Abstract: Disclosed is a container fixing holder of a time-series sediment trapping device. With respect to the container fixing holder of the time-series sediment trapping device, the time-series sediment trapping device includes a funnel; a frame disposed to support and surround the funnel, a frame having at least one rod vertically disposed and a fixing plate coupled to the at least one rod forming the frame on a horizontal plane defined by a lower portion of the funnel, wherein a rotation plate, to which a plurality of time-series sediment trapping containers to trap the time-series sediment collected through the funnel are fixedly attached, is formed under the fixing plate. The container fixing holder includes a circular holder for fixing the plurality of time-series sediment trapping containers fixedly attached to the rotation plate without shaking.

Abstract: Disclosed is a complex sampling apparatus. The complex sampling apparatus includes a main sampling unit having a predetermined weight to be sunk to sea floor and inserted into the sea floor in order to collect a sample including a sediment; one or a plurality of sub-sampling unit disposed at a side of the main sampling unit to detect that the sub-sampling unit arrives on the sea floor and to scrape a predetermined amount of the sample from a surface of the sea floor; and an image acquiring unit installed to the main sampling unit to acquire an image of the sea floor.
