Raw CTD data from the St Helena Bay Monitoring Line (SHBML) on the Algoa Voyage 194, February 2013

This is raw Conductivity, Temperature, Depth (CTD) data from the St Helena Bay Monitoring Line February 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2013年2月圣赫勒拿湾监测线（现隶属于综合生态系统计划：南方本格拉湾）的原始电导率、温度和深度（CTD）数据。圣赫勒拿湾监测线起源于由BENEFIT驱动的“船载监测”项目，该项目与纳米比亚和安哥拉运行的类似监测线相衔接。其目标在于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、低氧水以及阿古拉斯银行水侵入西海岸的数据。针对这一重要区域，自1951年起已存在一个长期、多十年时间序列的信息，这些信息以综合生态系统计划：南方本格拉湾的形式持续更新，旨在检测水文和浮游生物的长期变化，这对于识别系统状态的转变至关重要。
