Without a vehicle, divers often becamesluggish, and their mental concentration was severely limited. Because undersea pressure affects their speechorgans, communication among divers has always been difficult or impossible. But today, mostoceanographers avoid the use of vulnerable human divers, preferring to reduce the risk to human life andmake direct observations by means of instruments that are lowered into the ocean, from samples taken fromthe water, or from photographs made by orbiting satellites. Direct observations of the ocean floor can be madenot only by divers but also by deep-diving submarines in the water and even by the technology ofsophisticated aerial photography from vantage points above the surface of more than seven miles and cruiseat depths of fifteen thousand feet. In addition, radio-equipped buoys can be operated by remote control inorder to transmit information back to land-based laboratories via satellite. Particularly important for oceanstudy are data about water temperature, currents, and weather. Satellite photographs can show the distributionof sea ice, oil slicks, and cloud formations over the ocean, Maps created from satellite pictures can representthe temperature and the color of the ocean's surface, enabling researchers to study the ocean currents fromlaboratories on dry land. Furthermore, computers help oceanographers to collect, organize, and analyze datafrom submarines and satellites. By creating a model of the ocean's movement and characteristics, scientistscan predict the patterns and possible effects of the ocean on the environment.Recently, many oceanographers have been relying more on satellites and computers than on research ships or even submarine vehicles because they can supply a greater range of information more quickly and more effectively. Some of humankind's most serious problems, especially those concerning energy and food, may be solved with the help of observations made possible by this new technology.
