June 8 - June 15, 2001 vol. 38 no. 23 In Memoriam The San Diego Union Tribune noted last month that Garth I. Murphy died on May 5, at age 79. A Ph.D. alumnus of SIO in 1965, Murphy was the first to be appointed CalCOFI Coordinator, from 1959 to 1965 (CalCOFI began in 1948). He helped to establish fisheries restrictions on the then-declining sardines. After completing his Ph.D., Murphy was a professor of oceanography at the University of Hawaii, was a consultant to the U.N. Food and Agriculture Organization, and in 1974 became a research scientist in fisheries in Australia with CSIRO. He retired in the early 1990s and was in a nursing home in Woodland, California, (near Davis) when he died. (Betty Shor) Calendar Friday, June 8 MARINE BIOLOGY SEMINAR - Raymond T.

Dr. Berger will discuss climate change over the last thousand years, including a comparison of Northern Hemisphere change and the California Current system. He will also address a major shift in climate conditions that occurred around 800 years ago-the type of natural change that makes it extremely difficult to identify the human impact on the ocean-climate system. (The piece repeats Sunday, June 17, at 7 p.m.). UCSD-TV airs on Cox Cable Ch.76; North County Cox Cable Ch.58; Time Warner Cable Ch.18; Del Mar TV 3; or UHF (no cable) Ch. 35. For a complete program schedule, please call 534-3535. PERSPECTIVES ON OCEAN SCIENCE - Join us for Donna Blackman's lecture: "Exploring an Undersea Mountain: Tectonic Plate Spreading and Hydrothermal Vents of the Mid-Atlantic Ridge" 7:30-9:00 a.m. in the Birch Aquarium Galleria. Join Dr. Blackman for a fascinating overview of tectonic plate spreading and the progress she and her colleagues have made in this area of research--as well as the discovery of the "Lost City" hydrothermal vents. Through slides and video captured by her team aboard the research submersible Alvin, participants will get a glimpse of this unique deep-sea environment and discover the importance of seafloor exploration and the discovery of previously unknown biological communities. Please RSVP to 534-7336. Includes continental breakfast, parking validation, and aquarium admission for the day. Members: Free; Guests: $8; UCSD/Scripps staff, faculty, and students: $5. Friday, June 15 BOB LUM'S GOLF FIESTA - Four p.m. is the tee-off time for Bob Lum's retirement party, Friday, June 15. Don't get caught in a sand trap!

(Jill Ives, x43848) MARK YOUR CALENDARS - The Umpteenth SIO Beach Picnic will be held on Saturday, August 18, on the beach north of the SIO Pier. Bring the kids! Ship News Week 1 Activity Report for New Horizon Cruise NH-01-12 (May 27-June 3) From: Tim Eglinton (Chief Scientist) - The overall objective of this cruise is to collect surficial continental margin sediments for organic geochemical and isotopic studies. Sampling sites were selected in order to provide a range of depositional environments (river-influenced, oxic/suboxic, shelf/slope/rise/abyssal plain). On the first day of the cruise we deployed a multicorer (MC) and giant gravity corer (GGC) within the protected waters of San Francisco Bay. This provided an opportunity for the scientific party to become familiar with the operation of the coring equipment prior to its deployment/recovery in the open ocean. Between 5/28 and 5/29 we occupied four stations along a shelf-slope transect extending NW from the mouth of the Eel River (40 50' N, 124 19' W). Nominal depths for these stations were 70m, 150 m, 300 & 1000 m. We collected 5 MCs, 2 box cores (BCs) and 3 GGC. Due to heavy seas the MC deployments at the two deepest stations recovered sub-optimal cores (with disturbed sediment water interfaces), but in the interest of time we elected to move on to the next transect. The second transect (occupied between 5/31 and 6/2) began in the Cascadia Basin (46 45' N, 128 00' W) and extended eastward across the slope and onto the shelf in proximity to the mouth of the Columbia River (46 20' N, 124 18' W). 7 stations were occupied (2 in the Cascadia Basin and 5 on the Washington Margin at nominal depths of 2700 m, 2000 m, 1000 m, 600 m, 150 m, 90 m and 70 m) and we were successful in obtaining a total of 8 MCs, 3 GGCs and 5 BCs from these stations. In addition to the sediment sampling, we have collected surface and bottom water (for isotopic analysis of dissolved inorganic carbon) from the deep stations (> 500 m). The latter was obtained using a 10 L Niskin bottle attached to the MC. We also obtained larger quantities of deep water from the deepest Cascadia Basin sample using two 30 l Niskin bottles deployed using the hydrowire. Lastly, we have been collecting particulate matter from surface seawater (using the ship's clean seawater intake) at all stations by filtration onto glass fiber filters. To date, we have been successful in meeting almost all of our sampling objectives. We are approximately on schedule to complete the sampling program outlined for the second week of the cruise.
