On the swaying boat called the RV San Jacinto, Jessica Geiskopf is tossing aside black and dead oysters. Dark, silky mud leaks out of the shells, having suffocated the mollusks on the floor of Galveston Bay. They are discarded into a pile away from the healthy oysters.
It’s just after noon on a Tuesday in late January, and about ten miles from the Seabrook Marina and Shipyard outside Houston, Geiskopf is spending hours on the water surveying the oyster population.
