St Helena Bay Monitoring Line (SHBML) on the Algoa Voyage 091, February 2001

This St Helena Bay Monitoring Line (SHBML) cruise was conducted on the Algoa Voyage 091 in February 2001. This is a long-term monitoring line conducted off the coast of Elands/St Helena Bay on the west coast of South Africa. SHBML started in 2000 as a BENEFIT-driven project on "shipboard monitoring" which linked with similar lines run in Namibia and Angola. The aims were to obtain seasonal and interannual information on the hydrology and productivity of the area. It was incorporated under the Integrated Ecosystem Programme: Southern Benguela (IEP:SB) in 2013 consolidating a long-term, multi-decadal time-series (from 1951 onward) of information for this important region and has continued monitoring in the form of the IEP:SB. The programme is a multi-disciplinary, collaborative and capacity building platform undertaking relevant science, including updating technology, with the aim to develop ecosystem indicators that can be used to effectively monitor and understand the Southern Benguela. These include physical, chemical, planktonic, microbial, seabird, marine mammal, benthic and pollution (plastic) ecosystem indicators as required by ecosystem-based management regarding the following priorities: ocean warming, ocean acidification, trophic functioning, pollution and water quality. It is on-going monitoring programme.

此次圣赫勒拿湾监测航线（SHBML）巡航于2001年2月由Algoa航次091执行。该航线系一项长期监测项目，位于南非西海岸的埃兰兹/圣赫勒拿湾沿海。SHBML始于2000年，作为一项以BENEFIT为驱动力的“船载监测”项目，与在纳米比亚和安哥拉运行的相似航线相衔接。其目标是获取该区域的水文和生产力季节性及年际变化信息。2013年，该项目纳入综合生态系统计划：南方本格拉（IEP:SB），从而巩固了自1951年以来的长期、多十年时间序列信息，并继续以IEP:SB的形式进行监测。该计划是一个多学科、协作和能力建设平台，承担相关科学任务，包括更新技术，旨在开发可用于有效监测和理解南方本格拉生态系统的生态系统指标。这些指标包括物理、化学、浮游生物、微生物、海鸟、海洋哺乳动物、底栖和污染（塑料）生态系统指标，以满足基于生态系统的管理要求，针对以下优先事项：海洋变暖、海洋酸化、营养功能、污染和水质量。这是一项持续进行的监测项目。
