New study improves scientists’ ability to reconstruct how the climate and ocean circulation changed in the past

Researchers at iC3 have found a way to improve records of past high latitude ocean change using tiny plankton shells called foraminifera. By growing these foraminifera under controlled cold-water conditions, the team has extended a key temperature tool into the range most relevant for subpolar and polar oceans. The study’s results matter for anyone using marine sediments to reconstruct past climate, ocean circulation and carbon cycle change.
