| Abstract: | According to previous experiences in making sampling devices and some reference materials from abroad,we have developed a new-style device for taking lake sediment cores.This device may be used to collect lake sediment cores without disturbance,and the sediment-water interface can be kept distinct.The new sampling system is applicable to both deep and shallow lakes by various combination of the components.The maximum length of sediment cores increases from 80 cm to 150 cm.The practice has proved that this s... |
