The Greenland Ice-Marginal Lake Inventory Series from 2016 to 2023 [PDF]

Earth System Science Data
Ice-marginal lakes form at the edge of the Greenland Ice Sheet and its surrounding peripheral glaciers and ice caps (PGIC), where outflowing glacial meltwater is trapped by a moraine, or by the ice itself, and create a reservoir that is in contact with ...

A Sea‐Ice‐Enhanced KPP Parameterization: Impacts on AMOC Simulation and Physical Pathways

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract This study presents a sea‐ice‐enhanced K‐profile parameterization to improve simulations of the Atlantic Meridional Overturning Circulation (AMOC) in ocean–sea ice coupled models. The modified KPP dynamically scales the background vertical diffusivity with local sea‐ice fraction, representing the insulating and turbulence‐suppressing effects ...

Thermodynamic Constraints on H2 Production and Habitability From Mg‐Rich Serpentinites as Mars Analogs

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Serpentinization produces hydrogen and methane through abiotic water‐rock interactions, potentially supporting chemotrophic life in planetary subsurface environments. Serpentine deposits in the Martian Noachian landscapes of Nili Fossae and the Southern Highlands have been considered as potential paleo‐habitable zones. However, the geochemical

Mapping the vertical heterogeneity of Greenland's firn from 2011–2019 using airborne radar and laser altimetry [PDF]

The Cryosphere
The firn layer on the Greenland Ice Sheet (GrIS) plays a crucial role in buffering surface meltwater runoff, which is constrained by the available firn pore space and impermeable ice layers that limit deeper meltwater percolation.

A predictive model for the wettability of chalk

SN Applied Sciences, 2020
Wettability is usually measured in special core analyses of limited plug samples according to typically costly and time-consuming procedures. For comparative purposes, wettability is considered an index.

Characterising brines in deep Mesozoic sandstone reservoirs, Denmark

Geological Survey of Denmark and Greenland Bulletin, 2019
The Danish subsurface contains several sandstone units, which represent a large geothermal resource (Vosgerau et al. 2016). Currently, only three geothermal plants are operating in Denmark, but several exploration licences are expected to be awarded in ...

A chemistry and microbiology data set for meltwater rivers in south-western Greenland (2017–2021)

GEUS Bulletin
Meltwater rivers in Greenland transport large quantities of freshwater from the Greenland ice sheet and local glaciers to the ocean, significantly influencing marine ecosystems and global biogeochemical cycles.

Quantifying the surface energy fluxes in South Greenland during the 2012 high melt episodes using in-situ observations

Frontiers in Earth Science, 2016
Two high melt episodes occurred on the Greenland ice sheet in July 2012, during which nearly the entire ice sheet surface experienced melting. Observations from an automatic weather station (AWS) in the lower ablation area in South Greenland reveal the ...
