Palmer LTER Contribution #06

As part of the LTER 1991 austral spring cruise to define the biological,
chemical, optical and physical properties of marginal ice zone (MIZ) west of
the Antarctic Peninsula (Waters and Smith, 1993), we aimed to resolve the
mesoscale variability in phytoplankton biomass, photosynthetic potential and
community composition.  Preliminary results of three transects completed
across the  MIZ on the R/V Polar Duke are presented here.  Figure 1A and B
respectively indicate station (Sta) locations and discrete depths sampled with
a Bio-Optical Profiling System (BOPS II, Smith et al. 1992).
