Subglacial meltwater routes of the Fennoscandian Ice Sheet

Journal of Maps, 2022
Subglacial drainage systems are crucial elements of glaciers and ice sheets because they modulate ice flow velocity. However, logistical challenges of measuring subglacial processes beneath contemporary ice and natural limitations in long-term monitoring

Holocene vegetation dynamics of Grande Terre (Kerguelen Islands) inferred from sedimentary ancient DNA

Journal of Quaternary Science, EarlyView.
ABSTRACT While the Antarctic region has experienced significant climatic changes over the Holocene, few high‐resolution records have examined their effects on the local biota. In order to understand past ecological shifts and forecast future changes, it is important to obtain high‐resolution palaeoecological records from this region.

Contrasting glacial meltwater effects on post-bloom phytoplankton on temporal and spatial scales in Kongsfjorden, Spitsbergen

Elementa: Science of the Anthropocene, 2018
Glacial meltwater discharge in fjords on the west coast of Spitsbergen is increasing due to climate change. The influence of this discharge on phytoplankton nutrient limitation, composition, productivity and photophysiology was investigated in central (M)

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

Journal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Long‐Term Operation of Photovoltaic Power Stations Promotes Soil Carbon Sequestration but Induces Stoichiometric C:N:P Imbalance in Desert Ecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Soil carbon‐nitrogen‐phosphorus (C:N:P) stoichiometry governs nutrient cycling and carbon sequestration in desert ecosystems, yet how large‐scale photovoltaic (PV) deployment, a cornerstone of global carbon neutrality, shifts these stoichiometric balances and whether such shifts enhance or degrade long‐term land function remain unresolved over

Hunting Strategies and Game Exploitation Organization in the Magdalenian: An Integrated Approach Based on Mortality Profiles and Stable Isotopes at Chaves Cave (Huesca, Spain)

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Understanding hunting strategies in Upper Paleolithic contexts remains challenging due to the complex relationships between prey behavior, environmental conditions, and human decision‐making. Addressing these dynamics requires integrating archeozoological, geospatial, and geochemical proxies capable of capturing demographic patterns, landscape

Models of ice melting and edifice growth during subglacial basaltic eruptions. [PDF]

, 2007
Models of the early stages of basaltic eruptions beneath temperate glaciers are presented that consider the evolving sizes of volcanic edifices emplaced within subglacial cavities.

Meltwater markedly exacerbates socioeconomic exposure to floods in the eastern Himalaya

Environmental Research Letters
Flood hazards across high mountain Asia present pronounced complexity due to the combined influence of rainfall, meltwater, and glacial lake outburst floods (GLOFs).

Ice-dammed lake and ice-margin evolution during the Holocene in the Kangerlussuaq area of west Greenland

Arctic, Antarctic, and Alpine Research, 2018
There is a lack of detailed information on the Holocene evolution of the west Greenland ice margin, not least because it was farther inland than at present and thus at present is covered by ice. Suggestions have been put forward, both of relatively quick
