A broad range
of investigators participated in the winter 2000 Japan/East Sea cruise, executing
a suite of physical, biological, bio-optical and meteorological measurements
(summarized below). Research interests included frontal dynamics, watermass
formation, bio-optical variability, boundary layer meteorology, and thermal
and ocean color (chlorophyll) variability. Real-time access to remote sensing
and near-real time access to PALACE
float measurements allowed us to optimize sampling strategies. We anticipate
close collaboration between these research efforts as data analysis proceeds.
