The long-term stability of the deep ocean carbon storage feedback mechanisms across the Plio- and Pleistocene

Autor: David Naafs, Rich Pancost, Jerome Blewett, Vittoria Lauretano, Jens Hefter, Simon Pounton, Ruediger Stein, Gerald Haug

Storing carbon in the deep ocean is a key-feedback mechanism that allows astronomical forcing to drive the late Pleistocene glacial/interglacial variations. As carbon storage is intrinsically linked to oxygenation, proxies for sediment oxygenation ha

Peatlands are impacted by climate and land-use changes, with feedback to warming by acting as either sources or sinks of carbon. Expert elicitation combined with literature review reveals key drivers of change that alter peatland carbon dynamics, wit

Summary Bacteria play key roles in the carbon cycle. In many sediments and peatlands, methanotrophic bacteria consume a portion of released methane, reducing the emissions of this potent greenhouse gas. In marine oxygen minimum zones (OMZ) and other
