CalCOFI 0104JD Scientific Report 23 Apr 2001- CalCOFI 0104JD left San
Diego on April 6th 2001 on the NOAA RV David StarrJordan. By April
7th, typical spring CalCOFI weather appeared. The weather slowed
progress but never prevented station completion. After two short
stops at Dana Point and Port Hueneme, we have completed all standard
66 CalCOFI stations successfully. We will continue the egg survey
northward. This spring's surface temperature anomaly indicates we are
in our third year of La Nina. Only a small patch of offshore surface
water around 93.90, 90.90 & 90.100 (~300 miles SW of San Diego) was
slightly warmer than the 50yr mean. At 100m, this warm packet rose
to 3degC above the 50yr mean. This is possibly the remnant of the
offshore warm core eddy mapped during the January CalCOFI. All other
stations had 10m temperatures below the 50yr mean with the coldest
areas near the coast and islands indicating spring upwelling. This
is supported by extremely high chlorophylls in these areas.
Chlorophyll measured in excess of 22mg/m^3 at stations 87.35 & 87.33
(Santa Monica Bay) and 83.42 (Santa Barbara). The CUFES egg sampler
shows a distribution of sardine eggs similar to the last three
springs. High concentrations of sardine eggs occurred between
stations .60 and .80 on all 6 CalCOFI lines, 93 to 77. Line 93,
however, recorded eggs as far inshore as station 93.35. As in years
past, peak sardine egg spawning has occurred within 12.5 - 13.5 degC
and generally near the inside and outside edges of the California
Current. Alex Curtis has been utilizing the abundance of eggs for
her work determining stage-specific sardine egg buoyancy. The rough
weather has made working with a density gradient column difficult as
the particles orbit hypnotically. To look at the distribution of
eggs from this cruise, refer to the Fisheries web site:
http:\\lasker.ucsd.edu\April2001.htm Plankton volumes in the Bongo
net samples have been relatively low for a springtime CalCOFI with
low incidence of euphuasids and copepods. However, high
concentrations of phytoplankton have been especially evident in the
Bongo and Pairovet net samples. Once again the seabird and marine
mammal life of this CalCOFI cruise has been very thrilling. In terms
of seabird species the variety has been rather large: so far we have
seen 7 species of gulls, 5 species of shearwaters, 4 species each of
petrels and alcids, 3 of jaegers, 2 species each of loons,
stormpetrels, cormorants, terns and phalaropes, and 1 species of
albatross and pelican. The most extraordinary sighting for the
seabirds was a New Zealand Shearwater. The marine mammal sightings
have not been too diverse but nonetheless very exciting. So far we
have encountered during this cruise 2 piniped species, a few large
schools of Common Dolphins in coastal areas, two schools of Pacific
White-Sided Dolphins, Dall's Porposes, Gray Whales, and the most
exciting sighting of all, Northern Rightwhale Dolphins. Our thanks
to the crew of the David Starr Jordan for getting the ship seaworthy
so quickly out of the shipyard. They are true professionals. Thanks
also for the great food and good company. JRW/DMW 23Apr2001
