Underway fCO2 measurements collected Dec 2012 (northbound leg) onboard the RTM Wakmatha on the Great Barrier Reef, Australia

Future Reef MAP is a three-year project designed to monitor ocean chemistry along the entire length of the Great Barrier Reef. It is a partnership between Rio Tinto Alcan, CSIRO and the Great Barrier Reef Foundation. The Future Reef Map Project is to develop the first large-scale CO2 observing system on the Great Barrier Reef (GBR) using the Rio Tinto ship, RTM Wakmatha. It is targeted at providing key information on the CO2 uptake in the region, the influence of the GBR reef complex on large-scale carbonate chemistry, and providing the foundation data needed to assess the vulnerability of the GBR reefs to ocean acidification. The repeat sampling from the ship will allow an assessment of controls and feedbacks on carbonate chemistry including the role of temperature change, freshwater inputs, and offshore-lagoon mixing in influencing carbonate chemistry and ocean acidification change. These data will be used for establishing the current status of the GBR with respect to net calcification and production (i.e. net growth or loss of reef material), and for identifying regional variability in the exposure of reef systems to ocean acidification. This dataset contains underway fCO2 measurements, atmospheric pressure, sea-surface temperature and salinity collected in December 2012 on the northbound leg of the voyage.

Future Reef MAP是一项为期三年的项目，旨在监测整个大堡礁沿线的海洋化学（ocean chemistry）状况。该项目由Rio Tinto Alcan、CSIRO与大堡礁基金会（Great Barrier Reef Foundation）合作开展。Future Reef Map项目将利用力拓集团（Rio Tinto）的RTM Wakmatha号船舶，开发首个覆盖大堡礁（Great Barrier Reef，GBR）的大规模二氧化碳（CO₂）观测系统。项目旨在提供该区域二氧化碳吸收量的关键信息、大堡礁珊瑚礁群对大规模碳酸盐化学（carbonate chemistry）的影响，并为评估大堡礁珊瑚礁对海洋酸化（ocean acidification）的脆弱性提供所需的基础数据。通过船舶重复采样，可评估碳酸盐化学的控制因素与反馈机制，包括温度变化、淡水输入及离岸-泻湖混合作用对碳酸盐化学与海洋酸化变化的影响。这些数据将用于确定大堡礁在净钙化（net calcification）与生产（即珊瑚礁物质净增长或流失）方面的当前状态，并识别珊瑚礁系统受海洋酸化影响的区域差异。本数据集包含2012年12月航行北向航段期间收集的航行中海水二氧化碳分压（fCO₂）测量数据、大气压力（atmospheric pressure）、海表温度（sea-surface temperature）及盐度（salinity）数据。
