Insights into glacial processes from micromorphology of silt-sized sediment
Autor: A. P. Lepp, L. E. Miller, J. B. Anderson, M. O'Regan, M. C. M. Winsborrow, J. A. Smith, C.-D. Hillenbrand, J. S. Wellner, L. O. Prothro, E. A. Podolskiy

Silt-rich meltwater plume deposits (MPDs) analyzed from marine sediment cores have elucidated relationships that are clearly connected, yet difficult to constrain, between subglacial hydrology, ice-marginal landforms, and grounding-zone retreat patte

Characteristics of the deforming bed: till properties on the deglaciated Antarctic continental shelf
Autor: John B. Anderson, Anna Ruth W. Halberstadt, L. O. Prothro, Philip J. Bart, Lauren M. Simkins
Publikováno v: Journal of Glaciology. 64:1014-1027
Contemporary ice stream flow is directly linked to conditions at the ice/bed interface, yet this environment is logistically difficult to access. Instead, we investigate subglacial processes important for ice stream flow by studying tills on the degl

Glacial retreat patterns and processes determined from integrated sedimentology and geomorphology records
Autor: Lauren M. Simkins, L. O. Prothro, Wojciech Majewski, John B. Anderson
Publikováno v: Marine Geology. 395:104-119
Although hundreds of cores have been collected on the Antarctic continental shelf over the past five decades, definitive interpretations of depositional environments associated with marine-based ice advance and retreat are hindered by similarities in

Anatomy of a meltwater drainage system beneath the ancestral East Antarctic ice sheet
Autor: Sarah L. Greenwood, Leigh A. Stearns, Helge M. Gonnermann, John B. Anderson, L. O. Prothro, Lauren M. Simkins, David Pollard, Robert M. DeConto, Anna Ruth W. Halberstadt
Publikováno v: Nature Geoscience. 10:691-697
The East Antarctic ice sheet was larger than present during past cold periods. Seafloor geophysical data show that in the Ross Sea, the extended ice sheet was underlain by an active hydrologic system during the glacial termination.

Timing and pathways of East Antarctic Ice Sheet retreat
Autor: Naohiko Ohkouchi, Masako Yamane, Wojciech Majewski, Yosuke Miyairi, John B. Anderson, Yusuke Yokoyama, L. O. Prothro, Lauren M. Simkins
Publikováno v: Quaternary Science Reviews. 230:106166
A lack of reliable chronology often leaves Antarctic ice sheet reconstructions incomplete. Despite being the most heavily investigated region of the Antarctic continental shelf, the post-Last Glacial Maximum (LGM) record of marine-based ice sheet dyn
