Planktonic Foraminifera in the Continental Slope of the Northern South China Sea during the Last 130,000 Years and Their Paleo‐Oceanographic Implications
Abstract Core V36‐06‐3, approximately 12 m long, was raised from the lower part of the continental slope of the continental South China Sea from a water depth of 2,809 m. Analyses of planktonic foraminifera, CaCO 3 content and oxygen isotopes (δ 18 O) in shells of Globigerinoides sacculifer show tha...
