Objectives

Cruise JR17006 was joint effort by the NERC-funded "Arctic PRIZE (Productivity in the Seasonal Ice Zone) and CHASE (Chronobiology of changing Arctic Sea Ecosystems) and the UiT-based research programs "Arctic SIZE". Arctic PRIZE is focused on the evolution of the Barents Sea shelf system from winter through spring to summer and this cruise was the third of three such cruises in 2018 (January, April and June). CHASE is a new NERC project focused on investigating the relationship between life history, physiology and biological rhythms in Arctic copepods and krill. Arctic SIZE is a new research initiative within UiT to investigate the ecology of the seasonal ice zone and JR17006 provided an opportunity for spring sampling.

Both Arctic PRIZE and CHASE projects were focussed on occupying stations along the 30E line of longitude to complete a suite of sampling that spanned the oceanography, water column optics and chemistry, phytoplankton communities and their physiological state, zooplankton response to light cycles and benthic communities. These summer data, at a time after the peak of primary productivity, will complement the set a winter data collected in the same locations in January 2018 and spring data collected in April 2018. The ultimate aim of Arctic PRIZE is to understand the balance between ice cover, nutrient concentration and phytoplankton dynamics to understand how the productivity of seasonally covered shelves will alter in a future arctic state. A key objective for PRIZE was the deployment and utilisation of robotic platforms (AUV and gliders) to extend spatial and temporal data collection. Further data were collected at stations along the northern Svalbard shelf and extending out into the deep Arctic basin and the sea ice zone. Two moorings were recovered (having been deployed in Sept 2017) and re-deployed at locations on the northern shelf.

60 stations were occupied ranging from a single CTD profile to full station with all project parameters measured. In addition there was recovery of 1 glider and 2 moorings and additional Norwegian-led sampling for the Arctic SIZE project. In total there were 285 gear deployments. Stations visited included those occupied during the 2017 JCR Changing Arctic Ocean cruise JR16006.
