Introduction
|
Weddell seals are one of the top predators in Antarctic waters, yet very little data exist on their overwinter diving and foraging behavior. Given the lack of data on both Weddell seal ecology and the oceanography of the Ross Sea during the winter, Weddell seals outfitted with Conductivity Temperature (CTD) tags will yield highly valuable biological and oceanographic data. Specifically, We will use Weddell seals as autonomous oceanographic samplers to (A) assess behavioral changes of top marine predators in relation to intra- and inter-annual changes in their physical and biological environment and (B) produce an unprecedented oceanographic dataset to create predictive habitat models and then distribute these data to a broader scientific community.
