Research Overview

Dr. Pinchuk has been studying marine zooplankton both in the field and laboratory/aquarium settings for almost 20 years. His research has been focused on zooplankton distribution and production in relation to physical properties of the environment as well as their role in the pelagic trophic structure. His experiences have extended into the Russian Far East, Arctic and North Pacific. Earning a Ph.D. in oceanography at the University of Alaska Fairbanks, Dr. Pinchuk has been combining field and laboratory approaches to study interannual and seasonal variability in distribution, growth and reproduction of euphausiids (krill) from the northern Gulf of Alaska as part of US GLOBEC monitoring program. Since he started working for the ASLC in 2006, Dr. Pinchuk has been involved with testing state-of-the-art marine sensors as part of Alliance of Coastal Technologies (ACT), a NOAA funded project. Other research includes a number of collaborative oceanographic projects in the southeastern Bering Sea and northern Gulf of Alaska, studying various aspects of zooplankton ecology in relation to physical and biological variability in the system at variety of temporal and spatial scales.
