Marine Science is an interdisciplinary field, so it can be difficult to find one database or research tool that covers every subject area. The most interdisciplinary databases below are Web of Science and Scopus. However, many researchers will prefer to search in a Chemistry-specific database like MarinLit, SciFinder-n, or Reaxys. BIOSIS is an excellent subject database for all of the biology disciplines.
