Historical trend of polycyclic aromatic hydrocarbons in a sediment core from Osaka Bay during the Meghalayan
Polycyclic aromatic hydrocarbons (PAHs) are produced by incomplete combustion of biomass and fossil fuel, yet PAHs have been rarely analyzed in coastal sediment cores as a tracer for human activities before industrialization. The aim of this study was to assess if the historical trend of PAHs can be related to past human activities. To this end, we have determined the concentrations of PAHs in a 9 m-long sediment core from Osaka Bay, which record…
Compound-Specific Radiocarbon Analysis of Organic Compounds from Mount Fuji Proximal Lake (Lake Kawaguchi) Sediment, Central Japan
Differential sources of sedimentary organic compounds in a volcanic region were revealed by determining radiocarbon content (Δ 14 C) of organic compounds in surface sediments from Lake Kawaguchi, at the northern foot of Mount Fuji, central Japan. The Δ 14 C values of C 16 fatty acid (−124‰) and chlorophyll a (Chl a ) (−133‰) were similar to the Δ 14 C of dissolved inorganic carbon (DIC) in surface water (−117‰), suggesting that a significant port…
A late Holocene molecular hydrogen isotope record of the East Asian Summer Monsoon in Southwest Japan
Precipitation in Japan is strongly affected by the East Asian monsoon system, resulting in wet summer conditions and relatively dry winter conditions. Few paleo-monsoon records exist from northeastern Asia, especially records showing decadal- to centennial-scale variability. Here we present a molecular hydrogen isotope (δD) record from Lake Kaiike, a small coastal lake in southwest Japan, to provide insight into monsoonal precipitation over the p…
Compound-Specific 14 C Dating of Iodp Expedition 318 Core U1357A Obtained Off the Wilkes Land Coast, Antarctica
This study applied compound-specific radiocarbon analysis (CSRA) to a 186-m-long sediment core (U1357A) taken from Adélie Basin located on the continental shelf off Wilkes Land, East Antarctica. The CSRA targeted C 16 fatty acid as well as C 16 ., fatty acid and cyclopheophorbide- a -enol isolated from the sediment. Due to their high degradation rate, these compounds are expected to occur in low abundances in relict organic matter deposited at th…
