CCS - MV Bluefin 2017 V01 CTD

Project Overview: A range of solutions will be required to reach globally agreed emissions reductions targets for carbon dioxide (CO2). Carbon capture and storage (CCS) is part of the suite of technologies that will contribute to lowering atmospheric emissions of CO2 from Australia's energy system. There are a wide variety of technologies at various stages of technical and commercial readiness, with more development underway for cost effective CO2 capture and storage. Our research will provide new knowledge to inform cost-efficient measurement, monitoring and verification (MMV) of the environment of CCS projects in coastal waters.\n\n--o--\n\nBrief Description:\nA series of CTD casts were completed using a SBE25plus CTD profile combined with Seabird ECO55 water sampler accommodating six Niskin bottles. Water samples were taken from each cast using pre-programmed depths appropriate to the total water column depth which varied from 14 -20 m. Niskin bottles were closed on the down cast due to limitations of the firing software. The water temperature ranged between 18 and 20 degrees. Oxygen and nutrient samples were taken from most of the successful Niskin bottles samples. \n\nThe first three CTD casts were found to have the wrong time stamp as the CTD had been initialised in local time. This was corrected to UTC and the metadata for the casts updated.\n\nRelevant component details: make, model, serial number, firmware version, settings:\n\nSensor | Serial Number\nSBE25plus | 0251152\nTemperature | 03-6206\nConductivity | 04-4632\nPressure | 10654713\nOxygen Sensor (SBE 63) | 1669\nWet labs (ECO-BB ) | BBFL2BAC-1204

项目概述：实现全球公认的二氧化碳（CO₂）减排目标需要一系列解决方案。碳捕获与封存（Carbon Capture and Storage, CCS）是澳大利亚能源系统降低大气CO₂排放的技术组合之一。各类技术处于不同的技术与商业就绪阶段，目前正开展更多研发以实现经济高效的CO₂捕获与封存。本研究将产出新知识，为沿海CCS项目环境的成本优化型测量、监测与核查（Measurement, Monitoring and Verification, MMV）提供依据。

简要描述：
采用SBE25plus CTD剖面仪结合配备六个Niskin瓶的Seabird ECO55水样采集器，完成了一系列CTD剖面测量。水样从每个剖面的预编程深度采集，深度根据总水柱深度（范围14-20米）设定。受触发软件限制，Niskin瓶于下行剖面过程中关闭。水温范围为18至20摄氏度。大部分成功采集的Niskin瓶样本中提取了氧气与营养盐样本。

前三次CTD剖面测量发现时间戳错误（因CTD初始化为当地时间），已修正为UTC并更新剖面元数据。
