Movement of Pinnipeds

August 2014 - June 2017


Participating Agencies

  • NOAA Natl Marine Laboratory

Problem statement: Data associated with marine mammal tracking are often collected but the measures associated with data and the underlying movement process make it challenging to understand space use, interaction among individuals, and learn about movement patterns. So What? Why this research matters: The ability to formally make inferences about marine mammal space use and movement can lead to improved understanding of these important aquatic species. Collaboration/Partners: This project is in collaboration with scientists at the National Oceanic and Atmospheric Administration. Research That Informs Decisions: Formal statistical models that account for the various sources of uncertainty in marine mammal telemetry data will lead to a better understanding of mechanisms that aid in the management of these aquatic wildlife populations.
