BIOSIS COPYRIGHT: BIOL ABS. To optimize experimental protocol for marine dissolved organic carbon (DOC) studies in laboratory conditions, we examined the potential DOC releases from filters of different qualities as well as those from different types of bottles during 10 day-storage of Milli-Q water and 0.2 mum-filtered seawater. The results showed that utilization of 47-mm circle filters including polycarbonate (0.2 and 1 mum-pore size), polytetrafluoroethylene (PTFE: 0.5 mum-pore size) and aluminum oxide (0.2 and 0.02 mu ge (15?C, in the dark) of Milli-Q water and 0.2 mum-filtered seawater (250 ml) into 1 l-polyethylene, polycarbonate and perfluoalkoxy (PFA)-Teflon bottles, initially cleaned with HCl 1% and abondantly rinsed with copious amounts of Milli-Q water as well as in precombusted glass bottles (450?C, 6 h) induced very low DOC contamination of the solutions (0-5 muM C). Although complete DOC-free contamination experiment is difficult to reach particularly in shipboard conditions, these r
