Abstract
Goose barnacles (Lepas australis) were found attached
to satellite-tracking and time-depth recording
(TDR) instruments carried by two lactating
Subantarctic fur seals (Arctocephalus tropicalis)
from Marion Island. We report on the movements of
these seals, both of which crossed the Subantarctic
Front. Barnacles surrounding the temperature probe
of one TDR device did not appear to directly influence
temperature recordings, although disturbances
to recording accuracies by other highprecision
devices carrying goose barnacles are considered
likely.
