Wayland Vaughan Hall (formerly Endurance Hall) at 3 p.m. We are fortunate to have Vaughan's granddaughters, Delia Laitin & Dorothy Carlsten, as our guests and we hope you all will join us that day. If the weather is nice, the event will be held at the north end of the building across from the Old Director's House (Sea Grant). If the weather turns cool, the festivities will be held in the atrium of the building. As always, a yummy reception to follow!

Gang, it's almost time for The Umpteenth SIO Holiday Party, Friday, December 21, 5 p.m., at Birch Aquarium! Yet another amazing and fun filled Holiday Party! This year we will have the terrific oldies band "Hot Rod Lincoln." Child care is provided in the aquarium classroom (so the adults can dance, too!). Oh boy, oh boy! (Jill Hammons, x43948) Ship News Melville Weekly Scientific Report - A midwater trawl over the Horizon Deep lasted over 17 hours with 9800 meters of wire out. The catch was modest in size and consisted of a diverse group of organisms including some peculiar (at least to us) fish. Two free vehicle traps, one on the sea floor and the other 2.5 meters above it, were set at 10,770 meters. The first caught only a single species of amphipod whereas the other caught two species. The multicorer was deployed to 10,158 meters and was recovered with excellent cores. Unlike the Kermadec Trench sediment samples where worms were apparent, the Horizon Deep sediment samples did not have any easily seen macroscopic organisms. We are indebted to Resident Technician Tammy Baiz for her expertise at multicoring to possibly record depths. Sea Beam displays, made possible for us by Computer Technician Jim Charters, of the sea floor of the Tonga Trench are spectacular to view. These varied benthic habitats present fascinating opportunities for future study. We selected three neighboring habitats for sampling with free vehicle traps at depths of 6,834, 7,249 and 8,723 meters. Although we trapped only amphipods, the mix of species was different at each of the sites. Fifty nine pressure vessels now contain a variety of samples at pressures as high as 109 MPa for cultivation of microorganisms at SIO. Two SOLO floats were deployed this week as we headed north. Over 40 net tows have been completed for studies of copepod population biology and molecular phylogeny. Only superlatives are appropriate for describing this memorable trip. I end this weekly report as I began the first one with my sincere gratitude for the assistance of Captain David Murline and his crew and of the resident and computer technicians. They provided exceptionally generous assistance to our scientific program. (Art Yayanos, Leg 14 of Cook Expedition) FLIP - Week four of the HOME FarField cruise has been both pleasant and productive. We've collected another 2500 CTD-micro Conductivity profiles (to 800m)with accompanying shear, velocity and acoustic scattering strength information. The upper 300m of the thermocline has been fairly quiet this week, but at depth conditions have remained active.The low-mode semi-diurnal motions that followed last week's spring tide initially gave way to six hour period waves. Now a broad mix of frequencies and modes is passing by. The thermocline appears quite intrusive below 300m. Whether this is the aftermath of local mixing or just a coincidence remains to be seen. After a fairly moderate month, winds yesterday kicked up into the 20-30 kt range. eas built rapidly. Our wave staff recorded a few 9 m crest-to trough waves. Conditions have moderated somewhat, today. FLIP will return to Pearl Harbor about 10 November. ( Rob Pinkel, MPL) Revelle Weekly Science Report - Today (Tues 10/30) is the final day of at sea operations of the DRIFT Leg 05 after nearly four weeks at sea. We are currently multi-beam mapping along a few remaining tracks within our study area offshore Lima, Peru. During the leg, we have established two seafloor geodetic sites on the continental slope of the South American plate. At each site we have completed nearly a week of combined deep-towed and shipboard measurements to determine the centimeter location of the seafloor monuments. Thanks to Captain Curl, Chief Mauricio, and Restech Shad Baiz for all their efforts. All (including four new shellbacks) are looking forward to the port stop.
