Oxygen minimum zones appear to be the preferential sites of dark carbon fixation.

The timescales and spatial scales become smaller, the closer you get to the shore. This naturally leads to the suggestion that we need geostationary satellites globally, capable of monitoring diurnal variations (observations at hourly time scales).

Regular interactions with ESA ocean cluster projects (and others) looking into physical variables are essential for the OCS community

We need to consider what observing capabilities/frameworks are needed to best capture and improve estimates of these C fluxes. Especially as the severity and frequency of extreme events are expected to change significantly with climate change.
