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 […]
