Machine learning approach led to the first iron climatology
Huang and co-workers propose the first data-driven surface-to-seafloor dissolved iron climatology.
Data Compilation
Updated compilation of the global continental and marine lithogenic neodymium isotopic measurements
This new compilation and gridded datasets offer a concrete way forward to improve the application of neodymium isotopes as a useful tracer of ocean circulation.
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.
New BioGEOTRACES data sets: Connecting pieces of the microbial biogeochemical puzzle
Microorganisms play a central role in the transfer of matter and energy in the marine food web. Microbes depend on micronutrients (e.g. iron, cobalt, zinc, and a host of other […]
52 years of Benthic Nepheloid Layer data!
A data base of 2412 profiles collected using the Lamont Thorndike nephelometer from 1964 to 1984 is used to globally map turbid nepheloid layers by Gardner and co-workers (2018, see […]
Particle distribution in repeated ocean sections and sediment resuspension
This is the first compilation of an expansive data base of transmissometer data on a decadal period of time. More than 7376 stations have been analyzed for “cp” value, a […]
Benthic nepheloid layer global compilation: an invaluable resource for GEOTRACES researchers
Models simulating any oceanic tracer biogeochemistry require a good depiction of the particle distribution, key to incorporating properly scavenging-remineralization processes. However, this kind of description is still rare. Gardner and co-workers […]
What is generating the benthic nepheloid layers?
How ubiquitous, variable or persistent are nepheloid layers? What is the main process generating these “clouds at the bottom of the sea”? Gardner and co-workers (2017, see reference below) explore […]
GEOTRACES publishes the motivations and description of its first Intermediate Data Product
GEOTRACES proposes an article that describes its first integrated and quality controlled Intermediate Data Product 2014 (IDP2014): the digital data package and the eGEOTRACES electronic Atlas that provides section plots and […]
GEOTRACES: Changing the way we explore ocean chemistry
Read about the experiences and lessons learned in the planning and implementation of GEOTRACES international programme in a recent paper published in Oceanography. Anderson and co-authors present an extraordinary synthesis of […]
Trace metals in deep ocean waters: A review
A synthesis on the data available on the distribution of selected trace metals (i.e. Cadmium, Cobalt, Copper, Molybdenum, Nickel, Lead and Zinc) in the deep ocean from 1979 to 2009 […]
A global compilation of the neodymium isotopic composition of seawater for GEOTRACES
GEOTRACES will allow the collection of numerous data that will be archived in the GEOTRACES Data Assembly Centre (GDAC), and will eventually contribute to create a world atlas of tracers […]
