Narrator: This is Science Today. Understanding
day-to-day changes in the atmosphere has long been
a key factor in determining the global climate,
but it wasn't until fairly recently that scientists
came up with a technique to measure such changes
in the ocean. Peter Worcester, a research oceanographer
at the University of California's Scripps Institution
of Oceanography, has been working with acoustics
to track large-scale changes in the ocean in an
effort to draw maps similar to those of the atmosphere.
Worcester: We're really getting to the point
where, not this year but maybe in five years, we'll
be able to generate maps like that of the ocean.
Temperature structures, salinity structure, its
current structure. Up until now, oceanography's
been kind of backwards relative to the atmosphere
in that we haven't been able to measure the day-to-day
Narrator: Worcester says ocean measurements
are needed to determine the effects of global warming
on the climate.
Worcester: The ocean can store more heat
in its top few meters than the entire atmosphere.
To understand what's happening to our planet in
terms of it's climate, it's weather, you really
need to understand both of these.
