Cabinet members Anne Evans, Linda Robinson, and Charlie Robins have also made contributions. The challenge will remain open until December 31, 2001. If you would like to help SIO meet the Foundation's challenge, please contact the SIO Development office at (858) 822-1865.

HEY, SO WHO'S GOING TO DO.........EVERYTHING?!?!?! Ron-of-All-Trades McConnaughey will be retiring, too! We will have a big blow-out party for him on the Pier on Friday, April 6. Mark your calendars! (Jill Ives, x43948)

NEW OLD NEWS - We have just learned that some 3 years ago a new genus of flexibacteria (Lewinella) was named after an old Scripps microbiologist---Ralph Lewin! (L.I. Sly, M. Taghavit and M. Fegan. 1998. Phylogenetic heterogeneity within the genus Herpetosiphon: transfer of the marine species. Herpetosiphon cohaerens, Herpetosiphon nigricans and Herpetosiphon persicus to the genus Lewinella gen. nov. in the Flexibacter-Bacteroides-Cytophaga phylum. International Journal of Systematic Bacteriology, volume 48, pages 731-737.)

ASHES AT SEA - At 1404U 27 February 2001 we committed the ashes of our dear departed friend and shipmate Bob Stapleford to his final resting place in the Pacific Ocean, 17 miles west of Mission Bay, California, at position 32-44.78 N/117-35.49 W. Attending were the crew of R/V Robert Gordon Sproul and Bob's friends from the Dorman/Sauter research group. Psalm 23 "Grant Eternal Rest, O Lord" and The Lord's Prayer were recited after words of reflection on Bob's life were expressed. The ashes and a wreath were placed on the waters above an active OBS research array fulfilling Bob's wish to depart while "on station."

Progress report 2/26/01, R/V Melville cruise Cook 06 -We completed the HAWAII MR1 survey of the southern Mariana Trench region on. The data collected include complete bathymetric and imagery coverage of the backarc basin, arc, forearc and trench regions of the convergent margin system south of 13˜N. This includes high-resolution side-scan imagery of the Challenger Deep. We also collected gravity and magnetics data throughout the survey area. The HMR1 mapping system was recovered on Feb. 23 and the sampling portion of the cruise began with a series of dredges on bathymetric highs. Recovery included manganese encrusted reefal limestone from morphologically striking features, a series of thick platforms with discrete oval growths currently at depths of from 1500 to 3000 m and from 1 to 2 km diameters. A steep fault slope bounding the eastern side of the West Mariana ridge yielded a variety of volcanic and upper crustal material of diverse compositions. A spreading center feature in the western part of the backarc basin ridge crest yielded fresh lavas from two small volcanic sites. Wax cores from elsewhere along its length recovered fresh volcanic glass. Between the sampling sites the SeaBeam was used to fill in gaps in the HMR1 bathymetry coverage over shallow areas. The survey data was merged with an HMR1 data set collected in the eastern half of the backarc basin, arc and forearc areas to just oceanward of the Mariana Trench axis. The resultant data set shows the tectonic elements of region.These include a highly deformed forearc, the fragmentation of older volcanic arc centers just inboard of the forearc, the structure of a robust spreading ridge province in the eastern backarc basin, and a more normal spreading center in the westernmost portion of the backarc basin, an unusually deep graben in the narrow western tip of the basin and several horsts that likely separated from the West Mariana Ridge. This separation probably occurred recently because numerous earthquakes occur along its length. These faults have first motion solutions indicative of normal-faults.
