This report reviews and provides a preliminary interpretation
of recent observations made by CalCOFI
(California Cooperative Oceanic Fisheries Investigations)
and other programs sampling the coastal waters of the
Californias. Since this is a continuation of a series of annual
reports, the emphasis here is upon observations
made during the past 18 months, but longer-term trends
must also be considered. The major change in oceanographic
structure in the past year was the transition from
strong El Niiio conditions in early 1998 to cool-water,
La Nilia conditions in early 1999. Ecosystem structure
also showed large changes during this period. Phytoplankton
abundance during 1998, as indlcated by chlorophyll
concentration, was typical of the values seen during
the last decade, but it appeared to be increasing in early
1999 in association with the transition to cool-water
conditions.
