Critical Issues on Cold Region Precipitation Characteristics
The type of precipitation to reach the earth's surface is highly dependent on the lower tropospheric temperature profile. Strong and persistent temperature inversions, a unique... -
Development of an Ice-Tethered Winch for the Seasonal Ice Zone
The ice-tethered winch (ITW) will combine the design of two established technologies, the Ice-Tethered Profiler and Arctic Winch. Merging these technologies will expand upon... -
Observing and characterizing submesoscale dynamics in the Arctic Ocean
Preliminary analysis reveals that the Arctic Ocean mixed layer displays a complicated submesoscale structure with significant horizontal density gradients (fronts) and small... -
Continuation of the of Ice-Tethered Profiler contribution to the Arctic Observing Network
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The combined Ice-Based Observatory monitoring program, to which this grant... -
Arctic LTER: Climate Change and Changing Disturbance Regimes in Arctic Landscapes
This award supports the fifth phase of the Long Term Ecological Research Site (LTER) at Toolik Lake, AK. Since 1975, the LTER project and its predecessors have studied landscape... -
Supporting Community Use of the Community Earth System Model for Polar Science
Climate models have consistently indicated that polar regions are among the most sensitive to perturbations in climate forcing. This has been born out in recent years as the... -
Changes in Arctic Sea Ice and their Impact on Timing of Life History and Production of Zooplankton
Nontechnical This project will demonstrate the impact of climate-induced changes in the arctic physical system on the timing of primary production and a single important copepod... -
Ataruq: Connecting Coastal Communities to Polar Research
This project has several interconnected elements that revolve around extending to a wider population existing efforts to improve science literacy in Native Alaskan groups, while... -
Direction and Mechanisms of Seasonal Change in Arctic Microbial Communities
This project focuses on the characteristics and mechanisms of microbial succession in the high Arctic. Empirical observations suggest that seasonal change could be viewed as... -
The Distributed Biological Observatory (DBO)-A Change Detection Array in the Pacific Arctic Region
Several regionally critical marine sites in the Pacific Arctic sector that have very high biological biomass and are focused foraging points for apex predators, have been... -
Quantifying and Predicting the Impact of the Madden-Julian Oscillation on the State of the Arctic
Many authors have documented variability in the state of the Arctic on a range of time scales, including the intraseasonal. Recent studies have noted the dependence of Arctic... -
AON: Observing the Evolving Central Arctic Ocean with Ice-Tethered Profilers
This awards sustains sampling of the upper Arctic Ocean water properties through all seasons using Ice-Tethered Profiler (ITP) instruments. Studies conducted over the last... -
Fire In Northern Alaska: Effect of a Changing Disturbance Regime on a Regional Macrosystem
In northern Alaska, both the climate and the large-area disturbance regime are changing rapidly, as warmer temperatures over the past 50 years are accompanied by more recent... -
AON: Continuing the Beaufort Gyre Observing System to Document and Enhance Understanding Environmental Change in the Arctic
This Arctic Observing Network (AON) project will conduct Beaufort Gyre Observational System (BGOS) operations begun in 2003 do document the unprecedented changes in sea ice and... -
Continuation of Development and Application of AO-FVCOM to Improve Understanding of Arctic Changes
The PIs have successfully developed a high-resolution unstructured-grid, finite volume coupled ice-ocean model for the Arctic Ocean (AO-FVCOM). AO-FVCOM has been validated via... -
Using opportunistic radon measurements to estimate the gas transfer velocity in partial sea ice cover
This project will investigate the use of naturally-occurring radon as a tracer for gas exchange in seasonally ice-covered waters in the Arctic Ocean, using ships of opportunity...
