St Helena Bay Monitoring Line (SHBML) on the Africana Voyage 234, July 2007

This St Helena Bay Monitoring Line (SHBML) cruise was conducted on the Africana Voyage 234 in July 2007. 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2007年7月进行于非洲航次234号。该航线为长期监测航线，位于南非西海岸的伊兰兹/圣赫勒拿湾沿海地区。SHBML始于2000年，作为一项由BENEFIT项目驱动的“船载监测”项目，与纳米比亚和安哥拉运行的类似航线相衔接。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。2013年，该项目被纳入综合生态系统计划：南方本格拉（IEP：SB），旨在巩固自1951年以来关于这一重要区域长期、多十年时间序列的信息，并继续以IEP：SB的形式进行监测。该计划是一个多学科、协作和人才培养平台，承担相关科学研究，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、海底以及污染（塑料）生态系统指标，符合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。目前，该监测项目仍在进行中。
