Geochemical and micropalaeontological analyses conducted on two dated sediment cores from the Hvaler estuary (SE Norway) indicate a relationship between the darkening phenomenon of Skagerrak coastal waters and an increase ...

Abstract
Observations show increases in river discharge to the Arctic Ocean especially in winter over the last decades but the physical mechanisms driving these changes are not yet fully understood. We hypothesize ...

Abstract The two most abundant minerals in the Earth’s lower mantle are bridgmanite and ferropericlase. The bulk modulus of ferropericlase (Fp) softens as iron d-electrons transition from a high-spin to low-spin state, ...

In the Carrazeda de Ansiães region, northern Portugal, a mesozonal granitic suite intruded Precambrian to Ordovician metasedimentary rocks during the late kinematic stages of the Variscan orogeny. In this multiphase granitic ...

Abstract Exceptional magmatic events coincided with the largest mass extinctions throughout Earth’s history. Extensive degassing from organic-rich sediments intruded by magmas is a possible driver of the catastrophic ...

Abstract While a rapid sea ice retreat in the Arctic has become ubiquitous, the potential weakening of the Atlantic meridional overturning circulation (AMOC) in response to global warming is still under debate. As deep ...

Supraglacial debris affects glacier mass balance as a thin layer enhances surface melting, while a thick layer reduces it. While many glaciers are debris-covered, global glacier models do not account for debris because its ...

The climatic and environmental impact of exclusively volcanic CO2 emissions is assessed during the main effusive phase of the Central Atlantic Magmatic Province (CAMP), which is synchronous with the end-Triassic mass ...

A warm phase has previously been observed in the early to middle Holocene geological record of the Northern hemisphere. Holocene invertebrate faunas in the Oslo fjord, Norway, are here studied in order to investigate their ...

I alpine høyfjellsområder fører klimaendringene til at breene trekker seg tilbake, og permafrosten i fjellet varmes opp og tiner. Konsekvensene klimaet har for fjellsporten er imidlertid et lite studert tema. Dette er en ...
