Stirring the Oceanic Incubator
SCIENCE May 24 2002: 1406-1407
Robert P. Dziak and H. Paul Johnson

Abstract:
Earthquakes may affect hydrothermal systems hundreds of
miles away. But as Dziak and Johnson explain in their Perspective,
the effects differ widely between terrestrial and oceanic systems.
Recent studies have shown that changes in fluid temperature and
flow rate at seafloor hydrothermal vents may be delayed by several
days after the earthquake, whereas in terrestrial systems the change
is usually instantaneous. Biological communities are also affected
differently, depending on their reliance on geothermal versus
photosynthetic energy.
