In situ 10Be modeling and terrain analysis constrain subglacial quarrying and abrasion at Jakobshavn Isbræ, Greenland

Publikováno v: eISSN

Glacial erosion creates diagnostic landscapes and vast amounts of sediment. Yet, knowledge about the rate by which glaciers erode and sculpt bedrock and the proportion of quarried (plucked) versus abraded material is limited. To address this, we quan

A Virtual Expedition to the Juneau Icefield

Autor: Allie Balter-Kennedy, Arianna Varuolo-Clarke

The Juneau Icefield Research Program (JIRP) has provided Polar science and research experiences for undergraduates for 75 years, positioning itself as an important pipeline to careers in the Polar sciences and the geosciences at large. With the goal

Greenland ice sheet vulnerability under diverse climatic warming scenarios

Autor: Benjamin Keisling, Joerg Schaefer, Robert DeConto, Jason Briner, Nicolás Young, Caleb Walcott, Gisela Winckler, Allie Balter-Kennedy, Sridhar Anandakrishnan

Sea-level rise of even one meter will have drastic global impacts. Melting the Greenland Ice Sheet (GIS) would raise sea level by 7.4 meters. There is an urgent need to improve predictions of how quickly the GIS will contribute its first meter of sea

10Be analysis in pyroxene - a method for routine chemical extraction

Autor: Allie Balter-Kennedy, Joerg Schaefer, Roseanne Schwartz, Laura Penrose, Jennifer Lamp, Gisela Winckler

We have developed a method for routine processing of pyroxenes for cosmogenic 10Be analyses, offering a multi-nuclide (3He/10Be) approach for mafic terranes. Analyzing multiple cosmogenic nuclides from the same rock/mineral (most commonly, 26Al/10Be

A 14.5-million-year record of East Antarctic Ice Sheet fluctuations from the central Transantarctic Mountains, constrained with cosmogenic 3He, 10Be, 21Ne, and 26Al

Publikováno v: The Cryosphere. 14:2647-2672

The distribution of moraines in the Transantarctic Mountains affords direct constraint of past ice-marginal positions of the East Antarctic Ice Sheet (EAIS). Here, we describe glacial geologic observations and cosmogenic-nuclide exposure ages from Ro

Centennial- and orbital-scale erosion beneath the Greenland Ice Sheet

Autor: Allie Balter-Kennedy, Nicolás Young, Jason Briner, Brandon Graham, Joerg Schaefer

Erosion beneath glaciers and ice sheets is a fundamental Earth-surface process dictating landscape development, which in turn influences ice-flow dynamics and the climate sensitivity of ice masses. The rate at which subglacial erosion takes place, ho
