Scientists Discover a Way of Forming Suspended Layers of Sediment

Katherine Kornei, Science Writer by Katherine Kornei 1 August 20232 August 2023

Laboratory experiments suggest that underwater gas eruptions—due to the venting of gas hydrates, for example—could trigger the formation of layers of suspended sediment in the ocean.
