Oceanographers study and map the ocean flow by using sensing devices aboard ships or underwater research crafts. Hydrologists examine the distribution, circulation, and physical properties of underground and surface water. They study the form and intensity of precipitation, its rate of infiltration into the soil and movement through the earth, and its return to the ocean and atmosphere. Scientific and technical abilities are essential to obtain knowledge of the field and to use the specialized equipment. Spatial skill is needed for comprehending maps, geologic structures, and the layout of sites.
Computer skills are necessary for constructing models and data processing.
Oral and written proficiency is needed in report writing and communicating findings. General memory, paying attention to detail, and working independently characterize many workers. Geoscientists have a need for discovery through their imagination, curiosity, and study. Mental stimulation is important to them, but they are often stimulated more by working with data than with people. They value the opportunity for variety.
