Nutrient-OMICS coupling approach reveals unexpected actors for atmospheric carbon sequestration
Sharma and colleagues investigated the role of clay minerals in strengthening the marine biological pump.
Sharma and colleagues investigated the role of clay minerals in strengthening the marine biological pump.
Shelley and co-authors propose an extensive coverage of the distribution and fate of the lithogenic and anthropogenic aerosols over the Mediterranean and Black Seas.
Authors present a comprehensive review of iron and iron isotope sources, internal cycling, and sinks in the ocean.
A suite of trace element was measured in aerosols collected in the North and equatorial Pacific.
Xu and Weber developed a data-assimilation model of the aluminum oceanic cycle.
This study suggests that volcanic emission can represent a significant source of bioavailable iron to open ocean anaemic ecosystems.
Using measurements of dissolved and particulate thorium-230 and thorium-232 along a section across the South Pacific, authors estimated the dust flux over this remote area
A recently developed method based on the natural radionuclide beryllium-7 has provided a means to estimate the bulk atmospheric trace element deposition velocity
Conway and co-authors (2019, see reference below) present the first evidence that anthropogenic iron (Fe) from combustion sources is visible at the basin scale, using iron isotopic composition (δ56Fe) analysis […]
Atmospheric dust is considered an important source of trace elements to the ocean. As part of the Eastern Pacific Zonal Transect GEOTRACES cruise (EPZT GP16), Buck and co-workers collected 17 […]
Dust particles settling into the surface of open ocean environments are for years assumed to provide nutrients to these distant nutrient-limited areas. Torfstein and Kienast (2018, see reference below) present […]
Alex Baker and Tim Jickells (2017, see reference below) propose to answer to this question thanks to analysis of aerosols collected in the framework of the Atlantic Meridional Transect (AMT). […]
Shelley and co-workers (2016, see reference below) established that atmospheric deposition of trace elements was low throughout May-June 2014 along the GEOVIDE (GA01) cruise track in the North Atlantic Ocean. […]
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 […]
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) […]
Scientists participating in GEOTRACES have developed a new strategy to evaluate trace element fluxes to the ocean from aerosols (Hsieh et al, 2011). The new approach uses the common geochemical behaviour […]
