TL;DR: In this article, the vertical distributions and horizontal surface transects of dissolved and particulate Al at several locations in the Pacific Ocean are presented, and it is shown that the primary source of dissolved Al to the surface waters of the central Pacific is from eolian input.

TL;DR: The GEOTRACES project as mentioned in this paper has been developed as a result of community input to study the global marine biogeochemical cycles of trace elements and their isotopes, which can be combined with new modelling strategies that have evolved from the WOCE and Joint Global Ocean Flux Study (JGOFS) programs.

TL;DR: In this article, the vertical distribution and inter-ocean fractionation of aluminium can be explained by geographical variations in atmospheric aluminium sources, intense particle scavenging throughout the water column, and some regeneration in bottom waters.

TL;DR: In this article, the authors present measurements of titanium profiles in the open ocean and find that dissolved titanium is a reactive short-residence-time element, with a unique and highly non-uniform spatial distribution.

TL;DR: Dissolved Ga concentrations in the Pacific Ocean range from 2 to 30 picomolar: they are low in surface waters (2-12 pM), with a subsurface maximum at 150-300 m (6-17 pM) and increasing values with depth to a maximum in bottom waters (12-30 pM). The highest concentrations are in the central gyre, with lower values toward the north and east where productivity and particle scavenging increase as discussed by the authors.
