Akimiski Island, Nunavut, Canada: The Use of Cree Oral History and Sea-Level Retrodiction to Resolve Aboriginal Title

Autor: Stephen R.J. Tsuji, Jerry X. Mitrovica, Konstantin Latychev, Jorie Clark, E. M. Powell, Leonard J. S. Tsuji, Zachariah General

Publikováno v: ARCTIC. 73:421-432

On 1 April 1999, Akimiski Island of the western James Bay region of northern Ontario, Canada, was included in the newly formed territory of Nunavut, Canada—an Inuit-dominated territory—even though the Inuit had never asserted Aboriginal title to

Viscous Effects in the Solid Earth Response to Modern Antarctic Ice Mass Flux: Implications for Geodetic Studies of WAIS Stability in a Warming World

Autor: E. M. Powell, Natalya Gomez, K. Latychev, Carling C. Hay, Jerry X. Mitrovica

Publikováno v: Journal of Climate. 33:443-459

The West Antarctic Ice Sheet (WAIS) overlies a thin, variable-thickness lithosphere and a shallow upper-mantle region of laterally varying and, in some regions, very low (~1018 Pa s) viscosity. We explore the extent to which viscous effects may affec

Rapid postglacial rebound amplifies global sea level rise following West Antarctic Ice Sheet collapse

Autor: Linda Pan, E. M. Powell, Konstantin Latychev, Jessica R. Creveling, Peter U. Clark, Mark Hoggard, Natalya Gomez, Jerry X. Mitrovica

Publikováno v: Science Advances

Rapid uplift of marine sectors exposed by WAIS collapse amplified GMSL rise in the past and will do so in the future.
Geodetic, seismic, and geological evidence indicates that West Antarctica is underlain by low-viscosity shallow mantle. Thus, a

Reassessing the Contribution of West Antarctica to Last Interglacial Sea Level in Light of 3D Mantle Viscosity Structure

Autor: E. M. Powell, Natalya Gomez, Linda Pan, Mark Hoggard, Konstantin Latychev, Jerry X. Mitrovica, Jessica R. Creveling, Peter U. Clark

Studies of peak global mean sea level (GMSL) during the Last Interglacial (LIG; 130-116 ka) commonly cite values ranging from ~2-5 m for the maximum contribution from grounded, marine-based sectors of the West Antarctic Ice Sheet (WAIS). However, thi

Not a bathtub: A consideration of sea-level physics for archaeological models of human migration

Autor: Jerry X. Mitrovica, Tamara Pico, E. M. Powell, Richard H. Meadow, M. J. Borreggine, Christian A. Tryon

Publikováno v: Journal of Archaeological Science. 137:105507

Accurately reconstructing past sea level is key to simulating potential migration pathways of ancient hominins, including early Homo sapiens. Models of ancient human migration events commonly construct estimates of paleoenvironments using the “bath

Background Nodal staging with sentinel node biopsy (SNB) and completion lymph node dissection (CLND) provides prognostic information to patients with melanoma and their physicians. It is not known whether the timing of CLND is associated with surviva

Sea Level Fingerprints in a Region of Complex Earth Structure: The Case of WAIS

Autor: E. M. Powell, Douglas A. Wiens, Carling C. Hay, Jacqueline Austermann, H. C. P. Lau, Jerry X. Mitrovica, Konstantin Latychev, Natalya Gomez

Publikováno v: Journal of Climate. 30:1881-1892

Sea level fingerprints associated with rapid melting of the West Antarctic Ice Sheet (WAIS) have generally been computed under the assumption of a purely elastic response of the solid Earth. The authors investigate the impact of viscous effects on th

Leveraging the Rapid Retreat of the Amundsen Gulf Ice Stream 13,000 Years Ago to Reveal Insight Into North American Deglaciation

Autor: Tamara Pico, Alexander A. Robel, E. M. Powell, Jerry X. Mitrovica, Alan C. Mix

We examine the influence of different deglacial histories of the North American ice saddle, which connected the Cordilleran ice sheet and western Laurentide ice sheet, on the stability of the fast‐flowing Amundsen Gulf Ice Stream, located in the no
