The steady loss – Palynological investigation into the main triggers of changes in vegetation and pastoral activity during the Norse period in southern Greenland Open
Pastoral farming formed a key element of Norse subsistence strategies in South Greenland but with climatic changes of the Little Ice Age they may have reached their limit. Most recently, studies into hydrological changes across the Norse p…

Two millennia of climate change, wildfires, and caribou hunting in west Greenland Open
Changing climatic conditions is a perpetual circumstance for mankind. In this study, we investigate local environmental and climatic changes near Kangerlussuaq, west Greenland. Our reconstruction is based on a lake sediment core and method…

Late glacial and Holocene glaciation history of North and Northeast Greenland Open
Northeast Greenland is the place where the Greenland Ice Sheet (GrIS) experienced the largest areal changes since the Last Glacial Maximum. However, the age constraints of the last deglaciation are in some areas sparse. In this study, we u…

Vulnerability of the North Water ecosystem to climate change Open
High Arctic ecosystems and Indigenous livelihoods are tightly linked and exposed to climate change, yet assessing their sensitivity requires a long-term perspective. Here, we assess the vulnerability of the North Water polynya, a unique se…

Glacial history of the Greenland Ice Sheet and a local ice cap in Qaanaaq, northwest Greenland Open
In this study, we present new information on the glacial history of the Greenland Ice Sheet (GrIS) and a local ice cap in Qaanaaq, northwest Greenland. We use geomorphological mapping, 10 Be exposure dating of boulders, analysis of lake co…

Relative Sea-Level Changes and Ice Sheet History in Finderup Land, North Greenland Open
Rising global sea level caused by melting ice sheets poses a major challenge ina persistently warming climate. The Greenland Ice Sheet (GrIS) is among the maincontributors, and in order to make accurate predictions of future ice retreat an…

One million years of glaciation and denudation history in west Greenland Open
The influence of major Quaternary climatic changes on growth and decay of the Greenland Ice Sheet, and associated erosional impact on the landscapes, is virtually unknown beyond the last deglaciation. Here we quantify exposure and denudati…

Greening the high Arctic : When and how have seabirds transformed the fresh waters of the NOW Polynya? Open
The North Water Polynya (NOW) is host to an exceptionally large number of seabirds, which gather in large colonies over the brief summer months. These birds link marine and terrestrial ecosystems as they rely on the productivity of the mar…
