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.

The summer temperature varies somewhat from year to year. Until about 1990, this variation was typically 0.5 to 1 degrees, with single years of 1.5 degrees above or below normal. During the 90s there was a marked change, and after 1997 we have not registered summers with average temperatures below normal. We see a clear trend with warmer and warmer summers. This year's summer is exceptional. The curve shows adjusted smoothed summer temperature with variations on a 10-year scale. Figure: Ketil isaksen / MET

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...
