fertilization results: A recent field test in the equatorial
Pacific of the iron fertilization hypothesis is reported in the
Sep. 8 issue of Nature. (See Prof. Pubs./Gen.
Interest/Science.) Fertilization did stimulate phytoplankton
growth, but measurements suggest that deliberate fertilization
would not alter atmospheric CO2 levels significantly. Andrew
Watson of the Plymouth Marine Laboratory, cited in a news report
in New Scientist (p. 17, Sep. 17), comments that
fertilization of the Southern Ocean might have a greater impact
on atmospheric CO2 levels, but that it would be far simpler to
burn less fossil fuel.
Sun-climate relationships: Statistical relationships
between solar activity and weather or climate on Earth have been
reported for years, but a physical mechanism linking them has
been absent. Two independent new studies that offer possibilities
are discussed in New Scientist (p. 14, Sep. 17). One of
them is also described in a recent paper by J.D. Haigh (see Prof.
Carbon model available: Software for Version 1.0 of the
Global Carbon Cycling Model (GLOCO), developed to simulate
processes that govern the global carbon cycle and to analyze the
effects of possible strategies for regulating greenhouse gas
concentrations, is now available from the Electric Power Research
Institute. (See related paper in Prof. Pubs./Gen. Interest/Clim.
Change Sci.) Contact Robert Goldstein, EPRI, POB 10412, Palo Alto
CA 94303 (415-855-2593).
Biosphere 2: After a controversial initial phase of
operation, the enclosed ecological test facility in the Arizona
desert is starting a new life on a solid scientific footing.
Texas billionaire sponsor Ed Bass announced that Biosphere has
entered a non-profit research agreement with the Lamont-Doherty
Earth Observatory, Palisades, N.Y., under the guidance of a board
of prominent academic scientists. (See Science, p. 1027,
Aug. 19; Nature, p. 495, Aug. 18.)
Global change data survey: The U.S. Interagency Working
Group on Data Management for Global Change (IWGDMGC) has begun to
determine priorities for improving existing data sets needed to
understand policy-relevant global change processes. It is
currently soliciting opinions on needed improvements to existing
data sets related to trace-gas dynamics; for instance,
documentation, quality assurance, or improved access. Contact
