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 […]
