Alaska: New
Well Near ANWR May Yield Important Data - At the request
of Governor Frank H. Murkowski, the Department of Natural Resources,
Division of Oil and Gas is soliciting interest in a stratigraphic
test well to be drilled on unleased state owned submerged lands
offshore of the eastern portion of the Arctic National Wildlife
Refuge (ANWR) coastal plain. A stratigraphic well is designed
only to provide geologic information about the area being tested.

subjected to extreme crushing pressures in the laboratory, as
in this experiment conducted by Freund and colleagues, its surface

Earthquakes:
Anticipating Earthquakes - High above Earth where seismic waves
never reach, satellites may be able to detect earthquakes - before
they strike. - For many people, earthquakes are synonymous
with unpredictability. They strike suddenly on otherwise normal
days, and despite all the achievements of seismology, scientists
still can't provide warning of an impending quake in the way
that weathermen warn of approaching storms.
Although earthquakes seem to
strike out of the blue, the furious energy that a quake releases
builds up for months and years beforehand in the form of stresses
within Earth's crust. At the moment, forecasters have no direct
way of seeing these stresses or detecting when they reach critically
high levels. - Click

Matanuska Glacier -
South-central Alaska
|
Glaciers: With
supercooling and the right geometry, 'warm' glaciers can trap
and transport silt - It may take them a century to advance
a few meters, but the bottoms of some glaciers churn with supercooled
activity, according to an article by a Lehigh University geologist
in the Aug. 14th issue of Nature magazine.
Edward B. Evenson, professor
of earth and environmental sciences, says his team's 12-year
study of the Matanuska Glacier in south-central Alaska sheds
light on a riddle that has long baffled geologists - how glaciers
are able to pick up and transport silt. - Click

Oceans: Ocean
Carbon Cycle Affected by Drought - Recent drought conditions
in the North Pacific Ocean near Hawaii have caused a decrease
in the strength of the carbon dioxide sink, according to a study
published this week in the journal Nature. - Click
