陆架浅海沉积物—海水界面上的溶解态生源物质通量的准确估算是海洋生态系统动力学研究中的关键性问题之一。
One of the key issues in the marine ecosystem dynamics studies is to accurately estimate the dissolved biogenic substance flux across the sediment-seawater interface in the shelf sea.
我们可以看到,现在的湖底或浅海底部的沉积物中形成了波痕。许多沉积岩都含有类似这种波痕的特征。
Many sedimentary rocks contain such features as ripple marks, exactly like those we can see forming in sediments at the bottom of present-day lakes or shallow seas.
它们在浅海的沉积物中扭来扭去,把猎物吞进袋状的微小躯体里,把水从嘴巴周围的圆锥形喷口排出去。
They wriggled around in the sediments of shallow seas, gulped prey into their minuscule, baglike bodies and expelled the water through cone-shaped spouts around their mouths.
