Analysis of a GRACE global mascon solution for Gulf of Alaska glaciers

Creator:: Arendt, Anthony, Luthcke, Scott, Gardner, Alex, O'Neel, Shad, Hill, David, Moholdt, Geir, and Abdalati, Waleed
Abstract:: We present a high-resolution Gravity Recovery and Climate Experiment (GRACE) mascon solution for Gulf of Alaska (GOA) glaciers and compare this with in situ glaciological, climate and other remote-sensing observations. Our GRACE solution yields a GOA glacier mass balance of -65 ± 11 Gta⁻¹ for the period December 2003 to...

High-resolution modeling of coastal freshwater discharge and glacier mass balance in the Gulf of Alaska watershed

Creator:: Beamer, J. P., Hill, D. F., Arendt, A., and Liston, G. E.
Abstract:: A comprehensive study of the Gulf of Alaska (GOA) drainage basin was carried out to improve understanding of the coastal freshwater discharge (FWD) and glacier volume loss (GVL). Hydrologic processes during the period 1980–2014 were modeled using a suite of physically based, spatially distributed weather, energy-balance snow/ice melt, soil water...

Regional Scale Modeling of Climate, Cryosphere, and Freshwater Discharge in Changing Coastal Mountain Environments

Creator:: Beamer, Jordan P.
Abstract:: The glaciated coastal mountain watersheds that drain into the Gulf of Alaska (GOA) provide a model laboratory to explore the challenges of hydrological modeling and study the impact of climate and glacier cover change on regional hydrology. The region is data-sparse and contains a complex assemblage of topography and land...

Preconditioning of the 2007 sea-ice melt in the eastern Beaufort Sea, Arctic Ocean

Creator:: Hutchings, Jennifer K. and Perovich, Donald K.
Abstract:: During summer 2007, perennial sea ice in the Beaufort Sea, Arctic Ocean, experienced an unprecedented amount of basal melt. It has previously been shown that this basal melt was linked to an increase in open-water fraction, increasing absorption of solar radiation into the ocean. GPS ice drifters, deployed around the...

On sea-ice dynamical regimes in the Arctic Ocean

Creator:: Lukovich, J. V., Hutchings, J. K., and Barber, D. G.
Abstract:: Central to an understanding of evolution in sea-ice characteristics in response to climate change is an understanding of sea-ice dynamics. In this study, we investigate regional differences in ice dynamics in the Beaufort Sea and High Arctic using high-frequency ice buoy (beacon) data deployed during the SEDNA and IPY-CFL field...

Present-day and future contributions of glacier runoff to summertime flows in a Pacific Northwest watershed: Implications for water resources

Creator:: Nolin, Anne W., Phillippe, Jeff, Jefferson, Anne, and Lewis, Sarah L.
Abstract:: While the impacts of long-term climate change trends on glacier hydrology have received much attention, little has been done to quantify direct glacier runoff contributions to streamflow. This paper presents an approach for determining glacier runoff contributions to streamflow and estimating the effects of increased temperature and decreased glacier area...

Carbon monoxide as a tracer of gas transport in snow and other natural porous media

Creator:: Huwald, Hendrik, Selker, John S., Tyler, Scott W., Calaf, Marc, van de Giesen, Nick C., and Parlange, Marc B.
Abstract:: The movement of air in natural porous media is complex and challenging to measure. Yet gas transport has important implications, for instance, for the evolution of the seasonal snow cover and for water vapor transport in soil. A novel in situ multi-sensor measurement system providing high-resolution observation of gas transport...

Abrupt change in atmospheric CO₂ during the last ice age

Creator:: Ahn, Jinho, Brook, Edward J., Schmittner, Andreas, and Kreutz, Karl
Abstract:: During the last glacial period atmospheric carbon dioxide and temperature in Antarctica varied in a similar fashion on millennial time scales, but previous work indicates that these changes were gradual. In a detailed analysis of one event we now find that approximately half of the CO₂ increase that occurred during...

Ice Cores from the St. Elias Mountains, Yukon, Canada: Their Significance for Climate, Atmospheric Composition and Volcanism in the North Pacific Region

Creator:: Zdanowicz, Christian, Fisher, David, Bourgeois, Jocelyne, Yalcin, Demuth, Mike, Zheng, James, Mayweski, Paul, Kreutz, Karl, Osterberg, ERich, Yalcin, Kaplan, Wake, Cameron, Steig, Eric J., Froese, Duane, and Goto-Azuma, Kumiko
Abstract:: A major achievement in research supported by the Kluane Lake Research Station was the recovery, in 2001–02, of a suite of cores from the icefields of the central St. Elias Mountains, Yukon, by teams of researchers from Canada, the United States, and Japan. This project led to the development of...

Comparing methods of measuring sea-ice density in the East Antarctic

Creator:: Hutchings, Jennifer K., Heil, Petra, Lecomte, Oliver, Stevens, Roger, Steer, Adam, and Lieser, Jan L.
Abstract:: Remotely sensed derivation of sea-ice thickness requires sea·ice density. Sea-ice density was estimated with three techniques during the second Sea Ice Physics and Ecosystem eXperiment (SIPEX-II, September-November 2012, East Antarctica). The sea ice was first-year highly deformed, mean thickness 1.2 m with layers, consistent with rafting, and 6-7/10 columnar ice...
