Underwater Earthquakes
Seismologists investigating
undersea earthquakes have
found that molten rock
lubricates faults. This
decreases the amount of
friction between sides of
the fault and decreases the
intensity of earthquakes.

Rip Current Secrets Revealed
Rip currents flow in very
erratic patterns, not in
steady courses as previously
believed -- which may help
explain why they can be so
dangerous even for
experienced swimmers.

Uncovering the Mysteries of the Seas
For centuries, sailors in
the Indian Ocean have told
stories of seas glowing with
a dim, white light at night.
Satellite images have now
confirmed the appearance of
what seem to be

Sounds From the Sea
Manmade and natural sounds,
from boat engines to
rainfall, sound different
below the sea surface. To
study their impact of noise
on marine life, scientists
are submerging devices
called Passive Aquatic

Geophysicists Show That Crust Temperature Variation Explains Half Of Elevation Differences In North America
Geophysicists determined that tectonic mountain-building processes are not the only factor that determines elevation in North America. The temperature of the crust affects its density, and lower ... > more -
Engineering Students Build Next-Generation Bathyscaphe
Computer, electrical, and mechanical engineering students at the University of Florida have built a fully automated underwater vehicle. Driven by five thrusters and controlled by complex electronics, ... > more -
Atmospheric Scientists' Model Predicts Hurricane Threat Months In Advance
Meteorologists can make long range predictions about hurricane activity months in advance using what they call the Atlantic Meridional Mode. It is the relationship between sea surface temperature, ... > more -
Atmospheric Scientists Monitor Global Carbon
With the annual, steady increase of global warming and carbon discharge, atmospheric chemists are gathering air samples on behalf of the National Oceanic Atmospheric Administration (NOAA). Air ... > more -
Cool Pacific Waters May Not Affect Upcoming Hurricane Season
Like their more dramatic cousins El Niños, La Niñas -- the periodic cooling of ocean waters -- can have a dramatic impact on hurricanes, meteorologists say. The current La Niña, ... > more -
Geophysicists Blame La Nina Weather For Lost Time
Geophysicists have identified the very real physical mechanism that can lengthen or shorten the amount of time the earth takes to complete one rotation. During La Nina the temperature of the Pacific ... > more -
Seismologists Use Ultrasounds to Assess Quakes Faster
Using ultrasound imaging, seismologists can now determine the epicenter and magnitude of an earthquake quake within 10 to 20 minutes, precisely imaging which fault ruptured and where the rupture ... > more -
Soil Scientists Restore Marshes To Protect Coastal Ecology
Soil scientists spread material dredged from shipping channels over shore areas to help rebuild marsh areas. Wetlands along the shore protect the land from storm surges, create habitat for wildlife, ... > more -
Atmospheric Scientists Link Lightning to Ice Particles In Clouds
Satellite imaging is now helping atmospheric scientists link the amount of charged ice in clouds to lightning activity. Ice particles in thunderstorms can help increase precipitation, the scientists ... > more -
Atmospheric Scientists And Engineers Demonstrate Amount Of Pollution In U.S. Originating Overseas
Environmental scientists and engineers developed mathematical models to calculate the impact of pollution from Europe and Asia on areas in the United States. They found that almost twelve percent of ... > more
