Taxonomic composition
(species and stage abundances) vary from station to station. We are looking at the value of aggregating
data by major life history stage (copepod/nauplii) and size as a way to
characterize the particle environment that larvae encounter. This is not to say that all
similarly-sized particles are the same because, for instance, they may not
all be similarly detectable or catchable.
But—here it is (next slide).
Note, we increased the length range in each size category in order to
maintain viable sample sizes—the larger the organism the fewer there are in a
sample (our pump samples have pretty small volumes, which is a trade-off for
the high vertical resolution and small mesh size (40 um).
