Radar‐Detected Englacial Debris in the West Antarctic Ice Sheet

recommendations! Published in 2019 at "Geophysical Research Letters"

DOI: 10.1029/2019gl084012

Abstract: Structural glaci‐geological processes can entrain basal sediment into ice, leading to its transportation and deposition downstream. Sediments potentially rich in essential nutrients, like silica and iron, can thus be transferred from continental sources to the… read more here.

DOI: 10.1029/2019gl085281

Abstract: Modeling the early development of the West Antarctic Ice Sheet (WAIS) hinges on the configuration and evolution of Paleogene terrestrial landscapes associated with the West Antarctic Rift System. A widely applied but previously untested paleotopographic… read more here.

DOI: 10.1029/2020gl091835

Abstract: The Southern Ocean plays an important role in the uptake of atmospheric CO2. In seasonally ice‐covered regions, estimates of air‐sea exchange remain uncertain in part because of a lack of observations outside the summer season.… read more here.

recommendations! Published in 2021 at "Journal of Geophysical Research"

DOI: 10.1029/2020jg006227

Abstract: The ocean coastal-shelf-slope ecosystem west of the Antarctic Peninsula (WAP) is a biologically productive region that could potentially act as a large sink of atmospheric carbon dioxide. The durat... read more here.

DOI: 10.1029/2023gl104518

Abstract: Recent observations suggest that El Niño–Southern Oscillation (ENSO) impacts basal melting of West Antarctic ice shelves, yet sparse ocean observations limit our understanding of the associated processes. Here we investigate how ENSO events modulate subsurface… read more here.

DOI: 10.1029/2024gl108933

Abstract: We construct a high‐resolution shear‐wave velocity (VS) model for the uppermost 100 m using ambient noise tomography near the West Antarctic Ice Sheet Divide camp. This is achieved via joint inversion of Rayleigh wave phase… read more here.

recommendations! Published in 2024 at "Nature Communications"

DOI: 10.1038/s41467-024-47369-3

Abstract: Recent geologic and modeled evidence suggests that the grounding line of the Siple Coast of the West Antarctic Ice Sheet (WAIS) retreated hundreds of kilometers beyond its present position in the middle to late Holocene… read more here.

DOI: 10.1038/s41467-025-60772-8

Abstract: Mass loss from polar ice sheets is poorly constrained in estimates of future global sea-level rise. Today, the marine-based West Antarctic Ice Sheet is losing mass at an accelerating rate, most notably in the Thwaites… read more here.

DOI: 10.1038/s41598-021-85042-7

Abstract: It is well established that Antarctic biodiversity has been strongly influenced by rapid climatic fluctuations during the Quaternary. Marine invertebrates from Antarctica constitute an interesting lens through which to study the impacts of the last… read more here.

DOI: 10.1098/rsta.2017.0171

Abstract: Palmer Deep (PD) is one of several regional hotspots of biological productivity along the inner shelf of the West Antarctic Peninsula. The proximity of hotspots to shelf-crossing deep troughs has led to the ‘canyon hypothesis’,… read more here.
