Landsat ETM+ False-Color Image Mosaics of Afghanistan Landsat ETM+ False-Color Image Mosaics of Afghanistan
In 2005, the U.S. Agency for International Development and the U.S. Trade and Development Agency contracted with the U.S. Geological Survey to perform assessments of the natural resources within Afghanistan. The assessments concentrate on the resources that are related to the economic development of that country. Therefore, assessments were initiated in oil and gas, coal, mineral...

Global spatial deconvolution of Lunar Prospector Th abundances Global spatial deconvolution of Lunar Prospector Th abundances
We have completed the first global spatial deconvolution analysis of planetary gamma‐ray data for lunar Th abundances as measured by the Lunar Prospector Gamma‐ray Spectrometer. We tested two different spatial deconvolution techniques – Jansson's method and the Pixon method – and determined that the Pixon method provides superior performance. The final deconvolved map results in a...

Protecting Your Family From Earthquakes-The Seven Steps to Earthquake Safety (in Spanish and English) Protecting Your Family From Earthquakes-The Seven Steps to Earthquake Safety (in Spanish and English)
This book is provided here to share an important message on emergency preparedness. Historically, we have suffered earthquakes here in the San Francisco Bay Area that have caused severe hardship for residents and incredible damage to our cities. It is likely we will experience a severe earthquake within the next 30 years. Many of us come from other countries where we have experienced...

Geological processes and orchid biogeography with applications to southeast central America Geological processes and orchid biogeography with applications to southeast central America
This contribution owes its origins to a paper presentation by Dr. Calloway H. Dodson at the Second International Conference on Neotropical Orchidology held in San José, Costa Rica in May of2003 (Dodson 2003). Dr. Dodson outlined some ofthe reasons to suspect that regional geological fac-tors may play important roles in orchid speciation and biogeography and gave examples from the...

Earthquake hazard in the heart of the homeland Earthquake hazard in the heart of the homeland
Evidence that earthquakes threaten the Mississippi, Ohio, and Wabash River valleys of the Central United States abounds. In fact, several of the largest historical earthquakes to strike the continental United States occurred in the winter of 1811-1812 along the New Madrid seismic zone, which stretches from just west of Memphis, Tenn., into southern Illinois. Several times in the past...

Community structure of foraminiferal communities within temporal biozones from the western Arctic Ocean Community structure of foraminiferal communities within temporal biozones from the western Arctic Ocean
Community structure is often an overlooked dimension of biodiversity. Knowledge of community structure, the statistical distribution of the relative species abundance vector, makes possible comparisons and contrasts across time, space, and/or environmental conditions. Our results indicate that species of Arctic foraminifera in age-correlated cores from abyssal depths are each best...

Magnetic character of a large continental transform: an aeromagnetic survey of the Dead Sea Fault Magnetic character of a large continental transform: an aeromagnetic survey of the Dead Sea Fault
New high-resolution airborne magnetic (HRAM) data along a 120-km-long section of the Dead Sea Transform in southern Jordan and Israel shed light on the shallow structure of the fault zone and on the kinematics of the plate boundary. Despite infrequent seismic activity and only intermittent surface exposure, the fault is delineated clearly on a map of the first vertical derivative of the...
