3D visualation in research: A 3D representation of the glacier elevation changes around Daugaard Jensen glacier from 1987 to 2014. The image is the 1987 orthophoto and the elevation change color scale ranges from ­1 to 0.5 meters per year. Data and differences as described in Scientific Data (Korsgaard, Nuth et. al. 2016)

Recently, a Danish-Norwegian research team re-processed thousands of aerial photos into 3D Digital Elevation Models (DEM) surrounding the entire coastline of Greenland. The new data extends the precise geometric record of Greenland glacier margins to the late 1970s and 80s and can be used to quantify the decline in the ice mass, for example. The data is freely available to the public domain.

Stipendiat Johanne H. Rydsaa ved Institutt for geofag har leia ein studie der dei har sett på effekt av gjengroing av den norske fjellheimen. Meir vegetasjon i fjellheimen bidrar til eit mildare klima og global oppvarming, men beitedyra kan halda gjengroinga i sjakk. Les meir om dette i Nationen.

The American magazine The New Yorker recently followed a research team collecting data from the Chhota Shigri Glacier in India. In the article they followed among others postdoc Markus Engelhardt, Department of Geosciences in his work to check the camp’s weather monitor, which had been planted four months earlier, and recorded temperature, solar radiation, and barometric pressure.  The aim of the study is to find out if and how fast the glacier is melting.

Alle som er glad i å ferdes i norsk natur vet at de ofte kan støte på myrlendt terreng. Inntil nå har det vært stor usikkerhet om hvor stort areal denne landskapstypen utgjør, men en kartlegging i 2015 (NIBIO) viser at det er et betydelig areal. LATICE forskere m.fl. har en kronikk i Nationen (19.03.16) om utbredelse og betydningen myra har som ressurs, og for eksempel som karbonlager.

50 METRES HIGH: Most glaciers in the world are classic calving glaciers, like the Lilliehöök glacier in Northern Svalbard. Its front is to kilometers wide and almost 50 metres high. Every time it calves, huge roars can be heard across the fjord. The researchers have now examined another type of glaciers that behave very differently. Photo: Yngve Vogt

Many glaciers on Svalbard behave very differently from other glaciers worldwide. They advance massively for some years and then quickly retreat – and then remain quiescent for fifty to a hundred years – before they once again start to advance.
