海底采样仪器是进行海洋地质调查获得海底沉积物样品的基本设备。近百年来,在海洋地质工作者的努力下,先后研制、改进了数以百种的底质采样仪器。归纳起来,可分拖曳式采样器、表层采样器和桂状采样器三大类。本文就具有代表性的且广泛使用的采样仪器作一般介绍。 Submarine sampling equipment is the basic equipment for marine sediment samples for marine geological survey. Over the past century, with the efforts of marine geologists, they have successively developed and improved hundreds of bottom sediment sampling instruments. To sum up, can be divided into drag-type sampler, surface sampler and Gui-like sampler three categories. This article gives a general introduction to a representative and widely used sampling instrument.
