The dataset comprises 78 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North East Atlantic Ocean (limit 40W) area specifically the JONSIS standard section in the northern North Sea, the standard Faroe Shetland Channel sections, to the East of Shetland and on the shelf edge. The data were collected during October 2007. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Fisheries Research Services Aberdeen Marine Laboratory.

A collection of raw format seafloor visual images acquired during a survey within the Greater Haig Fras Marine Conservation Zone (MCZ), central Celtic Sea, in 2012. This was the first in a series of surveys to be conducted in this location. A camera system mounted on the autonomous underwater vehicle (AUV) Autosub6000 was deployed during RRS Discovery cruise 377/8 (D377/8), and images were collected from four 4.7 km transect lines. The raw images are provided in this collection, available on request. The images are provided in a raw format unique to the Grasshopper 2 camera system. The aim of the survey was to undertake high-resolution acoustic seabed mapping and visual imagery in a Marine Protected Area, in order to highlight the capability of AUV technology for offshore seabed mapping and benthic assemblage assessment. The work was initially undertaken as part of a Defra-funded project "Investigating the feasibility of utilizing AUV and Glider technology for mapping and monitoring of the UK MPA network (MB0118)", Case study 2: Shallow-water AUV mapping off SW UK (https://nora.nerc.ac.uk/id/eprint/500733/), and the Natural Environment Research Council (NERC) funded Autonomous Ecological Surveying of the Abyss project (NE/H021787/1), involving scientists from the National Oceanography Centre (NOC), UK. Other supporting datasets available on request include AUV-based multibeam bathymetry, sidescan sonar and CTD data.

The dataset comprises 24 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the Norwegian Sea, North East Atlantic Ocean (limit 40W) area specifically in Faroese waters during February 2001. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Faroes Fisheries Laboratory as part of the Monitoring the Atlantic Inflow toward the Arctic (MAIA) project.

The dataset comprises 38 hydrographic data profiles, collected by a conductivity-temperature-depth (CTD) sensor package, from across the North Sea and the Celtic Sea areas including specifically the north east coast of England, between the Firth of Forth and Flamborough Head, and in vicinity of the Dogger Bank. The data were collected during July of 1998. A complete list of all data parameters are described by the SeaDataNet Parameter Discovery Vocabulary (PDV) keywords assigned in this metadata record. The data were collected by the Centre for Environment, Fisheries and Aquaculture Science Lowestoft Laboratory.

Multibeam bathymetry data were collected in the Clarion-Clipperton Zone (CCZ), Northeast Pacific Ocean, using a hull-mounted Kongsberg EM122 multibeam echosounder during RRS James Cook Cruise JC241 from 06/02/2023 to 25/03/2023, and JC257 from 08/02/2024 to 19/03/2024. Data acquisition began upon exiting the Costa Rican Econoic Exclusion Zone (EEZ), suspended within the Clipperton Island EEZ, and resumed upon exiting the Clipperton Island EEZ. Data were then acquired throughout the CCZ. This suspension was repeated on the return journey. The data were recorded using Kongsberg’s Seafloor Information System (SIS) in .all format, and CTD and model-derived sound velocity profiles were subsequently applied. The data were manually cleaned using swath and subset editors in CARIS HIPS and SIPS software version 10.4. A zero tide file was also applied. The data were collected to obtain a better insight in the biodiversity patterns and benthic habitat distributions within the CCZ, by scientists from the National Oceanography Centre, Southampton, UK as part of the NERC-funded Seabed Mining And Resilience To EXperimental impact (SMARTEX) project (NE/T003537/1).

The long term monitoring of water chemistry in Signy Island lakes is unique in polar limnology, in its duration (30+ years), detail, and range of sites. It details seasonal patterns of snow and ice cover, inorganic nutrient status and chlorophyll-a and includes vertical profiles of various physical chemical parameters. There are detailed data for several study lakes and twice/thrice yearly analyses for all the Signy Island lakes. Temperature and light climate has been studied in certain lakes using automatic data loggers. Micrometeorological monitoring with additional data loggers provided data on solar radiation (PAR, UVR), air temperature, humidity and wind conditions. Data are collected by chemical analysis, use of temperature, pH light probes and observation. The 'grand prix' was the sampling of 16 lakes in a short period (approx. one week), this was carried out perhaps two or three times a year. Approximately three to five lakes were sampled monthly or fortnightly in more detail, these were representative of the 16 lakes. Comparative studies were also undertaken in the Arctic. The long-term programme was established in 1971, although some observations were made in 1963/1964 and 1969/1970. The programme finished in 2004. 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.

The British Antarctic Survey holds one of the most extensive collections of Antarctic rocks and fossils anywhere in the world. These are predominately from the Antarctic Peninsula region and Scotia Arc, although there is also important material from areas such as the Ellsworth Mountains, Marie Byrd Land and the Transantarctic Mountains. Some of these specimens go back to the very earliest days of the Falkland Islands Dependencies Survey in the 1940s, and include collections made by the pioneer geologists at bases such as Hope Bay and Deception Island. Right from the outset, every specimen collected in Antarctica has been numbered and catalogued, and a vast reference archive is now available for use by the geoscience community. We currently have information relating to 150,000 field samples often with associated analysis data such as geochemistry. Additionally we hold a variety of data for nearly 500 marine cores. Metadata and data are stored digitally within a number of Oracle 10g database tables and for some datasets such as the type and figured fossil collection there is external access through a web interface. However, a significant number of datasets exist only in analog form and are held within the BAS archives organised by individual geologist. This abstract acts as an overview of the BAS geological data - both terrestrial and marine.

The palaeontology collection at the British Antarctic Survey is a unique and internationally important collection of specimens sourced predominantly from the Antarctic Peninsula and Scotia Arc. The collection was started in the 1940s and continues to be added to frequently through ongoing BAS research. Its importance lies not only in the fact that it is globally one of the main reference collections of Antarctic palaeontological material, but also in its high proportion of Mesozoic flora and fauna which can be used to understand evolutionary dynamics, continental movements and climatic changes over the past 250 ma. In addition to molluscs and other major animal phyla, the collection is particularly strong in plant material, ranging from fossilised wood and exceptionally preserved leaves to pollen and spores. Given the logistical challenges of sampling material from the Antarctic continent, this collection represents a wealth of taxa which were previously unknown to science and consequently houses a high number of taxonomic types. A project is underway to digitally catalogue the BAS Type and Figured fossil collection and make the data easily accessible to researchers worldwide. Currently the data from over 2000 fossil specimens are available online, together with high resolution photographs. Over the next year further specimens, including palynological samples, will be added to the database and photographs will be made available of the entire collection.

This list provides a check-list of the non-lichenized fungi reported from Antarctica that have been published in the literature or deposited in major culture collections. The list includes all macrofungi, filamentous forms and yeasts, together with some members of the Chromista (Straminipila) that have historically been considered as fungi. This compilation excludes lichens, as these species have been extensively listed elsewhere. Primary source data are from the collections and records held in the Biological Sciences Division at British Antarctic Survey and the Mycology Section, Royal Botanic Gardens, Kew. Secondary data is from publicly available specimen and culture collections and scientific literature. The list is part of an ongoing determination of the fungal diversity of the Antarctic region, and this version includes details of names, synonyms, taxonomy and at least one reference to an available record. Within these categories links are made between reported and current names, and all entries are bookmarked to individual references and citations. A details section is currently being developed to include hosts and substrates, this is very much a "work in progress" and is being regularly updated. Details on collection locations are also currently being added, and the information under region indicates at least whether the collection was from the Antarctic or sub-Antarctic , together with more information on location. These two fields will be expanded in the future.

SOMBASE is a tool for looking at marine molluscs in the seas around Antarctica. Using a database and the latest mapping technology it is possible to display all the places where a family, genus or species has been found on an electronic map. These maps show us how widely spread different organisms are and if they prefer a particular area or type of habitat. The database can also be used to address questions about biodiversity in the seas around Antarctica and how it's unique environment affects which animals are found there. SOMBASE contains comprehensive distribution records of Antarctic, Magellanic, and Sub-Antarctic Gastropods and Bivalves as well as records for many other species from the Southern Hemisphere. Based upon published records and British Antarctic Survey data these distribution maps form part of a biogeographic database, which also includes taxonomic, ecological and habitat data. The database contains information on over 3,250 species from more than 3,800 locations.
