AN IN SITU GAS-TIGHT PORE WATER SAMPLER FOR DEEP-SEA SEDIMENTS

摘要: 报道了一种新研制的深海沉积物孔隙水原位气密采样器,详细介绍了该采样器的结构构造、设计特点及工作原理。实验室模拟和海上试验显示,该采样器可成功进行海底沉积物孔隙水的原位气密采集;采样器工作水深范围500~4 200 m,沉积物采样深度3~5.5 m,一次可采集11瓶孔隙水,每瓶最小采水量大于100 mL。

Abstract: This paper presents a new-developed in situ gas-tight pore water sampler for deep-sea sediments,particularly introducing its configuration,feature and working principle.Marine tests and laboratory simulations showed that the sampler was able to be employed to sample pore water of the seafloor sediments with thicknesses of 3~5.5 m,at water depths between 500 and 4 200 m under the sea,and can simultaneously obtain 11 bottles of pore water,each of which is more than 100 mL at volume.
