Down to Earth
Science news about Earth and its planetary relatives
Our Down to Earth correspondent, Rachel Berkowitz, provides news
and updates on the latest research from the Earth sciences community. Besides
writing about Earth science for Physics
Today, Berkowitz also develops volcanic eruption models at Cambridge
University, where she's working on her PhD. Rachel grew up in Richland,
Washington; received her BA in physics at Yale University; and likes to climb
mountains and play violin.

A seismic story told by turbidites
Sediment deposits off the coast of Washington and Oregon reveal periodic tsunami and earthquakes of similar magnitude to the ones that struck Japan's Tohoku region in March 2011.
Two recent events (geologically speaking)
Two past events—one recorded in the Old Testament, the other in the diary of an 18th-century missionary—have left evidence of geophysical processes that are relevant today.
Geophysics yesterday and today
DOWN TO EARTH: To celebrate the 2011 December AGU meeting, Rachel Berkowitz takes a look at the first paper published in Journal of Geophysical Research.
It's becoming a smaller world, after all
DOWN TO EARTH: Climate change may cause both animal and plant species to shrink in size, which in turn could impact soil productivity.
Keepers of the wind in the Pacific Northwest
By taking advantage of some unusual geological formations, scientists in Washington and Oregon are finding ways to make wind energy viable.
A sustainable house in Tlemcen, Algeria
A team from Abou-Bekr Belkaid University in Algeria has designed an environmentally friendly house that is cheap to build, cool, and heat.
Why go offshore?
A conference this summer examined the financial, technical, and political issues that must be addressed before offshore wind farms can become a viable source of renewable energy.
Wind energy: why go offshore?
A conference this summer examined the financial, technical, and political issues that must be addressed before offshore wind farms can become a viable source of renewable energy.
Discontinuity under the Aloha State
An advanced seismic imaging technique has provided a more detailed picture of mantle structure beneath the Hawaii islands, but it hasn't resolved how the islands formed.
Io's magma ocean provides a view into Earth's past
Magnetic field data collected by NASA's Galileo contains evidence of the magma sea.
EGU 2011: Effects of aerosols on the East Asia summer monsoon
When it rains, it pours. But where and how much it pours over China, North and South Korea, and Japan during the East Asian summer monsoon (EASM) is changing.
EGU 2011: The slippery slope of alpine glaciers, permafrost, and newly formed lakes
At the general assembly of the European Geosciences Union, several experts spoke about climate change in alpine regions.
EGU 2011: Geodetic and inundation models of the Tohoku earthquake and tsunami
At the European Geosciences Union meeting in Vienna, Don Dingwell, the EGU president, introduced the session on the March 2011 Tohoku earthquake as the geoscientific community's way of paying respect and expressing condolences to the victims of March's seismic events.
EGU 2011: An outdoor volcano laboratory; lots of questions, and a few answers
Surface activity at Mount Stromboli has been recorded in detail for a thousand years. The resulting wealth of data provided ample material for a discussion at the general assembly of the European Geosciences Union in Vienna.
