– Welcome to the first Korean participation in GEOTRACES
 |
|
Thanks to the newly launched research vessel Isabu of the Korea Institute of Ocean Science and Technology, KIOST, and the acquisition of a contamination-free PRISTINE ultraclean seawater sampling system, the Korean marine geochemists are pleased to published their first reliable trace metal results…

– Rare Earth distribution and pattern anomalies in the Solomon Sea
 |
|
The Solomon Sea is surrounded by high and intensively weathered islands. Its complex topography and hydrography make this area a potential source of trace elements to the waters flowing through it. Dissolved rare earth elements analysis of more than 150 samples collected in the framework of the PANDORA cruise (along GEOTRACES GP12 section) showed that…

– Icebergs; a huge but highly variable source of iron to the ocean
 |
|
Icebergs have been speculated to constitute one of the largest fluxes of iron into the polar oceans since the 1930s and thus recent increases in ice discharge around the world could potentially change iron availability in the ocean….

– Tracing water mass mixing in the Cape Basin and the restricted Angola Basin with radiogenic neodymium isotopes
 |
|
In the frame of GEOTRACES cruise GA08, Rahlf and colleagues determined seawater profiles of dissolved radiogenic neodymium isotope signatures and neodymium concentrations across the restricted western Angola Basin and along the northern Cape Basin to investigate mixing and provenance of water masses…

– 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 to compare the results of N/δ15N cycle models to a sparse set of data, Rafter and co-workers propose an original approach, based on artificial intelligence methods…..

– Successful GEOTRACES summer school held in Spain
The 2nd GEOTRACES Summer School was hosted by the International Campus of Excellence of the Sea (CEI · Mar, Cadiz, Spain) on board the Spanish school vessel ‘Intermares’. It offered a series of sampling workshops and a faculty composed of word-leading international scientists.
The summer school attracted more than a hundred applicants from all over the world. From them a total of 39 students were selected coming from countries such as: United States, India, Brazil, Germany, among 15 other nationalities…
