Cold-grown plankton shells sharpen Arctic climate reconstructions

Cold-grown plankton shells sharpen Arctic climate reconstructions Sadie Harley Scientific Editor Robert Egan Associate Editor 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...
