Microbial transformation of hydrocarbons to methane is an environmentally relevant process
taking place in a wide variety of electron acceptor-depleted habitats, from oil reservoirs and …

Volatile fatty acids (VFAs) are key intermediates in the anaerobic mineralization of organic
matter in marine sediments. We studied the role of VFAs in the carbon and energy turnover …

With climate change, the strong seasonality and tight pelagic-benthic coupling in the Arctic is
expected to change in the next few decades. It is currently unclear how the benthos will be …

Composite tailings (CT), an engineered, alkaline, saline mixture of oil sands tailings (FFT),
processed sand and gypsum (CaSO 4; 1 kg CaSO 4 per m 3 FFT) are used as a dry …

Process-based, mechanistic investigations of organic matter transformation and diagenesis
directly beneath the sediment–water interface (SWI) in Arctic continental shelves are vital as …

The Arctic Baffin Bay between Canada and Greenland is sea ice-covered during the majority
of the year, restricting primary production to the summer months. Sediments receive low …

Bacteria of the class D ehalococcoidia (DEH)(phylum C hloroflexi) are widely distributed in
the marine subsurface and are especially prevalent in deep marine sediments …

The Arctic, an essential ecosystem on Earth, is subject to pronounced anthropogenic
pressures, most notable being the climate change and risks of crude oil pollution. As crucial …

Abstract The hadal trenches (> 6000 m) are considered to be ultimate sinks of organic
carbon (OC) from biosphere. However, highly spatial heterogeneity of geographic …

The Barents Sea shelf is one of the most economically promising regions in the Arctic in
terms of its resources and geographic location. However, benthic microbial communities of …
