Anthropogenic disturbance keeps the coastal seafloor biogeochemistry in a transient state

Coastal sediments and continental shelves play a crucial role in global biogeochemistry, as they form the prime site of organic carbon burial. Bottom trawling and dredging are known to increasingly impact the coastal seafloor through relocation and homogenisation of sediments, yet little is known about the effects of such anthropogenic sediment reworking on the overall cycling of carbon and other elements within the coastal seafloor. Here, we...
