Southeast Asia is particularly susceptible to the negative impacts of increasing coastal pollution as populations and cities grow at unprecedented rates. Although water chemistry can be monitored, there are greater advantages in using bioindicators reflectors combined effect multiple types on ecosystem health for early detection pollutants biotic systems. This study explores utility application...

Diatom distribution on continental shelf sediments from the upwelling area off Galicia (NW Iberian Peninsula) has been determined in 78 surface sediment samples. Three well defined biofacies with a close relationship to upwelling influence along the coast have been distinguished from both the absolute diatom abundances in the sediments and assemblage diatom composition based on multivariate sta...

biostratigraphy of bahram formation succession, with 359.8 meter thickness, in the sardar section (north of kerman, central iran) is done in this study. bahram formation is mostly composed of limestones (with a lesser amount of sandstones), and conformably overlies the top sandstone beds of the padeha formation. but, the upper boundary with the hutk formation (late tounaisian) is disconformable...
