William C. Stone (born December 7, 1952) is an American engineer, caver and explorer, known for exploring deep caves, sometimes with autonomous underwater vehicles. He has participated in over 40 international expeditions and is president and CEO of Stone Aerospace. Biography Stone was born on December 7, 1952, in Pennsylvania. He was an active caver in the Rensselaer Polytechnic Institute's Outing Club while studying for a B.S. in Civil Engineering, awarded in 1974. In 1976, while studying engineering at the University of Texas at Austin, Stone took part in an expedition to the Sistema Huautla in Oaxaca, Mexico, where his group set a new penetration depth record of . After obtaining a Ph.D. in engineering, Stone worked at the National Institute of Standards and Technology in Gaithersburg, Maryland from 1980 to 2004. While at the institute, Stone established the Construction Metrology and Automation Group. He led the group for seven years before stepping down to f ...

Peter Doran
Peter T. Doran is an American Earth scientist who is Professor of Geology and Geophysics and John Franks Endowed Chair at Louisiana State University. Prior to 2015, he was faculty in Earth and Environmental Sciences at the University of Illinois at Chicago. Doran specializes in polar regions, especially Antarctic climate and ecosystems. Doran was the lead author of a research paper about Antarctic temperatures that was published in the journal ''Nature'' in January 2002. Because he and his colleagues found that some parts of Antarctica had cooled between 1964 and 2000, his paper has been frequently cited by opponents of the global warming theory, such as Ann Coulter and Michael Crichton. In an opinion piece in the July 27, 2006 ''New York Times'', Doran characterized this as a "misinterpretation" and stated, "I have never thought such a thing ... I would like to remove my name from the list of scientists who dispute global warming." (The temporary phenomenon is related to the ...

ENDURANCE
Endurance (also related to sufferance, forbearance, resilience, constitution, fortitude, persistence, tenacity, steadfastness, perseverance, stamina, and hardiness) is the ability of an organism to exert itself and remain active for a long period of time, as well as its ability to resist, withstand, recover from and have immunity to trauma, wounds, or fatigue. The term is often used in the context of aerobic or anaerobic exercise. The definition of "long" varies according to the type of exertion – minutes for high intensity anaerobic exercise, hours or days for low intensity aerobic exercise. Training for endurance can reduce endurance strength unless an individual also undertakes resistance training to counteract this effect. When a person is able to accomplish or withstand more effort than previously, their endurance is increasing. To improve their endurance they may slowly increase the amount of repetitions or time spent; in some exercises, more repetitions t ...

Popular Science
Popular science (also called pop-science or popsci) is an interpretation of science intended for a general audience. While science journalism focuses on recent scientific developments, popular science is more broad ranging. It may be written by professional science journalists or by scientists themselves. It is presented in many forms, including books, film and television documentaries, magazine articles, and web pages. History Before the modern specialization and professionalization of science, there was often little distinction between "science" and "popular science", and works intended to share scientific knowledge with a general reader existed as far back as Greek and Roman antiquity. Without these popular works, much of the scientific knowledge of the era might have been lost. For example, none of the original works of the Greek astronomer Eudoxus (4th century BC) have survived, but his contributions were largely preserved due to the didactic poem '' Phenomena'' writte ...

Sinkholes
A sinkhole is a depression or hole in the ground caused by some form of collapse of the surface layer. The term is sometimes used to refer to doline, enclosed depressions that are also known as shakeholes, and to openings where surface water enters into underground passages known as ''ponor'', swallow hole or swallet. A ''cenote'' is a type of sinkhole that exposes groundwater underneath. ''Sink'', and ''stream sink'' are more general terms for sites that drain surface water, possibly by infiltration into sediment or crumbled rock. Most sinkholes are caused by Karst topography, karst processes – the chemical dissolution of carbonate rocks, collapse or suffosion processes. Sinkholes are usually circular and vary in size from tens to hundreds of Metre, meters both in diameter and depth, and vary in form from soil-lined bowls to bedrock-edged chasms. Sinkholes may form gradually or suddenly, and are found worldwide. Formation Natural processes Sinkholes may capture surf ...

DEPTHX
The Deep Phreatic Thermal Explorer (DEPTHX) is an autonomous underwater vehicle designed and built by Stone Aerospace, an aerospace engineering firm based in Austin, Texas. It was designed to autonomously explore and map underwater sinkholes in northern Mexico, as well as collect water and wall core samples. This could be achieved via an autonomous form of navigation known as A-Navigation. The DEPTHX vehicle was the first of three vehicles to be built by Stone Aerospace which were funded by NASA with the goal of developing technology that can explore the oceans of Jupiter's moon Europa to look for extraterrestrial life. DEPTHX was a collaborative project for which Stone Aerospace was the principal investigator. Co-investigators included Carnegie Mellon University, which was responsible for the navigation and guidance software, the Southwest Research Institute, which built the vehicle's science payload, and research scientists from the University of Texas at Austin, the Colorad ...
