§The two Pseudocalanus spp. likely
have distinct patterns of transport,
retention, and maintenance on Georges Bank.
§There were distinct
source regions for the two
species in both 1997 and
1999. By June, the species’
distributions were overlapping on the crest of the Bank.
§Based on total
Bank-wide abundance, the spring
evolution
of abundance of the two species was similar, with earlier
build-up for P. newmani.
§The spring evolution
of abundance of the two species differed among five regions of Georges Bank, with the exception of the Northeast peak.
§Vertical distributions of the
two species differed both Bank-wide and within each region, with P. moultoni less abundant in the top 15 m.
