...discovery of Hawaii's untapped fluid assets was made by University of Michigan and U.S. Geological Survey scientists while they were charting temperature variations in the vicinity of Kilauea, the island's largest volcano crater. In an old B-25 bomber crammed with infra-red scanning equipment, they mapped the volcano's hot spots; then they enlarged their thermal survey by following two great rifts that led from the crater to the sea. Under the shore, and in nearby coastal waters, their infra-red detector revealed just the opposite of what they were searching for: large areas...
Cold Stills & Hot Springs. Geologist William Fischer, who headed the survey, soon recognized the significance of the findings: like an aerial divining rod, the infra-red scanner had spotted streams of cool, fresh rain water flowing out into the ocean. After completing the volcanic survey, the B-25 flew back and forth over Hawaii's entire coastline, eventually detecting a total of 219 shore areas that might have underground fresh-water springs. In one 5-sq.-mi. area in Hilo Bay, the scientists estimate, the discharge of fresh water amounts to 100 million gallons a day. Using the infra...
...Infra-Red Sky Lab. One of MRDC's proudest accomplishments thus far is an aerial reconnaissance laboratory, built aboard a Royal Thai Air Force C-47 transport. Equipped with cameras and infra-red sensors, similarly equipped planes have been making thermal maps showing the heat patterns of heavily forested areas in southern Thailand, which is presently plagued by Chinese-led bands of Communist terrorists. Once the normal heat pattern of an area has been established, trained operators of the secret equipment aboard the C-47 can quickly spot any thermal changes on the map - changes that could be caused...
Some of the infra-red techniques devised for the sky lab - as well as oth er MRDC developments - are also being used in Viet Nam, where there is no longer time or space for the methodical research going on in Bangkok...
...infra-red recordings also seem to rule out the theory that comets are composed primarily of ice and dust. Ikeya-Seki's high temperatures could have occurred only if it contained large amounts of metallic material. Most of the comet's lighter-weight chemical elements were probably boiled away during a previous close approach to the sun. The scientists also measured the total amount of energy Ikeya-Seki radiated before and after it swung around the sun; they calculated that it lost 65% of its mass and broke into two pieces...
