In general, my primary research interests are focused on research of the Arctic climate system and climate change through investigation of the Arctic Ocean Oscillation (AOO) and its interaction with the North Atlantic Oscillation (NAO) and the North Pacific Oscillation (PAO). I have been examining the climate variability and interactions between environmental parameters and processes in the Arctic through the use of combination of field work, statistical analyses of results, and numerical models. Physical oceanography and polar meteorology, arctic climatology, sea ice studies, tides and storm surges are subjects of my research.
Current Research Projects
- regional oceanography of the arctic seas
- Investigating Two Regimes of Arctic System Variability (NSF)
The main goal of the project is to identify decadal scale signals in the Arctic's atmospheric and oceanic systems to understand the major processes maintaining the observed long-period variations. Our recent work demonstrates that there are two regimes of ice-ocean circulation, each of four to six years duration. The research centers around determining how this decadal variability is maintained. We ask the principal question: Is the Arctic system self-regulated or driven by external forces? The process of answering this question will help us understand how the Arctic influences and is influenced by global change, and help us understand the role of the two regimes of circulation in maintaining the system's natural variability.
- Large-Scale Ice and Oceanographic Changes in the Bering Sea During the Last 50 years (NOAA/Pacific Oceanographic Institute, Vladivostok,)
The primary goal of this proposal is to identify large-scale multi-year ice and oceanographic changes in the Bering Sea and determine the major factors that maintain them. 2-D and 3-D coupled ice-ocean models are utilized to examine oceanic circulation patterns and ice motion in response to atmospheric and oceanic forcing. Oceanic and meteorological data sets collected over the last 50 years are analyzed to determine observed variability of environmental conditions.
- Wind Field Representations and Their Effect on Shelf Circulation Models: A Case Study in the Chukchi Sea (Coastal Marine Institute)
Arctic pollutant transport models use forcing by winds estimated from atmospheric forecasts of the surface pressure fields. There are uncertainties in these forecasts pressure fields which lead to errors in the circulation models dependent upon this information. It is proposed to examine the differences in shelf circulation as predicted by 2-D and 3-D model when forced by 3 wind fields (from European Center for Medium Weather Range Forecasting, US Navy's Fleet Numerical Oceanography Center and used by Rutgers University to drive their circulation model.
