项目摘要
The project will build and validate a set of 6 pH and nitrate sensors for profiling floats that will be deployed in the Southern Ocean. These sensors, from MBARI, will be integrated with floats supplied by the University of Washington Float lab. In addition to the pH and oxygen sensors, the floats will also carry fluorescence optode oxygen sensors together with biooptical sensors for chlorophyll fluorescence and backscatter. Each float will operate for approximately 330 profiles from 1700 m depth to the surface. This should equate to a 5 year endurance at profiling intervals near 7 days. The profiling floats will be deployed along the decadal CLIVAR P16S cruise, scheduled to leave New Zealand in March 2014. The P16S line will go north from the ice edge along 150 degrees W. Three of the floats with chemical sensors will be deployed at latitudes where there should be seasonal ice cover and three will be deployed to the north of the ice covered ocean.The pH data collected by the floats should provide one of the first records of the annual cycle of pH in a region that is expected to become undersaturated with aragonite as atmospheric CO2 continues to increase. This will allow a unique assessment of the ability of current generation climate models to predict ocean pH trajectories.
该项目将建造并验证一套 6 个 pH 值和硝酸盐传感器,用于剖面浮标,这些浮标将部署在南大洋。这些来自 MBARI 的传感器将与华盛顿大学浮子实验室提供的浮子集成。除了 pH 值和氧气传感器外,浮标还将携带荧光光极氧气传感器以及用于叶绿素荧光和反向散射的生物光学传感器。每个浮标将从 1700 米深度到水面运行约 330 个剖面。这应该相当于 5 年的耐久性(分析间隔接近 7 天)。剖面浮标将沿着十年期 CLIVAR P16S 巡航部署,计划于 2014 年 3 月离开新西兰。P16S 线将从冰缘沿西经 150 度向北延伸。三个带有化学传感器的浮标将部署在应有季节性冰覆盖的纬度,另外三个将部署在冰覆盖海洋的北部。浮标收集的 pH 数据应提供第一批数据之一。 记录了该地区 pH 值的年度循环,随着大气中二氧化碳的持续增加,该地区文石预计将变得不饱和。这将对当前一代气候模型预测海洋 pH 值轨迹的能力进行独特的评估。
