Underway fCO2 measurements collected April 2014 onboard the RTM Wakmatha on the Great Barrier Reef, Australia.

Data were collected as part of the FutureReef MAP project, a three-year project designed to monitor ocean chemistry along the entire length of the Great Barrier Reef. The Future Reef MAP project is funded by Rio Tinto Alcan and administered by the Great Barrier Reef Foundation, with an equal co-investment by CSIRO. The project is the first large-scale CO2 observing system established on the Great Barrier Reef using the Rio Tinto ship, RTM Wakmatha. The research is targeted at providing information on the CO2 uptake and the controls on ocean acidification change in the region. It is providing foundation data needed to assess the vulnerability of the GBR reefs to ocean acidification. This dataset contains quality controlled underway measurements of the fugacity of CO2, atmospheric pressure, and sea surface temperature and salinity. The data management and distribution of these data were supported by the CSIRO Carbon Collaboration Cluster and the Australian Coastal Ecosystem Facility.

本数据集的数据采集工作依托FutureReef MAP项目开展，该项目为期三年，旨在全程监测大堡礁沿线的海洋化学状况。本项目由力拓铝业（Rio Tinto Alcan）资助，大堡礁基金会（Great Barrier Reef Foundation）负责管理，并由澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation，缩写CSIRO）提供等额联合投资。本项目是首个在大堡礁海域搭建的大型二氧化碳观测系统，搭载力拓旗下RTM Wakmatha号科考船执行观测任务。本研究旨在获取该区域二氧化碳吸收情况以及海洋酸化变化调控机制的相关数据，为评估大堡礁珊瑚礁对海洋酸化的脆弱性提供基础支撑数据。本数据集包含经过严格质量控制的走航观测数据，涵盖二氧化碳逸度（fugacity of CO₂）、大气压强、海表温度及盐度等参数。本数据集的管理与分发工作得到了CSIRO碳协作集群（Carbon Collaboration Cluster）以及澳大利亚沿海生态系统设施的支持。
