Late quaternary palaeoceanography of the Banda Sea, eastern Indonesian piston cores (Snellius-II Expedition, cruise G5)

Research output: Contribution to JournalArticleAcademicpeer-review

Abstract

Two Banda Sea piston cores were analysed for CaCO3 content, foraminiferal, radiolarian and spore-pollen distribution, and for oxygen and carbon isotopes. Late Quaternary palaeoclimatology and -oceanography are deduced. In this tropical area the two-step deglaciation is seen in the oxygen isotope profile. It did not lead to higher surface water temperatures but to a wetter climate as recorded in concurrent changes of the palynofacies. The core record further shows effects of an increasing monsoon regime on ocean circulation and land climate around 10 ka. At about 10.5 ka climate got wetter, while upwelling intensity increased around 9.2 ka and monsoonal intensity decreased again at about 2.7 ka.
