Using the power of models to protect whales from possible ship-strikes

Abrahms Lab, News /

Written by Dr. Anna Nisi We have been building cutting-edge models of species distributions for four great whale species – blue, fin, sperm, and humpback whales. One key threat to the great whales is collisions with shipping vessels, and identifying places where ship-strike risk is high is essential for informing mitigation actions like vessel slow-downs. Our next step is to […]

Field updates: Readying the 2023 season

Abrahms Lab, Updates from the Field /

After Assistant Professor of Biology and Boersma Endowed Chair Dr. Briana Abrahms and her team deployed GPS-audio wildlife tracking collars on African wild dogs and lions during the summer of 2022, Dr. Abrahms and Dr. Kasim Rafiq, a postdoc in the Abrahms Lab, have been working with industry collaborators to build AI models that detect behaviors (such as hunting) and hunger levels
