一、引言 测量海水温度、盐度是海洋水文调查的主要任务。目前CTD仪(温盐深剖面仪)已广泛应用于海洋调查,与以往的温盐测量仪器相比,它具有操作简便、测量快速、能获取连续的海洋剖面资料的特点。 CTD资料质量的好坏,取决于调查和资料处理两个重要环节。调查过程包括出海前后标定、维护和保养、现场测量和比测等,要求有关技术人员严格遵守调查规范和仪器操作规程,确保原始资料质量;资料处理则是将原始资料进行技术校正和处理,它不仅可以提高资料的精度和质量,也为
I. INTRODUCTION Measurement of seawater temperature and salinity is the main task of ocean hydrological survey. At present, the CTD instrument (temperature and salinity deep profilometer) has been widely used in oceanographic surveys. Compared with the conventional thermostametry instruments, the CTD instrument has the advantages of simple operation, rapid measurement, and continuous continuous acquisition of oceanographic profile data. CTD data quality is good or bad, depends on the investigation and data processing two important aspects. The survey process includes calibration, maintenance and maintenance before and after going to sea, on-site surveying and ratio testing, etc., requiring the relevant technical personnel to strictly observe the survey norms and instrument operation rules and ensure the quality of the original materials; and the data processing adopts technical correction and processing of the original materials Not only can improve the accuracy and quality of information, but also
