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.
