PurposeResearch
ObjectivesJR17001 focussed on Southern Ocean science in the Drake Passage and West Antarctic Peninsula. This is both a hotspot of climate-forced physical change and an area of global importance in relation to carbon and heat fluxes between the atmosphere and ocean. JR17001 included three workpackages, a NERC-Conicyt project ICEBERGS (seabed biology) and two ORCHESTRA projects (oceanography). These projects had differing operation areas from the open ocean of Drake Passage (Firing team), offshore from the NW Antarctic Peninsula (Brearley team) and fjordic inshore of NW Antarctic Peninsula (Scourse team).

The most inshore project, ICEBERGS, planned to sample transects from fjord mouth to inner most safe navigation along three retreating glaciers. The sample fjords were selected as those for which there was detailed spatial retreat history (courtesy of Alison Cook) and seabed bathymetry (collated by Floyd Howard). Thus seabed and water column physics, biogeochemistry and biology could be sampled along a gradient of age and glacier influence, from where glaciers had not covered for >60 years to where they were less than a decade ago. This three-year joint UK-Chile project required a wide skills pool of scientists from seven different academic institutions and a similarly diverse array of apparatus. Ultimately ICEBERGS goal was to quantify how glacial retreat was influencing nearshore systems and biology and what the medium-term consequences of this would be.

The glider programme, and associated Collaborative Antarctic Science Scheme (CASS) WaveGlider project led by Morales-Maqueda, forms part of Work Package 2 of ORCHESTRA, tasked with understanding subduction processes of heat and carbon in the Southern Ocean. To that end, a glider programme was designed to understand how mixed layers change over the summer period in response to seasonal warming, storm events and submesoscale ocean dynamics. The initially planned deployment of 4 Slocum gliders (2 with microstructure) was supplemented by a SeaGlider (through a collaboration with Louise Biddle and Sebastiaan Swart at the University of Gothenburg) and an autonomous surface vehicle, an SV2 WaveGlider. In addition to the glider measurements, ship-borne high-resolution flux observations were made using the Plymouth Marine Laboratory installed meteorological sensors, and overflights with the BAS MASIN Twin Otter Aircraft over the glider region from Marsh were also scheduled.

The Drake Passage hydrographic observations are part of ORCHESTRA Workpackage 3, on the effect of Southern Ocean interior circulation and exchanges with other ocean basins on heat and carbon transports and storage. We aim to monitor Southern Ocean water masses and circulation pathways and Antarctic Circumpolar Current volume and property transports by continuing a near-annual annual time series of high-quality repeat hydrographic measurements on GO-SHIP line SR1b begun in 1993. The hydrographic measurements are complemented by ocean current and underway surface ocean and meteorological observations and by the deployment of profiling floats which will monitor stratification and deep currents in the Scotia Sea over time.
