In Memoriam

It is with a sad heart that we announce that Bill Nierenberg, director of
Scripps Institution of Oceanography and vice chancellor of marine sciences
from 1965-1986, passed away Sunday, September 11, 2000. His career has
been characterized by his intense drive, from a childhood of poverty to
widely acknowledged stature in science. Bill served SIO the longest of any
of its nine directors and he had a profound impact. I find myself quite at
a loss to give a full and broad review of his impact on science, national
policy, and Scripps right now so I will just say I truly benefited from his
friendship. We will ALL miss Bill. **A memorial service will be held at
the Martin Johnson House, on Thursday, September 28, at 3 PM.**

BYE, JOHN! After many years at SIO, our friend John Sunde has called it
quits! John is retiring on Friday! John has always been a very kind and
accommodating man who was always just a phone call away---we will surely
miss him. John started at UCSD as a Physical Plant operator for two years.
Then he was transferred down to SIO where he stayed for 18 years. We all
wish you a wonderful retirement, John! Come back and visit us often!

R/V Melville, Weekly Scientific Report, 9/7/00: Cook 01 (CHARYBDIS -
Chemical Analysis and Research on the Biological Dynamics of Iron in the
Sea (with the "Y" standing for "why?")). The first week of the cruise was
essentially spent in transit from San Diego to the Costa Rica Upwelling
Dome (~8 deg. North, 89 deg. West). The Costa Rica Upwelling Dome is an
excellent high nutrient low chlorophyll (HNLC) site for studies of iron
limitation. In this offshore divergent gyre, high macro nutrients
(nitrate, phosphate and silicic acid) are observed in the surface waters.
The pycnocline and nutricline dome such that 30 (M nitrate is found within
20 meters of the surface and fresh upwelled surface water in the region has
approximately 10 (M nitrate and silicic acid. We observed a massive bloom
of phycoerythrin-containing cyanobacteria that dominated the system. As
the bloom progressed, cells drew down the nitrate to roughly 2 (M, leaving
10 (M silicic acid, while cyanobacteria cell densities increased to 3
million per mL, values greater than we have ever seen in the oceans or even
in laboratory cultures. We carried out a number of grow-out experiments to
examine the response of the biological system to different metal additions.
We also carried out a major transect through the upwelling dome to
characterize the spatial distribution of macro and trace nutrients and
various diagnostic indicators of iron stress. Extremely elevated levels of
natural, organic iron chelators were observed within the bloom. By the end
of the second week, we were in the vicinity of the Galapagos Islands
carrying out a series of transects from the Equatorial HNLC regions to the
West and East of the Galapagos Islands towards the shelf areas of the
islands. Once again, macro nutrients and trace nutrients (iron, zinc,
cobalt, etc.) were analyzed along with a suite of other biological
parameters and diagnostic indicators of iron stress. This provided us a
chance to test the "island effect," whereby the iron weathered from the
Galapagos Islands and platform enriches the surrounding waters, thereby
reducing iron limitation and allowing for higher phytoplankton biomass. We
have now left the Galapagos Islands and are heading across a 700 mile
stretch of HNLC waters to the Peru Coastal Upwelling System. Our clean
surface pumping system deployed off the Melville is working great! It
allows us to continually monitor trace metal concentrations on roughly a
half-hour time scale and provides an unlimited supply of clean surface
seawater for all the various biological studies. Our shipboard analyses
(e.g., nutrients, dissolved Fe, flow cytometry and fluorescence properties)
are invaluable for designing the appropriate studies. Operations are
running smoothly (as are the sea conditions). The Captain (Eric Buck),
Marine Technicians (Bob Wilson, John Chatwood and Rob Palomares) and the
crew have all been exceptionally supportive and professional. (Ken

R/V New Horizon, Weekly Scientific Report, 09/10/00 - Conducting
hydrographic surveys of inshore waters between Point Reyes and Point Sur
for the Naval Oceanographic Office. Completed 2-25-hour time series at the
offshore edge of the northern and western traffic lanes in the Gulf of the
Farallones. The spatial CTD survey was based upon the CalCOFI grid between
Line 60 and Line 70. Stations were spaced 10 nm across shore and 20 nm
along shore, extending from the coast to station 70 offshore. Soundings
were made to 1000 m where water depth permitted. Four gravity cores were
collected on the SW flank of Sur Ridge. Time series exhibited semi-diurnal
variability. Fresh waters (S<33) were observed to a depth of 50 m in the
northwestern portion of the Gulf of the Farallones. Flow along the upper
slope in this region was equatorward. To the south of San Francisco, flow
along the upper slope was poleward. (Dr. Curt Collins, NPS)

R/V Roger Revelle, Weekly Scientific Report, 14 September 2000:The second
week of the HOME SeaSoar/Doppler sonar survey began with a southward leg
along the Hawaiian Ridge between French Frigate Shoals and the Kauai
Channel. Along the way, we deployed five microstructure profiling floats
(LAMP, Lagrangian Microstructure Profiler) for Jeff Sherman. The floats
profile from the surface to nearly 400 m, completing the cycle in two
hours. All five LAMPs are currently reporting via ARGOS. The LAMPs will
be recovered during the last week of the cruise. We are now in the midst
of a survey of the Kauai Channel. The survey consists of five across-ridge
legs extending 96 miles on either side of the ridge. It is now spring
tide, and we have observed large, presumably tidally generated, internal
waves predominantly on the southwest side of the ridge. The internal waves
are evident in both isopycnal displacement and velocity shear. The first
HOME ping-pong championship concluded today (9/13/00) with Rey Esteban
capturing the coveted first prize. (Dan Rudnick, UCSD/SIO)
