TL;DR: The GEOTRACES Intermediate Data Product 2017 (IDP2017) as discussed by the authors is the second publicly available data product of the international GEOTrACES programme, and contains data measured and quality controlled before the end of 2016.

TL;DR: In this article, a column extraction method using the DDQ resin was applied to sea water analysis with satisfactory results being obtained, and its extraction behavior was studied and compared with solvent extraction with DDQ for Aq, Al, Bi, Cd, Cu, Fe, Ga, Mn, Ni, Pb, and Ti.

TL;DR: Tungsten depth profiles in oceanic waters have been analyzed in this article, showing that tungsten is removed from seawater much more rapidly than molybdenum, by adsorption onto ferric hydroxide, manganese oxide and clay minerals.

TL;DR: In this paper, the authors present evidence for strong hydrothermal activity in the eastern Manus Basin (depth: 1700-2100 m), the existence of large scale triple-layered buoyant plumes at depths of ∼1100 m (shallow plume), ∼ 1700 m (deep plume) and ∼1400 m (middle plume with less extent than the other two plumes) that were revealed from water column anomalies of CH 4, Mn, Al and pH observed in November to December 1990.

TL;DR: In this article, a column packed with macroporous polystyrene-divinylbenzene resin after complexation with quinolin-8-ol was used for the determination of chromium(III) and chromium-VI in sea water by graphite furnace AAS.
