Extreme marine environments cover more than 50% of the Earth's surface and offer many
opportunities for investigating the biological responses and adaptations of organisms to …

Carbon is one of the key elements in organisms and non-living compounds on Earth.
Carbon dioxide and methane are important greenhouse gases in the atmosphere, dissolved …

Oxygen minimum zones (OMZs; midwater regions with O2 concentrations< 0.5 ml l− 1) are
mid‐water features that intercept continental margins at bathyal depths (100–1000 m). They …

Fossil benthic foraminifera are used to trace past methane release linked to climate change.
However, it is still debated whether isotopic signatures of living foraminifera from methane …

Cold seep foraminifera have attracted considerable attention as they provide valuable
insights into the study of cold seeps. This study provides a comprehensive overview of the …

We present results from a sediment core collected from a pockmark field on the Vestnesa
Ridge (~ 80° N) in the eastern Fram Strait. This is the only deep-water gateway to the Arctic …

Anomalously low δ 13 C values in foraminiferal calcite tests are due to diagenetic alteration
in methane seep sites. Our study applies diagenetically altered fossil benthic foraminiferal …

Multiple proxies in the geological record offshore NW Svalbard track shallow subseafloor
diagenesis and seafloor methane seepage during the Last Glacial Maximum (LGM) extent …

The effect of see** of methane on marine sediment records has been studied in four
gravity cores from Vestnesa Ridge, Svalbard margin. The area shows acoustic signs in the …

Negative stable carbon isotopic excursions have been observed throughout most of the mid‐
depth (~ 1000–3000 m) Atlantic Ocean during Heinrich Stadial 1 (HS1) and the Younger …
