“…Отбор проб из трубки может осуществляться путем дозированного выдавливания керна поршнем. Другим вариантом отбора проб является заморозка материала в трубке, после чего замороженный керн распиливается на образцы [21]. Еще одной модификацией данной системы является гелификация осадка с использованием химических реагентов.…”

A new technology for coring of weakly consolidated sediment is proposed. The technology includes the original coring system and the way it is operated. The technology is based on a number of original solutions: 1) unification of the elements of the drill string, where household pipes made of PVC are used as a sampler and rods; 2) the use of the valve mechanism of a simple conical construction; 3) the method of vertical freezing of the core in open air. The coring system makes it possible to obtain the cores of the bottom sediment in winter from ice at a depth of up to 710 meters. Field tests have shown that the proposed system is inexpensive, easy to assemble and operate, but at the same time very effective and reliable. The new system can be as an alternative or complement to existing systems for coring of bottom sediments.
