Join underwater explorer Jarrod Jablonski as he shares his incredible stories of cave diving and shipwreck expeditions. Jarrod Jablonski is the founder and CEO of Global Underwater Explorations (GUE) and holds several world records for cave diving excursions. GUE is the premier cave diving organization in the world and its members are on the cutting edge of diving technology. Jarrod will explain how these expeditions are evolving as new technology becomes available. The advances being made will revolutionize our thoughts about what it means to engage in "recreational" scuba diving. (1:35:22) Introduction to the National Cave Rescue Commission After it’s inception in 1979, the NSS’s National Cave Rescue Commission (NCRC) quickly developed into the foremost authority for cave rescue techniques and training. Every person involved with the NCRC is a volunteer, and NCRC courses attract a wide spectrum of students, including cavers and members of first responder units in cave-rich regions.
Th e NCRC conducts several courses, including an annual workshop that offers eight days of the best training, knowledge, and experience available for cave rescue techniques. Th e courses are always evolving and improving to keep up with new techniques and equipment. Th e NCRC was chartered by the NSS as a training and resource coordination body and as such has become the premier cave rescue training organization in the world.

Because of variations in geology, its caves show a remarkable difference from place to place. These differences can be explained through some observations -- some simple, and some quite complex. In this presentation, Dr. Art Palmer, a renowned hydrogeologist, lecturer, and author of Cave Geology, explains where this 'cavers' heaven' can be located.(2:03:51) Download a copy (144 MB) Introduction to The art and science of mapping caves, while similar to land surveying, is much more complex in that it is three-dimensional, and in addition to its boundaries, a cave's internal features need to be described. Cave mapping has evolved greatly over the past half century, from crude pace-and-compass drawings to exquisitely detailed computer-generated masterpieces. George Dasher, an environ- mental geologist for the State of West Virginia, is one of the best-known cartographers around; he literally wrote the book on how to map caves, On Station, published by the NSS. George has also run the NSS Cartographic Salon for two decades, and won two medal awards for his maps. Here George explains the basics of how to commit the essence of a cave to paper.

A variety of geophysical tools has been used to assist in this effort. Direct current electrical resistivity has proven to be useful in the identification and characterization of karst features, although the technique is far from perfect. Principles of electrical resistivity, application of the technique, comparison with other geophysical techniques, and examples are provided in the webinar.

West Virginia was one of two states where organized caving began in the United States, and which has more than 4500 documented caves at present.
This presentation will also promote the West Virginia Speleological Survey, the non-profit, volunteer organization that is attempting to document these caves. (59:49) Download a copy (74 MB) |
