NOAA scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and map objects on the sea floor such as shipwrecks, and map the sea floor itself. There are two types of sonarâactive and passive.
Tools Used by Scientists. Scientists use complex and precise tools to perform research. In the field, scientists use highly accurate measuring devices to find data about how a system or process works. To record and analyze the data they find, scientists often use powerful software programs and computers. Depending on the type of research they do, scientists may use dozens of tools in the course of one research project. (michaeljung/iStock/Getty Images)
