Collection and preservation of open ocean water samples from stations along a transect up the east coastline of Greenland and then across the Fram Strait to Svalbard during May 2018 & August 2019. Two cruises in total to cover annual changes, both on board the James Clark Ross (RRS). A standard CTD cast was deployed to collect the samples, depths were surface and the chlorophyll maximum, selected to support zooplankton net sampling and other on board experiments. Research assistants from SAMS (Scottish Association for Marine Science) were responsible for the sample collection on JR17-005, Dave Pond of Stirling University was responsible for collection on JR18-007. Elaine Mitchell of SAMS was responsible for the sample analysis and data processing. Funding was provided by the DIAPOD - NERC Thematic grant - Changing Arctic Ocean (CAO) programme - NE/P006213/1

Collection and preservation of open ocean water samples from stations along a transect up the east coastline of Greenland and then across the Fram Strait to Svalbard during May 2018. The cruise was to observe spring bloom conditions, on board the RRS James Clark Ross. A standard CTD cast was deployed to collect the samples, depths were surface, the chlorophyll maximum and a deep sample, selected to support zooplankton net sampling and other on-board experiments. Research assistants from SAMS (Scottish Association for Marine Science) were responsible for the sample collection on JR17005, Elaine Mitchell of SAMS was responsible for the sample analysis and data processing. Funding was provided from the DIAPOD - NERC thematic grant - Changing Arctic Ocean programme - NE/P006280/1.

Collection and preservation of open ocean water samples from stations along a transect in the Barents Sea over the course of a year from July 2017 - July 2018. Four cruises in total to cover seasonal changes, two on board the James Clark Ross (RRS) and two aboard the Helmer Hansen (RV). A standard CTD cast was deployed to collect the samples and depths were selected to support Primary Production experiments on board the ship, with deep samples representing 1 % PAR. Research assistants from SAMS (Scottish Association for Marine Science) were responsible for the sample collection and Elaine Mitchell of SAMS was responsible for the sample analysis and data processing. Funding was provided by the Arctic PRIZE - NERC Thematic grant - Changing Arctic Ocean (CAO) programme - NE/P006302/1.
