Seabed temperature readings from the South Georgia Patagonian toothfish longline fishery

This dataset presents temperature readings collected from the waters around South Georgia in the years 2019, 2021, and 2023 to 2025. From 2021 onwards, depth readings are also presented. The data were obtained using temperature loggers affixed to longlines operating in the South Georgia Patagonian toothfish fishery. These in situ measurements were conducted to monitor the water temperatures around South Georgia. The deployment of the temperature loggers was carried out by fishing vessel crew and fisheries observers working on behalf of the Government of South Georgia and the South Sandwich Islands (GSGSSI). The data were collated by the Centre for Environment Fisheries and Aquaculture Science (Cefas).

The collection and analysis of this data series was part-funded by the UK Government Blue Belt Programme in partnership with the Government of South Georgia and the South Sandwich Islands. The procurement of some of the temperature loggers was funded by Argos Froyanes Limited.
