Matt Hansen, Steve Stehman, Tom Loveland, Jim Vogelmann, Mark Cochrane
2009, The NASA LCLUC Program: an interdisciplinary approach to studying land-cover and land-use change 3-3
Quantifying rates of forest-cover change is important for improved carbon accounting and climate change modeling, management of forestry and agricultural resources, and biodiversity monitoring. A practical solution to examining trends in forest cover change at global scale is to employ remotely sensed data. Satellite-based monitoring of forest cover can be...
Pelagic habitat visualization: the need for a third (and fourth) dimension: HabitatSpace
C J Beegle-Krause J, Tiffany Vance, Debbie Reusser, David Stuebe, Eoin Howlett
2009, Conference Paper, Estuarine and coastal modeling : proceedings of the eleventh international conference, November 4-6, 2009, Seattle, Washington
Habitat in open water is not simply a 2-D to 2.5-D surface such as the ocean bottom or the air-water interface. Rather, pelagic habitat is a 3-D volume of water that can change over time, leading us to the term habitat space. Visualization and analysis in 2-D is well supported...
Earth science: lasting earthquake legacy
Thomas E. Parsons
2009, Nature (462) 41-42
Earthquakes occur within continental tectonic plates as well as at plate boundaries. Do clusters of such mid-plate events constitute zones of continuing hazard, or are they aftershocks of long-past earthquakes? Early on the morning of 16 December 1811, an earthquake of about magnitude 7 shook the centre of the United States...

Inversion of multichannel geophysical data with projected kernels
M. Andy Kass, Trevor P. Irons, Yaoguo Li
2009, Conference Paper, SEG technical program expanded abstracts 2009
Statistical de‐noising methods such as Principal Component Analysis modify data in a way not constrained by physics. In much the same way as frequency‐filtered data must incorporate altered frequency content into numerical interpretation, so must statistically rotated data include the rotation operator in inversion processes. We propose a method of...

Development of an objective‐oriented groundwater model for conjunctive‐use planning of surface water and groundwater
Yung-Chia Chiu, Ne-Zheng Sun, Tracy Nishikawa, William W.-G. Yeh
2009, Water Resources Research (45)
In this paper we construct an objective‐oriented model for conjunctive‐use planning of surface water and groundwater for the Warren groundwater basin in southern California. The goal of conjunctive‐use planning is to decrease high‐nitrate concentration while maintaining groundwater levels at desired elevations and meeting water demand. We formulate a management problem...

2009, Hydrobiologia (635) 263-277
Understanding spatial and temporal variation in the trophic base of stream food webs is critical for predicting population and community stability, and ecosystem function. We used stable isotope ratios (13C/12C, and 15N/14N) to characterize the trophic base of two streams in the Ozark Mountains of northwest Arkansas, U.S.A. We predicted...
