DOI 10.17882/91059 Tracking data of 10 harbour seals and 2 grey seals were obtained from the deployment of GPS Argos Satellite Relay Data Loggers (SRDLs) developed by the Sea Mammal Research Unit (UK). Full tag description is available at: http://www.smru.st-andrews.ac.uk/Instrumentation/GPSArgosTag/. The tags include a wet-dry sensor from which haulout events are recorded, a pressure sensor providing detailed dive data, as well as a GPS recording irregular locations when the seal is not underwater. Data is stored onboard and transmitted by satellite via the Argos system. The data provided here are both the individual GPS and Argos locations of the seals fitted with these tags for an average duration of 145 days.

47.8N, 43.7S, -53.6E, -62W
Data_type: Type of data provided (either GPS location or Argos Location)
Species: Seal species: Pv=Phoca vitulina (harbour seal), Hg = Halichoerus grypus (grey seal)
Capture_site: Location of the seal capture
Tag_number: Individual number of the seal fitted with a tag. One individual could be "numbered" differently on two consecutive field work if fitted with a new tag.
Seal_ID: Telemetry tag number
D_DATE: Date and time (UTC 0) of the location
LAT: Latitude of the location (in decimal degrees)
LON: Longitude of the location (in decimal degrees)
V_MASK: SMRU filter of the locations. V_Mask=0 is plausible, V_Mask=20 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
