Marine debris washed up on beaches on Goudier Island has been recorded since 2014. Surveys are conducted on a monthly basis when the station is occupied during the summer season. This data contributes to the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) Marine Debris programme.

Temperature data were collected from a tidepool at Rothera Point, Antarctica every two minutes from February 1999 to May 2000, with the aim of documenting tidal, diurnal and seasonal variability.

The data include size, sex, location and morphological measurements and of Muraenolepis specimens included in Fitzcharles et al. (2021). The morphometric data were primarily collected from fish captured during South Georgia Groundfish Surveys in 2003, 2004 and 2005, with additional data obtained from type specimens and extracted from published descriptions of Muraenolepididae. For genetic studies, tissue samples from the South Georgia specimens were supplemented by additional tissue samples from Muraenolepis in other parts of the Southern Ocean. Source, location and depth of capture are included for all specimens that were sequenced, together with sequence Accession Numbers (to the DNA Database of Japan) for Cox 1 and 16S rRNA sequences. The work was primarily funded by the Government of South Georgia & the South Sandwich Islands and was a component part of Elaine Fitzcharles'' PhD (University of St Andrews).

Three species of Antarctic marine invertebrate: Nacella concinna (limpet), Paraceradocus miersi (crustacean) and Sterechinus neumayeri (urchin) were subjected to three different rates of warming and a two month acclimation trial at 2 degrees Celsius. The rates of warming were 1 degree Celsius per hour, 1 degree Celsius per day and 1 degree Celsius per 3 days. Animals were evaluated to determine whether there was a universal stress response at the cellular level. Funding was provided from the BAS National Capability Grant, funded by the UKRI Natural Environment Research Council (NERC).

This is a physiological dataset for the Southern Patagonian limpet, Nacella deaurata. The limpets were collected from 2-6m depth in the Straits of Magellan near to Punta Arenas (53.164 S, 70.917 W) between Nov and the end of Jan 2018-19. A 2 month feeding experiment maintained N. deaurata at 1,4,8,11 and 14 degree Celsius for 2 months. Ingestion rate, absorption efficiency, absorption rate, oxygen consumption (uptake), scope for growth and mortality were measured. The thermal reaction norm for duration tenacity of field fresh subtidal and intertidal limpets, as well as subtidal limpets that were incubated at 8 degree Celsius for 2 months was investigated. The thermal reaction norm of radula scraping rates of field fresh limpets was measured. This work was funded by the Center FONDAP-IDEAL 15150003, ANID Chile and NERC core funding to the British Antarctic Survey.

This dataset comprises conventional stomachs contents data for the biomass-dominant species of mesopelagic fish, particularly myctophid fish (Family Myctophidae) in the Scotia Sea. The data were collected by depth-discrete RMT25 net trawls deployed between 0-1000 m between the Antarctic Polar Front and the South Orkney Islands. Samples were collected repeatedly at nominal sampling stations during austral autumn 2004, spring 2006, summer 2008 and autumn 2009 for analyses examining the trophodynamics of Southern Ocean mesopelagic fish and their role in the food web. The data are the quantitative measures of diet composition (prey abundance, frequency and mass) observed from microscope analyses of individual fish stomachs per species.

Water column acoustic data collected in the Scotia Sea (from 2009-12-23 to 2009-12-30) during cruise JR228. Multi-frequency (38,120 and 200 kHz) acoustic data were collected using a Simrad EK60 echo sounder. The dataset comprises of calibrated and processed 38 kHz volume backscattering strength (Sv, dB re 1m-1). Data processing was undertaken using Echoview and Matlab. Processed netCDF data files are made available as part of the NERC Southern Ocean Network of Acoustics (SONA) and the EU MESOPP project.

An opportunistic marine mammal survey through the Atlantic Ocean between the UK and Antarctica was undertaken in November and December 2020. The RRS James Clark Ross, was used to transfer cargo and personnel for the British Antarctic Survey (BAS) from the UK to Rothera Research Station, Antarctica for the start of the 2020/2021 summer season. The transit and station relief included stops at King Edward Point and Bird Island, South Georgia, Falkland Islands and Signy Research Station, South Orkney Islands. The journey took a total of 48 days. Two JNCC marine mammal observers were on-board as well as other dedicated observers. Marine mammal observations were made as opportunistic sightings and recorded along with geographical position and other metadata. This transit and subsequent survey was unique in its passage as few vessels journey down the centre of the North and South Atlantic and continue on down the Western Antarctic Peninsula. British Antarctic Survey will continue to make this journey twice a year and it could provide a platform for an annual marine mammal survey of the entire Atlantic Ocean.

This dataset contains occurrence records and associated metadata for the zooplankton species Calanus finmarchicus that were compiled from multiple open access databases. A file containing the corresponding background points is provided, along with gridded environmental variables for each season (Jan-Feb-Mar, Apr-May-Jun, Jul-Aug-Sep, Oct-Nov-Dec) and era (1955-1984, 1985-2017) that were assessed in this study. Together these data were used as input files for the MaxEnt ecological niche model within the peer reviewed article: Freer JJ, Daase, M, Tarling GA, (2021) Modelling the biogeographic boundary shift of Calanus finmarchicus reveals drivers of Arctic Atlantification by subarctic zooplankton, Global Change Biology. Finally, an R Markdown document is provided to enable data users to replicate the model optimisation and prediction steps using the input data files within this repository. Funding was provided by: UKRI Natural Environment Research Council (NERC): DIAPOD (NE/P006213/1), NERC and the German Federal Ministry of Education and Research (BMBF): CHASE (NE/R012687/1), Norwegian Research Council: Deep Impact project (300333).
