Investigation of Crevasse Evolution, Calving Occurrence, and Links to Damage (ICECOLD), RiS ID 6155

Iceberg calving is an important component of glacier mass loss and indirectly contributes to sea level rise. A new iceberg calving law was recently proposed based on damage mechanics, a promising new theory that could greatly improve the ability of ice s heet models to predict the response of gl...

Spatiotemporal changes in vegetation following range expansion in Svalbard reindeer

In 1978, Svalbard reindeer (Rangifer tarundus platyrhynchus) were re-introduced by humans to the Ny-Ålesund area following ca 100 yrs of absence due to excessive hunting. The population irrupted and gradually expanded its range to include other areas such as Sarsøyra and Kaffiøyra. This natural ...
