Presented in table format are student enrollment data for geoscience disciplines at colleges and universities in the United States and Canada. Subfields for both countries include: geology; geophysics; oceanography; marine science; geological engineering; geophysical engineering; geochemistry; hydrology; mineralogy; paleontology; soil science; environmental science; and general earth science. Earth science teaching is also included for the United States. Data are presented for each of these disciplines alphabetically by institution (and alphabetically by state for the United States). Sections providing summary data and minority information are also included. Among the findings reported for the 1982-83 school year are those indicating that the total number of geoscience students at all academic levels in the United States (47,301) increased 6.4 percent over the previous academic year, that total male enrollment rose 6.7 percent and total female enrollment rose 5.5 percent over the 1981-82 figure, that women constituted 23.9 percent of all enrollments and earned 23.9 percent of all degrees, that minorities made up 2.6 percent of enrollees and earned 2.1 percent of all geoscience degrees in 1981-82, that enrollment increased at all three degree levels between 1981-82 and 1982-83, and that the 36,839 U.S. undergraduate majors represented a 7.43 percent increase over the previous year.
