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.

Nematode species were extracted from two species of bryophyte (Cephaloziella varians and Sanionia uncinata) in a vegetated gully on Rothera Point, Adelaide Island. Nematode species were extracted from 10 fixed plots: five control plots, and five warmed plots (covered with open top chambers for the duration of the experiment). Sampling occurred over eight days between 2007 and 2010. The total number of nematodes in each sample, along with the numbers of males, females and juveniles of each species, were recorded and expressed per gram dry weight of bryophyte colony. The numbers of gravid females of Plectus belgicae, along with the total number of eggs in gravid females, were also recorded at four of the samplings.

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.

This record consists of 3 different datasets covering the Adelaide Island and Arrowsmith Peninsula region of Antarctica: contours, spot heights, and lakes. The data have been produced for an updated version of the 'Adelaide Island and Arrowsmith Peninsula' 1:250,000 scale map, produced by the Mapping and Geographic Information Centre, British Antarctic Survey. The data are suitable for a 1:250,000 scale map but may be suitable for larger scales in certain areas. They have been created from source data ranging from 2022 - 2025. The datasets were created using a mixture of GIS software, primarily extracted from high resolution published elevation models, and digitised from Sentinel-2 satellite imagery. Exact details of each dataset can be found in the lineage statement. The data is useful for cartographers as well as scientists interested in the mapping of this region. The data is used on the map alongside further data published in v7.11 of the Antarctic Digital Database, November 2025 (coastline: https://doi.org/10.5285/cc0b73c0-3b53-40fb-ae84-b5dce4ac163a and rock outcrop: https://doi.org/10.5285/815525ca-cefe-4fbf-9224-3ee784e7de4e).

The dataset consists of 21 physico-chemical parameters (moisture concentration, pH value, electrical conductivity, the concentrations of total organic C and N, Ca, Cu, Fe, K, Mg, Mn, Ni, P, Zn, and those of water-extractable phosphate ions, sulphate ions, chloride ion, ammonium-N ions, nitrate/nitrite-N ions and dissolved organic carbon) measured in 29 soils gathered from along a latitudinal transect between Signy Island (60 degrees South) and south-eastern Alexander Island (72 degrees South) in November 2007-February 2008. Funding was provided by NERC grants NE/D00893X/1; AFI 7/05

This dataset comprises video and imagery captured around Rothera Point, Adelaide Island on the West Antarctic Peninsula between November 2023 and February 2024. The data was captured as part of a biodiversity survey on an area to the North of Rothera Research Station. Operations were conducted off small boats and allowed data to be collected in shallow waters between 10 m and 60 m water depth. The dataset includes: seabed imagery captured using a down-facing drop camera, video footage from a Boxfish Luna remotely operated underwater vehicle (ROV), timelapse imagery from a camera installed on the Rothera Research station watch tower and video and imagery of a sediment profiler experiment of the seabed. Data were collected by personnel at BAS, funded by the Antarctic Infrastructure Modernisation Project (AIMP) Runway Project.

This study investigated the status of dark septate (DS) fungi in Antarctic plant and soil communities, with the aim of determining the abundance of DS fungi in plant roots and rhizoids, their taxonomic affinities and their symbiotic status. Abundances of fungal hyphae were recorded in roots and rhizoids, and fungi were isolated and identified. Sequencing of ITS (internal transcribed spacer) regions of rDNA indicated that some isolates share taxonomic affinities with fungi of known symbiotic status. Synthesis experiments assessed the effects of DS fungal isolates, including H. ericae, on the growth and nutrient balance of their host plants. Seeds of Deschampsia antarctica and Colobanthus quitensis were collected for use in ecophysiological experiments.

Three plant species, the leafy liverwort Cephaloziella varians and the angiosperms Deschampsia antarctica and Colobanthus quitensis, were sampled from 12 islands across a 1480 km latitudinal gradient from South Georgia through to Adelaide Island. Samples were collected to determine the abundance of dark septate fungi in Antarctic plant and soil communities and the effects of these organisms on plant growth. Where the target species were found in sufficient numbers to allow sampling, it proved possible to collect at least 10 samples of each species. At least 10 soil samples were collected from each site where Deschampsia was found. Plants, with intact roots and soil, were transported back to the UK using cool and frozen stowage. Additionally, intact live plants were transported to the UK in an illuminated cabinet. Seeds of the two key species (Deschampsia antarctica and Colobanthus quitensis) were also collected at Bird Island and South Georgia. As the exact months of the data collection were not provided, and the metadata standard requires a YYYY-MM-DD format, this dataset has been dated as 1st January for start date, and 31st December for stop date.
