am Mason Sylvester from Daytona State College working on my Earth Worm Project. I have listed additional information about earth worms and why they matter in our ecosystem and what fertilizer can do to them click on the links to access these blogs. Worm Plan The Burrowers
      Set up for my project began on Monday, December 7, 2015. The worms were placed and set in their containers following the procedure plan I created.

Materials

• 4 containers16.5 inches x 13 inches x 6 and 5/8 inches
• 4 potatoes
• Scotts Southern Lawn Food 32-0-10

• ROYAL Ds3 Digital Scale
• Shovel
• 10 gallon bucket
• soil
• table
• 40 Canadian Night Crawlers
• Scotts Black Duct Tape
• Pyrex Measuring  Cups (4cup and 8 cup)

Procedure

1. Gathered Materials listed above
2. Set up table in area with a consistent temperature and light
3. Dug one foot below surface and gathered soil into a 10 gallon bucket  from unfertilized ground
4. Prepped clear containers with black duct tape to block light from entering through the sides of the containers and reaching the soil. 
5. Cut the potatoes into halves three times for each piece giving me 8 pieces per potato. Following this  dice the potatoes into approximately  .5 inch piece.
6. Measure the potatoes into 4 12oz piles
7. Measure out 12 cups of soil for each of the 4 containers.
8. Place12 cups of soil and 12oz of potatoes in each container
9. Label the containers 1 through 4
10. Measure out 1 gram of fertilizer, 2 grams of fertilizer, and 10 grams of fertilizer.
11. Put 1 gram of fertilizer into container 2
12. Put 2 grams of fertilizer into container 3
13. Put 10 grams of fertilizer into container 4
14. Thoroughly mix the contents of each container
15. Seperate worms into 4 groups of 10
16. Place 10 worms in each container
17. Spray each container daily with 50 squirts from spray bottle filled with dui water
18. Observe worms activity and fatalities and record the data for the duration of experiment

If you have any questions, suggestions, comments, and or information to share please feel free to post on this blog.  I will continue to blog through the duration of the experiment.

Samantha, UR- What is a watershed?

Jim Cantore, an American meteorologist traveled a small Georgian town asking people, "What is a watershed?" Easy, if you're standing on the ground right now, just look down.  You as well as everyone around you are standing in a watershed.  A watershed is an area of land which drains into a body of water be that a river, stream, ocean estuary or bay.   Wherever you live drains to some water body, therefore you live in a watershed. In the United States and Canada, all of the water from the East of the Continental divide runs through different rivers and system, eventually flowing into the Atlantic Ocean while all of the water West of the divide flows into the Pacific.  

Watersheds are important because the streamflow and the water quality of a river are affected by things, human induced or not, happening in the land area "above" the river-flow point.  In this modern industrialized age our waters are becoming more contaminated with each passing year.   New Smyrna Beach is a highly active watershed with water coming in and out of every coast of the Island.  February, 2015 Volusia County participated in a 400 million dollar plan to protect water resources in the area.  This plan included; replacing septic tanks near springs and rivers, cleaning stormwater and improving wastewater treatment.  Although I did not see any mention about educating the public I believe that with enough data we could speak to the city in doing so. Volusia county coastal area is a complex, dynamic natural system compromised of barrier islands, estuarine systems and mainland watershed.  Canal Street Canal leads into the Indian River Lagoon which has five water quality monitoring stations.  I was able to attain information Canal Street Canal is a man- made subterranean canal, the contributing watershed is approximately 170.6 acres with a 5'x8' box culvert running along the south side of Canal street from the river westward of the FEC RR tracks which was recently upgraded in 2009/10. That becomes an open ditch and continues westward to Hickory Street intersection where the cross -section more so reflects a ditch or swale and should be considered the upstream most location.  The canal has an array of interconnected open swales, ditches as well as direct piping connections that feed into the canal.  This is all referred to in the city's Stormwater Master Plan.  I soon plan to attain this plan as well as the design plans for Canal Street. 

Angela, CUR - I've created a plastic bin monster...

Three weeks ago I found a plastic bin with a Japanese or Chinese symbol on it at Stonefield Beach State Wayside, Oregon. As mentioned in the post "Tsunami Debris?", my husband wouldn't let me put it in the car so I left it in the parking area thinking someone from the Oregon State Parks and Recreation Department would collect it. Today we went back so I could collect plastic, while my husband looked for agates.

Plastic Bin Monster

To my surprise, the bin was still there and it was filled with plastic pieces people must have collected at the beach (and one dog feces bag). Also, I'm not sure if three weeks of rain could've cleaned the bin this well, or if someone in the neighborhood (there are houses within walking distance) rinsed it off and brought it back so people could drop off their findings (?). Either way, evidently people are willing to pick up and dispose of plastic debris, but due to Oregon's "pack it in, pack it out" motto, there are no trash receptacles of any sort. I plan on looking further into this to see what I can do to either get someone to pick up the plastic trash, or what I could put out there that I could collect and dispose of once a month.

Letters from the Russian (Cryllic) alphabet

On today's hunt I was hoping to find pieces with foreign looking writing on it, of which I found several including one with letters from the Russian alphabet. Additionally, once I got down on my knees to pick small colorful pieces out of some wrack, I found plastic pellets! During my entire research on Florida's beaches I found three (four if you count the blue one, see image below) resin pellets, so I partially assumed large quantities were an urban myth; however, once I realized they were on this strip of beach, I came across dozens. I didn't have the proper equipment to collect them per International Pellet Watch's standards, so these few will become part of my personal collection and next time my focus will be on properly collecting pellets using metal tweezers to pick them up and an aluminum pouch for storage.

Three resin pellets, two beads, and potentially a
blue resin pellet found in FL, 2013.

Samantha, UR- Garbage of Canal Street

Busy street coming off local business thruway leading to man made canal

Canal Street, a very imperative historical thruway for the locals as well as tourists for many reasons, my reason being the water quality that lies beneath.  As most of us are aware that the south end of this street cuts off into a subterranean man made canal and in recent posts, my classmates and I have discussed this canal as one of our major sample sites for our research. 

View from south of the Canal
towards the lagoon

A huge concern found about this body of water is that in September my classmates and Dr. Woodall, as well as I read that this canal oxygen concentrations measured at 1.23 mg/L.  This meant that the canal was depleted of oxygen and very or little no life was probably able to survive in that body of water during that time.  In Angela’s recent post, “Oregon Observations applied to Volusia County,” she stated her concern for the lack of knowledge of runoff and wastes (especially plastics) being distributed into the surrounding storm drainage systems, which then lead into our lagoons.  I found this information very interesting and thought I would do some research myself about one specific Canal that I have been studying and just happens to be located right next to a storm drainage system as well as a busy commercialized road. As a child growing up in New Jersey I too remember being aware that storm drains are dumping into the river constantly with signs on each drain stating so.  I never realized the lack of this in my local area especially being located in Volusia County, which due to location, is highly susceptible to flooding.

of Canal with no indication
of leading into river

“The canal has an array of interconnected open swales, ditches as well as directs piping connections that feed into the canal, which is referred to in the storm water master plan,” says Kyle Fegley, a city Engineer of New Smyrna Beach. I do not have the full information on The Storm Water master plan and the Canal street design yet but I plan on attaining them and studying further.  I believe that the water quality in this specific body of water is significant to the Indian River Lagoon and the concern of land runoff. To begin my research, this morning I walked down Canal Street, which is the street, leading right to the Canal to look for anything I could find that may help my research.

notice all of the butts and plastics right near

I noticed a lot of garbage around the streets and businesses, things such a cigarette butts, plastic bottles, caps, receipts and even a pacifier!  The amount of garbage I found was unbelievable I even found some plastics in the water noting the tide was outgoing and it had rained in the last 24 hours.

Angela, CUR - Oregon Observations Applied to Volusia County

Imagine something in your house springs a leak – in my case it was the toilet tank – while it is certainly pertinent to soak up the water and get rid of it, you also need to shut off the source because otherwise you will be cleaning up water forever, and ever, and ever…to infinity and beyond.

That is how I feel about plastic in the ocean. While there are potential solutions in the works to collect some of the debris floating out there, such as the Ocean Cleanup Array, we need to stop the problem at its source – or in plastic’s case: sources.

During my Individual Research Project (pertaining to plastic on Florida's beaches), I learned plastic ends up in the ocean via various means, including shoreline garbage dumps, shipping vessels, visitors to the beach, as well as rivers and storm drains. The following observations pertain to keeping plastic from entering the last two of those contributors in Volusia County.

Observation 1: My new town in Oregon uses tall bins with lids for my recycling – the same type of containers provided for your regular garbage. While living in Deltona, at the end of every weekly waste collection day I came home to a road littered with recyclable items. I blame this on the small lidless collection containers. Further, on my drives along 415 to Daytona Beach, I witnessed plastic and cardboard items being jettisoned from these bins as vehicles whizzed by and created gusts of wind. Sadly, I’m no longer at Daytona State College, but should the opportunity for a community improvement project arise: could a group of students convince the local waste management services to change the recycling bin design to help keep plastic from entering rivers and storm drains?


Observation 2: Until my research project, I was unaware that waste can end up in rivers, e.g. a cigarette thrown out of a car window or small plastic debris from fireworks can get washed into storm drains and then into a river. Walking around my new environment, both in the suburbs and in the middle of the city, I am constantly made aware that storm drains dump into rivers; I don’t remember seeing anything of the like in Deltona. If I had to do another Geographic Information Systems project at Daytona State College, I’d be interested in mapping storm drains, rivers, and other bodies of water in Volusia County. Once a map is made, if there are any storm drains dumping into any bodies of water, I’d do field research on those spots. Any findings during this research may also be applied to a community improvement project.

Samantha, UR- Nutrients and the Indian River Lagoon, We need to take more action !

Agricultural lands drain about 70 percent of nutrients - phosphorus and nitrogen- that end up in the St. Lucie River and the Indian River Lagoon, the state department of Environmental Protection Estimates.  The water district tests for nutrients monthly in nine locations in Martin and St. Lucie counties including the four major canals, Ten Mile Creek and the St. Lucie Rivers North and South forks.  DEP has established St. Lucie Watershed Basin Management Action Plans (BMAP).  BMAP is the "blueprint" for restoring impaired waters by reducing pollutant loading to meet the allowable loadings established in a total maximum daily load(TMDL).  It represents a comprehensive set of strategies--permit limits on wastewater facilities, urban and agricultural best management practices, conservation programs, financial assistance and revenue generating activities, etc.--designed to implement the pollutant reductions established by the TMDL. These broad-based plans are developed with local stakeholders--they rely on local input and local commitment--and they are adopted by Secretarial Order to be enforceable. The link below shows the sights that are under control by the BMAP.

http://www.dep.state.fl.us/water/watersheds/docs/bmap/bmap_activities.pdf

Under this plan however, state agencies make no effort to identify heavy polluters including the St. Lucie's watershed, where river runoff flows through several large canals and other tributaries into the lagoon and river, a Treasures Coast Newspaper investigation found.  Critics say BMAP is a nebulous approach that doesn't tackle pollution hotspots. The plan covers too broad of an area, calls for too-infrequent progress checks and requires no site inspections to ensure landowners make needed changes, they say. This system lets pollution flow unchecked for up to five years. At the point, the state examines whether water quality has worsened, but it imposes no penalties on landowners who don’t reduce nutrients, said Mark Perry, executive director of the Florida Oceanographic Society.  The nine locations are tested by the water district monthly for nutrients.  However, if nutrient levels surge, no one searches upstream for polluters.  The districts environmental permits have no nutrient limits or reduction targets, including agriculture.  GPS maps show most land in the watershed is agriculture. The rest is a blend of urban and undeveloped land.  Environmental Engineer, Gary Gofroth, crafted a 25-page analysis on nutrient runoff in local basins.  The district reviewed and denied to comment.  Gorforth estimates that 1.7 million pounds of nitrogen and 385,000 pounds of phosphorus flowed from agriculture lands to St. Lucie River in 2013-2014.   

Angela, CUR - Tsunami Debris?

Something I learned during and after my Individual Research Project I conducted during the fall semester of 2013: no matter the season, I’ve always been able to find plastic on Florida’s east coast.

Imagine my disappointment, during my first visit to Oregon in August 2014, I found one single plastic item - a miniature version of a My Little Pony that a child probably left behind. The beaches we visited on the Oregon coast had a multitude of visitors, some even grilling on the beach (meaning they had trash, but they took it back home). I also noticed the water was calm and there was very little wrack; however, on Florida’s east coast I could still collect bags full of plastic sans wrack, but most of that plastic was probably left behind by visitors and had not washed up, which is what I’ve really been after.

Barnacles on plastic, found at Roads End State Park, OR

Plastic basket, found at Stonefield Beach State Wayside
October, 2015

After moving to Oregon end of May, the West coast still provided a dismal amount of plastic during the summer – I found one lonely food container, due to its pristine condition it was more than likely left behind by someone. In October, however, after the first two storms of the season, we drove out to Oregon’s coast to look for agates. Three different locations, including the area where I found the little plastic pony in 2014, were littered with wrack, and in that wrack I found plastic!  Additionally, the coast was pelted by turbulent waves; at Stonefield Beach State Wayside, I headed north while examining the wrack, after about 40 minutes I turned around and a big plastic basket had washed ashore.

The basket was covered in algae and bivalves, and on each side it had a Japanese looking symbol. Did I find my first Tsunami debris? Admittedly, it could’ve also fallen off a fishing vessel. Through Facebook contacts I found out the symbol indicates the number two, and is used in Japan as well as China – so my basket may not have any ties to Japan whatsoever and be of Chinese origin.

I would’ve loved to take the basket home, but due to its condition my husband didn’t want it in his car. I carried it up to the parking area and left it under a state park sign…feeling like I littered. 

Samantha, UR - Hypoxia and Nutrients leading to a disturbance within the estuaries

While Hypoxia may be permanent or intermittent, it is most commonly manifested as a seasonal disturbance, appearing in mid to late summer after vertical stratification prevents replenishment of deep water dissolved oxygen (DO).  Stratification separates a body of water into layers. This layering can be based on temperature or dissolved substances, like oxygen.  In estuaries there is a signifiant division between freshwater and saltwater resources making up the stratification of the water.   On the surface or upper layer of the canal, saltwater holds less dissolved oxygen than freshwater and the stronger the river flow, the higher the oxygen concentrations.  Our water was hypoxic with a salinity of 9.9 parts per thousand, which is also pretty low.... Which brings me to the conclusion of fresh water being brought  and should be higher in oxygen, this was not the case.... Maybe this fresh water was contaminated with so many nutrients that this is what then caused oxygen depletion due to abundant amount of organisms undergoing respiration, leading to a hypoxic dissolved oxygen measurement.

Image of Hypoxia in Washington Estuaries mid - late summer

Which brings me to the fertilizer ban.  It is said that hypoxia seems to be more common in the late summers, which is around when we noticed our canal was hypoxic... contributing to the idea that these subterranean canals have a water consistency of organisms going through respiration.... this had to have been taking place so rapidly within the fresh water before it even saw the "light of day" that it makes me believe maybe this has to do with that freshwater coming in through the canal is highly contaminated with nutrients such as nitrogen of phosphorus coming from fertilizer possibly.  We know that nutrient levels were high, and oxygen was low... which gives us enough information to come to this conclusion.  There are two approaches you decide whether nitrogen and phosphorus are limiting nutrients in a water body.  Firstly involving the us of TN/TP ratio ( total nitrogen/ total phosphorus ratio).  The other involves the use of Phosphorus threshold value.  Calculating a relatively simple ratio can sometimes provide a useful clue as to the relative importance of nitrogen or phosphorus toward the abundance of algae in a water body.  For information on how to do so... refer to the link below.  Any suggestions ?
