The large-diameter sediment column sampling system it developed has recently completed sea trials and verification in the southern waters of the Yellow Sea. The system adopts an operating mode of vertical retraction, online communication control, visualization, and equipped with multiple types of underwater sensors.
It worked stably during the test, with a single sampling length of up to 7.89 meters, and collected data from the low sea level period since the Last Glacial Maximum. It is mainly used for archaeological research on buried ancient human sites on the continental shelf.
