Sea-ice thickness measurement off Barrow

Alaska Ocean Observing System (AOOS) - At two locations off Barrow, ice thickness and velocity are measured along with water velocity profile, temperature and salinity. The nearshore site is within the footprint of the UAF sea-ice radar in Barrow. The offshore site is within a frequently occurring coastal polynya and its data will be used to validate estimate of thin ice thickness from satellite microwave sensor.

Arctic Change

National Oceanic and Atmospheric Administration (NOAA) - The objective of this website is to present recent indicators that describe the present state of the Arctic climate and ecosystem in an accessible, understandable, and credible historical context. A summary of changes are listed in the Table of Indicators. The Arctic is a vast, ice-covered ocean that is surrounded by tree-less, frozen land, which is often covered with snow and ice. The...

The Effect of Sea Ice Mobility on Shelf Basin Exchange in the Alaskan Beaufort Sea

North Pacific Research Board (NPRB) - The Alaskan Beaufort shelf (ABS) is fed by Pacific water emanating from Bering Strait and is strongly wind-forced in fall and winter due to the passage of synoptic storms. Because this Pacific derived water flowing along the northern boundary of the ABS is nutrient rich, upwelling of these Pacific waters onto the ABS is an important source of nutrients to the shelf. Thus understanding upwelling...

A tale of two polar bear populations: ice habitat, harvest, and body condition

US Fish and Wildlife Service (USFWS) - One of the primary mechanisms by which sea ice loss is expected to affect polar bears is via reduced body condition and growth resulting from reduced access to prey. To date, negative effects of sea ice loss have been documented for two of 19 recognized populations. Effects of sea ice loss on other polar bear populations that differ in harvest rate, population density, and/or feeding ecology...

Collaborative Research: Thermodynamic and Dynamic Drivers of the Arctic Sea Ice Mass Budget at MOSAiC

Oregon State (ORSTATE) - Energy fluxes to the sea ice, and the processes that control them in time and space, comprise some of the largest uncertainties in current models of the central Arctic system and are likely changing as the sea ice thins. This project will make observations to provide the type of information that model developers need for representing emergent Arctic processes. These observations will be the...

Changing Arctic Ecosystems: Enhancing forecasts of polar bear and walrus population response to a rapidly changing Arctic ecosystem (Onshore polar bears)

US Geological Survey (USGS) - A new and major piece of our current research program is targeted at polar bears summering on land in Alaska. This is a new behavior, and current estimates suggest that during recent minimums of sea ice extent up to 10% of the Southern Beaufort (SB) sea population has remained on land rather than following sea ice into the deep polar basin. The focus of this work is to examine demographic,...

Fate of Dispersed Oil under Ice

International Association of Oil and Gas Producers (IAOGP) - Dispersion of oil using either chemical or mineral additives (dispersants) can be an effective way to enhance the natural biodegradation process to remove spilled oil from the marine environment. Research over several decades has shown that these additives can be as effective in near-freezing waters as they are in temperate waters when properly applied. The use of dispersants can provide an...

Toward a Predictive Model of Arctic Coastal Retreat in a Warming Climate, Beaufort Sea Alaska

US Bureau of Ocean Energy Management (BOEM) - The long-term goal of this project is to quantify the environmental drivers of extremely rapid coastal erosion in the Arctic, and to begin developing predictive models of future rates of coastal erosion resulting from climate change. Our study is focused on the Beaufort Sea coast within the National Petroleum Reserve – Alaska (NPR-A), approximately halfway between Barrow and Prudhoe Bay. ...

Survival and breeding of polar bears in the southern Beaufort Sea in relation to sea ice

US Geological Survey (USGS) - 1. Observed and predicted declines in Arctic sea ice have raised concerns about marine mammals. In May 2008, the US Fish and Wildlife Service listed polar bears (Ursus maritimus) – one of the most ice-dependent marine mammals – as threatened under the US Endangered Species Act. 2. We evaluated the effects of sea ice conditions on vital rates (survival and breeding probabilities) for polar...

Changing Arctic Ecosystems: Enhancing forecasts of polar bear and walrus population response to a rapidly changing Arctic ecosystem (Modeling walrus-habitat associations and foraging energetics)

US Geological Survey (USGS) - The loss of sea ice during summer over the continental shelf of the Chukchi Sea in recent years has had visible effects on walrus distribution and behavior. The use of land haulouts by female and young walruses in the absence of offshore sea ice in recent years has resulted in direct calf mortality and almost certainly affects the availability of prey to walruses and, consequently, foraging...

Arctic Report Card

National Oceanic and Atmospheric Administration (NOAA) - The Arctic Report Card (www.arctic.noaa.gov/reportcard/) considers a wide range of environmental observations throughout the Arctic, and is updated annually. A major conclusion of the 2011 Report is that there are now a sufficient number of years of data to indicate a shift in the Arctic Ocean system since 2006. This shifted is characterized by the persistent decline in the thickness and summer...

Mechanical Recovery of Oil in Ice

International Association of Oil and Gas Producers (IAOGP) - Mechanical containment and recovery is considered the primary or preferred response strategy in many regions of the world. Containment booms are normally used in combination with a skimmer to remove oil from the water’s surface where it is temporarily stored before further treatment. The main challenge presented to mechanical recovery in ice is the difficulty of accessing the oil and,...

Oil Spill Trajectory Modelling in Ice

International Association of Oil and Gas Producers (IAOGP) - An oil spill trajectory model predicts the movement of spilled oil in and under ice, based on such factors as ocean currents, winds, and air and sea temperatures. In Arctic conditions, the predictive task is complicated by the presence of ice in a variety of forms. Furthermore, little information exists about Arctic currents and there are few opportunities to evaluate the predictive accuracy of...

Changing Arctic Ecosystems: Enhancing forecasts of polar bear and walrus population response to a rapidly changing Arctic ecosystem (New methods to estimate demographic parameters of walruses)

US Geological Survey (USGS) - Nothing is known about the demographic rates of walrus, much less potential changes in these demographic rates caused by changing sea ice conditions due to climate change. Direct measures of walrus reproductive rates are extremely difficult to obtain due to the remote location of walrus calving habitats. Cow-calf ratios could be a useful index of walrus reproductive performance, but these are...
