AIMS Sea Water Temperature Observing System (AIMS Temperature Logger Program)

The data provided here are from a number of sea water temperature monitoring programs conducted in tropical and subtropical coral reefs environments around Australia. Data are available from approximately 80 GBR sites, 16 Coral Sea sites, 7 sites in North West Western Australia (WA), 8 Queensland regional ports, 13 sites in the Solitary Islands, 4 sites in PNG and 10 sites in the Cocos (Keeling) Islands. Data are obtained from in-situ data loggers deployed on the reef. Temperature instruments sample water temperatures every 5-10 minutes (typically) and are exchanged and downloaded approximately every 12 months. Temperature loggers on the reef-flat are generally placed just below Lowest Astronomical Tide level. Reef-slope (or where specified as Upper reef-slope) generally refers to depths 5 - 9 m while Deep reef-slope refers to depths of ~20 m.

Reefs are under threat from climate change. Elevated sea temperature is a major stress to reefs, capable of causing widespread coral bleaching and mortality. Small excursions of temperature outside normal summer levels can cause stress and bleaching in corals, especially sensitive species. Temperature data from this program are used to correlate with bleaching events and derive local bleaching thresholds. Data are also used in a wide variety of other marine research programs, including fisheries, balast water, turtles, sea birds, seagrass, coral disease, oceanography, process studies, validation of proxy climate records etc.

本数据集所用数据源自澳大利亚周边热带、亚热带珊瑚礁海域开展的多项海水温度监测项目。数据覆盖约80个大堡礁（Great Barrier Reef, GBR）监测点、16个珊瑚海监测点、西澳大利亚州西北部的7个监测点、8个昆士兰州区域港口监测点、13个索利塔尔群岛监测点、4个巴布亚新几内亚（Papua New Guinea, PNG）监测点以及10个科科斯（基林）群岛监测点。所有数据均来自部署于珊瑚礁上的原位数据记录仪（in-situ data loggers）。温度仪器通常每5至10分钟采集一次海水温度数据，每约12个月进行一次设备更换与数据下载。礁坪上的温度记录仪一般安装在天文最低潮位下方。礁坡（或标注为上礁坡）通常指代水深5至9米的区域，而深礁坡则指代水深约20米的区域。

珊瑚礁正面临气候变化带来的多重威胁。海水温度升高是珊瑚礁面临的主要胁迫因子之一，可引发大范围珊瑚白化与死亡。即使海水温度小幅偏离夏季正常水平，也可能对珊瑚（尤其是敏感物种）造成胁迫并诱发白化现象。本项目获取的温度数据可用于关联珊瑚白化事件，并推导当地白化阈值。此外，这些数据还可应用于众多其他海洋研究项目，涵盖渔业、压载水、海龟、海鸟、海草、珊瑚病害、海洋学、过程研究以及代用气候记录验证等多个领域。
