The invention provides a device having mechanical controls for rapid, accurate and easy sub-sectioning the aqueous sediments in the core liner from few millimeters to few centimeters along with any combination of the intervals. The device is useful to sub-section the sediments in the core liners without disturbing their physical and mechanical properties. The aqueous soft sediments can be either from near shore or deep-sea waters, and/ or from the fresh water river, lake, reservoir, lagoon, estuary, and creek environment, or from the areas of similar water bodies elsewhere and the like. A manually sliding sample holder on a perforated rod with a key and disk accessories enables rapid and precise sectioning of the sediments in the core liners without contamination and mixing, and saves extra time for core logging with minimum manpower and space requirement.
