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

This is raw Shipboard Acoustic Doppler Current Profiler (SADCP) 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2013年1月圣赫勒拿湾监测线船载多普勒声学流速剖面仪（SADCP）原始数据，该监测线隶属于综合生态系统计划（Southern Benguela）。圣赫勒拿湾监测线起源于由BENEFIT推动的“船载监测”项目，并与纳米比亚和安哥拉运行的相似监测线相衔接。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。此外，还将收集有关有害藻华、低氧水域以及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年起已存在长期的多十年时间序列信息，并持续以综合生态系统计划（IEP：SB）的形式收集，以监测水文和浮游生物的长期变化，这些变化对于识别环境变化至关重要。
