A site at the gas hydrate stability limit was investigated offshore northwestern Svalbard to study methane transport in sediment. The site was characterized by chemosynthetic communities (sulfur bacteria mats, tubeworms) and gas venting. Sediments we

Microbial life inhabiting subseafloor sediments plays an important role in Earth’s carbon cycle. However, the impact of geodynamic processes on the distributions and carbon-cycling activities of subseafloor life remains poorly constrained. We explo

What Does It All Mean? Strong emissions of methane have recently been observed from shallow sediments in Arctic seas. Berndt et al. (p. 284 , published online 2 January) present a record of methane seepage from marine sediments off the coast of Svalb

In situ sediment temperature profile measurements provide valuable information on fluid seepage, hydrate stability, and ambient temperature of samples. We present a new instrument that can be used to obtain precisely positioned sediment temperature p

In February 2008, cruise P362/2 was undertaken aboard R/V Poseidon to the Giza and North Alex mud volcanoes (MVs) on the upper slope of the western Nile deep-sea fan. Emitted fluids were strongly depleted in chloride and rich in hydrocarbons, predomi
