Emergence of the Shackleton Range from beneath the Antarctic Ice Sheet due to glacial erosion [PDF]

, 2014
This paper explores the long-term evolution of a subglacial fjord landscape in the Shackleton Range, Antarctica. We propose that prolonged ice-sheet erosion across a passive continental margin caused troughs to deepen and lower the surrounding ice-sheet ...

The glacial geomorphology of the Mackenzie Mountains region, Canada

Journal of Maps, 2023
During the Last Glacial Maximum, the Mackenzie Mountains region was glaciated by three distinct ice sources; the Laurentide Ice Sheet, the Cordilleran Ice Sheet, and independent montane glaciers. Rapid ice sheet thinning of the Laurentide-Cordilleran ice

Submarine geomorphology of the northeastern Baffin Island fiords and cross-shelf troughs

Journal of Maps, 2019
This paper presents a series of 50 geomorphological maps of the seabed of northeastern Baffin Island fiords and cross-shelf troughs, in eastern Arctic Canada. The mapping was produced using swath bathymetry imagery from multiple bathymetry datasets.

A Contribution to the Young-Quaternary Geomorphology in the Upper Sava

Acta Geographica Slovenica, 1992
To the older and younger Pleistocene glacier in the valley of the upper Sava (between the Mts Julian Alps and Karavanke, in contact zone of the states Slovenia, Italy and Austria) ice masses from the Gailtal valley slided through the straits at Tarvisio

Glacial geomorphological characterization and glacigenic sedimentation in Admiralty Bay, Maritime Antarctica

Revista Brasileira de Geomorfologia
The study of the relationship between geomorphology and sedimentation processes is important as it clarifies information about relict landscapes. These processes are understood based on glacial landforms and the characteristics of their sediments.

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...
