A high-resolution delta (super 18) O record from the northeastern Gulf of Mexico (Ocean Drilling Program Leg 100, hole 625B) provides a history of surface waters for the past 5.35 m.y. Negative delta (super 18) O anomalies between 0.3per mil and 3.0per mil in planktic foraminifera beginning at approximately 2.30 Ma can only have resulted from the discharge of isotopically light glacial meltwater from the Mississippi River. Meltwater anomalies implicate either the periodic presence of North American, mid-latitude, glacial ice since the late Pliocene or a drainage system very different from that of the present.
