22 Summary () Materials fixed in the euphotic layer were quickly transported vertically as particles. (2) Organic carbon flux decreased with depth in accordance with Martin curve. (3) Settling velocity increased with depth. () Biological activity during and July worked more efficiently for the uptake of atmospheric CO 2. (5) Opal was the most important as a ballast of particulate organic carbon. Acknowledgement Sus Honjo (WHOI) and colleagues from WHOI Tommy Dickey (UCSB) and his coworkers
