benthic

基本解释

Anything at or just below the surface of the seabed—the benthic zone, in fishery parlance—gets dragged up.
海底或僅僅在海底表麪下一點，用漁業的說法，就是深海底棲帶，任何生活在這裡的生物都會被拖上來。
The rub is that whereas there is little to confuse with a flicker of light in dark benthic recesses, any movement whatever will produce sounds.
而聲學探測的缺陷在於，盡琯在黑暗的深海底沒有什麽會乾擾到閃爍光，但是任何動靜都可能發出聲響。
Unfortunately, the cloud contains a lot of other stuff. Anything at or just below the surface of the seabed—the benthic zone, in fishery parlance—gets dragged up.
可惜，拖網還帶上來很多生活在深海區海牀表麪或下麪的其他生物，漁業術語叫做一網打盡。

Whale bones for example are known to constitute an excellent surface on which benthic communities deprived of local sources of energy can settle and develop.

Thus, the composition of benthic communities (the term indicates a dependency on the bottom) will rely partly on the availability of organic substances falling all the way down to the seabed.
