Discovery of an isotopically distinct Zealandia-Antarctic mantle domain in the Southern Ocean

February 6, 2019
Ken Sims geology professor

UW Department of Geology and Geophysics Professor Ken Sims and recent Ph.D. graduate Sean Scott are co-authors of an article, “An isotopically distinct Zealandia-Antarctic mantle domain in the Southern Ocean,” published by the scientific journal Nature Geoscience in January.

“The Australian-Antarctic Ridge is the remotest mid-ocean ridge in the world’s oceans and one of the last explored ridge segments, and, lo and behold, our isotope measurements of the samples we collected provided us with quite a surprise -- an entirely new domain in the Earth’s mantle,” Sims says.
