UK Ocean Acidification Research programme data set

The cross-disciplinary themes will result in a diverse data catalogue. The ship collected data will be in the form of sea surface meteorology (2-D wind speed and direction, total irradiance, Photosynthetically Active Radiation/PAR, air temperature, atmospheric pressure, humidity); atmospheric carbon dioxide (pCO2); biological, chemical and physical properties and processes in the marine photic zone (carbonate chemistry - pCO2, total alkalinity, pH, DIC; dissolved gases - oxygen; nutrient concentrations, ammonium regeneration, nitrification, nitrogen fixation, zooplankon ecology, chlorophyll concentration, photosynthetic pigment composition, bacterial production, phytoplankton and bacterial speciation, concentrations of biogenic trace compounds such as dimethyl sulphide/DMS and dimthylsulphoniopropionate/DMSP, salinity, temperature, zooplankon ecology) and bioassays of these same parameters under different future IPCC CO2 and temperature scenarios. The long-term (18 month) laboratory based mesocosm experiments will include data on individual organism response (growth, immune response, reproductive fitness) under different future IPCC CO2 and temperature scenarios in rocky intertidal, soft sediment and calcareous biogenic habitats, as well as the effects on commercially important species of fish and shellfish. The analysis of sediment cores will provide greater resolution of the paleo record during the Paleocene-Eocene Thermal Maximum (PETM). Data will be used to aid the parameterisation of coastal and continental shelf seas (Northern Europe and the Arctic) model runs as well as larger scale global models. The shipboard fieldwork will take place around the UK, in the Arctic Ocean and the Southern Ocean. The mesocosms will look at temperate marine species common to UK shelf seas. Sediment cores have been collected from Tanzania. The models will look from the coastal seas of Northern Europe to the whole globe. Data to be generated will include data collected at sea, short-term (2-3 day) ship-board bioassays, from long-term (18 month) laboratory based mesocosm experiments and reconstructed paleo records from sediment cores. The 5 year UK Ocean Acidification Research Programme is the UK’s response to growing concerns over ocean acidification. Aims: 1 - to reduce uncertainties in predictions of carbonate chemistry changes and their effects on marine biogeochemistry, ecosystems and other components of the Earth System; 2 - to understand the responses to ocean acidification, and other climate change related stressors, by marine organisms, biodiversity and ecosystems and to improve understanding of their resistance or susceptibility to acidification; 3 - to provide data and effective advice to policy makers and managers of marine bioresources on the potential size and timescale of risks, to allow for development of appropriate mitigation and adaptation strategies. The study unites over 100 marine scientists from 27 institutions across the UK. It is jointly funded by Department for Environment, Food and Rural Affairs (Defra), the Natural Environment Research Council (NERC) and Department of Energy and Climate Change (DECC).

本跨学科主题将导致数据目录的多样性。船舶收集的数据将以海洋表面气象学（二维风速和风向、总辐照度、光合有效辐射/PAR、空气温度、大气压力、湿度）的形式呈现；大气二氧化碳（pCO2）；海洋光区内的生物、化学和物理特性及过程（碳酸盐化学 - pCO2、总碱度、pH值、DIC；溶解气体 - 氧气；营养物质浓度、铵再生、硝化作用、氮固定、浮游动物生态、叶绿素浓度、光合色素组成、细菌生产、浮游植物和细菌物种形成、二甲基硫化物/DMS和二甲基磺酰丙酸/DMSP等生物成因微量元素的浓度、盐度、温度、浮游动物生态）以及在不同未来IPCC CO2和温度情景下这些相同参数的生物测试。为期18个月的长期（18个月）实验室中生态系统实验将包括在岩石潮间带、软质沉积物和碳酸盐生物成因生境下，不同未来IPCC CO2和温度情景下个体生物对（生长、免疫反应、繁殖能力）的反应数据，以及这些变化对商业鱼类和贝类物种的影响。沉积物柱状样分析将提供在古新世-始新世热事件（PETM）期间古气候记录的更高分辨率。数据将被用于辅助参数化沿海和大陆架海（北欧和北极）模型运行以及更大规模的全球模型。船载现场工作将在英国、北极海洋和南大洋进行。中生态系统将研究在英国大陆架海中常见的温带海洋物种。已从坦桑尼亚收集沉积物柱状样。模型将研究从北欧沿海海到全球的整体情况。将生成的数据包括海上收集的数据、短期（2-3天）船载生物测试、长期（18个月）实验室中生态系统实验以及从沉积物柱状样中重建的古气候记录。为期5年的英国海洋酸化研究计划是英国对海洋酸化日益增长的关注所作出的回应。目标包括：1 - 减少对碳酸盐化学变化及其对海洋生物地球化学、生态系统和地球系统其他组成部分影响的预测不确定性；2 - 理解海洋生物、生物多样性和生态系统对海洋酸化及其他气候变化相关压力的反应，并提高对其对酸化抵抗性或易感性的理解；3 - 为政策制定者和海洋生物资源管理者提供数据和建议，以了解潜在风险的大小和时间尺度，从而允许制定适当的缓解和适应策略。该研究汇集了来自英国27个机构的100多名海洋科学家。该研究由环境、食品和农村事务部（Defra）、自然环境研究委员会（NERC）和能源与气候变化部（DECC）共同资助。
