This dataset consists of measurements of conductivity, temperature, depth, fluorescence, optical backscatter, oxygen, and turbulence microstructure collected from gliders, as well as temperature depth measurements from moored Acoustic Doppler Current Profiler and turbulence microstructure measurements from microstructure profilers. The ADCP was moored to a depth of 476m in Ryder Bay, West Antarctic Peninsula, between 01 March 2016 and 12 December 2016. The mooring was deployed on R/V Lawrence M Gould cruise LMG16-01 and recovered on RRS James Clark Ross cruise JR16003. NOC and BAS Gliders were deployed during the 2014/2015 and 2015/2016 Antarctic field seasons and MSS Microstructure profilers were deployed between February and August 2016 from Rothera, within the Ryder Bay area. This cruise formed the field component of NERC Discovery Science project "What controls the influx and mixing of warm waters onto the polar ocean shelves?" The main objectives of the project were: 1. To quantify, describe and understand the spatial and time-varying patterns of lateral and vertical mixing on the West Antarctic Peninsula shelf. 2. To resolve the dominant mechanisms driving lateral and vertical heat fluxes, with a specific focus on understanding how and where heat from the deep ocean waters is transferred to the upper ocean. 3. To understand the role of key shelf-edge processes in controlling these phenomena, in particular by understanding and quantifying the importance of these processes in causing intrusions of warm, saline deep-ocean waters onto polar shelves. To deliver on these objectives, the project used data from both traditional and novel oceanographic platforms, with the aim of describing how warm waters move from shelf edges to coasts, where land-based melting of ice can occur. Discovery Science Research Fellowship grant NE/L011166/1 was led by Dr James Alexander Brearley at the National Environmental Research Council (NERC), British Antarctic Survey (BAS), Science Programmes. Funding ran from 09 June 2014 to 08 June 2019. Glider, moored ADCP and MSS microstructure profiler data have been received by the British Oceanographic Data Centre (BODC).
