Correlation between Indian Ocean summer monsoon and North Atlantic climate during the Holocene
Radiocarbon Marine Reservoir Effect in Human Remains from the Kitakogane Site, Hokkaido, Japan
Radiocarbon and Stable Isotope Analyses on the Earliest Jomon Skeletons from the Tochibara Rockshelter, Nagano, Japan
This study presents the results of carbon and nitrogen isotopic analyses of six human skeletons excavated from the Tochibara rockshelter (Nagano, Japan). The human skeletons were reported to be accompanied by “Oshigata-mon” type pottery dating to the Earliest Jomon period (8900 BP ≃ 6600 BP). A radiocarbon determination from charcoal associated with the human remains was reported to be 8650 ± 180 BP (GaK-1056). However, the depositional context o…
Compound-Specific Radiocarbon Ages of Fatty Acids in Marine Sediments from the Western North Pacific
Compound-specific radiocarbon analysis of five fatty-acid biomarkers was conducted for marine sediments collected from the western North Pacific. The fatty acids (C 12 to C 34 ) showed a typical bimodal distribution pattern with two maxima at C 16 and C 26 . Their carbon isotopic compositions ranged from −25.1‰ (C 16 ) to −31.8‰ (C 28 ), suggesting that they derived from terrestrial higher plants and marine organisms. A large variations of 14 C a…
Marine Radiocarbon Reservoir Effect in the Western North Pacific Observed in Archaeological Fauna
Faunal remains originating from terrestrial and marine mammals, and belonging to the same archaeological deposits were compared to evaluate the marine radiocarbon reservoir ages around the Hokkaido island, Japan. From five shell middens of different ages from the Jomon period (4900 BP) to the Ainu cultural period (800 BP), 107 animal bone samples were selected for radiocarbon measurements. The apparent age differences between Japanese deer and no…
