December 14- December 21, 2001 vol. 38 no. 50 In Memoriam DEVONALD - Kim Devonald, Biological Oceanography graduate of SIO in 1983, died of cancer on November 18 at an early age. Kim was born on May 27, 1953, in Los Angeles and obtained her BS from Stanford. Her PhD advisors were Mike Mullin and Reuben Lasker. Kim's interests were at the interface of science and society. Her Ph.D. concerned the ecology of jack mackerel, a commercially-fished species. She went on to work at the EPA, first at the Office of Planning, Analysis and Accountability and subsequently at the National Center for Environmental Research (NCER). Peter Preuss, Director of NCER, wrote that "Kim was an employee who exemplified the highest standards of the EPA." Recollections of Kim include a tall, charming, athletic, Californian who loved avocados and swimming. Her height, smile, laugh, and positive demeanor were a good match for her advisor, Mike Mullin. She is survived by her sons David and Paul (12 and 13 years old) and her mother, Tessa. A memorial service was held December 3. Contributions can be made to The Hospice of North Virginia, 4715 N. 15th St., Arlington, VA 22205. (Dave Checkley) PETERSON - We are very sad to report that Ray Peterson passed away on Wednesday, December 6, from a protracted illness. He was 49 years old and very much in the prime of his professional and private life. Ray received his Ph.D. at Texas A&M University in 1987 under Worth Nowlin, measuring the transport of the Antarctic Circumpolar Current through Drake Passage. His post-doc work was done from 1988-1990 at the Institut fur Meereskunde in Kiel, Germany, under Gerold Siedler, measuring the circulation in the South Atlantic Basin off the Polarstern. Ray came to SIO in 1991 as an assistant research oceanographer and was promoted to associate research oceanographer in 1997. While as SIO he continued his studies of the circulation in the Southern Ocean, collaborating with Warren White on the Antarctic Circumpolar Wave; with Janet Sprintall on establishing high-resolution XBT sections across Drake Passage; with Terry Chereskin on the "fast fish"; and with Russ Davis on the Lagrangian drifter measurements of the Malvinas Current. He was equally at ease at sea deploying his instruments and at home analyzing the results. Oceanography was not only his vocation; it was also his avocation. To say that he was dedicated to physical oceanography would be a serious understatement. He was equally at home discussing science, history, and theology, all three subjects about which he was very passionate. While Ray was quiet and reserved, very serious almost to a fault, and the last to blow his own horn, he put his mark on just about everyone who worked with him. You just could not help yourself from becoming a better scientist and a more caring person for having known him. A memorial service was held last week. Cards or phone calls may be made to his wife of 11 months, Dorothy Nowroozian-Peterson, 1220 Navello Street, El Cajon, CA 92021, (619) 749-3339.

Ship News Melville Cook Expedition Leg 16 - Weekly Science Report,
Wednesday, December 12, 2001 - This was a week of surprises as we continued
our campaign of studying the origin of volcanic ridges and seamounts west
of the East Pacific Rise. We have been guided in our explorations by the
predicted bathymetry map of Smith and Sandwell, which is based on satellite
altimetry. But, the anomalous gravity lineations that are part of our
investigation have thrown us some curves. A seamount west of the Sojourn
Ridge turned out to almost twice as tall as expected, rising to within
200 m of the surface; the shallowest point in the study area. We scheduled
a dredge on another predicted seamount that turned out not to exist at
all! There is just a gravity anomaly, apparently caused by thin crust
and dynamic uplift of the lithosphere. Otherwise, the map has been a marvelous
guide. Dredging has been very successful, with interesting rocks returned
almost every time. All the rocks from the Sojourn Ridge have been relatively
old, but fresh basalt was found along the length of the tentatively named
Brown Ridge just to the north of the Sojourn. One dredge returned several
hundred pounds of twisted, tubular forms five to ten inches in diameter
and filled with plagioclase phenocrysts. Deployments of ocean bottom seismometers
in the northern part of the study area went smoothly, beginning an eleven
month period of recording earthquakes from around the world. The meals
prepared continue to be superb; although their quality is no longer a
surprise, it is still much appreciated. (PIs Don Forsyth, Spahr Webb,

The leg began in La Paz where US students disembarked and Mexican colleagues joined the cruise. Our work began in La Paz and Alfonso basins,two silled basins on the western margin of the Gulf of California with profiling using 3.5Khz to better characterize the geometry of the basins and to locate suitable coring locations. A CTD cast was conducted, which was followed by multicoring. Initial attempts to acquire gravity cores were unsuccessful as it had been on the first half of the cruise. Drs. Gorsline and Douglas suggested further modifications to the core catcher, which resulted in successful acquisition of gravity cores. Gravity coring proceeded with the acquisition of cores from Alfonso and La Paz basins. Water samples were collected from the hydrocast for CH4, O2, DIC and d18O (water). As with each of the previous sites we collected pore water samples from the multicores and gravity cores by Will Berelson and Masha Prokopenko. Sediment sections were collected from the multicore at mm scale and stained for later analysisby Bob Douglas, Lowell Stott, Kevin Cannariato and Francisca Staines-Urias.Biological samples were also collected from the sediment water interface by Dr. Joan Bernhard. Our second site was located on the eastern margin of the Gulf just east of Carmen basin. Successful hydrocasts, multicores and gravity cores were recovered. Samples were collected for each of the studies mentioned above. From E. Carmen we moved south along the margin to East Pescadero basin where another suite of cores was collected together with a hydrocast. While profiling with the 3.5kHz were encountered a north trending fault at approximately 650m water depth. We observed "distorted"reflectors closely associated with the fault. A short stop to conduct a hydro cast nearthe bottom near the fault revealed no elevated levels of methane in the bottom waters. From E. Pescadero we proceeded south to the Matzatlan margin where we successfully collected multicores and gravity cores at two depths, 420 and 550m. Two hydrocasts were conducted at this site, one off margin site in 2000 meters and another inboard site at 400meters. These hydrocasts were intended to collected water samples for CH4 analyses. Our final site was in San Blas Basin, a 450m deep tectonic basin just off the Islas Marias. A 3.5kHz profile was conducted along two NE trending lines acrossthe basin. An initial site was selected in 420m water. A multicore and gravity core was collected at this site. The ship was then repositioned approximately 5 miles to the southeast in 450 meters where additional gravity cores were attempted. However, we were unsuccessful in obtaining gravity cores at this site. Several problems were encountered with the seals on the gravity corer, resulting in "washed" cores. After a number of attempts,the seal was secured. However, we were unable to recover more than a couple of meters of mud. Each core washed upon retrieval to the ship. It appears that the mud was not stiff enough to be captured by the core catcher. After deploying our last core barrel the decision was made to abandon the site and make way after completing a hydrocast and plankton tow. This cruise was successful because of the tremendous efforts of each of the participants. The scientific party is especially indebted to the crew of the R/V New Horizon for making this a highly successful and enjoyable cruise. Special thanks are expressed to Ron Comer. Ron's helpfulness and friendly demeanor were much appreciated. CRUISE MAP INDEX/AREA/ CH SCI/INSTITUTION/ PORTS DAYS/AGENCY/ R/V Melville R/V New Horizon R/V Robert Gordon Sproul David Starr Jordan
