So first, what is a HOBO data logger?
Well According to Onset, the company that produces these Magnificent Measuring Machines, A data logger is a compact, battery-powered device equipped with an internal microprocessor, data storage, and one or more sensors, or sensor ports aka it is a compact computer that measures things like Temperature, Water Level, Dissolved oxygen, but for this project this little guy is going to be used to measure water level, specifically along the Volusia county coast. So without further adieu here is the compact calculating computer being held by someone who needs to trim their nails and is obviously photo shopped into some generic stream....

After doing research Dr. Woodall and I just need to find a location suitable to drop the logger, that will include getting permission from a variety of people. This research will take a while to complete so I won't have my presentation ready until the fall most likely, but with the help of Dr. Woodall and her peers at FIU who are also conducting research like this we will be able to get important data to how our coast is experiencing climate change and be able to compare our data with others to possibly extend our data and graphs to all of the eastern coast.

If you'd like to read up on why this project is important NOAA has some simple articles about them that I'll link:
This is going to take time but with the help of Dr. Woodall I'm extremely confident that we will reach our goals and be able to contribute to the study of climate change.

Have you considered how you are going to relate your readings to the barometric pressure? Where are you going to find/measure this data? Also--what about fouling? What steps will you be taking to reduce its effect? And you say you are going to place this in a PVC pipe. How will water be able to enter it and reflect water-level changes?
ReplyDeleteWell I read that high pressure can result in lower tides and low pressure results in high tides at a rate of 1hPa to 1cm of water, so knowing that I think relating the two shouldn’t be that hard. As for reading it, I think anytime we make a reading we should collect a barometric reading as well, we could make a spread sheet displaying water level collected barometric pressure at time of data collection then using the 1:1 ratio be able to find our actual water level we could also compare that to average water levels possibly collected in the past.

To answer both of the PVC and fouling questions, I should’ve been more detailed, in one of the Onset videos they go over some examples of stills, they mentioned that it’s a good idea to make tiny slits in the pvc so that water can get in but small organisms and sediment cannot, I was going to get the PVC and drill holes in it then place a fine mesh screen over it that way it keeps any chance of fouling at bay and if needed the screen can be easily cleaned at the time of taking data readings.
In the video "tips for deploying" it talks a lot about the importance of taking barometric pressure readings. In fact, part of the software includes barometric pressure accommodations. Someone on the webinar mentioned a link you can go to for possibly linking to local data..I believe they said that readings must be within 10 miles of our deployment. Try looking at usairnet.com I haven't had a chance yet to explore this website.
