Habitat and fish population in the deep-sea Oculina coral ecosystem of the western Atlantic Habitat and fish population in the deep-sea Oculina coral ecosystem of the western Atlantic
In this paper, we describe results from mapping studies conducted in 2001 and improvements to reef fish populations that have occurred in the last few years. We find that less than 10% of the area contains intact Oculina coral thickets, which we continue to attribute primarily to trawling. In addition, we find increased grouper density and male abundance inside the protected area...

Evaluating MODIS data to estimate irrigated crop production in Afghanistan using a thermal-based ET fraction approach Evaluating MODIS data to estimate irrigated crop production in Afghanistan using a thermal-based ET fraction approach
Accurate crop performance monitoring and production estimation is critical for timely assessment of the food balance of several countries in the world. Recently, the Famine Early Warning System Network (FEWS NET) has been monitoring crop performance and to some extent relative production using satellite derived data and simulation models in Africa, Central America and Afghanistan where...

Analysis of multi-temporal geospatial data sets to assess the landscape effects of surface mining Analysis of multi-temporal geospatial data sets to assess the landscape effects of surface mining
Geospatial data sets, especially digital elevation data, have proven useful for characterizing and analyzing land surface conditions. Digital elevation models are routinely used for describing the morphology of the land surface in terms of slope gradient and aspect. Additionally, the elevation data are useful for deriving parameters that describe the local drainage conditions such as...

Landsat 7 scan line corrector-off gap-filled product development Landsat 7 scan line corrector-off gap-filled product development
The Landsat 7 Enhanced Thematic Mapper Plus (ETM+) scan line corrector (SLC) failed on May 31, 2003, causing the scanning pattern to exhibit wedge-shaped scan-to-scan gaps. The ETM+ has continued to acquire data with the SLC powered off, leading to images that are missing approximately 22 percent of the normal scene area. To improve the utility of the SLC-off data, the U.S. Geological...
