Land Subsidence in the United States [More info]
Describes and provides several detiled examples of impacts of human-induced land subsidence resulting from the extraction of subsurface water, including aquifer-system compaction, drainage of organic soils, dissolution and collapse of susceptible rocks.
Land use history of North America (LUHNA) [More info]
Report prepared with NASA on the importance of a historical context for understanding ongoing changes in land cover and land use in North America and the effect on the environment. Site contains primarily contents of a book edited by T.D. Sisk.
PDF Landscape consequences of natural gas extraction in Allegheny and Susquehanna Counties, Pennsylvania, 2004--2010 [More info]
Quantifies the landscape changes and consequences of natural gas extraction by digitizing indications of disturbance on NAIP aerial photographs and using these with the NLCD to show land use-land cover change.
PDF Landscape consequences of natural gas extraction in Bradford and Washington Counties, Pennsylvania, 2004-2010 [More info]
Quantifies the landscape changes and consequences of natural gas extraction by digitizing indications of disturbance on NAIP aerial photographs and using these with the NLCD to show land use-land cover change.
PDF Lead Poisoning in Wild Birds [More info]
Even though lead usage has declined due to environmental awareness and regulation, several human sources of lead continue to affect birds. Hunting ammunition and fishing gear are ingested by the birds, with toxic effects.
PDF Mapping, monitoring, and modeling Western Gateway Community landscape dynamics [More info]
Geospatial analysis of factors affecting communities that are adjacent to Federal lands, especially those lands subject to varying public interest and visitation.
Measuring human-induced land subsidence from space [More info]
Examples of the use of Satellite Interferometric Synthetic Aperture Radar to measure and map changes on the Earth's surface as an aid to understanding how ground-water pumping, hydrocarbon production, or other human activities cause land subsidence.
Measuring land subsidence from space [More info]
Describes the use of satellite-borne Interferometric Synthetic Aperture Radar (InSAR) to precisely measure, monitor, and assess small changes in land surface elevation resulting from human-induced or naturally occuring land subsidence.
More than broken jars and roof tiles: the environmental legacy of a Roman mineral industry at Plasenzuela, Extremadura, Spain [More info]
Adaptation of a poster presented at Metals in Antiquity Symposium, Harvard, September 10-13, 1997.
