Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant

Seasonal Ice Dynamics Control the Timing of Crevasse Drainage at a Fast‐Flowing Outlet Glacier
Abstract Crevasse field drainage transfers at least half of the seasonal runoff from the surface to the bed of the Greenland Ice Sheet, but the patterns of drainage are complex and spatio‐temporally heterogenous. To better understand controls on crevasse drainage processes, we use an automated deep learning method to map the seasonal filling and ...

Alaska‐Yukon Glacier Depths From a Decade of Airborne Radar Sounding
Abstract NASA's Operation IceBridge employed airborne radar sounders in Alaska and adjacent northwestern Canada between 2012 and 2021 to measure the thickness of the region's glaciers. Here we present the first comprehensive analysis of these data, analyzing ∼31,700 linear‐km of radar profile data to provide over 5,500 linear‐km of ice thickness and ...

Quantifying subglacial roughness and its link to glacial geomorphology and ice speed [PDF]
The shape of subglacial bed topography, termed its roughness, is a recognised control on basal ice-flow. Although glaciologists have observed patterns of variations in ice speed over beds with different roughness values, the strength of this relationship

Radar evidence of ponded subglacial water in Greenland
The thermal state at the bed of a large ice sheet is a critical boundary condition governing its future evolution. Radar surveys provide an opportunity for direct but remote observation of the ice-sheet bed, and therefore offer a means of constraining ...

Abstract Earthflows are landslides in fine‐grained materials that alternate long dormant phases of very slow movement with short paroxysmal stages of rapid motion. These rapid phases are highly destructive, often causing severe damage to buildings and infrastructure.
