Year-long mooring dataset from beneath George VI Ice Shelf between January 2012 and January 2013. Contains turbulence mooring data from two instruments initially at 2.57 m and 13.57 m beneath the ice base. High resolution 3D velocity data and temperature data at two instruments are included, as well as low-resolution thermistor data. The processing of this data was funded by a grant from the Natural Environment Research Council, NE/L002507/1.

This dataset comprises conductivity, temperature and depth (CTD) casts which were deployed around Rothera Point, Adelaide Island on the West Antarctic Peninsula between November 2023 and February 2024. Data were captured as part of a biodiversity survey on an area to the north of Rothera Research station. Operations were conducted off small boats and casts sampled shallow waters between 10m and 60m in depth. Data comprises parameters such as pressure, salinity, density, turbidity and more in addition to conductivity, temperature and depth. Data were collected by personnel at BAS, funded by the Antarctic Infrastructure Modernisation Project (AIMP) Runway Project.

Profiles of turbulent kinetic energy dissipation and the rate of thermal variance dissipation were observed beneath Thwaites Glacier in the grounding zone region of the Eastern Ice Shelf as part of the International Thwaites Glacier Collaboration MELT project. Using a Rockland Scientific VMP-250 turbulence profiler, five individual profiles were obtained in a 20-hour period between 10th-11th January 2020. Funding source: NSFPLR-NERC: Melting at Thwaites grounding zone and its control on sea level (THWAITES-MELT) NE/S006761/1

Variability in temperature, salinity and velocity was observed approximately 1.5 m beneath the base of Thwaites Glacier in the grounding zone region of the Eastern Ice Shelf as part of the International Thwaites Glacier Collaboration MELT project. Using a borehole deployable turbulence instrument cluster, the average temperature, salinity and velocity was observed over a 15-minute period every 2 hours. Funding was provided by NSFPLR-NERC: Melting at Thwaites grounding zone and its control on sea level (THWAITES-MELT) NE/S006761/1.

Conductivity, Temperature and Depth (CTD) profiles were collected in the grounding zone region of Thwaites Glacier Eastern Ice Shelf in January 2020 as part of the International Thwaites Glacier Collaboration MELT project. Using a borehole deployable CTD system (SBE49), 15 profiles were collected over a period of 4 days between January 9th and January 12th to observe the hydrographic structure of the water column. The profiles extended from the ice base (520 dbar) to approximately 5 m above the seabed (575 dbar). Funding was provided by NSFPLR-NERC: Melting at Thwaites grounding zone and its control on sea level (THWAITES-MELT) NE/S006761/1.

Autosub Long Range (ALR) was deployed along the Modified Warm Deep Water Inflow beneath Ronne Ice Shelf in February 2018 as part of the Ice shelves in a warming world: Filchner Ice Shelf system large grant, Antarctica. The vehicle was equipped with a Seabird Conductivity-Temperature-Depth (CTD) sensor, two Teledyne Acoustic Doppler Current Profilers (ADCPs), one upward looking and one downward looking, and a nose-mounted Rockland Scientific International MicroRider turbulence package. ALR followed a rhumb line course beneath the ice shelf, running approximately parallel to the 400 m isobath. The vehicle alternated between stretches of bottom tracking and top tracking in a square-wave pattern, while maintaining a minimum clearance of 80 m between the vehicle and the ice base or seabed. Funding was provided by the UK Natural Environment Research Council Large Grant Ice shelves in a warming world: Filchner Ice Shelf system, Antarctica (Grant No. NE/L013770/1).

The dataset contains processed model output of future simulations of the East Antarctic Ice Sheet using the Ua ice dynamics model (https://github.com/GHilmarG/UaSource). Simulations were run for 200 years comparing the impact of both an intermediate (RCP4.5 emissions scenario) and extreme (RCP8.5 emissions scenario) as well as maintaining the current oceanic regime or switching to one dominated by circumpolar deep water intrusions. A reference run with constant present-day forcing is also included to assess the relative impacts of the various forcing scenarios. This work was primarily funded by the Natural Environment Research Council, grant number NE/R000719/1. James Jordan, Hilmar Gudmundsson and Adrian Jenkins received funding from the European Union''s Horizon 2020 research and innovation program under grant agreement no. 869304, PROTECT. Bertie Miles was also supported by a Leverhulme Early Career Fellowship (ECF-2021-484).

UTLs were used to determine whether whole animal acclimation had occurred in R. perrieri on heated settlement panels in the Antarctic. The panels were placed at 15m depth at two sites (South Cove and North Cove) near Rothera Research Station, Adelaide Island, Antarctic Peninsula (67.06861 S, 68.125 W). Heated and non-heated panels (one each of control, +1, +2) from the South Cove and North Cove sites colonised by R. perrieri were transferred to a 60 L jacketed tank with aerated sea water at the same temperature as the ambient sea water (0 degrees Celsius) and connected to a thermocirculator (Grant Instruments Ltd, Cambridge, UK). The temperature was raised at 1 degree Celsius h-1 with the temperature limit of each animal noted when they no longer responded to tactile stimuli. Funding was provided by the NERC grant NE/J007501/1.

This dataset compiles fish length and weight measurements from the RMT-25 net hauls carried out on Discovery 2010 cruises (JR161, JR177, JR200) in the Scotia Sea, Southern Ocean in spring 2006, summer 2008, and autumn 2009. The dataset comprises of the station net hauls only. Research cruises were led by British Antarctic Survey aboard the RRS James Clark Ross. Net hauls were conducted along a transect from the Antarctic Polar Front to the sea ice zone in the Scotia Sea. Hauls included in this dataset are depth stratified (1000-700 m, 700-400 m, 400-200 m, 200 m to surface). Individual fish lengths, and weights were measured on board. Where weights were not measured, length-weight regressions have been used to estimate fish weight. This data set accompanies the paper by Belcher et al. in Marine Ecology Progress Series, titled, Respiration rates and active carbon flux of mesopelagic fishes (Family Myctophidae) in the Scotia Sea, Southern Ocean.
