gravity corer

A core 17.11 m long was successfully collected in an offshore experiment area with the newly designed corer, and the sampling rate achieved 91.3%, which created a collected core length record with the gravity piston corer in Chinese offshore geologic surveys.

海上实验在特定海区成功的获取了17.11m的长岩芯，取样率达91.3%，创造了我国海洋地质调查用重力活塞取样器获取岩心的最长记录。
