PurposeResearch
ObjectivesThe activities associated with research cruise JR17005 cover two NERC Changing Arctic Ocean projects: DIAPOD and ARISE

At each station, a series of activities were undertaken to provide samples to address the objectives of both DIAPOD and ARISE. Specifically, for DIAPOD, a series of nets (including Bongo opening closing, Mocness and ring nets) will be deployed to different depth horizons to study the depth distribution of Calanus and collect specimens for identification, lipids and determination of key metabolic rates (e.g. respiration and grazing). Subsamples of Calanus were collected for ARISE for biomarker analysis. CTD deployments collected complimentary data on phytoplankton biomass and community structure. A second full depth CTD was used to determine the vertical profile in stable isotopes of dissolved and particulate material, focusing on water mass end members and key oceanographic features. Standalone pumps collected large quantities of particulate material for biomarker analysis. Finally, a megacorer will be deployed to collect a sediment core to quantify the influence of terrestrial material on the Arctic marine ecosystem.
