*Landscape Disturbance Related to Natural Gas Extraction in the
Mid-Atlantic Region*

*Sponsored by ASPRS, CaGIS and GLIS*

*Date & Time:* May 23rd, 2014 12:00 PM – 1:00 PM EST

The American Society of Photogrammetry and Remote Sensing (ASPRS) GIS
Division in partnership with the Cartography and Geographic Information
Society (CaGIS) and the Geographic and Land Information Society (GLIS)
would like to invite our members to attend our third online seminar for the
2014 series.

*Landscape Disturbance Related to Natural Gas Extraction in the
Mid-Atlantic Region*

*Abstract:* Increased demands for cleaner burning energy, coupled with the
relatively recent technological advances in accessing unconventional
hydrocarbon-rich geologic formations, have led to an intense effort to find
and extract natural gas from various underground sources around the
country. One of these sources, the Marcellus Shale, located in the
Allegheny Plateau, is currently undergoing extensive drilling and
production. The technology used to extract gas in the Marcellus shale is
known as hydraulic fracturing and has garnered much attention because of
its use of large amounts of fresh water, its use of proprietary fluids for
the hydraulic-fracturing process, its potential to release contaminants
into the environment, and its potential effect on water resources.
Nonetheless, development of natural gas extraction wells in the Marcellus
Shale is only part of the overall natural gas story in the area of
Pennsylvania. Coalbed methane, which is sometimes extracted using the
similar technique, is commonly located in the same general area as the
Marcellus Shale and is frequently developed in clusters across the
landscape. The combined effects of these two natural gas extraction methods
create potentially serious patterns of disturbance on the landscape. This
presentation quantifies the landscape changes and consequences of natural
gas extraction for the natural gas play in Pennsylvania between 2004 and
2010. Patterns of landscape disturbance related to natural gas extraction
activities were collected and digitized using National Agriculture Imagery
Program (NAIP) imagery for 2004, 2005/2006, 2008, and 2010. The disturbance
patterns were then used to measure changes in land cover and land use using
the National Land Cover Database (NLCD) of 2001 as a baseline. A series of
landscape metrics are also used to quantify these changes and report on the
potential ecosystem effects.

*About the Speaker:  *Terry Slonecker is a research geographer in the
United States Geological Survey’s Eastern Geographic Science Center.  He
has over 30 years of experience in remote sensing and geospatial analysis
including positions with the U.S. Air Force, private industry and the U.S.
Environmental Protection Agency.  His current research interests include
hyperspectral analysis of heavy metals, hazardous substances, hydrocarbons,
and related vegetation stress.  He recently taught hyperspectral remote
sensing at the Afghanistan Geological Society in Kabul and has been
involved in several emergency response efforts including the Deepwater
Horizon spill in 2010. He received his master’s degree in Geographic and
Cartographic Sciences, and his doctorate in Environmental Science and
Public Policy from George Mason University, in Fairfax, Virginia. He is
currently working on mapping and measuring the landscape effects of natural
gas development and on evaluating remote sensing as a tool for hazardous
waste site monitoring.  On several occasions, he has served as an expert
witness for the U.S. Federal Government on remote sensing related matters.
