Norsk Polarinstitutt seminar: “Polar phytoplankton under multiple stressors – the effects of ocean acidification under varying environmental conditions”, 22 March 2012, Tromsø

Date  & time: 22 March 2017, 10:00–11:00

Location: Norsk Polarinstitutt, Framsenteret, 6. etasje, Rom “Tre kroner”, 9296 Tromsø, Norway

Presenter: Clara Hoppe, Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research, Bremerhaven, Germany

In an era of dramatic anthropogenic perturbations of the global carbon cycle, the Arctic and Southern Oceans are experiencing rapid environmental changes, including ocean acidification, warming, sea-ice loss and changes in stratification.

Given their important roles in ecosystems and biogeochemistry, the responses of polar phytoplankton to climate change variables have received increasing attention in recent years. However, the interactive effects of multiple stressors remain poorly understood, as is the interplay of species-specific physiological responses and ecological dynamics.

Our group at the Alfred Wegener Institute (Germany) focusses on understanding the physiological and ecological processes that determine the effects of multiple stressors on polar phytoplankton. In this talk, I will present some of our recent work on the interactions between ocean acidification and other environmental drivers, including studies on natural phytoplankton assemblages and key species from the Southern and Arctic Oceans.

Dr Clara Hoppe works as a research scientist at AWI. Her current research focuses on the abilities of Arctic phytoplankton assemblages to compensate the effects of multiple drivers as well as on the controlling factors of Arctic spring bloom dynamics. Currently, Clara is a guest scientist at the Norwegian Polar Institute, working with Philipp Assmy.
