Weather extremes in the present and projected future climate, Arctic freshwater and sea ice and their roles in global climate, development of climate model and improvement of physical treatments.

Dr. William Pearcy is a world-renowned authority on many aspects of biological oceanography, in particular his extensive work on fishes and squids in the North Pacific. He has made significant contributions to many areas of marine research, including fisheries oceanography, the ecology of deep-sea and open ocean fishes and squids, the trophic dynamics of marine fishes, and pollution and trace metals in the marine environment. He is perhaps best known recently for his contributions to understanding all aspects of Northeast Pacific salmon during their ocean phase.

The research program of my group is broadly defined by the ecology of aquatic communities, currently ranging from amphibian populations of California, the Pacific Northwest, and the far north, to the river and lake food webs that support salmon populations from California to Alaska. We rely heavily on field-based experimental manipulations to tease apart the mechanistic underpinnings of ecological patterns, from species physiology to food web interactions.

My area of expertise is climate dynamics with emphasis on feedbacks affecting polar amplification (PA) of global warming. These feedbacks are unrelated to the so-called "local" polar amplification mechanisms associated with surface albedo and clouds. They are linked to remote signal propagating to the Arctic atmosphere from the lower latitudes as the climate warms.

Examining feedbacks between environmental change and human behavior. Developing community-based indicators for measuring the social and environmental conditions. Characterizing the relationship between urban development patterns and environmental quality.

He has broad interests in hydrology, climate dynamics, water resource systems analysis, risk management and sustainability.

Dr. Hollmen's research focuses on the physiology and health of wild avian species, especially waterfowl and marine birds, development of methods and biomarkers to evaluate body condition, immune function and disease/contaminant effects in birds, and application of such techniques for monitoring of population health and fitness of wild birds.

Physical oceanography of Alaskan continental shelves and slopes, interdisciplinary marine research, and wind and buoyancy-forced shelf circulation systems.

Tom Miewald is a Geographer with the US Fish and Wildlife Service and specializes in mapping and modeling spatial aspects of wildlife for applied conservation planning problems. Currently, Mr. Miewalds' focus is on providing decision support for the wildlife refuge system across multiple spatial scales. Prior to working for the USFWS, Tom was the Conservation Planner for the Wild Salmon Center, helping to prioritize salmon conservation actions internationally. Tom has also been a Project Manager and Lead Analyst for several large federal vegetation and land cover mapping projects, including the USGS GAP program, NOAA Coastal Change Analysis Program, and the USGS National Land Cover Dataset.

My research focuses broadly on how climate, vegetation, and human activities influence hydrological processes from the point to the small watershed scale. Specific research topics focus on how vegetation affects snowpack and related ecological processes, how climate changes will be manifested in the rain-snow transition zone in complex terrain, and how forest management activities affect water flow, quality, and riparian systems

My research encompasses a wide variety of biological disciplines, including aquatic, behavioral and community ecology, invasion biology, conservation biology, and herpetology. I typically work in freshwater habitats and address ecologically based questions using amphibian and invertebrate systems. I have projects quantifying predator/prey dynamics, competition regimes, stressor defense strategies, and microhabitat preference using observational, theoretical and empirical methods.

My major areas of research are population dynamics of endangered plants and invasive species. Matrix models can be used to pose "what if" questions to develop hypotheses for a population's response to various changes in its environment, such as decreased seed predation, grazing, reproductive failure, global warming, or even wild harvest.

Marine chemistry/chemical oceanography, nutrient chemistry, nitrogen cycle, biogeochemical processes, dynamics of coastal ocean and estuaries, eutrophication and oxygen depletion, nutrient uptake and regeneration, and harmful algal bloom.

Forest measurements and biometrics, modeling, and LiDAR. My research focuses on three major areas and seeks to develop (or extend): 1) imputation methods that support dynamic forest inventory, silvicultural planning, and habitat analysis; 2) sampling and statistical methods to characterize and quantify status and change of selected attributes including biomass and carbon and 3) Applications of lidar to forest measurements and assessments.
