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.

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 ...

Die Arktische Oszillation im Kieler Klimamodell [PDF]

, 2010
The Arctic Oscillation (AO) is the dominant mode of variability of the mean sea level pressure (MSLP) in the Northern hemisphere. It is a result of an EOF-analysis for SLP3 anomalies during winter. Because of a decisive influence of the AO on atmospheric

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

Auf dünnem Eis? Eisdickenänderungen im Nordpolarmeer [PDF]

, 2006
While the summer sea ice extent has beendecreasing in the Artic by 8% per decade for the past 30 years,the ice extent has actually increased slightlyin the Antarctic. Ice thickness changes are less well known. In the central Arctic, sea ice thinned by 43%
