一种近海底层防渔业拖网多参数监测平台的研制与应用

A Kind of Trawl-Resistant Bottom Mount for Multi-Parameter Monitoring:Development and Application

介绍了一种近海底层防渔业拖网多参数监测平台的设计、组成与海上应用情况。平台设计上兼顾了工作的安全性和测量的多功能性,通过对浮体加工、仪器布局、平台集成和布放、回收等技术的研究,完成了此平台的研制。平台适用于我国150 m以内的浅海域进行2个月以内的多学科水质参数连续监测,它可同时搭载1个海流计、1个多参数水质仪、1个营养盐仪、2个声学释放器和1个电池筒。平台至今在我国东海已布放使用20站次,其中一半以上集中在长江口海域进行底层缺氧现象相关水质参数的监测。2009和2011年夏季长江口北部海域站点监测实况表明,平台在防渔业拖网性能方面表现良好,仪器测量在"梅花"台风正面冲击时未受明显影响。

This paper introduces a kind of trawl-resistant bottom mount（TRBM） for multi-parameter monitoring in the aspects of system design, structure and application in coastal areas. The platform design strikes a balance between operational safety and multi-functional observations. This platform was accomplished by developing the technologies of floating body machining, instrument layout, system integration, deployment and reclamation. It is suitable for continuous monitoring on multi-disciplinary water quality parameters in coastal areas shallower than150 m within 2 months by mounting instruments, including 1 ADCP, 1 CTD, 1 nutrient sensor, 2 acoustic releasers and 1 battery pack. This TRBM has been deployed 20 times in the East China Sea, and was often used to acquire the multi-disciplinary parameter data relative to bottom hypoxia off the Yangtze River estuary. The monitoring data in summers of 2009 and 2011 off the northern Yangtze River estuary show that the TRBM has good trawl-resistant performance, and its carried measuring instruments were not obviously impacted by the Typhoon ＂Mei Hua＂.
