Radiolarian record of the last 40 000 years in the Western equatorial Pacific

Polycystine radiolarians were studied in two box cores (ERDC 123Bx and ERDC 129Bx) from the Western equatorial Pacific Ocean (approx. 1°S, 161°E), sampled at 3cm intervals from top (ca. 0 to 4000-6000 YBP) to bottom (approx. 16 000 and 40 000 YBP, respectively). A total of 141 taxa were identified....
