Transects will incorporate insofar as possible:* Closely-spaced full depth CTD/ADCP stations plus profiles of PAR irradiance, bio-optical properties and fluorescence (EoI 9, 57, 310, 573, 585, 596, 635, 911).* Collection throughout the water column at stations of water samples for tracer, chemical and biological analyses including oxygen isotopes, carbon parameters, inorganic and organic nutrients and trace gases, and for biomass on deck incubation experiments to evaluate auto and heterotrophic activities (EoI 9, 573, 585, 596, 635, 911).* Deployment of moored instruments along each transect to measure temperature, salinity, current velocities, sedimentary fluxes and sea level for at least one year (EoI 9, 57, 310, 573, 585, 596, 635).* Deployment on the shelf of autonomous water samplers to collect weekly samples for tracer analyses (EoI 9).* Deployment of ice-hardened surface ocean drifters across the coastal and slope break current systems, measuring temperature, salinity, sea level pressure and location (EoI 9, 310, 573).* Air-sea heat and freshwater flux and meteorological measurements (EoI 9, 573, 585).* Swath bathymetric surveys of the complex shelf and slope terrain, both to assess local circulation and mixing processes, and to detect geological/glaciological phenomena such as iceberg scour (EoI 9, 237, 310, 573, 596).* Sedimentological observations including coring and biostratigraphy (EoI 596, 635)* Turbulent mixing measurements (EoI 9, 310, 573).* Continuation of hydrographic sections poleward beneath ice shelves and/or sea ice using autonomous underwater vehicles (AUVs) such as Autosub (EoI 9) and hot-water drilled access holes (EoI 310).* Use of AUVs to measure sea ice thickness distribution on the Antarctic shelf and slope (EoI 57)* Use of autonomous underwater vehicles an…
