HM2000型剖面浮标的主要特征及其应用

Main Characteristics and Applications of HM2000 Profile Float

摘要:

HM2000 型剖面浮标是一种新颖的国产海洋观测仪器,可以长期在海上自由漂移并连续测量 0~2 000 m 水深内的海水温、盐度剖面数据,已被国际 Argo 组织用于全球 Argo 实时海洋观测网建设和维护。 详细介绍了该型浮标的工作原理、结构、功能和主要技术指标等,并与 APEX 型浮标进行了比较分析, 表明了 HM2000 型剖面浮标具有明显的功能优势,且测量的温、盐度质量是有足够保证的,完全可以替代国外浮标用来主导建设我国的 Argo 区域海洋观测网。

Abstract:

HM2000 profile float is a domestic novel marine observation equipment. It drifts automatically in a long term and measures the temperature and salinity profile data of seawater from sea surface to 2 000 m depth. HM2000 float has been approbated by the International Argo Project and applied to the construction and maintenance of the Global Argo Real-time Ocean Observing Network. This paper introduces the working principle, structure, function and main specifications of the float, and makes a brief comparative analysis with the APEX float. The results show that the HM2000 profile float has apparent functional advantages, and the profile data are credible and accurate. Therefore, HM2000 profile float can replace imported floats to dominate Chinese Argo re- gional ocean observation network
