Underway fCO2 measurements collected Feb 2013 (southbound leg) 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项目展开，该项目为期三年，旨在全程监测大堡礁沿线的海洋化学环境。FutureReef MAP项目由力拓铝业（Rio Tinto Alcan）资助，大堡礁基金会（Great Barrier Reef Foundation）负责运营管理，并由澳大利亚联邦科学与工业研究组织（CSIRO）提供等额联合投资。本项目是大堡礁首个借助力拓科考船"RTM Wakmatha"搭建的大规模二氧化碳（CO₂）观测系统。研究目标为获取该区域二氧化碳吸收情况与海洋酸化变化调控机制的相关数据，可为评估大堡礁珊瑚礁对海洋酸化的脆弱性提供核心基础数据。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。上述数据的管理与分发工作得到了CSIRO碳合作集群与澳大利亚沿海生态系统设施的支持。
