As the JOIDES Resolution criss-crossed the sea early this year from the coast of Sardinia southeast to the toe of Italy, scientists were looking at the evolution of the basin from two perspectives: They were investigating the history of the young passive margin, or continental edge, on the northwest side of the basin; and they were reconstructing the way the basin has opened at sites in the southeast over several million years.
