EventRising Arctic temperatures erode coastal permafrost, releasing organic carbon into nearby marine sediments. Studies show this carbon is only partially remineralized and largely remains stored, indicating the seafloor can act as a sink for greenhouse gases that would otherwise enter the atmosphere.
Arctic marine sediments can partially remineralize organic carbon released from melting permafrost, suggesting the seabed helps lock away some of the greenhouse gases that would otherwise enter the atmosphere.
Scientists report that rising temperatures are thawing and eroding coastal permafrost, sending organic carbon into nearby marine sediments where most of it remains largely unaltered rather than rapidly releasing greenhouse gases.
