Current Projects
Effects of a changing climate on
the habitat utilization, foraging ecology and distribution of
crabeater seals
Combinining animal movement, stable isotope analyses, whole-animal physiology, and novel survey technologies (UAS, satellite imagery) to investigate the differences in the trophic ecology, foraging success, and distribution of crabeater seals across a latitudinal gradient along the western Antarctica Peninsula (wAP)
Animal-Borne instruments to sample the coastal Southern Ocean
Deploying tracking tags on marine megafauna (Animal-Borne Instruments, ABI) offers a valuable supplement to more traditional ocean observing methods
Weddell seals as Antarctic oceanographers
Weddell seals are restricted to coastal waters of the western Antarctic Peninsula. We are going to the field to investigate their movement patterns and document the changes in the environment they utilize
Estimating the probability of exposure of marine predators to oil exploration seismic surveys
Developing a dynamic approach to estimate the likelihood that individuals from different populations of marine mammals could be exposed to idealized, simulated seismic surveys as they move over the continental shelf
Developing Metrics of Animal Condition and their linkage to Vital Rates: Further Development of the PCoD Model
Refining metrics associated with physiological measures of body condition that allow detection of pregnancy or the timing of reproductive suppression
