The effect of instrument attachment on the surface temperature of juvenile grey seals ( Halichoerus grypus ) as measured by infrared thermography
Previous research has highlighted the importance of minimising hydrodynamic drag from biologging instruments fitted to marine mammals. However, there is a need to investigate other possible impacts of instruments on animals. The aim of this study was to examine the effect of deploying instruments on...

Previous research has highlighted the importance of minimising hydrodynamic drag from biologging instruments fitted to marine mammals.

Infrared (IR) thermography was used to record the surface temperature of two juveniles that had been fitted with heart rate recorders and mounting straps for the attachment of a time depth recorder. When animals were fully wet and inactive, the surface temperature pattern was unaffected by instruments.
