Episodic Subglacial Drainage Cascades Below the Northeast Greenland Ice Stream
Geophysical Research Letters, 2023 Subglacial hydrology can exert an important control on ice flow by affecting friction at the ice‐bedrock interface. Here, we report on a series of subglacial drainage events along the Northeast Greenland Ice Stream (NEGIS), initiating as far inland as ...

Greenland: Bringing together remote sensing and fieldwork. [PDF]
, 2008 With global land and sea temperatures rising, the importance of accurate monitoring of the world's ice sheets is increasing. Satellite radar altimetry can be used to measure elevation changes of ice sheets from which mass balance can be derived.

Diatomite evidence for a small palaeo mountain lake at 3400 m asl, Lesotho, southern Africa
Journal of Quaternary Science, EarlyView.ABSTRACT The Eastern Lesotho Highlands experience an excess of rainfall sufficient to form the country's primary export, supplying the economic hub of southern Africa, Gauteng South Africa. However, there is currently only one natural lake in the country, Letšeng‐la Letsie, and evidence of palaeolakes in the region is therefore of particular interest ...

J.B. Tyrrell and D.H. Dumble on Lake Ice [PDF]
, 1992 Historically, in Canada, popular and professional interest in river and lake ice were high. In this century, however, there has been a noticeable lack of "formal" interest.

Journal of Quaternary Science, EarlyView.ABSTRACT The Lake Volvi area, part of the region of Macedonia (northern Greece), is a biodiversity hotspot, located in the central part of a major communication corridor connecting the western and eastern parts of the Balkans. The sediment succession from Lake Volvi is investigated here to provide a unique high‐resolution pollen and geochemical record ...

Closing Greenland's Mass Balance: Frontal Ablation of Every Greenlandic Glacier From 2000 to 2020
Geophysical Research Letters, 2023 In Greenland, 87% of the glacierized area terminates in the ocean, but mass lost at the ice‐ocean interface, or frontal ablation, has not yet been fully quantified. Using measurements and models we calculate frontal ablation of Greenland's 213 outlet and

Journal of Quaternary Science, EarlyView.ABSTRACT Water bodies located in floodplains and tropical forests are known to be important carbon stores, but many are subjected to intensive pressures from damming, land use and climate changes. Sedimentary records preserve long‐term archives for understanding how such changes affect the quantity and quality of carbon stores.

Lagrangian formulation, a general relativity analogue, and a symmetry of the Vialov equation of glaciology [PDF]
arXiv, 2020 Using a suitable rescaling of the independent variable, a Lagrangian is found for the nonlinear Vialov equation ruling the longitudinal profiles of glaciers and ice caps in the shallow ice approximation. This leads to a formal analogy between the (rescaled) Vialov equation and the Friedmann equation of relativistic cosmology, which is explored.

Interaction of two tributary glacier branches and implications for surge behavior [PDF]
, 2018 Thesis (M.S.) University of Alaska Fairbanks, 2018A glacier surge is a dynamic phenomenon where the glacier after a long period of quiescence, increases its velocities by up to two orders of magnitude.

Journal of Quaternary Science, EarlyView.ABSTRACT Understanding soil erosion, its history and links to potential drivers such as land use (particularly agriculture and deforestation), different cultural perspectives and climate change are crucial for the development of effective management and conservation strategies.
