Dissolved aluminium in the central North Pacific
TLDR
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.Abstract:
Aluminium is the most abundant metallic element in the Earth's crust (8.23% by weight)1, yet little is known about its oceanic distribution. Published data sets concerning aluminium in sea-water2 are primarily for the North Atlantic Ocean3–7. We report here that dissolved aluminium concentrations in the central North Pacific are 8–40 times lower than those at corresponding depths in the central North Atlantic, but the vertical distribution features are similar. 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. Aluminium's short oceanic residence time (estimated here as 100–200 years) leads to its marked inter-ocean fractionation, which is the reverse of that for nutrient elements such as silicon.read more

What controls dissolved iron concentrations in the world ocean
TL;DR: In this paper, the authors developed a numerical model to make quantitative predictions of dissolved iron concentrations from place to place, based on measured or estimated values of the carbon export flux, are in remarkable agreement with the observed profiles at all stations from the North Atlantic through the Southern Ocean to the North Pacific.

TL;DR: Aerosol particle samples collected from Asia and the North Pacific were analyzed to investigate the relationships among atmospheric sea salt, mineral aerosol, biogenic emissions (methanesulfonate (MSA)), and several anthropogenic substances (sulfate, nitrate, and various trace elements).
