Distribution of mesopelagic fish in the Scotia Sea from RMT25 and pelagic trawls deployed from RRS James Clark Ross and RRS John Biscoe
Mesopelagic fish were sampled in the Scotia Sea using a 25 m2 opening and closing rectangular midwater trawl during five research cruises on RRS John Biscoe and RRS James Clark Ross. Nets sampled discrete layers, from the surface to 1000 m during austral spring, summer and autumn. The data include 17726 individual fish records from 66 taxa, the most abundant of which were myctophids of the genera Electrona, Gymnoscopelus, Krefftichthys and Protomyctophum and bathylagids (Bathylagus sp.). Length (standard length, total length or pre-anal fin length) was measured for the majority of specimens (16837), with sex and weight data also collected for many. The work was conducted as part of the BAS Ecosystems Programmes funded by the UK Natural Environment Research Council.
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.
The dataset contains a current inventory of vascular plant species and their attributes present in the flora of Britain and Ireland. The species list is based on the most recent key to the flora of Britain and Ireland, with taxon names linked to unique Kew taxon identifiers and the World Checklist of Vascular Plants, and includes both native and non-native species. Attribute data stem from a variety of sources to give an overview of the current state of the vascular flora. Attributes include functional traits, distribution and ecologically relevant data (e.g. genome size, chromosome numbers, spatial distribution, growth form, hybridization metrics and native/non-native status). The data include previously unpublished genome size measurements, chromosome counts and CSR life strategy assessments. The database aims to provide an up-to-date starting point for flora-wide analyses. This dataset will be available under the terms of the Open Government Licence https://eidc.ceh.ac.uk/licences/OGL/plain Full details about this dataset can be found at https://doi.org/10.5285/9f097d82-7560-4ed2-af13-604a9110cf6d
