Modeling convection in the Greenland Sea
… of a deep convection event observed in the Greenland Sea in 1988-89 is carried out through a combination of modeling, scale estimates, and data analysis. We develop a prognostic one-dimensional mixed layer model which is coupled to a thermodynamic ice model. Our model contains a …

Palaeobiology of Silurian trilobites from North Greenland
… Telychian (Llandovery, Silurian) reefs of North Greenland yield extensive collections of diverse and remarkably well preserved trilobites. The collections comprise 36 named trilobite species (32 new), and 30 under open nomenclature. These are assigned to 32 genera (six new). Members of the …

The origins of the East Greenland Coastal Current on the Northeast Greenland Shelf: a comparison of two reanalysis products
The East Greenland Coastal Current (EGCC) carries some of the freshest outflow from the Arctic southward along the East Greenland Shelf and into the Nordic Seas and subpolar North Atlantic. How this fresh water initially flows onto the Northeast Greenland Shelf (NEGS) and feeds the EGCC is not well …

Influence of meltwater on Greenland Ice Sheet dynamics
… meltwater control ice-flow processes across the Greenland Ice Sheet ablation zone and subglacial discharge at marine-terminating outlet glaciers. With the increase in annual ice sheet meltwater production observed over recent decades and predicted into future decades, understanding mechanisms …

Supraglacial lake evolution on the Greenland Ice Sheet
… lakes form annually on the surface of the Greenland Ice Sheet around Paakitsoq, north of the Jakobshavn Isbrae outlet glacier. The lakes are ephemeral, drain through moulins or crevasses at their bed throughout the melt season, and deliver large volumes of water to the subglacial …

Modelling the Hydrology of the Greenland Ice Sheet
… increasing recognition that the hydrology of the Greenland Ice Sheet plays an important role in the dynamics and therefore mass balance of the ice sheet. Understanding the hydrology of the ice sheet and being able to predict its future behaviour is therefore a key aspect of glaciological research. …

Investigating fast flow of the Greenland Ice Sheet
The dynamic response of a faster-flowing Greenland Ice Sheet to climate change is modulated by feedbacks between ice flow and surface meltwater delivery to the basal environment. While supraglacial melt processes have been thoroughly examined and are well constrained, the response of the englacial …

Extensional evolution of the central East Greenland Caledonides
… laboratory investigations in the central East Greenland Caledonides. During the course of this work, attempts were made to answer some of the outstanding regional and local questions in East Greenland geology. Structural, U-Pb and ⁴⁰Ar/³⁹Ar geochronologic, petrographic and thermobarometric data …

Late Quaternary ice-ocean interactions in central West Greenland
… knowledge of the interactions between the Greenland Ice Sheet and climate is critical to understanding the possible impacts of future global warming, including ice sheet contribution to global sea-level rise and perturbations to ocean circulation. Recent acceleration, thinning and retreat …

Glaciological investigations in east greenland using digital landsat imagery
Sixteen late summer Landsat MSS scenes of East Greenland from 1986 to 1989 were acquired for use in glaciological and marine geological investigations. Drainage basin areas and snowline elevations were determined for 74 tidewater glaciers in the study area, and turbid meltwater plumes were …

Hydrological and biogeochemical cycling along the Greenland ice sheet margin
… warming has led to a significant increase in Greenland ice sheet (GrIS) melt and runoff since 1990, resulting in escalated export of fresh water and associated sediment to the surrounding North Atlantic and Arctic Oceans. Similar to alpine glacial systems, surface meltwater on ice sheet …

Historical Ecology of Norse Greenland: Zooarchaeology and Climate Change Responses
… of cultural landscapes and seascapes in Norse Greenland. It also investigates climate impacts on human economic strategies, as they vary substantially by island and region in the North Atlantic but were especially important in arctic Greenland.</p> <p>The analysis centers on the animal bone …
