The Sea Mammal Research Unit Instrumentation Group

Marine mammals may travel to remote regions of the ocean and may spend a high proportion of their time underwater.  The opportunity for direct visual observation is limited, so we need to use instruments attached to animals to collect and relay data.  These generally record depth and location but instruments may also record physiological, oceanographic or other behavioural parameters (even the sound and visual field of animals). 



SMRU’s internationally renowned Instrumentation group develops a range of marine mammal telemetry tags for use by SMRU and other researchers.
