trawl

The oil industry uses supercomputers to trawl seismic data before drilling wells..石油公司可以在钻井之前先拖网分析地震数据。

The new analysis used catch data as well as stock assessments, scientific trawl surveys, small-scale fishery data and modelling results..这项新研究利用捕捞量、种群评估、科学的拖网调查、小规模渔业数据以及模型进行分析。

But when you go to a tropical rainforest, it's easy to find new insects, and when you go to the deep sea and pull up a trawl, 90% of what you get can be undiscovered species..但是当进入热带雨林后，我们很容易就能发现新种类的昆虫；进入深海区域洒下一张拖网，你捕获的生物有90％是未被发现过的物种。
