The cycling of carbon on Earth exerts a fundamental influence upon the greenhouse gas
content of the atmosphere, and hence global climate over millennia. Until recently, ice …

Marine cold seeps are windows into different depth levels of the submerged geosphere.
Subduction zones and organic-rich passive margins host most of the world's cold seeps. The …

Methane is the second most important greenhouse gas contributing to climate warming. The
open ocean is a minor source of methane to the atmosphere. We report intense methane …

Permanently cold marine sediments are heavily influenced by increased input of iron as a
result of accelerated glacial melt, weathering, and erosion. The impact of such …

Antarctica is estimated to contain as much as a quarter of earth's marine methane, however
we have not discovered an active Antarctic methane seep limiting our understanding of the …

In response to the accelerating processes of marine natural gas hydrate exploration and gas
production from hydrate-bearing sediments, their potential impacts on the environment have …

Widespread seepage of methane from seafloor sediments offshore Svalbard close to the
landward limit of the gas hydrate stability zone (GHSZ) may, in part, be driven by hydrate …

Power stations, ships and air traffic are among the most potent greenhouse gas emitters and
are primarily responsible for global warming. Iron salt aerosols (ISAs), composed partly of …

How much of the greenhouse gas methane is transported from the seafloor to the
atmosphere is unclear. Here, we present data describing an extensive ebullition event that …

Fjords are recognized as hotspots of organic carbon (OC) burial in the coastal ocean. In
fjords with glaciated catchments, glacier discharge carries large amounts of suspended …
