Scenario-building for the Deepwater Horizon oil spill
Gary Machlis, Marcia K. McNutt
2010, Science (329) 1018-1019
In May 2010, the U.S. Department of the Interior (DOI) established a Strategic Sciences Working Group (SSWG) to assess how the Deepwater Horizon (DH) oil spill may impact the ecology, economy, and people of the Gulf of Mexico (GOM). It included scientists from diverse disciplines and federal, academic, and nongovernmental...
The thermal signature of volcanic eruptions on Io and Earth,
Ashley G. Davies, Laszlo P. Keszthelyi, Andrew J. L. Harris
2010, Journal of Volcanology and Geothermal Research (194) 75-99
We investigate a spectrum-based technique to identify the style of active volcanic eruptions on Jupiter's moon Io. Thermal remote sensing of Io has had to rely primarily on low-spatial-resolution data, similar to low-spatial-resolution satellite data applied to detecting and charting the temporal evolution of terrestrial hot spots. These terrestrial analyses use data from...
Seismic characterization of the fall 2007 eruptive sequence at Bezymianny Volcano, Russia
Weston A. Thelen, Michael West, Sergey Senyukov
2010, Journal of Volcanology and Geothermal Research (194) 201-213
We examine an eruptive sequence in late 2007 at Bezymianny Volcano to characterize the magmatic plumbing system and eruption-related seismicity. Earthquake locations reveal seismicity below and offset to the north of the volcano along a tectonic fault. Based on historical seismicity, the magma chamber is postulated to have a top...
Global climate changes recorded in coastal wetland sediments: Empirical observations linked to theoretical predictions
Alexander S. Kolker, Matthew L. Kirwan, Steven L. Goodbred, J. Kirk Cochran
2010, Geophysical Research Letters (37)
Whether coastal areas are experiencing, and responding to, an accelerated rate of global sea-level rise (GSLR) is critically important for the ∼2 billion people living near Earth's oceans. Accretion rates from a suite of physiographically diverse coastal wetlands surrounding Long Island, NY accelerated during the 20th century at 2.3 ±...

Systematic characterization and calibration of the Landsat sensors and the assessment of image data quality are performed using the Image Assessment System (IAS). The IAS was first introduced as an element of the Landsat 7 (L7) Enhanced Thematic Mapper Plus (ETM+) ground segment and recently extended to Landsat 4 (L4)...
Use of EO-1 Hyperion data to calculate spectral band adjustment factors (SBAF) between the L7 ETM+ and Terra MODIS sensors
Gyanesh Chander, N. Mishra, Dennis L. Helder, David Aaron, T. Choi, A. Angal, X. Xiong
2010, Conference Paper, IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2010 : 25 - 30 July 2010, Honolulu, Hawaii, USA
Different applications and technology developments in Earth observations necessarily require different spectral coverage. Thus, even for the spectral bands designed to look at the same region of the electromagnetic spectrum, the relative spectral responses (RSR) of different sensors may be different. In this study, spectral band adjustment factors (SBAF) are...

A. Angal, Gyanesh Chander, Taeyoung Choi, Aisheng Wu, Xiaoxiong Xiong
2010, Conference Paper, Geoscience and Remote Sensing Symposium (IGARSS), 2010 IEEE International
The Sonoran Desert is a large, flat, pseudo-invariant site near the United States-Mexico border. It is one of the largest and hottest deserts in North America, with an area of 311,000 square km. This site is particularly suitable for calibration purposes because of its high spatial and spectral uniformity and...

Environmental conditions affecting the efficiency and efficacy of piscicides for use in nonnative fish eradication
Peter James Brown
2010, Thesis
Conservation of native fish is a pressing issue for fisheries managers. Conservation efforts often require eliminating threats posed by nonnative fish by eradicating them with piscicides. The piscicides rotenone and antimycin are used for eradication but their application is often inefficient or ineffective. My goal was to increase the efficiency...

Knowledge of feral cat population dynamics is necessary to understand their ecological effects and to develop effective control strategies. However, there are few studies worldwide...
Predicting S-wave velocities for unconsolidated sediments at low effective pressure
Myung W. Lee
2010, Scientific Investigations Report 2010-5138
Accurate S-wave velocities for shallow sediments are important in performing a reliable elastic inversion for gas hydrate-bearing sediments and in evaluating velocity models for predicting S-wave velocities, but few S-wave velocities are measured at low effective pressure. Predicting S-wave velocities by using conventional methods based on the Biot-Gassmann theory appears...
