| Objectives and Narrative |
JR19002 on the RRS James Clark Ross integrated science from four funded programs, three CASS programs and several bolt-on collaboration projects. The work on board started in Sheldon Cove, Rothera, following base resupply and the laying of a mooring for the RaTS project (Mark Barham, BAS). The main components of the expedition were the final legs of the ICEBERGS and RACETRAX programs reoccupying the west Antarctic Peninsula fjord sites in Sheldon Cove (Rothera, Adelaide Island), Börgen Bay (Anvers Island) and Marian Cove (King George Island) sampled in 2017 and 2018. For the first time, small boat work was undertaken as part of ICEBERGS and RACETRAX in all three fjords. ICEBERGS is a 3 year NERC-CONICYT funded grant to University of Concepción (Chile), University of Exeter, Bangor University and BAS. The project aims to better understand through quantitative sampling the effects of glacial retreat on marine biological systems. The DEEP IMPACT project (Dr Dave Barnes) seeks to quantify iceberg scouring frequency below diving depths and a bathymetric survey for this project was undertaken in Sheldon Cove at the start of the cruise. In the early stages of preparation, the RACETRAX project, written to integrate into ICEBERGS, was awarded to Dr Amber Annett (University of Southampton), further diversifying the scope of ICEBERGS. The RACETRAX project aims to identify and characterise the nutrient mineral availability and origins in each of the fjord systems. Two CASS projects were linked to the RACETRAX project on JR19002: AEROBICS, an investigation of Antarctic eukaryotic adaptations and response to oxygen in benthic interstitial communities (Dr Mehul Vora), and FAnFARE, a project to generate the first direct measurements of sedimentary Fe flux along the west Antarctic Peninsula using the 224Ra/228Th disequilibrium method (Oliver Flanagan). An additional CASS project (Dr Carmen Falagan-Rodriguez) linked to ICEBERGS investigated the response of the microbiology of Antarctic fjords to freshwater flux and likely microbiological responses to increases in freshwater associated with ongoing deglaciation.
Several small self-funded projects completed the diverse science conducted on board. A continuation of the microplastics project (from filtered water and sediment cores) was undertaken by Tristyn Garza on behalf of Dr Alexis Janosik (University of West Florida). Julian Bloemenroeder (University of Hull) sampled meiofauna from recovered multicores to investigate the physiological impact of internal microplastics within key species. Professor Mark Furze continued the micropalaeontological sampling undertaken in 2017 and 2018 on behalf of Dr Anna Pie?kowski (University Centre on Svalbard). Tobias Ehmen (University of Exeter) undertook an investigation of the seismic oceanography of the fjord systems, following calibration of the EK80 multibeam at Börgen Bay, linked to the research on turbulence by his PhD supervisor Katy Sheen who sailed in 2017 and 2018. Felipe Salas de Freitas (University of Bristol) investigated the oxygen profiles of recovered multicores on behalf of the ICEBERGS team. The cruise ended with continuation of the marine bathymetric survey and benthic sampling along the Burdwood Bank initiated in 2018 as part of a Darwin Plus funded project involving the South Atlantic Environment Research institute (SAERI) and British Antarctic Survey (BAS). The aim was to gather data to help inform management decisions regarding Falkland Island Government marine spatial planning. The two expert marine geophysical scientists on board as part of the ICEBERGS program were key in maximising the data quality collected over the limited time of the survey. |
