Climb aboard our floating classroom, the 90' Research Vessel the Robert G. Brownlee, for an exploration of the San Francisco Bay like no other! After an introduction to this magical estuary, you can help us set a net to sample what fish are swimming through the waters below. We'll help you identify and even touch the fish we see... will we catch a shark, bat ray or any of over one hundred other surprising fish we've seen?? Then we pull up a bottom sample and see what all that mud has hidden inside. Last but not least, we'll peer into the world of plankton, the engine that drives the whole ecosystem! Must be at least 5 years old to board; all children must be accompanied and supervised by an adult; close-toed shoes required.
