| Objectives and Narrative | Research summary for DIAPOD NERC Changing Arctic Ocean programme: Copepod species of the genus Calanus (Calanus hereafter) are rice grain size crustaceans that occur throughout the Arctic Ocean consuming enormous quantities of phytoplankton. These tiny animals represent the primary food source for many Arctic fish, seabirds and whales. During early spring, they gorge on extensive seasonal blooms of diatoms, fat-rich phytoplankton that proliferates both beneath the sea ice and in the open ocean. This allows Calanus to rapidly obtain sufficient fate to survive during the many months of food scarcity during the Arctic winter. Diatoms also produce on the main marine omega-3 polyunsaturated fatty acids that Calanus require to successfully survive and reproduce in the frozen Arctic waters. Calanus seasonally migrate into deep waters to save energy and reduce their losses to predation in an overwintering process called diapause that is fuelled entirely by carbon rich fat (lipids). This vertical lipid pump transfers vast quantities of carbon in the oceans interior and ultimate presents the drawdown of atmospheric carbon dioxide. Continued global warming throughout the 21st century is expected to exert a strong influence on the timing, magnitude and spatial distribution of diatom productivity in the Arctic Ocean. Little is known about how Calanus will respond to these changes, making it difficult to understand how the wider Arctic ecosystem and its biogeochemistry will be affected by climate change. The overarching goal of this project is to develop a predictive understanding of how Calanus in the Arctic will be affected by future climate change. At each station, a series of activities will provide samples to address the objectives of DIAPOD. Specifically, a series of nets (including Bongo opening-closing, Hydrobios and ring nets) will be deployed to different depth horizons to study the depth distribution of Calanus and collect specimens. |
