Tiny Shells Indicate Big Changes to Global Carbon Cycle
Foraminifera shells are composed of calcium carbonate (CaCO3) and are found in many common geological environments. The ratio of O to O in the shell is used to indirectly determine the temperature of the surrounding water at the time the shell was formed. The ratio varies slightly depending on the … See more In geochemistry, paleoclimatology and paleoceanography δ O or delta-O-18 is a measure of the ratio of stable isotopes oxygen-18 ( O) and oxygen-16 ( O). It is commonly used as a measure of the temperature of See more Based on the simplifying assumption that the signal can be attributed to temperature change alone, with the effects of salinity and ice volume change ignored, Epstein et al. (1953) estimated that a δ O increase of 0.22‰ is equivalent to a cooling of 1 °C (or 1.8 °F).

Lisiecki and Raymo (2005) used measurements of δ O in benthic foraminifera from … See more WebForaminifera. : Life History and Ecology. Most of the estimated 4,000 living species of forams live in the world's oceans. Of these, 40 species are planktonic, that is they float in the water. The remaining species live on the bottom of the ocean, on shells, rock and seaweeds or in the sand and mud of the bottom. taiwan parcel tracking
