Cruise Inventory Information
| Long name | RRS James Clark Ross (74JC) cruise JR18006 |
|---|---|
| Short name | JR18006 |
| Objectives and Narrative | Rates of warming in the high northern latitudes are amongst the highest globally. One of the most obvious manifestations is the dramatic reduction in summer sea ice extent and thickness over the past few decades. JR18006 is the third in a series of three cruises to the Barents Sea exploring the biogeochemistry of the continental shelf seabed research within the Changing Arctic Ocean research programme, funded by NERC. The primary objective of the cruise was to collect a suite of pelagic and benthic samples across the 30? longitude water mass and sea-ice gradient occupied by the first and second cruises, JR16006, in 2017 and JR17007 in 2018. The report includes a description of the sampling and data collection across 5 benthic focus sites, a series of water mass stations, continuous atmospheric methane sampling whilst underway, experimental observations and sampling of sea ice at and beyond the ice edge achieved during July, 2019. These were investigated as part of ongoing effort aimed at understanding the effect of changing sea ice cover on organic matter quality, benthic biodiversity and function, biological transformations of carbon and nutrient pools, and resulting ecosystem functioning at the Arctic Ocean seafloor. The sites spanned 72 to 81 N but the furthest north site (termed B17) could not be visited due to strong sea ice conditions. The samples will be worked up over the coming years by a series of UK universities and institutes. |
