The benthic chamber is used to analyze a type of various microorganisms growing in seawater adjacent to the sea floor and various gas components or chemical components generated by ecological activities of epizoite which attaches to or crawls on a settlement layer of a sea floor or infauna which enters and inhabits a tidal mudflat or a sandy beach providing a settlement layer. More particularly, a culture chamber constituting the benthic chamber is connected and installed on an apparatus structure of a measuring device by a hinge rod in a link manner, meanwhile, an angular motion device capable of lifting the hinge rod upward by a predetermined angle together with the culture chamber is installed on the apparatus structure of the measuring device. Thus, a lower end of the culture chamber of which a bottom surface is open is inserted into the sea floor by a predetermined depth, and then, one measurement is performed in a manner of rotating an impeller inside the culture chamber to disturb a settlement layer of the sea floor. Then, as the culture chamber is lifted from the sea floor together with the hinge rod using the angular motion device, a settlement layer at a corresponding position is stabilized over a certain period of time. Then, by lowering the culture chamber back to its original position, the measurement is performed again. Therefore, the in situ culture benthic chamber is capable of performing continuous settlement layer measurement on a sea floor.

Description

In situ benthic chamber possible for continuous measurement on the seafloor}

The present invention is provided in a measuring device that collects samples or data for environmental measurement necessary for ecological research on the sea floor, and is attached to the sediment layer of the sea floor or crawling vegetation or entering the tidal flat or sandy beach forming the sediment layer and inhabit. It relates to an on-site culture bentic chamber used to analyze various gas components or chemical components generated by the ecological activities of endogenous organisms, and the types of various microorganisms growing in seawater adjacent to the sea floor.

In general, various studies on the ecology of the seafloor in coastal waters where the bottom surface is composed of sedimentary layers such as tidal flats or sandy beaches is conducted to the inside of the sedimentary layers of the seafloor or vegetative organisms that adhere or crawl on the surface of the sedimentary layer on the seabed. It is carried out based on analysis of various gas components or chemical components generated as a result of ecological activities of endogenous (internal books) organisms that enter and inhabit, and the types of various microorganisms that grow in the seawater in the depth of the sea floor adjacent to the seafloor.

In addition, in the study on the pollution status of the sea floor caused by various foreign substances introduced from the land and the activity status of superficial or endogenous organisms resulting from this, the seawater in the depth layer adjacent to the sea floor is collected as a sample and the sample is analyzed. In the most preferable way, in a state in which the culture chamber with an open bottom is inserted to a certain depth through the seabed, the impeller inside the culture chamber is rotated to disturb the sediment layer at the corresponding location, and then Gas components or chemical components are measured with a sensor device over a reaction time, while reactive seawater trapped inside the culture chamber is collected by time.

As described above, it is a measuring device for collecting samples or data for environmental measurement necessary for seabed ecology research in coastal waters.It was developed by the present inventor at the time of his tenure at the National Fisheries Research Institute, and was first applied for patent application No. 56606 and registered a patent (No. 10 -0925885) is a representative example of a sampling device for collecting seawater samples, and the sampling device constitutes a Benthic chamber with a culture chamber, an impeller, and a sensor device described above, and takes a seawater sample from the culture chamber. A sample collector for collecting water by time and a control mechanism for controlling the device and storing data are installed on the device frame together with the ventic chamber.

However, in the case of the ventic chamber applied to the conventional sampling device as described above, since the culture chamber is fixedly installed under the central part of the device frame that provides the basis of the sampling device, the corresponding sampling device is mounted on the sea floor to prevent the culture chamber. The bottom side of the cultivation chamber is inserted into the seabed by a predetermined depth, and then the impeller inside the culture chamber is rotated to disturb the sediment layer at the location. After the first completion of the seawater sample collection operation, there was a problem in that it was impossible to perform additional water collection and measurement operations using a ventic chamber.

In other words, after the conventional sampling device is mounted on the sea floor, measurement of gas components or chemical components and sampling of seawater samples that can be performed through the ventic chamber are disturbed by the impeller with seawater inside the culture chamber. It means that the sediment layer is limited to the result of one batch produced through the reaction with seawater, and after the first measurement and collection work are completed through the reaction process, the seawater trapped inside the culture chamber itself loses its value as a sample. Therefore, the additional measurement work through the ventic chamber or the work of collecting seawater samples is meaningless.

Due to the above factors, not only the measurement data that can be obtained by inputting a sampling device, which is an expensive measurement equipment, to the sea floor once, and the range and diversity of seawater samples have been greatly reduced, but also the measurement data and There was a problem that the accuracy of the analysis work using seawater samples and the reliability of the research results were also greatly degraded, and for the purpose of supplementing this, simply repeatedly performing the operation of inputting and recovering the sampling device to the sea floor several times Considering the characteristics of the operation of the ship and the work required by professional manpower, there was an extremely inefficient and inefficient problem.
