Stable isotope record of Mediterraneas Sea sediments ...
Long eccentricity (400-kyr) cycles in carbon isotope records from the Pacific and Atlantic oceans and the Mediterranean sea of the past 5.0 Ma are compared. All records show maximum d13C values (d13Cmax) at eccentricity minima during the Pliocene, but this relationship obscured in the Pleistocene af...
