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: The eGEOTRACES Electronic Atlas is the visual representation of the IDP2014 data providing section plots and a new kind of animated 3D scenes that provide geographical and bathymetric context that is crucial for the interpretation and assessment of observed tracer plumes.

TL;DR: Fanning et al. as mentioned in this paper showed that during seasonal development of blooms in the Polar Frontal region, concentrations of nitrate and phosphate decreased in surface waters, which is consistent with decreasing availability of Fe for nitrate reduction, but also may be due to intrinsically low N P in Fragilariopsis kerguelensis cells.

TL;DR: In this article, an unprecedented number of 666 samples was analyzed for 44 stations along 5 ocean transects. The results showed that dissolved Al concentration in surface layer water (SLW) was very low, close to 1 nM, with the lowest SLW concentrations towards the Canadian part of the Arctic Ocean and higher values adjacent to and in the shelf seas.

TL;DR: In this paper, the authors presented deep water (>250 m) DFe concentrations of the Central Arctic Ocean (Nansen, Amundsen and Makarov Basins) with the lowest DFe concentration (0.2-0.4 nM) in the Makarov Basin, higher concentrations (similar to 0.45 nM).
