benthic

基本解釋

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(diǎn)，用漁業(yè)的說(shuō)法，就是深海底棲帶，任何生活在這裡的生物都會(huì)被拖上來(lái)。
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(xué)探測(cè)的缺陷在於，盡琯在黑暗的深海底沒(méi)有什麼會(huì)乾擾到閃爍光，但是任何動(dòng)靜都可能發(fā)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(wǎng)還帶上來(lái)很多生活在深海區(qū)海牀表麪或下麪的其他生物，漁業(yè)術(shù)語(yǔ)叫做一網(wǎng)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.
