Organic matter export rates along a North-South Pacific Ocean section: what three estimating methods tell us
Quay and his colleagues present estimates of the organic matter export rate along the GEOTRACES GP15 cruise section.

When covariance of trace metals and prokaryotic taxa are tagging water masses (Southern Indian Ocean)
Zhang and colleagues investigated the potential reciprocal links between diverse prokaryotic taxa and concentrations of trace elements.
Surprising conservativity of trace metals along a costal embayment salinity gradient
Chen and co-workers analyzed an array of trace metals together with Rare Earth Elements in a salinity gradient in the Jinhae Bay, the largest semi-enclosed bay in South Korea…
Retreat of large marine-terminating glaciers may increase iron supply to surface waters
The findings demonstrate that glacial retreat and loss of ice-shelves may potentially result in increases in dissolved iron supply to surface waters downstream of large marine terminating glaciers in future.
Compilation of dissolved organic matter (DOM) data obtained from global ocean observations from 1994 to 2020
This compilation consists of measurements of dissolved organic matter (DOM) and other chemical and hydrographic parameters obtained during the global ocean observations from 1994-01-01 to 2019-12-31.
Air-sea gas disequilibrium drove deoxygenation of the deep ice-age ocean
This study provides one of the first mechanistic explanations for Last Glacial Maximum deep ocean deoxygenation.
Arctic rivers are discharging organic matter enriched in mercury to the Labrador Sea
In the framework of GEOVIDE-GEOTRACES GA01 cruise (spring 2014), Cossa and co-workers (see reference below) measured the first high-resolution mercury (Hg) distribution pattern along a transect from Greenland to Labrador […]
The sources of the water soluble organic matter contained in the aerosols over the Atlantic ocean decoded
Organic matter is an important component of aerosols, which can absorb (or scatter) light, contributing a warming (or cooling) effect to the atmospheric radiative budget. However, this impact is tightly […]
Sinking organic matter: a major driver of the oceanic zinc cycle?
Zinc (Zn) is a marine micronutrient, important for phytoplankton and involved in biogeochemical cycling throughout the oceans. Despite the importance of this element, the processes that control the oceanic Zn […]
Results from the first US-GEOTRACES cruise in the North Atlantic
Results from the first US-GEOTRACES cruise in the North Atlantic are coming out! Andrew Wozniak and co-authors show that aerosols from European-influenced air masses (combustion influenced) have higher relative iron (Fe) […]
