Climate-Ecological Observatory for Arctic Tundra (COAT) — Adaptive system for long-term terrestrial monitoring

, 2021
This is chapter 2 of the State of Environmental Science in Svalbard (SESS) report 2021. Predicted temperature increases in the Arctic are expected to fundamentally alter tundra ecosystem dynamics.

Circulation and exchange in a broad Arctic fjord using glider-based observations

Polar Research, 2018
In recent years, Svalbard fjords have experienced a substantial reduction in winter sea-ice extent. This has been linked to changes in wind stress patterns over Fram Strait and an increased transport of warm Atlantic Water into the fjords.

Eddy kinetic energy and energy conversion rates along the Atlantic Water boundary current north of Svalbard [PDF]

Ocean Science
On the continental slope north of Svalbard, the boundary current carrying Atlantic Water (AW) loses heat as it flows eastward. This cooling cannot be fully attributed to atmospheric heat loss or turbulent mixing.

Competition and soil conditions limit the growth of High Arctic non‐native plants

Oikos, EarlyView.
Non‐native vascular plant species in the High Arctic are currently restricted mainly to settlements and other anthropogenically disturbed areas. The reasons for this remain unclear, but climate or dispersal do not appear to be the main limiting factors. Instead, biotic interactions combined with soil conditions may play important roles.

Estimation of gas hydrate concentration from multi-component seismic data at sites on the continental margins of NW Svalbard and the Storegga region of Norway [PDF]

, 2008
High-resolution seismic experiments, employing arrays of closely spaced, four-component ocean-bottom seismic recorders, were conducted at a site off western Svalbard and a site on the northern margin of the Storegga slide, off Norway to investigate how ...

Cratering behaviour and faecal C:N ratio in relation to seasonal snowpack characteristics in a High-Arctic ungulate

Polar Research, 2017
Snow and ice determine winter forage availability for Arctic herbivores. Winter precipitation is anticipated to increase, and icing following warm spells and rain-on-snow (ROS) are likely to become more frequent. While this may reduce herbivore survival,

The influence of local winds on wind power characteristics in a High Arctic valley [PDF]

Wind Energy Science
Wind power in the High Arctic is under-developed, and understanding of the local wind conditions is needed. Therefore, the average wind characteristics in the Svalbard valley Adventdalen are investigated using primarily observations from wind profilers ...

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

Oikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.

High-resolution digital outcrop model of the faults, fractures, and stratigraphy of the Agardhfjellet Formation cap rock shales at Konusdalen West, central Spitsbergen [PDF]

Earth System Science Data
Structure-from-motion (SfM) photogrammetry has become an important tool for the digitalisation of outcrops as digital outcrop models (DOMs). DOMs facilitate the mapping of stratigraphy and discontinuous structures like folds, faults, and fractures from ...

Enhance food plant diversity conservation and use through greater coordination between genebanks and botanic gardens

PLANTS, PEOPLE, PLANET, EarlyView.
Food plants are vital to human and planetary health, but their diversity is threatened, making food security, nutrition, and environmental goals more difficult to achieve. Food plant diversity conservation, research, and education can be enhanced through collaboration between sectors, including genebanks and botanic gardens, which possess complementary
