  • Methanotrophic bacteria can consume methane emitted from the ocean floor before it reaches the atmosphere. Variations in coastal currents can reduce methane oxidation in the ocean by limiting methanotroph residence time above methane seeps.

  • Giant submarine gravity flows are a key mechanism in global sediment transport, yet their properties remain enigmatic. Here, the authors reconstruct the properties of a historic giant submarine gravity flow from deposits across the seafloor.

  • There is a strong correlation between submarine slope failures and the occurrence of gas hydrates. Here, the authors use a combination of seismic data and numerical modelling to show that overpressure at the gas hydrate stability zone leads to potential destabilization of the slope and submarine landslides.

  • Seafloor pits observed in the sediments off the German North Sea coast could have been excavated by porpoises or other vertebrates, rather than by hydrocarbon release as often assumed, according to analysis of high-resolution multibeam echosounder data.
