NEARLY THREE-QUARTERS of the globe is covered by oceans that humans know very little about. To tease apart the chemistry of these vast waters, marine geochemists and chemical oceanographers typically have gone to sea and collected data to profile individual trace elements and isotopes such as iron (see page 62), zinc, or lead.

But these isolated studies make figuring out the interrelated chemical nature of the oceans nearly impossible. Fueled by concerns about how . . .
