Abstract Hydrate Ridge, Cascadia convergent margin, is characterized by abundant methane hydrates at and below the seafloor, active venting of fluids and gases, chemosynthetic communities composed of giant sulfide-oxidizing bacteria and clams, authigenic carbonates, and some of the highest...

Holler T, Wegener G, Knittel K, Boetius A, Brunner B, Kuypers MM, Widdel F.
PMID: 23765889
Environ Microbiol Rep. 2009 Oct;1(5):370-6. doi: 10.1111/j.1758-2229.2009.00074.x. Epub 2009 Sep 23.

The anaerobic oxidation of methane (AOM) by methanotrophic archaea and sulfate-reducing bacteria is the major sink of methane formed in marine sediments. The study of AOM as well as of methanogenesis in different habitats is essentially connected with the...

Influence of ice thickness and surface properties on light transmission through Arctic sea ice.

Microbial communities of the Arctic Ocean are poorly characterized in comparison to other aquatic environments as to their horizontal, vertical, and temporal turnover. Yet, recent studies showed that the Arctic marine ecosystem harbors unique microbial community members that are...

In situ observation of sponge trails suggests common sponge locomotion in the deep central Arctic.

In 2016, the research ice-breaker Polarstern surveyed the submerged peaks of the permanently ice-covered Langseth Ridge, a tectonic feature comprising the Karasik seamount and two deeper seamount peaks, abutting the Gakkel ultra-slow spreading ridge (87°N 62°E to 85.5°N 57.4°E)
