A075 GEOLOGISTS AND GEODESISTS
Include workers in the following occupations:
Geologists—-Study the composition, structure, and history of the earth's crust. Examine rocks, minerals, and fossil remains to identify and determine sequence of processes affecting development of the earth. Apply knowledge of chemistry, physics, biology, and mathematics to explain these phenomena and to help locate mineral and petroleum deposits and underground water resources. Prepare geologic reports and maps, interpret data and recommend further study or action. May be designated according to specialty as: Petroleum Geologist, Mineralogist, Petrologist, Photogeologist, Geophysical Prospector Oceanographer, etc.

Geophysicists—-Study physical aspects of earth, including its atmosphere and hydrosphere. Investigate and measure seismic, gravitational, electrical, thermal, and magnetic forces affecting earth, utilizing principles of physics, mathematics, and chemistry.

Geodesists—-Study size, shape and gravitational field of earth. Employ surveying and geodetic instruments such as transits, theodolites and other engineering instruments in setting up and improving network of triangulation over the earth's surface to provide fixed points for use in making maps.

Hydrologists—-Study distribution, deposition, and development of waters of land areas, including form and intensity of precipitation, and modes of return to ocean and atmosphere. Map and chart water flow and deposition of sediment. Measure changes in water volume due to evaporation and melting of snow. Study storm occurrences and evaluate data obtained in reference to such problems as flood and drought, forecasting, soil and water conservation, and planning water supply, flood control, irrigation, and crop production.
