Intercalibration

Welcome to the first Korean participation in GEOTRACES

Thanks to the newly launched research vessel (R/V) Isabu of the Korea Institute of Ocean Science and Technology (KIOST), and the acquisition of a contamination-free PRISTINE (NIOZ, NL) ultraclean seawater sampling system for trace elements, the Korean marine geochemists are pleased to published their first reliable trace metal (TM) results. Two cruises conducted in the Indian Ocean […]

GEOTRACES intercalibration of the stable silicon isotope composition of dissolved silicic acid in seawater

Dissolved silicon (Si) is a major oceanic nutrient and variations of its stable isotope values are reflecting the intensity of surface primary production. As for other isotopes, agreement between the different laboratories is crucial. Here, the first intercalibration study of the stable silicon (Si) isotopes in seawater (δ30Si(OH)4) is presented as a contribution to the […]

GEOTRACES: Get the right data!

Measuring concentrations of many constituents at the nano- to picomolar levels in seawater is a difficult challenge, requiring thorough intercalibration between the different laboratories participating to the same programme. GEOTRACES is but one example of a programme that has intercalibration as an essential component of its field-based efforts. The standing GEOTRACES Standards and Intercalibration Committee (S&I) […]
