Paleoproductivity records for the past 30 ka in the southern Nansha area, the South China Sea

This note presents productivity variations for the past 30 ka in the southe rn Nansha area, the South China Sea, from the gravity core 17962 (7 degrees 11 'N, 112 degrees 5'E, core length: 8 m, water depth: 1 968 m). Estimated surface productivity demonstrates that at the last glacial maximum the pro ductivity was about 1.6 times as much as that in the Holocene, and the chan ge may be ascribed to an increase of terrestrial nutrients as sea level low ered in the glacial time.
