The relative amount of these two kinds of water varies greatly from one kind of rock or sediment to another, even though their porosities may be the same.

这两种水的相对含量在不同的岩石或沉积物之间差异很大，尽管它们的孔隙率可能是相同的。

One risk is that the mining operations could generate huge plumes of sediment that could drift through the sea - choking any marine life that feeds by ingesting water and filtering out its food sources.

Sediment-carrying rivers have been diverted, sea level has risen (increasing the volume of water in the lagoon), a deep-water channel has been dredged for shipping, and turbid waters are killing the eel grass that stabilises mud flats.

That will then be followed by the water sampling device - its descent captured live by HD cameras - and then the sediment corer.
