Short summary
Short summary
The land-to-ocean flux of particulate organic carbon (POC) is difficult to measure, inhibiting accurate modeling of the global carbon cycle. Here, we quantify the POC flux between one of the largest rivers on Earth (Congo) and the ocean. POC in the form of vegetation and soil is transported by episodic submarine avalanches in a 1000 km long canyon at up to 5 km water depth. The POC flux induced by avalanches is at least 3 times greater than that induced by the background flow related to tides.

Short summary
Chemical weathering of sedimentary rocks can release carbon dioxide and consume oxygen. We present a new field-based method to measure the exchange of these gases in real time, which allows us to directly compare the amount of reactants and products. By studying two sites with different rock types, we show that the chemical composition is an important factor in driving the weathering reactions. Locally, the carbon dioxide release changes alongside temperature and precipitation.

Short summary
Short summary
Direct observations indicate a decline in ocean oxygen concentration. The complexity of surface oxygen variability is linked to physical and biochemical parameters. To investigate past oxygen variability, foraminiferal I/Ca proxy must be calibrated. Here, we determine the drivers of the proxy using a database of modern samples. From our results, oxygen is the principal driver of the I/Ca proxy. We highlight its complex behaviour, while reinforcing its use for palaeoceanographic reconstructions.

Short summary
Short summary
The precise geometry and extent of Atlantic circulation changes that accompanied rapid climate changes of the last glacial period are still unknown. Here, we combine carbon isotopic records from 18 Atlantic sediment cores with numerical simulations and decompose the carbon isotopic change across a cold-to-warm transition into remineralization and circulation components. Our results show that the replacement of southern-sourced by northern-sourced water plays a dominant role below ~ 3000 m depth.

Short summary
The marine reservoir age (MRA) is the difference between the 14C age of the ocean and that of the atmosphere at a given time. In geochronology, knowing the local MRA is important to derive accurate calibrated ages for 14C-dated marine material. However, MRA values for coastal West Africa are scarce. From the 14C dating of known-age bivalves from museum collections, we calculated MRA values and populated the MRA dataset for coastal West Africa over a latitudinal transect from 33°N to 15°S.
The marine reservoir age (MRA) is the difference between the 14C age of the ocean and that of...
