Study of Preprocessing Method of Oceanographic Hydrological Data

Based on analyzing of the process and task of preprocessing of oceanographic hydrological data,three main aspects,including the data preprocessing of Acoustic Doppler Profiler (ADP),quality control of data preprocessing and the recognition and processing method of abnormal hydrological data,are discussed.Theoretical reference is made for the post processing of hydrological data,and technical support for specialty development and expanding are also provided.
