Scientists use a rare mineral to correlate past climate events in Europe and Antarctica
Zunli Lu's research associate, Professor Rosalind Rickaby of Oxford University, digs out ikaite crystals from a sediment core obtained off the coast of Antarctica. The sediment cores and the crystals must be stored in a freezer or the crystals will melt
The new study is published in the April issue of "Earth and Planetary Science Letters"
Editor's Note: Media reports about this research have misrepresented the study's findings. For more information read a statement by Zunli Lu.
