The first day back at UNF we took two boats out on the St. Johns and traveled 20 miles upriver in order to sample water quality and view the anthropogenic effects.

| Boat 2: Capt'n Hackney |
We conducted a water sample test of the surface and bottom of the water using a Vandorn device. We also used a Secchi disk to test turbidity.
 |
| Trying to get the disk to sink was not easy in a ripping current! |
We collected a plankton sample that we brought back to the lab and analyzed for phytoplankton and chlorophyll content.
 |
| Determining the chlorophyll content. |
 |
| Identifying diatoms is no easy task. These ladies make it look easy! |

Getting the samples ready!

Overall I had a great time out in the boat all day. It's not every day you get to travel upriver 20 miles and observe the activities. The coolest thing that we saw was the Jacksonville port with a car tanker unloading! It was really cool to see where all of our products come from.
