Other data, including analyses of the sediments surrounding the fossils, reveal that the climate got wetter and the ecosystem was presumably more productive as average temperatures climbed, nixing the notion that these animals shrank because of a reduced food supply.
This study presents comprehensive geotechnical data of the natural marine sediments cored from the hydrate occurrence regions during the Ulleung Basin Gas Hydrate Expedition 1 (UBGH1), East Sea, offshore Korea in 2007.
Our further work includes collecting geochemical data of marine sediments from the scientific literature to establish a database, analysis and use of appropriate interpolation methods to gain information for ocean regions with sparse sediment data available, as well as the estimation and comparison of carbon stocks of more maritime nations.
The analysis of palynological data from the sediment core of Lake Bolshie Toroki using quantitative methods has made it possible to reconstruct changes of the dominant types of vegetation and mean July air temperatures.
The detachment rate was calculated from the spatial distribution data of sediment concentrations measured with sediment-laden water samples simultaneously taken along the gullies at one meter intervals.
Radiocarbon and optically stimulated luminescence dating are applied to add numerical data to the relative ages of the sediments and landforms.
The surface water freshening is recorded in the planktonic foraminiferal δ18O data of deep-sea sediments across the JS (Oba et al. 1991).
This region is often cited as one of the most erosive landscapes identified globally, with annual yields of 20,000 to 40,000 t km−2 (World Bank 1998; USAID 1998), although Cox and others (2009) suggest more modest yields of 32 t km−2 y−1 estimated from cosmogenic Be data of river sediments.
Based on isotope data from the sediment of an ancient lake, the researchers suggest that the monsoon cycle, which is vital to the livelihood of all of South Asia, essentially stopped there for as long as two centuries.
The model is applied to geochemical data of regional stream sediments from the Funin Sheet, Yunnan, China.
