Eye lens radiocarbon reveals centuries of longevity in the Greenland shark (Somniosus microcephalus)

Science, 2016
Deep living for centuries We tend to think of vertebrates as living about as long as we do, give or take 50 to 100 years. Marine species are likely to be very long-lived, but determining their age is particularly difficult. Nielsen et al.

Developments in Permafrost Science and Engineering in Response to Climate Warming in Circumpolar and High Mountain Regions, 2019–2024

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Research in geocryology is currently principally concerned with the effects of climate change on permafrost terrain. The motivations for most of the research are (1) quantification of the anticipated net emissions of CO2 and CH4 from warming and thaw of near‐surface permafrost and (2) mitigation of effects on infrastructure of such warming and

Citizen Seismology in the Arctic

Frontiers in Earth Science, 2020
Landslides, earthquakes and other natural disasters are expected to increase in the Arctic, yet our ability to make informed decisions about safety is tightly limited by lack of data. As part of the Integrated Arctic Observation System (INTAROS) project,

Non-linear response of summertime marine productivity to increased meltwater discharge around Greenland

Nature Communications, 2018
Runoff from the Greenland Ice Sheet (GrIS) is thought to enhance marine productivity by adding bioessential iron and silicic acid to coastal waters. However, experimental data suggest nitrate is the main summertime growth-limiting resource in regions ...

Atmospheric River Impacts on Greenland Ice Sheet Surface Mass Balance

Journal of Geophysical Research: Atmospheres, 2018
Greenland Ice Sheet (GrIS) mass loss has accelerated since the turn of the twenty‐first century. Several recent episodes of rapid GrIS ablation coincided with intense moisture transport over Greenland by atmospheric rivers (ARs), suggesting that these ...

Q Fever in Greenland

Emerging Infectious Diseases, 2010
We report a patient with Q fever endocarditis in a settlement in eastern Greenland (Isortoq, Ammassalik area). Likely animal sources include sled dogs and seals. Q fever may be underdiagnosed in Arctic areas but may also represent an emerging infection.

Signal‐to‐noise errors in early winter Euro‐Atlantic predictions linked to weak ENSO teleconnections and pervasive jet biases

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Early winter seasonal predictability over the Euro‐Atlantic is strongly tied to the El Niño–Southern Oscillation (ENSO) teleconnection to the North Atlantic, though responses to ENSO are systematically too weak in state‐of‐the‐art models. The model signal‐to‐noise errors are strongly dependent on the strength of the ENSO teleconnection in the models ...

The social and organisational factors shaping acceptability of a self-management education and exercise intervention for people with hip or knee osteoarthritis in Greenland

International Journal of Circumpolar Health
This study aimed to explore the experiences and perspectives of people with osteoarthritis attending the “Osteoarthritis School” (OA School) in Nuuk, Greenland to generate insights and lessons that can inform the development of self-management education ...

Greenland‐Wide Seasonal Temperatures During the Last Deglaciation

, 2018
The sensitivity of the Greenland ice sheet to climate forcing is of key importance in assessing its contribution to past and future sea level rise.

Air–sea–ice interactions in Isfjorden, Svalbard: An atmospheric perspective

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Due to its location and complex topography, atmospheric conditions in the Isfjorden region in central Svalbard are highly variable in space and time. Using new high‐resolution atmospheric reanalysis data, we show that near‐surface wind channeling and cold air advection strongly impact the winter heat extraction from the fjord, comparable to the effect ...
