Abstract

The sediment of Site 502 (W.Caribbean) is primarily foram-bearing nanno marl which accumulated at c.3 to 4 cm/thousand yr. The bottom of Site 502 (228.7 m) is about 8 m.y. old. The sediment of Site 503 (Equatorial Pacific) is primarily siliceous calcareous ooze which accumulated at about 2 to 3 cm/thousand yr. The bottom of Site 503 (235.0 m) is about 8 m.y. old. The sediment at both sites shows a distinct cyclicity of CaCO3 content. These relatively high accumulation rate, continuous, undisturbed HPC cores will enable a wide variety of high-resolution biostratigraphic, paleoclimatic, and paleoceanographic studies.- from Authors
