Die Geopolitik der Arktis

Zeitschrift für Außen- und Sicherheitspolitik
Die geopolitische Bedeutung der Arktis beruht auf ihrer Lage am Atlantik und Indopazifik, zwischen den USA und Russland und ihrem wirtschaftlichen Potential, insbesondere infolge des Schmelzens des Eises aufgrund der globalen Erwärmung.

Marine Cloud Brightening to Cool the Arctic: An Earth System Model Comparison

Earth's Future, Volume 13, Issue 12, December 2025.
Abstract Marine cloud brightening (MCB) via sea‐salt aerosol (SSA) injections is one commonly researched method to cool the Earth either regionally or globally, and potentially reduce impacts of global warming. There is evidence from both high‐resolution climate modeling and natural analogs that the introduction of aerosols in the Arctic atmosphere ...

Seasonal changes in the feeding aggregation structure of male sperm whales (Physeter macrocephalus) in Northern Norway

Marine Mammal Science, Volume 41, Issue 3, July 2025.
Abstract The sperm whale (Physeter macrocephalus) is one of the most widely distributed cetaceans. Adult males commonly occupy high latitudes, whereas females and juveniles occupy lower latitudes. In Northern Norway, previous studies focused on the summer period limiting our understanding of the seasonal dynamics of male foraging aggregations.

Marine‐derived nutrients shape the functional composition of High Arctic plant communities

Functional Ecology, Volume 39, Issue 6, Page 1606-1621, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Low temperatures and nutrient limitation have shaped Arctic plant communities, which are now affected by biome‐wise changes in both climate and nutrient cycling. Rising temperatures are favouring taller plant species with more resource‐acquisitive traits across the ...

Analysis of the scintillation mechanism in a pressurized 4He fast neutron detector using pulse shape fitting

AIP Advances, 2015
An empirical investigation of the scintillation mechanism in a pressurized 4He gas fast neutron detector was conducted using pulse shape fitting. Scintillation signals from neutron interactions were measured and averaged to produce a single generic ...

The Cumulative Effect of Various Tillage Systems and Stubble Management on the Biological and Chemical Properties of Soil in Winter Wheat Monoculture

Agronomy, 2021
Agricultural practices, including tillage systems and postharvest residue management, strongly affect a wide range of soil properties. Depending on the degree of soil inversion, both negative and beneficial changes of its structure, chemical composition,

Testing the deep‐sea glacial disturbance hypothesis as a cause of low, present‐day Norwegian Sea diversity and resulting steep latitudinal diversity gradient, using fossil records

Global Ecology and Biogeography, Volume 33, Issue 7, July 2024.
Abstract Aim Within the intensively‐studied, well‐documented latitudinal diversity gradient, the deep‐sea biodiversity of the present‐day Norwegian Sea stands out with its notably low diversity, constituting a steep latitudinal diversity gradient in the North Atlantic. The reason behind this has long been a topic of debate and speculation.

Deep Mantle Component and Continental Crust Remobilization in the Source of Vesteris Seamount, East Greenland Margin

Geochemistry, Geophysics, Geosystems, Volume 25, Issue 1, January 2024.
Abstract Vesteris Seamount is a large Quaternary intraplate submarine volcano in the SW Greenland Sea, about 1,000 km NE of Iceland and 300 km NW of the Mohn's spreading ridge, whose mode of formation remains unsolved. We present geochemical data for new samples dredged from the Vesteris edifice, including major, trace elements and Sr‐Nd‐Pb‐Hf isotopes.

Nansen i norsk polartradisjon

Nordlit: Tidsskrift i litteratur og kultur, 2014
Fridtjof Nansen’s expeditions introduced polar exploration in Norway. And his stories from the North formed our image of the Arctic. For later generations of Norwegian explorers Nansen surely has been a great inspiration. Also within polar science Nansen
