Unformatted text preview: ©PROJECT OCEANOGRAPHY SPRING 2000 82 ACOUSTICAL OCEANOGRAPHY Unit 2. Lesson 4. Equipment and Sounds People use to Explore the Oceans Lesson Objectives: Students will gain knowledge and appreciation for research vessels and equipment found on them. Vocabulary words: satellite, Argos, tether, autonomous, buoy, iodiophone Vessels and Vehicles Vessels The ocean provides oceanographers will a difficult environment to study. Deep water, high pressure, and low light all hinder ocean exploration. In many cases is it necessary to reach locations far from land, conduct experiments over a long period of time, and bring samples and specimens back to the onshore laboratories. How would one go about studying this vast realm? Universities and research institutions have solved the problem of getting to the area in the ocean they want to study by having ships devoted solely to research processes. Research vessels roam all waters of the earth. The ships are equipped to provide housing for the researchers, electronic capability to support almost any kind of equipment, and satellite equipment to transmit data back to land. Ships are equipped with winches, cranes, A-frames, small boats, and other gear to do over-the-side work. They also have laboratory space for sample analyses and data processing. Most ships stay out for prolonged periods of time; several days to several months, while there are others that are only capable of handling a one-day cruise. Some ships provide a ‘base’ from which scientists can work. The ship serves as a center to deploy instruments. Some of these ©P ROJECT OCEANOGRAPHY SPRING 2000 83 ACOUSTICAL OCEANOGRAPHY include manned, and unmanned submersibles, remotely operated vehicles, buoys, CTD ’s and other sampole collection devices, like bottles and nets. At any given time, it might be possible to find vessels in the Pacific Ocean, the Polar Regions, Lake Baikal, and the Mediterranean Sea, as well as along coastlines. S ATELLITES The world’s oceans contain almost 3,000 drifters, buoys, and other objects collecting oceanographic data. These items are monitored by the only satellite system dedicated to monitoring and protecting the environment. This system is called Argos . The satellite flies at a low altitude, which means it can receive transmissions from low-power transmitters....
