TOTALLY AWESOME! WE WON! - August 27 was the sold-out UCSD Cancer Center
Luau and Longboard Invitational fund raiser. Out of 20 highly-competitive
teams made up of super serious surfers from the local business and
political world, guess who came in FIRST PLACE? We did! The SIO Surf Team
WON! Special congrats go to Sam Iacobellis, Dave Sandwell, John Colosi,
Carsten Kooyman, and Jerry Kooyman. Each team is assigned a Surf Legend
and our team was proud to have Peter Townend, the 1976 world professional
champion. The too-cool first place trophy is on display in the Director's
Office, 104 Scripps Building. And, we hope to have the amazing perpetual
trophy on display at the Birch Aquarium soon! Way to go, guys!!!!!!!

SCRIPPS OPEN HOUSE - Tell a friend! All ocean enthusiasts and
architectural buffs are invited! The historical George H. Scripps Memorial
Marine Biological Laboratory ("Old Scripps") will be open for a free,
public Open House from 3-6 p.m., on Sunday, Sept. 10. The two-story
reinforced concrete building was erected in 1909-1910, and was the first
truly permanent structure of any of the shoreside marine biological
stations in the Western Hemisphere. The building is also an architectural
landmark, designed by and built under the supervision of famed San Diego
architect Irving J. Gill. For nearly a century "Old Scripps" has played a
significant part in the history of oceanography, so come by and get a tour
from knowledgeable docents! (Scripps Communications, x43624)

NSF AWARDS $2.3 MILLION GRANT - The National Science Foundation has awarded
a $2.3 million, three-year research grant to UCSD to create, demonstrate,
and evaluate a non-commercial prototype high-performance wide-area wireless
network for research and education. The project involves a
multi-institution collaboration led by Hans-Werner Braun of the San Diego
Supercomputer Center and co-principal investigator Frank Vernon of IGPP.
The project will create a wireless backbone network in Southern California
that will initially include backbone nodes on the UCSD campus and a number
of mountaintops in San Diego County, including Mt. Woodson, Mt. Laguna,
Mt. Palomar, and Toro Peak. Researchers in various disciplines and
educational communities will be able to gain Internet connection through
this backbone network. Two initial, quite different scientific applications
that the network will support are those of geophysicists at IGPP, whose
earthquake sensors are arrayed along the earthquake faults that cut through
the deserts and mountains of Southern California, and astronomers at SDSU's
observatory on Mt. Laguna. (SIO Communications, x43624)

Ship News

R/V New Horizon, Weekly Scientific Report - 27 August 2000: We're at sea
off Monterey Bay in week 2 of a multi-investigator experiment to study
regulation of coastal ecosystems by natural iron fertilizations that are
produced as upwelling events that inject sedimentary iron into the euphotic
zone. The weather is cooperating nicely with a series of small upwelling
events that drive iron concentrations up, followed by relaxations as the
wind dies. We're tracing the process with a number of novel tools,
including a towed, undulating vehicle with chemical sensors, two Autonomous
Underwater Vehicles operating from the R/V Point Sur and overflights from
Navy and NASA aircraft, including a remote salinity sensor. Profiling
glider groups from SIO and UW are operating their vehicles in the region,
as well. Support from Capt. Dave Murline, Res. Tech. Seth Mogk and the
officers and crew is excellent as we conduct a variety of operations,
including tows of undulating vehicles over the stern with simultaneous
surface sampling fish over the side. Major findings include the following:
underway mapping of algal species using DNA probes has revealed a major
bloom of Pseudonitzschia australis, a diatom that produces the toxin domoic
acid. The distribution of P. australis is anti-correlated with iron
concentrations - is the relationship driven by iron abundance or simply a
result of bloom formation? A series of ship-board iron enrichment
experiments have shown strong iron limitation in these coastal waters,
which parallels our field observations that the iron injected by upwelling
is very rapidly lost, while macronutrients remain in the euphotic zone.
Chemical sensor systems are working well: nearly 2000 shipboard iron
measurements have been made and an in situ nitrate sensor has been deployed
on CTD and undulating vehicle operations with great success. We have
conducted a series of intercomparisons with the autonomous vehicles, which
has reminded us of the fable of the turtle and the hare: an AUV operating
at 3 knots can easily beat a ship making 10 knots that has to frequently
stop for CTD stations at the close spacing required in the coastal zone.
