The Tonga arc, an iron boundary in the South West Pacific Ocean
As part of the TONGA GEOTRACES process study, Tilliette and colleagues identified high dissolved iron concentrations in the west of the Tonga arc.
Pros and cons of carbon, nitrogen and silicon as tracers of modern and paleo-productivity
Farmer and colleagues review the geochemical proxies based upon sedimentary isotope ratios of three abundant biologically mediated elements.
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.
Neural network as tools to replace oceanic data deficiencies
The importance of the cycle and speciation of nitrate and its isotopes (δ15N) in the ocean does not have to be demonstrated anymore. In an attempt to overcome the difficulty […]
Surface South Pacific ecosystems reflect the availability of the nutrients iron, nitrate and phosphate
Thanks to a high resolution section across the South Pacific (150°E-150°W, GEOTRACES GP13 cruise), Ellwood and co-workers (2018, see reference below) identify that the gradient of sources and fates of […]
Widespread nutrient co-limitation discovered on GEOTRACES cruise
Browning and co-workers (2017, see reference below) find that multiple nutrients must be supplied to stimulate phytoplankton growth on the southeast Atlantic GEOTRACES GA08 cruise. The paper has been published […]
