Title:  Dissolved Organic Matter in the Ocean Carbon Cycle

Dennis A. Hansell, University of Miami

Time and Location: 10:30 Wednesday, room 310.

Abstract: Twenty-five years ago, dissolved organic matter (DOM) held modest interest to the ocean science community;
the few measurements reported suggested a huge yet relatively quiescent pool.  As the ocean carbon cycle emerged as a
major uncertainty though, and our ignorance of DOM was highlighted, biogeochemical considerations of the pool gained a
momentum that continues today. Misdirections were common at that restart as our understanding of DOM's dynamics was
flawed, costing several years and great investment to overcome.   This presentation tells the story of complacency,
false starts, determination and compelling advances in this burgeoning discipline.
