UCSD 40TH ANNIVERSARY - UCSD is celebrating its 40th anniversary with a
year-long series of special events. UCSD will demonstrate the years of
growth in quality, strength, and breadth since Roger Revelle, considered
the "father" of UCSD, envisioned an educational and research mecca rising
from a dusty La Jolla mesa. A major focus of the celebration will 40
"gifts" of service to the communities of San Diego County. In a variety of
ways, the campus will feature more than 300 activities and programs that
UCSD currently provides throughout the area. For more info, visit the Web
site: http://ucsdnews.ucsd.edu/calendar/40th/default.asp.(Scripps

LAST CHANCE - You've got a two-week extension of the deadline for Other
Works. Final deadline is FRIDAY, OCTOBER 27. Any faculty or staff member
who had an article, book, or similar document published during fiscal 2000
(July 1, 1999 - June 30, 2000) which is NOT appropriate for the SIO
Contributions, please send a copy of that publication to Technical
Publications, 0233, by the deadline. These citations will be listed in the
"Other Works" section of the 2000 Annual Report. (Nan Criqui,
ncriqui@ucsd.edu,  x41295)

HAUNTED PIER - All are invited for a hauntingly good time on Scripps Pier,
Sunday, Oct. 29, 6:00-9:00 p.m.  Trick or Treat your way down the pier
while listening to spooky tales of pirates, ships lost at sea, and other
ghostly and ghastly maritime stories.  Interact with Scripps's own mad
scientists, marine monsters of the deep, and animals that glow in the dark.
Also, find out why some animals are considered "ghosts" of the sea.   Don't
forget to enter our marine-themed costume contest starting at 7 p.m!
Shuttle service to the Pier will be provided from the Birch Aquarium
parking lot.  Fee for Haunted Pier is $8, and is open to all ages.  Advance
registration is required.  For registration or more information, please
call the Birch Aquarium at Scripps at 858/534-7336.  (SIO Communications,

TRICK OR TREAT! - All buoys and ghouls and their parents are invited to the
second annual Halloween Party for SIO Kids, on Tuesday, October 31. Creep
on down to the grassy area beside the Snack Bar at 4 p.m.  and enjoy goblin
goodies and bewitching prizes for the best kids' costumes. (Sharon Franks,

Ship News

R/V Roger Revelle, Weekly Scientific Report, 10/13/00: After leaving
Honolulu a week ago, we proceeded directly out the Hawaiian Ridge to French
Frigate Shoals and chose four sites to sample microstructure and shear.  We
have occupied all stations once, each for 25 hours, two cycles of the
twice-daily tide.  The stations are: on the Ridge crest, over it's southern
flank, 15 nm offshore, and 50 nm offshore.  Strong trade winds are limiting
our sampling to the upper 800 m much of the time. Mixing within 15 nm of
the Ridge is 10-100 times open ocean background levels throughout most of
the upper 800, with the larger levels near the bottoms of our profiles.
Consistent with the elevated mixing, strain spectra are also well above
GM76 near the ridge, but relax to it at the station 50 miles from the
crest.  Shear spectra are also elevated, but do not seem to decay offshore,
so we are studying them carefully. After 2 and a half more days here, we
will head for Nihoa, to occupy some stations where barotropic-to-baroclinic
conversion is not predicted to be strong.   (Mike Gregg/UW)

R/V Melville, Weekly Scientific Report, 17 October 2000: We departed Arica,
Chile on Monday afternoon, Oct. 16th, and are heading towards our survey
region.  We have not yet received permission from Peruvian authorities to
collect marine geophysical data while transitting through their territorial
waters, therefore SeaBeam and the 3.5 kHz fathometer are offline, and the
magnetometer is stowed on deck.  We anticipate entering international
waters on Wednesday afternoon when the systems can finally be brought
online. Our research will involve SeaBeam mapping of part of the Bauer and
Anti-Bauer Scarps in the southern tropical Pacific - conjugate rift margins
formed during the capture of the Bauer microplate ~6 Ma.  We will also be
deploying six oceanographic floats as we cross the Pacific on our way to
Tahiti. I am disappointed that there are no Macintosh computers onboard for
use by scientific personnel.  Even one PowerMac would allow personnel the
ability to access Mac files that they have brought onboard. (B. Eakins,
UCSD/SIO)

CalCOFI 0010NH Scientific Report 16 Oct 2000 - Traditionally, the October
CalCOFI has been known for good weather and calm seas. This cruise has
started off by breaking tradition. After two clear days, our station work
has been hampered by heavy seas. Fortunately, the New Horizon's speed and
able crew have kept us on schedule. After a few minor equipment problems on
the first two stations, our work has progressed into the usual routine.
Preliminary data show cooler than normal conditions off Del Mar very
nearshore but most other stations look normal when compared to the 50 year
mean temperature. The mixed layer appears deeper than normal starting at
93.50 and continuing offshore, deepening the small chlorophyll maximum.
Catherine Johnson's MOCNESS project diverted us slightly southward between
stations 93.30 & 93.35. A shallow and a deep MOCNESS tow, part of a project
examining spatial and temporal distribution of deep, dormant Calanus
pacificus, were made in San Diego Trough. In addition to deep-dwelling
Calanus pacificus, a softball-sized angler fish was collected. The RAL
SISTeR radiometer has been installed on the starboard wing of RV New
Horizon's bridge and has made nearly continuous measurements of skin sea
surface temperature since the start of the cruise. Supporting measurements
of the near-surface temperature are being recorded under way with a SOAP
trailing thermistor from the University of Southampton, and on station with
a "hard hat" thermistor from the University of Miami. This ancillary work,
conducted by Dr Timothy Nightingale of Appleton-Rutheford Laboratories
U.K., will continue throughout the cruise. Birds seen in the offshore
waters include Leach's Storm-petrel, Black Storm-petrel, Parasitic Jaeger,
and Black-footed Albatross. A higher number of Northern Fulmars have been
recorded than in either the spring or summer cruises of this year. Thus
far, only one Cook's Petrel has been seen, compared to the groups of up to
40 seen during the spring cruise. This decrease can be explained by Cook's
Petrel's breeding season, which begins in October on islands off New
Zealand. An exceptional bird was the dark phase Red-footed Boobie seen
approximately 150 miles off San Diego. A Red-tailed Tropicbird was also
recorded within that area. Fishing has been decent for the southern line: 1
yellowtail, 2 yellowfin tuna and three 30lb albacore. Although the food has
been great, the addition of fresh sushi makes the rougher weather a little
more tolerable.   (Jim Wilkinson)
