Monday I came back to work, and instead of going to my office, I spent the day with the VA Sea Grant office at their SAV Teacher Workshop. Every year they have a species of concern
workshop and this year's focus was SAV: Submerged Aquatic Vegetation - mainly dealing with eelgrass which is the most common species around here. We got a lecture from one of the big SAV profs at VIMS, then went over an activity using data on SAV and water quality, and then we went in th
e field. It was great! I brought my snorkel and got to snorkel around the grassbeds. We saw a skate, lots of blue crabs, and some fish. Also, lots of amphipods and isopods which are little bugs that live in the grass. Our job was to do a few simple sampling jobs - 1. Take a Virnstein sample (the clear plastic contraption in the picture) which takes a small sample of SAV at one of the sampling sites to take back to the lab. 2. Pull a dip net down our transect for animals. 3. Pull up a piece of grass to test for chlorophyll. 4. Take a benthic core to see the root system of the grasses.
After taking all of ou
r samples, we brought them back to the lab and had to scrape the epiphytes (other things that grow on the blades of grass and block the sunlight) off the grass in order to run our samples. We put the grass through a machine that calculated the surface area of the blades, we ran chlorophyll samples, and we observed the live amphipods and isopods under a high-powered microscope in order to identify all of the different species. It was a great experience and my first time snorkeling at Goodwin Island!
