Given the current worldwide situation caused by COVID-19, the first deadline for the submission of datasets to GDAC (or national data centres for US, Dutch and French PIs) using DOoR templates and intercalibration reports via DOoR to guarantee inclusion in IDP2021 is extended to the 15th of May 2020. Please find below the initial announcement […]
Following from the release of two intermediate data products in 2014 and 2017, the GEOTRACES Data Management Committee is pleased to announce the planned release of the third intermediate data product in July 2021 (IDP2021). For GEOTRACES principal investigators (PIs) with data to include in IDP2021, we remind you that you need to (1) submit […]
Timothy Kenna and Margie Turrin from Columbia University, New York, have made available a new set of educational materials in English and Spanish for developing science literacy in students. They have produced three educational activities which all have a focus on understanding radioactivity in the environment. The first is a lab designed to introduce the […]
The 2nd Russian GEOTRACES seminar was held on February 7, 2020 in Moscow at the Shirshov Institute of Oceanology, Russian Academy of Sciences (https://ocean.ru). Prof. Dr. Eric Achterberg initiated the GEOTRACES seminar during his visit as part of the Helmholtz team. About 50 people attended the seminar in Moscow and some people listened to the […]
SWINGS is a multidisciplinary 4-year project fully dedicated to elucidate trace element sources, transformations and sinks along a section crossing key areas of the Southern Ocean (SO). SWINGS aims at 1) establishing the relative importance of sedimentary, atmospheric and hydrothermal sources of trace elements and isotopes (TEIs) in the Indian sector of the SO, 2) […]

A complete review of published and new water column profiles of 230Th and 231Pa concentrations and neodymium (Nd) isotopic compositions collected in the Amerasian Basin of the Arctic Ocean between 1983 and 2015 was performed by Grenier and co-workers (2019, see reference below). This review allowed them to identify regional and temporal variability of geochemical […]
The UNEP Minamata Convention was ratified in August 2017 and aims to protect human health from mercury exposure by reducing anthropogenic, inorganic, mercury emissions. The most toxic and biomagnifying mercury species, methylmercury, is not emitted from anthropogenic or natural sources, but produced in the ocean from inorganic mercury. Marine mercury methylation has been confirmed for […]
Three GEOTRACES Japanese cruises on board the R/V Hakuho Maru allowed establishing basin-scale and full-depth sectional distributions of total dissolvable iron (tdFe), dissolved iron (dFe), and labile particulate iron (lpFe=tdFe – dFe) in the North Pacific Ocean. Zheng and Sohrin (2019, see reference below) also discuss aluminum (Al) and manganese (Mn) data in this work. […]
