Notices

DEEP DIVING CRICKET - Last year, Elton Williams of Louisiana, saw a
newspaper story on Kevin Hardy's mouse house habitat project in his local
newspaper. Elton was jazzed because he was stumped as to what to do for
his science fair project. Elton contacted Kevin who helped him with
everything he needed. Recently, Elton wrote a thank you note that said,
"Dear Mr. Hardy, I want to thank you for the information. I put a cricket
underwater for three days, and it survived! I won first place in my
category. Thank you again!"

SIO ELECTION RESULTS - Michael Buckingham has been elected Chair of the SIO
Faculty, effective September 1, 2000, through August 31, 2001. Miriam
Kastner has been elected Vice Chair of the SIO Faculty, effective
September 1, 2000, through August 31, 2001. Horst Felbeck and Robert
Shadwick have been elected members of the SIO Faculty Executive Committee
and of the Representative Assembly of the UCSD Academic Senate, effective
September 1, 2000, through August 31, 2002. Jim Hawkins and Detlef Stammer
have been elected as their respective alternates. (Art Yayanos, SIO
Faculty Chair)

MORE LITTLE FUTURE SCIENTISTS - Joseph (SIO Carpenter Shop) and Rhonda Han
have a new baby girl. Rachel was born on 10/23, weighed 7lbs, 4oz, and
was 19 inches long. She was obviously very eager to get out into the
world, because little Rachel and born 2 weeks early. Everybody's just
fine & dandy!

Ship News

R/V Roger Revelle, Weekly Scientific Report, 19 October 2000:We occupied
the French Frigate Shoals stations a second time, near sprint tides this
time, but did not find large increases in the mixing compared to our
earlier occupations, near neap tides. After finishing them we moved to a
site west of Nihoa, which Merrifield and Holliway predict to be the third
source of internal tides on the ridge. We are doing 3 stations, each for
about 25 hours. One consisted of repeated lines coming over the steep
slope onto the crest. We found intense and highly sheared flows below the
crest which produced an average diapycnal diffusivity of 10^-2 m^2/s over a
section 100 m thick. It appeared to turn on when predicted surface tides
were southward over the ridge crest. Having just finished a second station
25 nm south of the ridge, we are proceeding to a third station 50 nm south
of the ridge. (Mike Gregg/UW)

R/V Melville, Weekly Scientific Report, 24 October 2000: We have arrived at
our first survey area (Bauer Scarp) and are illuminating the scarp using
SeaBeam, magnetics and gravity. The SeaBeam system is working well and we
are obtaining excellent bathymetry of the scarp and associated structures.
A new automated tracking system on the bridge has proved most useful for
SeaBeam surveying - keeping Melville within 3-4 meters of our planned ship
track and minimizing overlaps or gaps in swath coverage. The morphology of
the scarp is distinct from similar rift-margin escarpments (i.e. Henry and
Hudson troughs in the far south Pacific); having little or no discernible
flank-uplift, significant variability in scarp relief and trough depth, and
a pronounced slope up to younger post-rift crust. We have also
successfully deployed two oceanographic floats (1 ARGOS, 1 SOLO) while in
transit to the scarp (see the Oct. issue of Natl. Geogr.). The survey area
appears to be a prime fishing ground as well, and the bridge has been quite
vigilant in avoiding the fishing fleet. (B. Eakins, UCSD)

R/V Roger Revelle, NEMO04RV Weekly Scientific Report, 26 October 2000:
After finishing our stations at Nihoa we moved to the Kauai Channel and
began by running sections across the Kaena Point ridge, close to shore
where depths were as shallow as 300 m. Difficult to work there owing to
strong jet along ridge, but we observed displacements of isotherms with the
tidal cycle, one showing a wave with the width of the ridge as the
half-wavelength. Strong turbulence over the ridge which decayed to the
south in nearly the same manner as observed at Nihoa and French Frigate
Shoals. One more station in channel tomorrow, in zone predicted to be free
of M2 waves from ridge. Then will spend a few days observing sections
close to shore at Barber's Point and Mamala Bay. Our objective is to
examine the structure of a trapped internal tide tentatively described
several years ago by Peter Hamilton of SAIC. Will finish with time series
over Penguin Bank, off Molokai. Bottom boundary there is predicted to
produce all BBL dissipation for entire Hawaiian Ridge. The crew and
facilities on Revelle have been a dream to work with -- hats off to them
and the sio marfac. (Mike Gregg/UW)

CalCOFI 0010NH Scientific Report 23 Oct 2000 We have just finished station
83.110 after losing 24hrs to continual atypical October weather. Winds to
50kts and 20+ft seas finally dissipated after transiting around sta 87.90
for 24hrs. The MOCNESS net, which sat exposed on the fantail, received
some damage from the large amount of water that cascaded on board. The
stanchions are bent beyond usability and we will not attempt to straighten
them at sea. The slide bars on both sides of the net were also bent, but
have been straightened using a technique stolen from a Jackie Chan movie
(Shanghai Noon) viewed on board. Further MOCNESS deployments will be from
a recumbent position. The ADCP also experienced an equipment failure.
After several resuscitation attempts, replacement parts and a computer
were picked up at Dana Point during a personnel exchange. Repairs were
done shortly thereafter and it is back online. Continued comparisons of
the temperature data to the 50yr mean show only small pockets of
anomalously colder and warmer water, indicating typical conditions for
this time of year. The chlorophyll maximum continues to be deep and very
small. Zooplankton biomass has been unusually low even for a fall CalCOFI.
Bird and marine mammal observations have been interesting. On the 18th,
large numbers of Common Dolphins streamed by throughout the afternoon and
evening. A Humpback whale was also seen. Black-vented Shearwaters were a
dominant species in the nearshore waters and were observed in feeding
flocks numbering over 100. A Minke whale was seen on the 19th. It was a
surprise to wake to the sound of birds calling while at station 87.45 off
the Channel Islands. Thirteen species were tallied once the sun had risen.
Dr Timothy Nightingale's skin sea surface measurements continue and,
thankfully, with the clearer skies his RAL SISTer radiometer readings have
improved significantly. Fishing on lines 90 & 87 has been unsuccessful
except for a single 40lb albacore caught this morning upon arrival to prodo
sta 87.110. With the break in weather, the morale of crew and scientific
party has improved. We can finally appreciate the great meals being served.
Unfortunately, the weather forecast for mid-week is gale force winds again.
We hope the weatherman is wrong.
