Large-eddy simulations of the ice-shelf–ocean boundary layer near the ice front of Nansen Ice Shelf, Antarctica [PDF]
The Cryosphere, 2022 Ice melting beneath Antarctic ice shelves is caused by heat transfer through the ice-shelf–ocean boundary layer (IOBL). However, our understanding of the fluid dynamics and thermohaline physics of the IOBL flow is poor.

The Geo-educational and Conservational Challenges Posed by Unconsolidated Deposits: Some Thoughts and Possible Solutions as Applied to Diamicton Deposits from the British Isles [PDF]
Geoconservation Research, 2022 Unconsolidated diamicton deposits of Quaternary age cover much of the lowland areas of the British Isles. These are often poorly exposed and as a result their influence on development and importance as palaeontological archives are often under ...

Arctic deep-water anoxia and its potential role for ocean carbon sink during glacial periods
Communications Earth & Environment, 2023 Freshening and oxygen depletion of the polar deep waters of the Amerasian Basin during the last glacial periods probably resulted in significant carbon burial, according to geochemical analyses of inorganic authigenic carbonates in Arctic Ocean sediments.

Seasonality of isotopic and chemical composition of snowpack in the vicinity of Jang Bogo Station, East Antarctica [PDF]
Polish Polar Research, 2021 Seasonal variations of the isotopic and chemical compositions of snowpits can provide useful tools for dating the age of the snowpit and examining the sources of aerosol.

Sensitivity of the Tropical Dust Cycle to Glacial Abrupt Climate Changes
Geophysical Research Letters, 2023 During abrupt climate changes of the last glacial period paleorecords show large amplitude changes in the dust cycle. We use Earth System model simulations to evaluate processes operating across these events.

Ice Shelf Water Structure Beneath the Larsen C Ice Shelf in Antarctica
Geophysical Research Letters, 2023 Understanding ice shelf water (ISW) structure is crucial for studying the basal melting of ice shelves. In this study, we performed large‐eddy simulation experiments to assess ISW structure and basal melt patterns under different current velocity ...

The Late Palaeozoic Ice Age unconformity in southern Namibia viewed as a patchwork mosaic
The Depositional Record, 2022 The expansion of ice masses across southern Africa during the Late Palaeozoic Ice Age has been known for 150 years, including the distribution of upland areas in controlling the configuration of glaciation.

Widespread erosion on high plateaus during recent glaciations in Scandinavia [PDF]
, 2018 Glaciers create some of Earth’s steepest topography; yet, many areas that were repeatedly overridden by ice sheets in the last few million years include extensive plateaus.

Sea surface temperature changes in the southern California borderlands during the last glacial-interglacial cycle [PDF]
, 1996 A variety of evidence suggests that average sea surface temperatures (SSTs) during the last glacial maximum in the California Borderlands region were significantly colder than during the Holocene.
