Core samples C8 and B2-9 from the seafloor of the Arctic were dated with 210Pb to obtain a consecutive sequence of oceanic sedimentary environments at the interval of a decade during 1880-1999 and 1889-1999. A variety of biomarkers were detected, including n-alkane, isoprenoid, fatty acid, sterol, etc.
This paper analyses and discusses the correlations between content of sulfate-reducing bacteria (SRB) and CaCO 3, Si, S, P, Cd, Fe, Ti, Pb, Hg in 34 sediments samples from the Chukchi sea and Bering sea, Arctic.
A statistical analysis is made for the percentage of trajectories which could travel from Gobi desert and Loess plateau to Arctic in total trajectories which originate from Gobi desert and Loess plateau in 1994 and 1995. From the statistical analysis, we get the concept that in winter and spring there are more trajectories from Gobi desert and Loess plateau to reach Arctic, about 10%, than in other seasons.
Studying the ozone distribution and variation is helpful for understanding the Arctic climate and environment and their impact on the global system, and for numerically forecasting climate and environment change.
Simple passive diffusive samples were used for the determination of SO 2, NO 2 and NH 3 in atmosphere from three stations at high latitudes and Arctic area. The concentrations of SO 2, NO 2 and NH 3 were found to be below 1.0, 0.3 and 2.0 μg/m 3 respectively.
This uplift not only led to profound climatic changes in the plateau, which resulted in the most extensive glaciation and the widest cold prairie grassland in the Quaternary, but also to a global climate change, that may have influenced the glacial cover in the Arctic Circle.
