摘要： PROBLEM TO BE SOLVED: To obtain an underwater water sampler by which a plural kinds of water samples can be obtained, even from places with different depths in one loading and collecting operation. SOLUTION: In an underwater water sampler, an underwater pump 9 is connected to an airtight container 1 in which a plurality of water sampling bags 3A, 3B,... composed of a flexible film are housed and which communicates with the outside via a container opening and closing implement 5, and sampling tubes 6A, 6B,... which are connected to the respective water sampling bags 3A, 3B,... communicate with the outside via respective sampling opening and closing implements 4A, 4B,.... Then, before the underwater pump 9 is operated, the container opening and closing implement 5 is closed, and at least one out of the sampling opening and closing implements 4A, 4B,... is opened. In synchronization with the operation stop of the underwater pump 9, the container opening and closing implement 5 is opened, and the sampling opening and closing implements 4A, 4B,... are closed.
