    摘要： The present invention relates to a bottom sampler comprising, a cable connecting plate, an outer fixing plate disposed at a lower side of the cable connecting plate, a sample barrel guide extending downwards from the outer fixing plate, and a sample barrel configured to have a sediment permeation prevention plate mounted at an outer peripheral end, and provided with a valve at opposite ends, the valve connected to a guide rod pivotally coupled to a first end of a lever operating arm, wherein the valve is closed depending on the pivoting of the lever operating arm when a seabed sample is introduced into the sample barrel to seal an inner part thereof. Accordingly, seabed samples such as gas-filled sediments can be collected and analyzed without pressure leakage.
