15 Fig. 1. Mesozooplankton biomass (mg C m 3 ) in the upper 150 m water column along Line P during 4 cruises in 1996 and 1997. 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)
