Earth Science and the International Year of Caves and Karst

Friday, October 15, 2021

This webinar is part of the Earth Science Week 2021 webinar series.

Cave research represents the essence of Earth science since it involves going into and directly studying the Earth itself. Caves, and the karst areas in which most form, are highly valuable yet vulnerable features. They provide water to about 700 million people but are the most easily contaminated of groundwater supplies. Additionally, they can collapse to create sinkholes, swallowing roads and buildings, causing hundreds of millions of dollars in damages annually in the US alone. Join this presentation, which is part of the celebration of the International Year of Caves and Karst, to explore caves and karst around the world and the many aspects of the Earth sciences they include.

About the speaker

Dr. George Veni is the Executive Director of the National Cave and Karst Research Institute (NCKRI) and an internationally recognized hydrogeologist specializing in caves and karst terrains. Prior to NCKRI, he owned and served as principal investigator of George Veni and Associates, conducting multidisciplinary environmental karst management studies for more than 20 years. He has conducted karst research throughout the United States and in several other countries. He has chaired 16 international and multidisciplinary karst conferences, been a member of the governing board of the International Union of Speleology since 2002, serving as President since 2017 and organizing the International Year of Caves and Karst in 2021. He has served as a doctoral committee advisor for geological, geographical, and biological dissertations at the New Mexico Institute of Mining and Technology, The University of Texas at Austin, The University of Texas at San Antonio, and Aristotle University of Thessaloniki and Harokopio University in Greece, taught karst geoscience courses as an adjunct professor for Western Kentucky University for 12 years, and taught karst science and management workshops internationally for NCKRI since 2011. Three cave-dwelling species have been named in his honor. He has published and presented nearly 270 papers, including six books, on hydrogeology, biology, and environmental management in karst terrains.

Mapping Displacement and Subsidence with Time-series Radar

Wednesday, April 15, 2020

Background

Two related developments have moved the use of radar imagery into the operational realm. The supply of available data has increased greatly, especially with the freely-available Sentinel-1 satellites. And the analysis algorithms are now tested and established, producing reliable and standardized Information Products. One application in particular has benefited greatly from these synergistic developments; centimeter-scale measurement of surface motion on a regional scale. The ability to produce time-series displacement maps with a high point density has revolutionized the monitoring, and mitigation, of subsidence due to subsurface extraction of resources such as water or hydrocarbons.

Sinkhole Conference: Register Now - Deadline Very Soon!

Sinkhole Conference postcard
The Multidisciplinary Conference on Sinkholes and the Engineering and Environmental Impacts of Karst, generally known as “The Sinkhole Conference,” is the longest-running international conference of its type. Since 1984, engineers, geologists, hydrologists, land managers, biologists, and many others have gathered at these meetings to exchange cutting-edge information on karst and its many benefits and challenges. The Sinkhole Conference is managed by the National Cave and Karst Research Institute and this next conference is jointly organized with the Karst Waters Institute.

Abstracts due August 15th for "The Sinkhole Conference"

The Multidisciplinary Conference on Sinkholes and the Engineering and Environmental Impacts of Karst, generally called “The Sinkhole Conference,” is the longest-running international conference of its type. Since 1984, engineers, geologists, hydrologists, land managers, biologists, and many others have gathered at these meetings to exchange cutting-edge information on karst and its many benefits and challenges. Abstracts may be submitted until 15 August 2017, after which will be the time to submit your papers to accompany your abstracts. The papers of past Sinkhole Conferences have made those proceedings highly sought and widely cited. We expect the proceedings of the upcoming meeting will be the best yet.

Building the Modern World: Geoscience that Underlies our Economic Prosperity

Wednesday, August 2, 2017

Geoscience information is integral to the strength and growth of communities and provides the resources for economic growth. All building materials, energy resources, construction projects, and hazard mitigation efforts are fundamentally based on geoscientific data and the geoscience workforce.

Our speakers are:

Key topics to be addressed include:

  • The industrial materials and minerals used to construct buildings/infrastructure
  • The importance of readily available construction materials and the resulting demand for mines and quarries throughout the U.S.
  • How geoscience is used to determine whether or not sites are suitable for infrastructure development
  • How geoscience is used to help guide design and construction to enhance the quality of life, economic strength, and physical security of coastal areas

Webinar Co-sponsors:
American Association of Petroleum Geologists; American Geophysical Union; Consortium for Ocean Leadership; Geological Society of America; National Ground Water Association; National Science Foundation; Soil Science Society of America
