Fig. 1. Mesozooplankton biomass (mg C m 3 ) in the upper 150 m water column along Line P during 4 cruises in 1996 and Error bars are 1 standard deviation calculated from 3 net hauls. Refer to map in Whitney and Freeland (1999) for station locations. Biomass samples were not collected at stations and times with no associated biomass bar.Whitney and Freeland (1999)
Fig. 3. Neocalanus plumchrus vertical distribution and stage structure at OSP during winter, spring, and summer, day and night. No N. plumchrus were present at station P04 during periods sampled.
