The increasing need for continuous monitoring of
the world oceans has stimulated the development of a range
of autonomous sampling platforms.
One novel addition
to these approaches is a small, relatively inexpensive data-
relaying device that can be deployed on marine mammals
to provide vertical oceanographic profiles throughout the up-
per 2000 m of the water column. When an animal dives, the
CTD-Satellite Relay Data Logger (CTD-SRDL) records ver-
tical profiles of temperature, conductivity and pressure. Data
are compressed once the animal returns to the surface where
it is located by, and relays data to, the Argos satellite system.
The technical challenges met in the design of the CTD-SRDL
are the maximising of energy efficiency and minimising size,
whilst simultaneously maintaining the reliability of an instru-
ment that cannot be recovered and is required to survive its
lifetime attached to a marine mammal. The CTD-SRDLs
record temperature .....
