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

This is raw Shipboard Acoustic Doppler Current Profiler (SADCP) 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.

本数据集为圣赫勒拿湾监测线原始船载多普勒声学流速剖面仪（SADCP）数据，该监测线目前隶属于综合生态系统项目：南本格拉区域，采集于2013年3月4日至8日的Algoa航行196次。圣赫勒拿湾监测线起源于由BENEFIT项目驱动的“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。项目旨在获取该区域水文和生产力方面的季节性和年际信息。同时，还将收集有害藻华、低氧水体以及阿古拉斯银行水体沿西海岸侵入的相关数据。对于这一重要区域，自1951年起已存在长期、多十年时间序列的信息，该信息通过综合生态系统项目：SB（IEP:SB）的形式持续更新，以监测水文和浮游生物的长期变化，这些变化对于检测系统转变至关重要。
