Volcano Pops to Attention by Ned Rozell - In the cold waters
of the Bering Sea sits a pyramid of volcanic rock that may someday
become another Aleutian island.
Jennifer Reynolds of UAF's
Global Undersea Research Unit, part of the School of Fisheries
and Ocean Sciences, recently announced the discovery of an undersea
volcano in the Aleutian Islands southeast of Semisopochnoi Island,
about 1,300 miles west of Anchorage.
As a volcano geologist, Reynolds
was intrigued when she heard that biologists exploring the coral
community clinging to an underwater pinnacle thought the peak
might be a volcano. When Reynolds and others investigated the
feature on a scientific cruise in summer 2003, they found a submerged
volcano with its summit about 2,000 feet above the surrounding
sea floor, which is about the same elevation Ester Dome rises
above Fairbanks.
Marine biologists Bob Stone
and Jon Heifetz of the National Marine Fisheries Service's Auke
Bay Observatory got a close look at the undersea volcano in 2002.
Stone was in a two-man submarine videotaping the rich coral and
sponge communities when he noticed the pinnacle had volcano-like
features. - Read

Global: OCEAN
SPONGING UP SOME WARMTH OVER NEXT 50 YEARS - NASA's improved
global climate computer model, which simulates and projects how
the Earth's climate may change, indicates that the oceans have
been absorbing heat since 1951 and will continue to absorb more
heat from the atmosphere over the next 50 years. This increasing
ocean heat storage suggests that global surface temperatures
may warm less than previous studies projected, while the ocean
acts as a bigger heat sponge. Further, such additional ocean
heating would likely change regional climate patterns.
Shan Sun and James Hansen,
both of NASA's Goddard Institute for Space Studies, New York,
NY, used NASA's Global Climate Model (GCM), one of the world's
leading computer climate models that simulate past and potential
future climate changes. The GCM has been enhanced with new "ocean
models" that better simulate how oceans currently absorb
heat and will respond to a warming global climate. The study
appears in the latest issue of the American Meteorological Society's
Journal of Climate. - Read
