Kelly Falkner
(oceanography)
Arctic Ocean variability: By tracing water chemistry from the North Pole to the Canadian Archipelago and Nares Strait, Kelly Falkner is learning how changes in rivers and ocean circulation are related to climate effects.

Ed Brook
(geosciences)
Ice core studies: In ice cores from Greenland and Antarctica, Ed Brook is finding historical records of millennial-scale abrupt climate change. He is also analyzing ancient air from old ice outcroppings for clues to climate change mechanisms in recent geologic time.

Jesse Ford
(fisheries and wildlife)
Arctic contaminants: By studying the pan-Arctic distribution of contaminants in fish and vegetation, Jesse Ford is trying to understand the distribution and drivers of Arctic “hot spots” of heavy metals and persistent organic pollutants.

Alan Mix
(oceanography)
Alaska fjord survey: By surveying seafloor surfaces and recovering sediment cores from Alaska fjords and the Gulf of Alaska, Alan Mix is compiling data on past climate variability that extends the historical record.

Peter Clark
(geosciences)
Dating glacial moraines: Using new isotopic dating techniques on glacial moraines in Labrador, Peter Clark is gathering clues to the timing and dynamics of the last period of deglaciation — and seeking processes of change during a warming climate.

Anne Nolin
(geosciences)
Ice-sheet mapping: Sophisticated new sensing techniques devised by Anne Nolin have led to more accurate mapping of ice-sheet albedo (reflectivity), ice-sheet roughness, and snow-covered locations with vegetation cover — key factors in monitoring climate change.

Staci Simonich
(environmental toxicology/chemistry)
High-elevation contaminants: By tracing airborne contaminants through high-elevation National Park ecosystems, Staci Simonich is shedding light on how pollutants move from atmosphere to snow, vegetation, lake water, fish, and sediment.

Andrew Meigs
(geosciences)
Glacial erosion rates: Andrew Meigs’ studies of erosion and mountain-range growth in Alaska suggest that erosion rates are linked to climate change and glaciation.

David Graham
(oceanography)
Arctic Ocean geochemistry: On expeditions to map the seafloor and collect water samples in the high Arctic and North Pole, David Graham has discovered important clues to the tectonic history of the region.

Nick Pisias
(oceanography)
Regional climate change: By examining historical climate shifts with advanced statistical methods, Nick Pisias is trying to understand links between climate variability in the low-latitude oceans and effects seen in the Arctic.

Fred Prahl
(oceanography)
Organic biomarkers: By decoding the composition of organic molecules in marine sediments off Alaska, Fred Prahl is tracing the inputs of carbon from land to the ocean and developing organic tracers of climate change.

Andreas Schmittner
(oceanography)
Modeling ocean currents and biology: Using advanced computer models of the ocean and atmosphere, coupled to chemical and biological effects, Andreas Schmittner is examining global impacts of melting Arctic ice and greenhouse warming of the polar oceans.

Joseph Stoner
(marine geology and geophysics)
Paleomagnetism: Measuring the magnetism observed in Arctic marine and lake sediments, Joseph Stoner has turned up evidence of rapid shifts in Earth’s magnetic field.

Marta Torres
(oceanography)
Clam shells and climate change: By measuring the isotopic chemistry of long-lived clam shells, Marta Torres is documenting long-term changes in Arctic Ocean salinity related to climate.

Timothy Boyd
(oceanography)
Arctic Ocean monitoring: Collecting data on variations in circulation, heat and salt content — both historical and contemporary — Timothy Boyd has documented significant changes under way in the Arctic.

Evelyn Sherr, Barry Sherr & Yvette Spitz
(oceanography)
Subsistence whaling: Evelyn Sherr, Barry Sherr and Yvette Spitz are investigating native communities’ resilience to climate variability. Their research focuses on interactions among atmosphere, sea ice, ocean, bowhead whales and subsistence whaling.
