 Geochemical Ocean Sections Study

The Geochemical Ocean Sections Study (GEOSECS) is a significant scientific initiative aimed at understanding the chemical composition and properties of the ocean and how they relate to global biogeochemical cycles. Conducted from the mid-1970s to the early 1980s, GEOSECS focused on collecting and analyzing oceanographic data to investigate various aspects of the ocean's chemistry, including the distribution of nutrients, trace elements, and isotopes.
