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

This is raw Conductivity, Temperature, Depth (CTD) 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.

本数据集为圣赫勒拿湾监测线2013年1月巡航的原始电导率、温度、深度（CTD）数据，现隶属于综合生态系统计划：南本格拉区。圣赫勒拿湾监测线作为由BENEFIT项目驱动的“船载监测”项目而启动，与纳米比亚和安哥拉运行的类似线路相衔接。其目标在于获取该区域的水文和生产力季节性及年际信息。同时，还将收集有害藻华、低氧水和阿古拉斯银行水入侵西海岸的数据。对于这一重要区域，自1951年起已存在一个长期的多十年时间序列信息，该信息以综合生态系统计划：南本格拉区的形式持续更新，旨在检测水文和浮游生物的长期变化，这些变化对于检测环境状态的转变至关重要。
