"I am really excited about these articles from our North Pacific GEOTRACES work, which was the first NSF funding I received after arriving at CMS. Our studies target the cycling of trace metals in the region of oldest ocean waters, and answer questions I have been puzzling over for years - some of which have been around since before I was born! We knock down the idea that oxygen minimum zones are places where metals precipitate, and we show that particle-scavenging is needed to complete our understanding of the global zinc cycle." –Tim Conway, Associate Professor.
