Carbon isotope ratios of organic matter in Bering Sea settling particles: Extremely high remineralization of organic carbon derived from diatoms
diatoms coccolithophores carbon isotope organic carbon remineralization rain ratio
2017/4/10
The carbon isotope ratios of organic carbon in settling particles collected in the highly-diatom-productive Bering Sea
were determined. Wet decomposition was employed to oxidize relatively fresh orga...

The contribution of hyperspectral remote sensing to identify vegetation characteristics necessary to assess the fate of Persistent Organic Pollutants (POPs) in the environment
hyperspectral imaging species distribution LAI semi-empirical model POPs
2015/9/7
During recent years hyperspectral remote sensing data were successfully used to characterise the state and properties of vegetation. The information on vegetation cover and status is useful for a rang...
The Dissolved Organic Carbon Controversy:An Update
Dissolved Organic Carbon Controversy An Update
2015/8/19
This note is intended as an update on activities to improve the measurement of dissolved organic carbon (DOC) in seawater. The exciting and controversial paper by Sugimura and Suzuki (1988) led to ren...
