Unraveling Environmental Forces Shaping Surface Sediment Geochemical “<i>Isodrapes</i>” in the East Asian Marginal Seas Open
As major sites of carbon burial and remineralization, continental margins are key components of the global carbon cycle. However, heterogeneous sources of organic matter (OM) and depositional environments lead to complex spatial patterns i…

The QUANTIFICATION, CHARACTERISATION, SOURCE AND FATE OF PAST AND PRESENT CARBON STORAGE IN COASTAL AND OFFSHORE SEDIMENTS FOR EFFECTIVE MARINE MANAGEMENT (QUEST) Open
Globally, continental shelf environments, and the marine sediments therein, have been recognised as having significant roles to play in the sequestration, cycling and storage of. Recently, shelf sediments have been identified as the larges…

Automatic pockmark detection in the Norwegian Channel  Open
Pockmarks are widely distributed in areas with fine-grained layered sediments. We utilised a large multibeam bathymetric dataset covering an area of c. 15,000 km2 of the Norwegian Channel (NC), the western slope and adjacent shelf outside …

Locally refined spatial predictions of marine sediment carbon stocks from legacy data Open
The recent “30 by 30” global initiative to protect 30% of the world’s land and ocean by 2030 has increased the need for marine spatial planning decisions to be grounded in locally relevant empirical evidence. Continental …

Substantial amounts of organic carbon are accumulated and stored in surface sediments of the Norwegian continental margin Open
To keep the global average temperature rise well below 2°C requires drastic emission reductions and a removal of carbon dioxide (CO2) from the atmosphere. It has been suggested that part of the CO2 removal could be achieved by nature …

Modelling mass accumulation rates and 210Pb rain rates in the Skagerrak: lateral sediment transport dominates the sediment input Open
Sediment fluxes to the seafloor govern the fate of elements and compounds in the ocean and serve as a prerequisite for research on elemental cycling, benthic processes and sediment management strategies. To quantify these fluxes over seafl…
