From time-to-time members of the DEG run across web pages, slides and other resources that are helpful to the environmental geosciences community. There is a brief description accompanying each of these resources. If you believe you have such a resource, please send the details (title, link or file, with a brief description) to the DEG office

DEG prepared a slide show to tell others about this division's objectives and some of the content they produce and activities they provide. You are invited to download this PDF of these slides to share with your colleagues.

Hydraulic fracturing, a technique that has helped unlock vast new oil and natural gas supplies in the United States – and which has potential to do the same worldwide – has in this century become a contentious issue in which both proponents and opponents express strong views.

Proponents have said the use of hydraulic fracturing has resulted in historically high levels of recovered oil and gas, which has helped lower energy costs. Opposing arguments maintained hydraulic fracturing, most widely known by the colloquial term “fracking,” was dangerous to U.S. drinking water reservoirs.

Some resolution of the topic was achieved in June 2015, when the U.S. Environmental Protection Agency issued a long-awaited report on the practice, concluding that’s its four-year study found no signs of “widespread, systemic” pollution that were linked to “fracking.”

Still, for many people not in the industry, details about the technology, concepts, intent and utilization of the technique remain a mystery.

This paper, produced by the AAPG Division of Environmental Geosciences (DEG), has been offered to help answer those questions. Part of our mission is to communicate to the public the science behind issues that affect the exploration for and production of petroleum and other energy mineral resources.

The National Energy Technology Laboratory (NETL), part of the U.S. Department of Energy (DOE) national laboratory system, is owned and operated by the DOE. This is their carbon capture web page. Carbon capture involves the separation of CO2 from coal-based power plant flue gas or syngas. Commercially available first-generation CO2 capture technologies are currently being used in various industrial applications. However, in their current state of development, these technologies are not ready for implementation on coal-based power plants because they have not been demonstrated at appropriate scale, require approximately one-third of the plant’s steam and power to operate, and are cost prohibitive.

Have you done any fishing or recreational boating in Pennsylvania state parks? The Pennsylvania Geological Survey has released bathymetric (water-depth) maps for 20 state park lakes that should be of interest to all the anglers and boaters out there. The maps, part of the Survey’s open-file miscellaneous investigations, are the result of data gathering that began in January 2005.

The IPCC is a scientific body under the auspices of the United Nations (UN). It reviews and assesses the most recent scientific, technical and socio-economic information produced worldwide relevant to the understanding of climate change. It does not conduct any research nor does it monitor climate related data or parameters.
