Telemetry data obtained from Fastloc GPS/GSM tracking of 7 grey seals (Halichoerus grypus) captured in the Seine estuary (France) in 2022 and 2023

Tracking data of 7 grey seals were obtained from the deployment of Fastloc GPS/GSM tags developed by the Sea Mammal Research Unit (UK). Full tag description is available at: http://www.smru.st-andrews.ac.uk/Instrumentation/GPSPhoneTag/. The tags include a wet-dry sensor from which haulout events are recorded, a pressure sensor providing detailed dive data, as well as a Fastloc GPS recording irregular locations when the seal is not underwater. Data is stored onboard and transmitted via the GSM network when the seal is in the reception range. The data provided here are the individual GPS locations of the seals fitted with these tags for an average duration of 135 days.

Credit
We thank the fieldwork participants for their help in capturing seals, as well as colleagues from the Sea Mammal Research Unit for the development of the tags and technical help. Field participants came from La Rochelle Université (CEBC, Pelagis), the Reserve naturelle nationale de l’Estuaire de Seine, and the Office Français de la Biodiversité (OFB). All procedures were in accordance with the ethical standards of the French Ministry of the Environment as seals were caught and instrumented under licenses delivered to Cecile Vincent by this Ministry. The project was funded by the "DREAL Normandie" for the monitoring of grey seals before the construction of the "Centre Manche" offshore wind-farm. The CEBC was subcontracted by BIOTOPE to conduct this study as part of the monitoring of marine mammals.

Statement

Data_type: Type of data provided (here GPS location)

Species: Seal species: Hg = Halichoerus grypus (grey seal)

Capture_site: Location of the seal capture

Seal_ID: Seal ID based on the species, location and number of previous individuals fitted with tags

D_DATE: Date and time (UTC 0) of the recorded Fastloc GPS location

LAT: Latitude of the Fastloc GPS location (in decimal degrees)

LON: Longitude of the Fastloc GPS location (in decimal degrees)

V_MASK: SMRU filter of the locations. V_Mask=0 is plausible, V_Mask=20 or 50 is rejected due to unrealistic swimming speed (but may still be true when the seal swims in fast tidal currents!), V_Mask=-1 could not be tested due to the lack of previous/next location
