Refining Forams as Past Ocean Thermometer

Caption

The shells of plankton called foraminifera are a record of past ocean chemistry and therefore past climate. New work led by UC Davis and OSU scientists shows that mysterious bands of magnesium in the shells of foraminifera are caused by daily day/night cycles, helping to better define this model for measuring past climate.
