Organic Carbon Remineralization and Calcium Carbonate Production Rates in the Red Sea Computed From Oxygen and Alkalinity Utilizations Open
Organic carbon remineralization rate (OCRR) and the calcium carbonate production rate (CCPR) are influential variables on the efficiency of the biological carbon pump (BCP) but are not well understood in Red Sea. We used historical cruise …

In the Wake of Deeper Convection: Nonsteady State Anthropogenic Carbon in the Greenland Sea Open
We evaluate changes in dissolved inorganic carbon (DIC) in the Greenland Sea between 2002 and 2016, a period characterized by increasing convection depths. We find a mid‐depth maximum in anthropogenic carbon (C ant ) accumulation that occu…

Rapid fCO2 rise in the northern Barents Sea and Nansen Basin Open
Maps of surface water fugacity of CO2 (fCO2) over eastern Fram Strait, south-western Nansen Basin, and the north-western Barents Sea (73-84°N, 5-46°E) from September 1997 to December 2020 were made and used to investigate seasonal and temp…

Assurance offshore CO2 monitoring, a cross-disciplinary approach. Open
Formulating appropriate monitoring programs for offshore geological CO2 storage projects, from either a regulatory or operator viewpoint, is difficult to achieve without a properly quantified cost-benefit analysis of what that monitoring c…

Acidification of the Nordic Seas Open
Due to low calcium carbonate saturation states, and winter mixing that brings anthropogenic carbon to the deep ocean, the Nordic Seas and their cold-water corals are vulnerable to ocean acidification. Here, we present a detailed investigat…

Suitability analysis and revised strategies for marine environmental carbon capture and storage (CCS) monitoring Open
Environmental monitoring of offshore Carbon Capture and Storage (CCS) complexes requires robust methodologies and cost-effective tools to detect, attribute and quantify CO2 leakage in the unlikely event it occurs from a sub-seafloor reserv…

Sea surface pCO2 variability and air-sea CO2 exchange in the coastal Sudanese Red Sea Open
The dynamics of sea surface pCO2 () and air-sea CO2 exchange of the Sudanese coastal Red Sea has for the first time been studied over a full annual cycle (October 2014 - October 2015) based on semi-continuous measurements from moored auton…
Detection and quantification of CO2 seepage in seawater using the stoichiometric Cseep method: Results from a recent subsea CO2 release experiment in the North Sea Open
Carbon Capture and Storage (CCS) is a potential significant mitigation strategy to combat climate change and ocean acidification. The technology is well understood but its current implementation must be scaled up nearly by a hundredfold to…

Nordic Seas Acidification Open
Being windows to the deep ocean, the Nordic Seas play an important role in transferring anthropogenic carbon, and thus ocean acidification, to the abyss. Due to its location in high latitudes, it is further more sensitive to acidification …

Trends of Ocean Acidification and <i>p</i>CO<sub>2</sub> in the Northern North Sea, 2003–2015 Open
For continental shelf regions, the long‐term trend in sea surface carbon dioxide (CO 2 ) partial pressure ( p CO 2 ) and rates of ocean acidification are not accurately known. Here, we investigate the decadal trend of observed wintertime p…
