Long time series are important for understanding changes in nature. Despite extensive research on vegetation in Svalbard, long-term monitoring has been lacking. But we can now present “Year 1” of Svalbard vegetation monitoring within COAT.

This year's snow measurements in Komagdalen and Vestre Jakobselv have been carried out

Snow measurements are an important part of the monitoring done in COAT – snow is indeed an important driver of many processes underlying dynamics of arctic ecosystems. The measurements we do focus on simple measurements of snow depths in different habitats (snowbeds, hummock, meadow, heath), as well as much more detailed assessment of the different...

Understanding and predicting how climate change impacts Svalbard ptarmigan population dynamics

Iterative near-term forecasting is a promising approach to better understand and manage rapidly changing ecosystems such as the Arctic. Forecasts generated on a short-term time scale allow scientific hypotheses to be tested more frequently, speeding up scientific advancement, and are relevant to managers because the time scale can be influenced by...

Red fox traps placed in Varanger

In the first week of February, a small team from COAT and local experts Alfred Ørjebu and John Arne Kristiansen placed 3 wooden box traps designed for live trapping red foxes in southeastern Varanger peninsula. The effort is part of a new research project that attempts to deploy GPS collars on red foxes to investigate their movement behavior as pa...

New method: Chemical traits of single leaves using near‐infrared reflectance spectroscopy (NIRS)

Measures of plant chemical traits are often achieved by merging several leaves, masking potential foliar variation within and among plant individuals. In a new study , COAT researchers developed a new application of Near-infrared Reflectance Spectroscopy (NIRS) methodology that provides measures of carbon, nitrogen, phosphorus, and silicon from ...

Vegetation fieldwork Varanger 2020

Vegetation monitoring was carried out in late July and early August in Komagdalen and Vestre Jakobselv on the Varanger peninsula. Besides the annual monitoring in heath and meadow sites, the fieldteam also conducted point intercept frequency in newly established heath sites further away from the productive river valleys.

This year's Svalbard summer is the warmest on record

The average temperature for June, July and August at Svalbard Airport was 7.2 degrees, which is 3 degrees above normal, and 0.5 degrees above the old summer record from 2015. For Svalbard Airport, a series of measurements dating back to 1899 has been prepared. This year's summer is extreme. It joins the ranks of hot summers for the last 20 to 30 y...

Good news from the arctic foxes in Varanger

There were five dens with confirmed reproduction this summer, despite the low small rodent abundance. Three were in the eastern half of the Peninsual and two further to the west. It is likely that there were some places with some remaining lemmings, as quite a few lemming remains were found on at least one den.

The annual vegetation monitoring in Svalbard was successfully carried out

Thanks to local forces already in Svalbard and Ingrid traveling up, the annual vegetation monitoring in Svalbard was successfully carried out despite restrictions to travel due to covid-19.

COAT has established a monitoring system for the invasive Eastern European vole (formerly named the Sibling vole) in Svalbard

The new Reconyx cameras adapted to COAT’s small mammal photoboxes arrived (at last!) in August and have just enabled us to finalize the monitoring system for the invasive Eastern European vole (formerly named the Sibling vole) in Svalbard.
