Raw NDS data from the St Helena Bay Monitoring Line (SHBML) on the Algoa Voyage 193, January 2013

This is raw Network Data System (NDS) data from the St Helena Bay Monitoring Line January 2013 cruise (now under the Integrated Ecosystem Programme: Southern Benguela). The St Helena Bay Monitoring Line was initiated as a BENEFIT-driven project on "shipboard monitoring" which linked with similar lines run in Namibia and Angola. The aims are to obtain seasonal and interannual information on the hydrology and productivity of the area. Data on harmful algal blooms, low oxygen water and intrusions of Agulhas Bank water along the west coast will also be collected. A long-term, multi-decadel time-series (from 1951 onward) of information already exists for this important region and has continued in the form of the IEP:SB to detect long-term changes in the hydrology and the plankton, which are important for the detection of regime shifts.

此为圣赫勒拿湾监测线（St Helena Bay Monitoring Line）2013年1月巡航所采集的原始网络数据系统（Network Data System，简称NDS）数据，目前该监测线隶属于综合生态系统计划（Integrated Ecosystem Programme，简称IEP）的南方本格拉区域。圣赫勒拿湾监测线项目起源于以“船载监测”为驱动的BENEFIT项目，并与在纳米比亚和安哥拉运行的类似监测线相连接。项目旨在获取该区域的水文和生产力季节性及年际变化信息。同时，还将收集有关有害藻华、低氧水体以及阿古拉斯银行水体沿西海岸入侵的数据。对于这一重要区域，自1951年起已存在长期的多十年时间序列信息，并持续以IEP:SB的形式存在，旨在检测水文和浮游生物的长期变化，这些变化对于检测系统状态的转变至关重要。
