Description

  The present invention relates to a hot water sampling device that collects hot water ejected from the seabed, for example.

  Substances such as products (emissions) in the subsurface biosphere on the sea floor are released as hot water into the ocean floor and diffuse into the ocean deep as a hydrothermal plume. Observing the behavior of this diffusion is useful because it will elucidate the physical and chemical reactions and microbial activities that occur in it and the effects they have on the ocean. In addition, collecting hot water released to the ocean floor as much as possible at the release position allows you to know the state immediately after the release, so that you can accurately grasp the discharge from marine organisms and the changes in the chemical environment of the organism itself. Connected and useful.

  When the hot water discharged to the ocean bottom layer is to be collected at the ejection site, for example, the heat of the ejection site can be remotely controlled by operating a manipulator from a working machine that performs work in the sea (for example, see Patent Document 1). It is conceivable to collect water.

  However, since the hot water released to the ocean floor reaches a high temperature of, for example, about 200 ° C. to 400 ° C., the state of the hot water immediately after discharge is predicted by collecting low-temperature seawater diffused from the ejection site. is the current situation. Even if the conditions such as the temperature of the hot water change slightly, the situation of the seawater changes remarkably, so it is important to directly collect the hot water immediately after discharge.
