Abstract This report describes the state of the California
Current System (CCS)—meteorological, physical, chemical,
and biological—from January 2003 to the spring of
2004. The area covered in this report ranges from Oregon
coastal waters to southern Baja California. Over the past
year, most physical, chemical, and biological parameters
were close to their climatological mean. Contributing
to such “normal” conditions was the absence of a La
Niña that had been expected after the previous year’s
El Niño. Noteworthy, however, are the cold and fresh
anomalies in the upper 100–200 m that have been found
over large areas of the CCS since 2002. Off Oregon
these may have been responsible for increased productivity;
off southern California these were associated with
shallower nutriclines and subsurface chlorophyll maxima
in the offshore areas. It is unclear if these anomalies
are ephemeral or related to long-term changes in ocean
climate. The effects of the hypothesized 1998 “regime
shift” on the CCS are still difficult to discern, primarily
because of other physical forcing varying on different
time scales (e.g., El Niño/Southern Oscillation,
ENSO, cycles; the “subarctic influence”; global warming).
The resolution of many of these issues requires
larger scale observations than are available now. Establishment
of the Pacific Coast Ocean Observing System
(PaCOOS) under the guidance of NOAA will be a crucial
step toward achieving that goal.
