This dataset set describes the developmental stages and the molecular barcoding of Terebellidae larvae identified from diver-collected samples on 2021-04-22 in Ryder Bay near Rothera Research Station, Antarctic Peninsula, Antarctica. Photographs were collected at seven stages across the larval development. Development was captured from the trochophore stage where the polychaete larvae were bound in mucus to the free swimming planktonic metatrochophore to the nectochaete stage. Molecular barcoding was performed using the 18S rRNA gene at the British Antarctic Survey. Funding: This study was funded by core funding to UKRI NERC-BAS.

The ICEBERGS project aimed to understand the impact of retreating coastal glaciers upon benthic marine ecosystems along the West Antarctic Peninsula (WAP). This was a collaboration project between University of Exeter, the British Antarctic Survey, Universidad Catololica de Santiago de Concepcion and Bangor University. During three research cruises (JR17001, JR18003 and JR19002) between 2017 and 2020, biological specimens along with other scientific data and samples were collected from three coastal fjords (i.e. Marian Cove, Borgen Bay and Sheldon Cove). The biological samples were collected using mainly a benthic Agassiz trawl and some using a Hamon grab and they were either preserved in ethanol or dry. Funding: The funding for this grant was provided from NERC and from CONICYT Chile (NERC-CONICYT; NE/P003087/1).

This dataset comprises data on the water content of various terrestrial invertebrates on Signy Island, from 1984 to 1996. Species include native mites (Gamasellus racovitzai, Halozetes belgicae, Alaskozetes antarcticus, Stereotydeus villosus), springtails (Archisotoma brucei, Parisotoma (now Folsomotoma) octooculata, Cryptopygus antarcticus) and the non-native midge (Eretmoptera murphyi). Live samples were collected monthly at Bernsten Point, Elephant Flats, Gourlay Peninsula and Factory Bluff over both the summer and winter season. This data were collected as part of a long-term monitoring programme on terrestrial habitats in the maritime Antarctic. This dataset was supported with NERC core funding to BAS.
