Dan Costa's lab at UC Santa Cruz has been studying elephant seals
at Ano Nuevo for several decades, but his lab also works at many
other locations. Today, a sea lion that his lab tagged at San Nicolas
Island in southern California ventured all the way up to Ano Nuevo
Island!
So, a team of researchers went to the island to recapture the sea lion
and recover the instruments, which included a time-depth recorder
to record diving behavior and a satellite tracking / GPS tag to record
the path of the animal. The tracking tag did not work perfectly,
resulting in some gaps in the track, but it still shows the movement
from Southern California all the way north to Ano Nuevo!
Graduate student Elizabeth McHuron will be using these data in her
PhD dissertation focused on California sea lion behavior.
