List of fish species identified and cross-referenced by an integrative taxonomy analysis. Specimens were identified to the lowest taxonomic level using morphological features. A sub-sample of small muscle tissue from each individual was taken for DNA extraction and amplification of two mitochondrial genes, cox1 and the non-coding control region (CR). Special attention was given to larval and juvenile specimens. Samples were collected by fishery observers on board krill fishing vessels for the winter seasons between 2019 and 2024. Extra samples collected before 2019 were obtained from the biological archives at BAS including muscle and fin tissue as well as otolith samples spanning from 1988 through 2022. All samples were measured and photographed prior to be subsampled for DNA. Most samples were blast-freeze and stored at -20 degrees C or fixed in 90% ethanol. Tissue samples were stored in 90-95% ethanol and kept at -20 degrees C. Data resources from this project were used to developed enhanced identification guides for larval and adult fish species caught as bycatch within the Antarctic krill fishery. This is a Darwin plus initiative awarded to Philip, R. Hollyman under round 10 funding scheme, project reference DPLUS166.

This dataset consists of biomass data and diet composition of mackerel icefish (Champsocephalus gunnari) from the South Georgia groundfish survey, collected during scientific trawl surveys from 1986 to 2023. These data were primarily collected to produce estimates of mackerel icefish biomass to inform management of the icefish fishery, and to further our understanding of icefish ecology, distribution, and diet. Data were primarily collected by Martin A. Collins, Mark Belchier, Inigo Everson, Jude Brown, Phil Hollyman, Simeon Hill, Tom Marlow, Caradoc Jones, Rebecca Mitchell & Sue Gregory. Since 1990, the South Georgia groundfish surveys were funded by the Government of South Georgia and the South Sandwich Islands. Earlier surveys were funded by the US and Polish governments.

Blue carbon data for assemblages living on soft substrata (20m South Cove and Hangar Cove) and Rocky substrata (Cheshire Island) around Rothera Point Antarctica (2013-2015) in both winter and summer. All fauna larger than 1mm (soft substrata) and 3mm (hard substrata) were collected by suction samplers. All fauna were identified and then carbon values calculated for each species from dry mass and ash free dry mass.

Genetic profiling data relating to studies on Antarctic krill, Euphausia superba, that document the sequence of expression of genes over the moult cycle and the spatial-temporal expression of clock genes. This work was carried out to examine rhythmic behaviour patterns in this species - namely diel vertical migration and the moult cycle - and the functioning of the genes that underlie these behaviours. Circadian entrainment experiments were carried out twice during the Discovery 2010 summer cruise (cruise no JR177) using krill caught in nets at latitudes of 60S and 52S. Krill samples from each net were processed and preserved for subequent analysis using molecular biology technique to isolate canonical clock genes.

Automatic data loggers are often used to monitor environmental variables such as temperature (of air and soil), humidity, wind speed and radiation in microclimates where experimental or ecological studies are being carried out. Some loggers are only in operation for a few weeks or months while others have been run for several years. Loggers have been sited in a wide variety of locations from the sub-Antarctic (South Georgia), South Orkney Islands (Signy) various Peninsula sites (as far south as Alexander Island - 70S), and some continental localities (e.g. Victoria Land). These form an important data resource to the climate conditions experienced by Antarctic terrestrial organisms. Various types of logger are used. Sensors tend to be deployed at or near ground level and in and around particular types of vegetation, or other experimental sites, such as cloches. Loggers used include Grant, Delta-T, Campbell and Squirrels. Victoria Land data for Kay Island and Edmonson Point in 1995 and 1996 was collected under the BIOTEX 1 experiment of the SCAR BIOTAS (Biological Investigations of Terrestrial Antarctic Systems) Programme.
