Otago: Four nursing females were captured and fitted with SPLASH tags
(combined satellite and dive tags) and VHF location transmitters. The object:
to discover their foraging habits at sea and attendance patterns on-shore.

Sandy Bay, Enderby Island:
10 juveniles (4 male and 6 female) were similarly tracked.

The SPLASH tags have been removed and the results are:
Otago females have it easier than their sub-antarctic relations.
Check out the comparison below...

The SPLASH tag is
the foremost device.
The rear device is
a VHF transmitter
for local location.

The devices are fixed to neoprene
pads which are in turn glued to the
animal's fur. The device is removed by
simply slicing the neoprene pad in half.
The remaining half then falls off at the
animal's next moult, leaving no trace.
