Marine bio Camp - day 4 recap

Today's Itinerary
Morning session
Take RWU boats out for plankton sampling - one boat deploys a 150μm zooplankton net, the other deploys a 20μm phytoplankton net;
Using Van Dorn bottle, collect water samples and set-up primary productivity analysis (using the light/dark bottle technique);
In lab, use microscopes to examine the plankton samples - sketch and ID five phytoplankton and five zooplankton;
use spectrophotometers to measure chlorophyll concentration in samples filtered yesterday;

Afternoon session
Head to Fogland Beach for some fish seining along the shore and salt marsh;

Evening Lecture
Fish Biology

Highlight of the Day
Catching a 20-inch striped bass in the beach seine

Lowlights of the Day
1) Lion's mane stings
2) For tomorrow's Winkler titrations I wondered if I should use glass or plastic graduated cylinders. Are the high schoolers careful enough for the glass ones? I don't know...they're pretty fragile...and tippy (the cylinders, not the kids!)...oh what the hell, let them use the good stuff. Any bets on what I did while setting up? I decided to go with plastic.
