摘要：
This report is primarily concerned with high-temperature DOC measurements and associated analytical problems, and secondarily with wet chemical/UV DOC determinations and high-temperature DON analysis. Included are results on: (1) preservation of non-frozen/frozen and non-acidified/acidified seawater samples; (2) use of alternative catalysts to the Sumika 3% Pt/Al2O3 (used by Y. Suzuki, Sumika Chemical Analysis Services, Osaka, Japan) for high temperature DOC/DON combustion; (3) DOC-high temperature (DOC-HT) and DOC-ultraviolet (DOC-UV) profiles for the north central Pacific (NCP) gyre and Sargasso Sea (SS) as measured by Y. Suzuki and at Scripps Institution of Oceanography (SIO); (4) increased oxidation of DOC with S2O82-/UV by Cl- complexation with Hg2+; (5) evaluation of the contribution of small particles and/or colloids to DOC as measured by filtration through 0.2 and 0.02 mum pore-diameter Anopore(R) filters.
