December 22, 2000 - January 5, 2001 vol. 37 no. 51 In Memoriam It is with great sadness that we announce that Michael Mahlon Mullin, Professor of Oceanography in the Marine Life Research Group at Scripps Institution of Oceanography, died suddenly on December 19, 2000, of complications following surgery. He was 63 years old. Mullin was active in both scholarship and administration, and his research featured studies of the dynamics of phytoplankton, zooplankton, and larval fish in the marine food web. In addition to his teaching and research, Mullin served in a number of administrative positions at Scripps: chairman of the Graduate Department, Associate Director, Director of the Marine Life Research Group, and Associate Dean for Academic Affairs. Mullin is survived by his wife of 36 years, the former Constance Hammond, whom he met while she was an undergraduate at Radcliffe College. He leaves three children, Stephen Joseph Mullin of Charleston, Illinois; and Keith Alan Mullin and Laura Mullin Thompson, both of La Jolla, and a grandchild, Alexandrea Christine Mullin. He is also survived by his mother, Alma Hill Mullin of El Paso, Texas, and a brother, Mark Hill Mullin of Oklahoma City, Oklahoma. A memorial service will be held at Scripps Institution of Oceanography on Saturday, January 6, 2001, at 2 p.m, adjacent to the Scripps Pier. In lieu of flowers, the family requests that donations be made in his memory to the Nature Conservancy. Calendar Thursday, January 4 ROUND TABLE DISCUSSION & SEMINAR & LUNCH - Jeffrey Tze-Fei Wong, Department of Biochemistry, Hong Kong University of Science & Technology, will present "Origin, Evolution and Mutation of the Genetic Code: Why We Might Be Alone or Close to Alone in the Universe" at the UCSD Faculty Club at 2 p.m. There will be a hosted lunch and round table discussion with Dr. Wong beginning at 12 noon.

1 - The Birch Aquarium and San Diego Harbor Excursion have teamed up in
a unique partnership to offer DAILY whale watching cruises with Scripps
naturalists out of San Diego Bay. The Birch Aquarium has long been recognized
as San Diego's center for gray whale migration information and we are
proud to now offer daily whale watching opportunities. Scripps naturalists
will be on board each cruise to help search for gray whales as they migrate
past our shores on their way to the lagoons of Baja California, Mexico,
to breed and give birth. Our naturalists will share gray whale artifacts
and specimens, and a free gray whale information sheet. Each whale watcher
will also receive a "whale-of-a-savings" coupon with tempting discounts
to Anthony's Fish Grotto, San Diego Maritime Museum, Seaport Village,
San Diego Harbor Excursion, and the Birch Aquarium. Cruises: Daily at
10:15 a.m. and 1:30 p.m. from December 26-April 1 TREE OF LIGHTS - Thanks also goes to Shawn Stewart and Gary Reese for also helping to get the Tree of Lights up and running on the Pier. In consideration of our power problems, the tree will be lighted each day from 4 - 7 p.m. only. (Jill Ives, x43948) DEADLINE FOR THE 2000 SIO CONTRIBUTIONS--2/1/2001--Each year the Technical
Publications Office requests reprints of your publications. The Contributions
publications are the only official record of papers published by Scripps
authors for each calendar year. Data from the bibliography may be broken
down into divisions, disciplines, used in major proposals, or in other
bibliographic material. The citations are kept on computer for the convenience
of all, and they are available on Scripps's web site as a searchable database.
The deadline for submitting reprints to the Editorial and Publications
Committee for the 2000 Contributions is Thursday February 1, 2001. Guidelines
for submission may be found on the Web at www.sio.ucsd.edu/scripps_news/techpubs/contribguide.html/.
For each reprint published during calendar 2000, please submit 3 copies
along with a reprint information form to the Technical Publications Office
(0233B). Reprint forms are available by calling x41295 or e-mail to techpubs@sio.ucsd.edu.
AWARDS, HONORS AND IN MEMORIAM - As the new editor of Explorations, I invite you all to forward information regarding those students, faculty, and staff who have received awards and honors, or who have passed away in fiscal 2000 (July 1, 1999 to June 30, 2000). Please send these to Marianne Maggini, mmaggini@ucsd.edu, x24486 by Jan. 19, 2001. FUNDS AVAILABLE - Funds for research and travel to scholarly meetings are available to Academic Senate members and Research Scientists. Please visit our website at http://www-senate.ucsd.edu/cor/ CALL_ SIO.HTML for our current call for applications. For further information contact Michelle Null, x42130. HOLIDAY SCHEDULE - The following departments will be closed for the holidays as noted: Academic Personnel December 21 - January 2 Ship News R/V Melville, Final Scientific Report, 12/20/00, Cook Leg 04: We have charted a paleo-triple junction across 3,200 km (2,000 miles) of South Pacific seafloor - the equivalent to the distance from the southern tip of Baja California to Seattle, Washington. In the mid-Cretaceous period, this feature joined three spreading ridges that separated the Pacific, Farallon and Phoenix plates. We have primarily used Seabeam 2000 to chart the intersection of two sets of lineated abyssal hills that mark the former trends and locations of two of the three spreading plate boundaries. This ridge-ridge-ridge triple junction trace extends north- northwest from the magnetic lineation bight outlined by anomaly 34 at 83 million years ago to its origin between Manihiki Plateau and Tongareva Atoll. Thus, we name this tectonic feature the Tongareva triple junction. The trends of the triple junction trace and the associated abyssal hills/fracturezones suggest that spreading was very fast on the Pacific-Farallon and Farallon-Phoenix ridges during the mid-Cretaceous period, sometimes exceeding 20 centimeters per year whole rate, which is faster than any rates today. Gravity profiles across the triple junction trace suggest that the oceanic crust is significantly thicker on the eastern, slower spreading side than on the western, faster spreading side and that an extremely thinned cleft in crustal thickness is often present at the triple junction itself. The Tongareva triple junction probably first formed about 115 million years ago somewhere between 5 and 9 degrees South as a ridge-fault-fault triple junction, with the Galapagos Fracture Zone and the eastern edge of Manihiki Plateau marking the two transform faults. Soon afterwards, an unknown amount of thickened oceanic plateau crust was rifted from the eastern side of Manihiki Plateau and the unstable ridge-fault-fault triple junction evolved to a more stable ridge-ridge-ridge structure for the majority of its mid-Cretaceous history. This cruise is being funded by a grant from the Regents of the University of California and the National Science Foundation.
