Sarah is interested in understanding the complex feeding dynamics of marine mammals in temperate and Arctic environments. Her research focuses on determining the biological and physical conditions necessary to support successful feeding under current environmental conditions. Sarah applies new technology to record the fine-scale movements of large whales from the air and underwater to determine when and where they are feeding and what their encountered prey field looks like. She uses oceanographic sampling instruments to determine at what depth and abundances prey are found (e.g., zooplankton) and the associated physical properties of the water column (e.g., temperature and salinity) near tagged animals to assess the quality and quantity of their prey field. Combining information about the predators and their prey, she is able to identify key feeding areas throughout their range, assess the nutritional status of different demographic groups of whales and evaluate how climate induced shifts in prey distribution and abundance may impact feeding conditions in the future.
Current research project
Through a collaborative research study, we are testing whether the availability of Chinook Salmon is sufficient to support a healthy Southern Resident Killer Whale (SRKW) population. We’re using aerial and underwater technology to record the fine-scale movements of killer whales while simultaneously recording detailed information about the abundance and accessibility of encountered prey. Combining information about killer whale feeding behaviour and their prey will allow us to assess whether SRKWs are prey limited.
