Calibration method for polar region pull-type ocean profile measuring instrument

The invention belongs to the technical field of marine environment monitoring, and discloses a polar region pull-type marine profile measuring instrument calibration method, which is characterized in that the gravity center position of an underwater profile buoy is quantitatively adjusted, so that the buoyancy moment and the gravitational moment are effectively adjusted, and the underwater profile buoy reliably ascends to the ice bottom and sinks to the preset depth. According to the method, each underwater profile buoy can be ensured to have the optimal floating gravity ratio and the optimal floating posture, and complete profile measurement data can be effectively obtained. Meanwhile, a force balance volume measurement method is adopted, a simple, convenient and rapid solution is provided for volume measurement of large buoys with irregular shapes, and the requirements of actual work in ocean engineering can be better met. 本发明属于海洋环境监测技术领域，公开了一种极地拖曳式海洋剖面测量仪定标方法，通过对水下剖面浮标重心位置进行定量调整，从而有效调整浮力矩和重力矩，实现水下剖面浮标可靠的上升
