Atmospheric deposition of glacial iron in the Gulf of Alaska impacted by the position of the Aleutian Low
Our understanding of glacial flour dust storm delivery of iron to the Gulf of Alaska (GoA) is limited. Here we interpret concurrent time series satellite, meteorological, and aerosol geochemical data from the GoA to examine how interannual variability in regional weather patterns impacts offshore aerosol glacial Fe deposition. In 2011, when a...
Schroth, Andrew W.; Crusius, John; Gasso, Santiago; Moy, Christopher M.; Buck, Nathan J.; Resing, Joseph A.; Campbell, Robert W. Declining survival of black brant from subarctic and arctic breeding areas
Since the mid 1990s, the number of black brant (Branta bernicla nigricans; brant) nests on the Yukon‐Kuskokwim Delta (YKD), Alaska, USA, the historically predominant breeding area of brant, has declined steadily. This has caused researchers and managers to question if arctic breeding populations can compensate for the reduction in brant nests on...
Leach, Alan G.; Ward, David H.; Sedinger, James S.; Lindberg, Mark S.; Boyd, W. Sean; Hupp, Jerry W.; Ritchie, Robert J. Population genetic structure and gene flow of Adélie penguins (Pygoscelis adeliae) breeding throughout the western Antarctic Peninsula
Adélie penguins (Pygoscelis adeliae) are responding to ocean–climate variability throughout the marine ecosystem of the western Antarctic Peninsula (WAP) where some breeding colonies have declined by 80%. Nuclear and mitochondrial DNA (mtDNA) markers were used to understand historical population genetic structure and gene flow given relatively...
Gorman, Kristen B.; Talbot, Sandra L.; Sonsthagen, Sarah A.; Sage, George K.; Gravley, Megan C.; Fraser, William R.; Williams, Tony D. Status of natural and human environments: Chapter 3
This report present the results of the 2017 AMAP Assessment of Adaptation Actions for a changing Arctic (AACA): Perspectives form the Bering-Chukchi-Beaufort Region. This is one of three pilot study regions included in the AACA project. AACA is the first AMAP assessment dealing with adaptation actions and how to meet possible Arctic futures in...

Streambed scour evaluations and conditions at selected bridge sites in Alaska, 2013–15
Streambed scour potential was evaluated at 52 river- and stream-spanning bridges in Alaska that lack a quantitative scour analysis or have unknown foundation details. All sites were evaluated for stream stability and long-term scour potential. Contraction scour and abutment scour were calculated for 52 bridges, and pier scour was calculated for 11...

Lithium
Lithium, the lightest of all metals, is used in air treatment, batteries, ceramics, glass, metallurgy, pharmaceuticals, and polymers. Rechargeable lithium-ion batteries are particularly important in efforts to reduce global warming because they make it possible to power cars and trucks from renewable sources of energy (for example, hydroelectric,...

Zirconium and hafnium
Zirconium and hafnium are corrosion-resistant metals that are widely used in the chemical and nuclear industries. Most zirconium is consumed in the form of the main ore mineral zircon (ZrSiO4, or as zirconium oxide or other zirconium chemicals. Zirconium and hafnium are both refractory lithophile elements that have nearly identical charge, ionic...
Schulz, Klaus J.; DeYoung,, John H.; Seal, Robert R. ; Bradley, Dwight C.; Jones, James V.; Piatak, Nadine M.; Bedinger, George M. Evaluating methods to assess the body condition of female polar bears
An animal's body condition provides insight into its health, foraging success, and overall fitness. Measures of body composition including proportional fat content are useful indicators of condition. Isotopic dilution is a reliable non-destructive method for estimating the body composition of live mammals, but can require prolonged handling times...
Pagano, Anthony M.; Rode, Karyn D.; Atkinson, Stephen N. Tectonic evolution of the Central Andean Plateau and implications for the growth of plateaus
Current end-member models for the geodynamic evolution of orogenic plateaus predict (a) slow and steady rise during crustal shortening and ablative subduction (i.e., continuous removal) of the lower lithosphere or (b) rapid surface uplift following shortening, which is associated with punctuated removal of dense lower lithosphere and/or lower...

Attaching transmitters to waterbirds using one versus two subcutaneous anchors: Retention and survival trade-offs
A major challenge of wildlife telemetry is choosing an attachment technique that maximizes transmitter retention while minimizing negative side effects. For waterbirds, attachment of transmitters with subcutaneous anchors has been an effective and well-established technique, having been used on >40 species. This method was recently modified to...
Lewis, Tyler; Esler, Daniel N.; Uher-Koch, Brian D.; Dickson, Rian D.; Anderson, Eric M.; Evenson, Joseph R.; Hupp, Jerry W.; Flint, Paul L. Forecasting consequences of changing sea ice availability for Pacific walruses
The accelerating rate of anthropogenic alteration and disturbance of environments has increased the need for forecasting effects of environmental change on fish and wildlife populations. Models linking projections of environmental change with behavioral responses and bioenergetic effects can provide a basis for these forecasts. There is particular...
Udevitz, Mark S.; Jay, Chadwick V.; Taylor, Rebecca L.; Fischbach, Anthony S.; Beatty, William S.; Noren, Shawn R. Genetic implications of bottleneck effects of differing severities on genetic diversity in naturally recovering populations: An example from Hawaiian coot and Hawaiian gallinule
The evolutionary trajectory of populations through time is influenced by the interplay of forces (biological, evolutionary, and anthropogenic) acting on the standing genetic variation. We used microsatellite and mitochondrial loci to examine the influence of population declines, of varying severity, on genetic diversity within two Hawaiian endemic...

Landslide Spreads 6 Miles Across Glacier Bay National Park
On June 28, 2016, a 4,000-foot-high mountainside in Glacier Bay National Park and Preserve collapsed, sending rocky debris equivalent to 60 million mid-size SUVs tumbling onto nearby Lamplugh Glacier. Almost 6 weeks later, on August 7, the Operational Land Imager sensor aboard Landsat 8 captured the black stain of the landslide in the image on the right. No such

China and Indonesia suffered the deadliest and most destructive earthquakes in 1996, while the U.S. remained relatively quiet according to scientists at the U.S. Geological Survey, Department of the Interior. The last deadly earthquake in the U.S. was the 1994 Northridge, Calif., quake that took 60 lives.

From glaciers and lava flats to white spruce woodlands and bog communities, a new U.S. Geological Survey report will aid scientists, managers and planners in organizing environmental data.
A magnitude 6.4 earthquake occurred Thurs., Oct. 5, 1995, in Alaska, about 40 miles northwest of Fairbanks, at 9:23 p.m. Alaska Daylight Time (1:23 a.m. EDT, Oct. 6), according to the U.S. Geological Survey.
"After seven months of near-stagnation, Alaska’s Bering Glacier resumed surging. Between May 19th and June 1, part of the glacier advanced almost half a mile (about 2,500 ft). As of mid-September, the surge was continuing," said Bruce F. Molnia, leader of the U.S. Geological Survey’s Bering Glacier Research Project.
