Plankton, minuscule organisms, are spread across the oceans, covering nearly three-quarters of the planet. But a warming world is throwing plankton into disarray and threatening the entire marine food chain. Think of Calanus, a type of zooplankton, as “little batteries that are floating in the ocean,” said Jeffrey Runge, a zooplankton ecologist who recently retired from UMaine. Calanus hibernate through winter, hiding from predators. But in November in the Gulf of Maine, David Fields, a zooplankton ecologist at the Bigelow Laboratory for Marine Sciences, was out hunting them. He aims to understand what’s happening to planktonic species as the ocean warms and its currents shift. Amy Wyeth, a zooplankton ecologist, is starting a new plankton sampling and habitat monitoring program for the Maine Department of Marine Resources to give the state “more predictive power,” to forecast the movements of right whales and help Maine’s lobster fishery avoid whales entanglements with endangered North Atlantic right whales.
