Cariaco sinking POM samples

Adenosyl-BHP abundances in Vancouver Island and Black Sea total suspended particulate matter and Cariaco sinking particulate organic matter samples were analyzed to study in situ production in oxygen minimum zones. Water column suspended particulate matter samples were obtained using McLane WTS-LV (standard configuration) in situ filtration systems from Vancouver Island fjords aboard R/V Barnes in 2007 and the Black Sea aboard R/V Knorr (cruise 172/8) in 2003. Sinking particulate organic matter was sampled in sediment traps as part of the CARIACO Ocean Time-Series Program in Cariaco Basin. Adenosyl-BHPs were analyzed in trap A (275 m water depth) and trap B (455 m water depth) for 14-day opening intervals from November 1999 through April 2000 and July 2002 through October 2002.
