This dataset summarises the raw GPS locations obtained by satellite tracking of two southern right whales tagged at South Georgia island on 28th January 2020. One whale, genetically identified as a female, was tracked for 117 days (4,860 tag locations provided) and travelled ~5818km including a short period of time at the ice edge. The second whale, genetically identified as a male, was tracked for 238 days (8,492 tag locations provided) and travelled ~9,885km, including migration through the national waters of Argentina, Uruguay and Brazil. Funding: EU BEST 2.0 Medium Grant 1594, DARWIN PLUS award DPLUS057 and funding from the South Georgia Heritage Trust and Friends of South Georgia Island.

These are light level and activity data collected from BAS geolocators that were deployed on 4 Leopard Seals hauled out on Bird Island, South Georgia. Tags were deployed between May 2003 and June 2013. One seal Y5282(B4942) was tracked during two non-consecutive years using two different identification flipper tags. There are three data types for each seal a) the unprocessed light sensor data b) the unprocessed activity (wet/dry) data and c) The estimated positions estimated using the BAStag and SGAT packages in R. All files are in the CSV format and each folder has a readme.txt file describing the data structure of the files within. The data are reported in detail in Staniland et al. 2018 ''Long Term Movements and Activity Patterns of an Antarctic Marine Apex Predator: The Leopard Seal'' PLOSone
