Isotope Geochemistry
Paleoceanography is the study of the history and changes in the ocean's properties, chemistry, and biological activity over geological time. This field helps scientists understand past climate conditions, ocean circulation patterns, and how marine life adapted to changes in the environment. By examining various indicators, paleoceanography reveals insights into Earth's climate history, including how stable isotope ratios can indicate past temperatures and salinity levels, while also connecting with biogeochemical cycles such as the oxygen cycle.
