海底沉积物中蕴藏着大量的微生物，这些微生物是人类认识和研究深渊生命演化及海底环境变化的重要途径，由于海底特殊的高压环境条件，在海底沉积物采集过程中必须尽可能减小微生物的外部环境压力的波动，避免外部压力的变化对嗜压微生物生命特征的影响，此外目前所采用的取样工具对不同深度的沉积物取样时，取出的沉积物放置在一个储存槽内，不能将其分开，在取样完成后升至海平面的过程中，取样器难免发生晃动，这就会造成不同深度的沉积物混在一起，不便于后期的研究，因此一种新型的取样设备应运而生。There are a large number of microorganisms in the seabed sediments. These microorganisms are an important way for humans to understand and study the evolution of life in the abyss and the changes of the seabed environment. Due to the special high-pressure environmental conditions of the seabed, the number of microorganisms must be minimized during the collection of seabed sediments. The fluctuation of external environmental pressure avoids the influence of external pressure changes on the vital characteristics of piezophilic microorganisms. In addition, when the currently used sampling tools sample sediments of different depths, the removed sediments are placed in a storage tank and cannot be stored. Separately, in the process of rising to sea level after sampling, the sampler will inevitably shake, which will cause sediments of different depths to be mixed together, which is not convenient for later research, so a new type of sampling equipment has emerged.
