Quaternary paleoceanography of the central Arctic based on Integrated Ocean Drilling Program Arctic Coring Expedition 302 foraminiferal assemblages
[1] The Integrated Ocean Drilling Program (IODP) Arctic Coring Expedition (ACEX) Hole 4C from the Lomonosov Ridge in the central Arctic Ocean recovered a continuous 18 m record of Quaternary foraminifera yielding evidence for seasonally ice-free interglacials during the Matuyama, progressive development of large glacials during the mid-Pleistocene transition (MPT) 1.2–0.9 Ma, and the onset of h...
متن کاملThe ‘‘African humid period’’ and the record of marine upwelling from excess Th in Ocean Drilling Program Hole 658C
[1] Using a high-resolution Th normalized record of sediment flux, we document the deglacial and Holocene history of North African aridity and coastal upwelling at Ocean Drilling Program Hole 658C. At both the end of the Younger Dryas and after the 8.2 ka event, there are significant drops in terrigenous accumulation at our site, indicating an increase in the monsoon moisture flux over Africa a...
متن کاملHigh-resolution record of the Matuyama-Brunhes transition constrains the age of Javanese Homo erectus in the Sangiran dome, Indonesia.
A detailed paleomagnetic study conducted in the Sangiran area, Java, has provided a reliable age constraint on hominid fossil-bearing formations. A reverse-to-normal polarity transition marks a 7-m thick section across the Upper Tuff in the Bapang Formation. The transition has three short reversal episodes and is overlain by a thick normal polarity magnetozone that was fission-track dated to th...
متن کاملOcean Drilling Program Leg 184 Preliminary Report South China Sea
The Asian monsoon system is a major component of both regional and global climate. Evolution of monsoonal climates in southern Asia is linked to the growth of the HimalayanTibetan orogen, the opening and closing of marginal seas, and changes in global climate. The location of the South China Sea (SCS) between East Asia and the “maritime continent” is ideal to record the paleoceanographic respon...
متن کاملMagnetic Intensity Variations in Sediment Cores from Leg 128 1
Variations of the intensity of magnetization in the sediment cores from Sites 798 and 799 were examined. Closely correlated variations in the magnetic intensity enabled estimation of the relative change of the sedimentation rate between the two sites. A high sedimentation rate of more than 30 cm/1,000 yr was inferred for about 550,000 yr ago at Site 799. The sedimentation rate was used to compa...
