"Another Round for Noisy Ocean
Temperature Test," Science, p. 1405, Mar. 5.
Oceanographer Walter Munk has funding for a second acoustic
temperature test, more limited in scope than the first, intended
to more accurately measure Pacific Ocean temperatures. Possible
harm to marine mammals from the acoustic sound waves used is
considered even less likely than during the first test, because
sound levels will be several orders of magnitude lower.
"Back to the Future," G.
Walker, Nature, p. 110, Mar. 11. Reviews the recent Royal
Society discussion on the climate of the Mesozoic era, and how
climate modelers and geologists hope to draw conclusions for
"Measuring Methane from Bovine
Burps," L. Dayton, New Scientist, p. 22, Mar. 6.
Explains the experimental approach being used by Australian
researchers to explore the factors that determine methane
emissions from ruminants.
"Euphotic Zone Study Moves
Forward," K. Denman, Eos, p. 134, Mar. 23. The IGBP
Scientific Committee recently gave the go-ahead to the Global
Ocean Euphotic Zone Study (GOEZS), a potential IGBP core program.
" Floods Flow from Small Climatic
Shifts," D. Pendick, Sci. News, p. 86, Feb. 6.
Geological evidence suggests that relatively modest shifts in
global average annual temperature and precipitation may have
dramatic regional effects on the frequency of catastrophic
"Stratospheric Project Studies
Climate," Eos, p. 98, Mar. 2. Although the World
Climate Research Program has emphasized the ocean-troposphere
system, it implemented the Stratospheric Processes and Their Role
in Climate (SPARC) project in March 1992. Research goals,
organization and activities are described.
"A Moss's Tale of Gassy Climate
Burps," Sci. News, p. 429, Dec. 19-26. Study of
ancient moss in Chile by James White of the University of
Colorado shows that 12,700 years ago, CO2 levels
climbed by 80 parts per million in just a few decades, possibly
as a result of abrupt changes in ocean circulation.
