During the cold subduction and exhumation of the oceanic crust: When the oceanic crust subducted to ∼50 km, the carbon species in the fluids were dominated by reduced CH 4, and its proportion is ...

Our results suggest that the local (and likely global) carbon biomass of Aulosphaeridae, and probably the large Rhizaria overall, needs to be revised downwards, but that these organisms nevertheless ...

Trehu is a seismologist who has studied the Cascadia Subduction Zone for years. In 2021, a research vessel went from Vancouver Island to the Oregon-California border to gather data.

Scientific ocean drilling discovers dynamic carbon cycling in the ultra-deep-water Japan Trench Date: September 11, 2023 Source: MARUM - Center for Marine Environmental Sciences, University of Bremen ...

A megasplay fault branches upward from the subduction zone, and in the event of "The Big One," would raise the seafloor, displacing a massive amount of water closer to the coast.

It’s the 323rd anniversary of the last Cascadia Subduction Zone earthquake.We spend a fair amount of time thinking about the ‘Big One’ (and the ‘Really Big One’) in the Pacific Northwest.

The Cascadia Subduction Zone looks a little different than researchers thought. Here's what that means for 'The Big One' Although the hazards may be different, that does not mean the risk is less ...
