July 9, 2017 — On Friday, July 14, Dr. Jeffrey Runge will give a talk titled “Plankton, Right Whales, and Change in Gulf of Maine Ecosystem.”
The seminar will take place in Brooke Hall at the University of Maine’s Darling Marine Center beginning at 10:30 a.m. The event is free and open to the public, but registration is requested at tinyurl.com/y87uxsmw.
The Gulf of Maine ecosystem rests at the southern edge of the vast subarctic biome that stretches across the North Atlantic to the Barents Sea above Norway. The subarctic character and biomass of the Gulf of Maine plankton support the northern right whale population as well as the region’s distinctive fish and seabird communities. Ocean currents in the northwest Atlantic and in the Gulf of Maine work to sustain these subarctic properties.
Recent changes in the timing and abundance of zooplankton coincide with changes in right whale sightings, including a decline in number since 2010. In his talk, Dr. Runge will explore scenarios of future changes to the plankton in the wake of recent warming and ocean acidification.
