Terra Nova, 24, 255–272, 2012 Abstract Cold seep systems comprise three structural
elements: source, plumbing system, and venting structures or seeping features at or near 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 …

There is growing concern about the transfer of methane originating from water bodies to the
atmosphere. Methane from sediments can reach the atmosphere directly via bubbles or …

A mud volcano area in the deep waters (> 2000m) of the Black Sea was studied by
hydroacoustic measurements during several cruises between January 2002 and June 2004 …

Accurately quantifying the amount of naturally occurring gas hydrate in marine and
permafrost environments is important for assessing its resource potential and understanding …

A global dataset of molecular and stable isotope compositions of gases released from 209
different specimens of natural gas hydrate is presented and discussed. The 26 hydrate …

This study quantifies the excess pore pressure resulting from gas hydrate dissociation in
marine sediments. The excess pore pressure in confined pore spaces can be up to several …

The Dnepr paleo-delta area in the NW Black Sea is characterized by an abundant presence
of methane seeps. During the expeditions of May–June 2003 and 2004 within the EU …

In this paper, we present the current practice of investigations of seafloor instabilities and
deformation processes, based on extensive research conducted over the last years, which …

Mud volcanoes sometimes erupt within days after nearby earthquakes. The number of such
nearly coincident events is larger than would be expected by chance and the eruptions are …
