Raw NDS data from the St Helena Bay Monitoring Line (SHBML) on the Algoa Voyage 195, March 2013

This is raw Network Data System (NDS) data from the St Helena Bay Monitoring Line, which now falls under the Integrated Ecosystem Programme: Southern Benguela, on the Algoa Voyage 196, 4 to 8 March, 2013.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.

本数据集源自圣赫勒拿湾监测线（NDS）的原始网络数据系统，该监测线现隶属于综合生态系统项目：南方本格拉地区，在196次阿尔戈阿航行中采集，时间为2013年3月4日至8日。圣赫勒拿湾监测线最初作为由BENEFIT项目驱动的“船载监测”项目启动，并与在纳米比亚和安哥拉运行的类似监测线相连接。其目的是获取该区域的水文和生产力季节性及年际信息。还将收集关于有害藻华、低氧水域以及阿古拉斯银行水侵入西海岸的数据。自1951年起，关于这一重要区域的信息已形成长期、多十年的时间序列数据，并继续以综合生态系统项目：南方本格拉地区的形式存在，以检测水文和浮游生物的长期变化，这对于检测环境状态的转变至关重要。
