Without avehicle, divers often became sluggish, and their mental concentration was severely limited.Because undersea pressure affects their speech organs, communication among divers has alwaysbeen difficult or impossible. But today, most oceanographers avoid the use of vulnerable humandivers, preferring to reduce the risk to human life and make direct observations by means ofinstruments that are lowered into the ocean, from samples take from the water, or from photographsmade by orbiting satellites. Direct observations of the ocean floor can be made not only by diversbut also by deep-diving submarines in the water and even by the technology of sophisticated aerialphotography from vantage points above the surface of more than seven miles and cruise at depthsof 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 importantfor ocean study are data about water temperature, currents, and weather. Satellite photographs canshow the distribution of sea ice, oil slicks, and cloud formations over the ocean. Maps created fromsatellite pictures can represent the temperature and the color of the ocean's surface, enablingresearchers to study the ocean currents from laboratories on dry land. Furthermore, computers helpoceanographers to collect, organize, and analyze data from submarines and satellites. By creating amodel of the ocean's movement and characteristics, scientists can predict the patterns and possibleeffects of the ocean on the environment.Recently, many oceanographers have been relying more on satellites and computers than onresearch ships or even submarine vehicles because they can supply a greater range of informationmore quickly and more effectively. Some of humankind's most serious problems, especially thoseconcerning energy and food, may be solved with the help of observations made possible by thisnew technology.
