Theresa Venello is a Biological Oceanographer specializing in pelagic marine ecosystem responses to climate change. Her work prior to joining Applied Marine Sciences (AMS) included investigating planktonic crustacean physiological responses to ocean acidification in Polar regions as well as zooplankton community responses to the 2015 Marine Heatwave event in the NE Pacific known as “The Blob”. Theresa also used a functional assessment approach to examine changes in ecological roles of zooplankton species over a 30-year time frame. She has extensive fieldwork experience, logging 120+ days at sea from 2015-2018 working closely with Fisheries and Oceans Canada on their North Pacific Oceanographic and Zooplankton Monitoring Programs. Additionally, Theresa has worked on coastal survey projects looking at predator-prey dynamics between gray whales and plankton prey as well as Atlantic Harbor seals and seasonal fish species. Theresa is proficient in R, as well as time series and multivariate statistical analysis. She has 4 publications in respected marine science journals and has presented her research at international scientific conferences. Theresa earned a Ph.D. in Biological Oceanography from the University of Victoria, a M.Res. in Marine Biology from the University of Plymouth and a B.S. in Marine Science from Stockton University.
