| Description |
A modified hand-operated mechanical device has been developed to facilitate precise sectioning of the aqueous sediment in a core liner. The device allows the core liner to remain vertical on the disk protecting physical, chemical and mechanical properties of the sediment. The disk rotations are initially calibrated for moving unit distance on the threaded rod and later used proportionately for desired increment of the sediment. The sediment is exposed on the top of the liner when the disk and liner are lowered. A collapsible scale provided with the coupler on the top of the liner helps verify the required thickness of the sediment to be sectioned. Disk rotation does not cause compaction of sub-core sediment, and sub-samples are not mixed or contaminated. The apparatus is low-cost (< Rs 2000), portable, user-friendly, lightweight (about 9 kg) and occupies small floor area (0.25 sq. m). The apparatus is made up of non-magnetic and anti-rusting material for widescale application. It can be taken to the field or on a small boat or a research vessel, and quickly assembled and or dissembled. It is especially useful in a team with limited manpower. The core liners can be cleaned, washed and reused number of times, thus saving expenditure and making it environmental friendly.
