HEALY RESEARCHERS MAKE
A SERIES OF
STRIKING DISCOVERIES ABOUT ARCTIC OCEAN
Contrary to their expectations,
scientists on a research cruise to the Arctic Ocean have found evidence
that the Gakkel Ridge, the world's slowest spreading mid-ocean ridge,
may be very volcanically active. They also believe that conditions in
a field of undersea vents, known as "black smokers," could support previously
unknown species of marine life.
The findings were among a range of discoveries made by researchers aboard
the US Coast Guard Cutter Healy, an icebreaker equipped for science, and
a companion German research vessel, the Polarstern, in late August, early
in a nine-week cruise to the Gakkel Ridge, Earth's least volcanically
active mid-ocean ridge. (read the complete
