Sediment yields climate record for past half-million years

COLUMBUS, Ohio Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years. The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in ...

Time record of marine species formation in the Baltic Sea

In 2005 researchers at the University of Gothenburg and Stockholm University discovered a new species of seaweed. The species, which was named Fucus radicans , evolved from a bladder wrack (Fucus vesiculosus) ancestor from the Baltic Sea. Detailed studies of Fucus radicans show that, from an ev...
