Abstract Particle size distributions (8-105-μm diameter), chlorophyll a, and particulate carbon
were measured off the Oregon coast during July 1973. The particle counts were transformed
to volume concentration and then subjected to characteristic vector analysis.
Ninety-two percent of the variance was accounted for by linear combinations of the first
two characteristic vectors. Two weighting factors define the proportions of the two characteristic
vectors which will, when added to the mean volume concentration curve, approximate
the actual data for each sample. Variations in the first weighting factor correspond well
with variations in total volume. Changes in the second weighting factor indicate which
segment of the size range contains the largest proportion of the particulate volume. Comparison
with temperature and salinity data indicated that the near surface water with proportionately
large volumes of particles less than 20 μm was warmer and less saline than
the surface waters with large volumes between 20 and 50 μm. High correlation with particulate
carbon and chlorophyll suggests that in both cases a large proportion of the particles
is phytoplankton.
