Suitable habitats of fish species in the Barents Sea
Fisheries Oceanography, Volume 29, Issue 6, Page 526-540, November 2020., 2020 Abstract Many marine species exhibit poleward migrations following climate change. The Barents Sea, a doorstep to the fast‐warming Arctic, is experiencing large scale changes in its environment and its communities. Tracking and anticipating changes for management and conservation purposes at the scale of the ecosystem necessitate quantitative knowledge

Parameterization of the downward long-wave radiation at the Earth’s surface in polar regions
Meteorologische Zeitschrift, 1994 Various parameterization schemes for the downward long-wave radiation at the Earth's surface which have been frequently applied in sea ice and snow cover models are tested with the aid of one year's measurements at the German stations "Koldewey" and ...

Biologie in unserer Zeit, Volume 50, Issue 2, Page 122-133, April 2020., 2020 Die saisonal eisfreien Gebiete der Antarktis beherbergen eine überraschend artenreiche Vegetation aus Algen, Moosen, Pilzen und Flechten. Konkurrenz durch Gefäßpflanzen gibt es hier nicht. Aber dafür eisige Kälte, extreme Trockenheit und monatelange Dunkelheit. Wie kann die antarktische Vegetation dem trotzen?

Physik in unserer Zeit, Volume 51, Issue 2, Page 79-85, March 2020., 2020 Der globale Klimawandel nimmt Fahrt auf. Aber woher wissen wir eigentlich, dass er durch den Treibhauseffekt verursacht wird und nicht durch eine aktiver werdende Sonne? Einfache physikalische Überlegungen zeigen, warum sich Änderungen im Treibhauseffekt anders auf Erwärmungsmuster niederschlagen als Änderungen in der Solarstrahlung. Daran kann man den

Quantifying the Potential for Snow‐Ice Formation in the Arctic Ocean
Geophysical Research Letters, Volume 47, Issue 4, 28 February 2020., 2020 Abstract We examine the regional variations and long‐term changes of the potential for snow‐ice formation for level Arctic sea ice from 1980 to 2016. We use daily sea ice motion data and implement a 1‐D snow/ice thermodynamic model that follows the ice trajectories while forcing the simulations with Modern‐Era Retrospective analysis for Research and ...

Pressurised xenon as scintillator for gamma spectroscopy
, 2013 Detectors based on liquid or gas xenon have been used and are in use for a number of applications, in particular for the detection of gamma rays. Xenon is a well-suited medium for gamma spectroscopy thanks to its high atomic number and, consequently ...

Norge og EU – partnere i Arktis
Nordlit: Tidsskrift i litteratur og kultur, 2012 This article raises three main questions: (i) What characterizes the EEC/EU's relationship to the Arctic? (ii) What issues/areas have caused problems for the EU in becoming a more relevant actor in the Arctic? (iii) To what degree has Norway been able to
