Annual fluxes of diatom frustules in these trap samples, and in surface sediments collected beneath the sediment trap, were analyzed and compared with each other to investigate the ecology and taphonomy of marine planktonic diatoms. Calculated annual fluxes of marine

There were four major stages for the development of the Yangtze River ...

The core samples mostly consist of non-glacial varved sediments and massive clay and silt, including volcanic ash layers. We ...
