Controlling factors in stalagmite oxygen isotopic composition and the paleoprecipitation record for the last 1,100 years in Northeast Japan
ortheast Japan stalagmite d18O growth rate precipitation famine records
2017/4/10
Stable oxygen isotopic analysis was performed on the UT-A stalagmite with annual microbanding from the Uchimagido
Cave in Iwate Prefecture on the Pacific side of Northeast Japan. High-resolution anal...
Oxygen isotopes as a valuable tool for measuring annual growth in tropical trees that lack distinct annual rings
tropical tree with non-distinct annual rings cellulose oxygen isotopes fractionation model Styrax tonkinensis Ficus semicordata var. semicordata
2017/4/11
Some trees from tropical areas lack visually detectable and consistent annual growth rings. As such, we have measured
the radial variation of cellulose oxygen isotopes in trees that grow in seasonall...
Hydrogen and oxygen isotopic characteristics of precipitation in coastal areas of Japan determined by observations for 23 years at Akita and for 1–2 years at other several localities

sulfur isotope oxygen hydrogen pollution precipitation sulfate Korea East Asia
2017/4/11
To evaluate the source of sulfur and the extent of seasonal and local characteristics in Seoul’s precipitation chemistry,
we measured sulfur, oxygen, and hydrogen isotopic ratios of precipitation. Th...
