Dive data were obtained from telemetry studies performed on ten harbour seals (Phoca vitulina) and twelve grey seals (Halichoerus grypus) captured in the Baie de Somme, France, in 2008 and 2012, respectively. These seal individuals were fitted with Fastloc GPS/GSM tags, developed by the Sea Mammal R...

A dive event was registered by the tag when the seal reached depths exceeding 1.5 m, and different parameters were thus measured: start date and time, maximum depth, dive duration, post-dive surface duration, the “percent area” (to identify dive shape, cf. TAD index by Fedak et al., 2001), and nine intermediate depth points (each 10% of the dive duration).

Dive data were obtained from telemetry studies performed on ten harbour seals (Phoca vitulina) and twelve grey seals (Halichoerus grypus) captured in the Baie de Somme, France, in 2008 and 2012, respectively. These seal individuals were fitted with Fastloc GPS/GSM tags, developed by the Sea Mammal Research Unit (University of StAndrews, UK). These tags include a Fastloc™ GPS, a GSM modem (for data transmission), and wet-dry, pressure and temperature sensors, as well a microprocessor (for on-board data processing) (McConnell et al., 2004). A dive event was registered by the tag when the seal reached depths exceeding 1.5 m, and different parameters were thus measured: start date and time, maximum depth, dive duration, post-dive surface duration, the “percent area” (to identify dive shape, cf.
