Inorganic Carbon Measurements on the 2010/2011 North Atlantic GEOTRACES Cruise

这项快速反应研究赠款是向百慕大海洋科学研究所的一个研究小组提供的，以满足美国GEOTRACES北大西洋区域调查科对海水无机碳测量的迫切需要。由于研究船发生严重机械故障，2010年底中止了第一次航行;北大西洋研究的其余部分已重新安排，将于2011年10月恢复航行。在与迈阿密大学的其他GEOTRACES同事的合作下，BIOS团队的工作重点将是收集溶解无机碳（DIC）和总碱度（TA）的样本，对这些样本进行实验室分析，并随后将这些数据集夹带/合并到美国GEOTRACES北大西洋分区调查部分核心水文学/瓶数据集分发给项目研究人员和更广泛的科学界。 本次航行将总共采集600份样本，其中300份样本在BIOS进行分析，300份样本在RSMAS进行分析。在2010年中止的巡航中收集了大约200个样本，一旦返回各自的实验室，将对DIC和TA进行分析。在2011年恢复的GEOTRACES巡航中将收集更多样本，在各自的实验室中对样本进行分析，整个数据集将接受标准QC/QA协议。更广泛的影响。 人们普遍认为，海洋生物地球化学研究界需要对GEOTRACES的关键和辅助性质有一个全球性的认识。该项目的主要影响将是通过测量无机碳对美国GEOTRACES北大西洋区域调查部分的贡献。这广泛有助于提高对北大西洋无机碳循环的认识。虽然没有研究生获得资助，但该奖项将支持两名研究技术人员提高技能，并将数据纳入BIOS的日本基金会POGO卓越中心关于海洋碳循环的教学模块。

This Grant for Rapid Response Research (RAPID) is being made to a research team at the Bermuda Institute for Ocean Sciences (BIOS) in response to an urgent need for seawater inorganic carbon measurements for the US GEOTRACES Zonal North Atlantic Survey Section. An initial cruise was aborted in late 2010 because of serious mechanical failure in the research vessel; the remainder of the North Atlantic study has been rescheduled for completion with a resumption of the cruise in October 2011. In collaboration with other GEOTRACES colleagues at the University of Miami, the effort of the BIOS team will be focused on collecting samples for dissolved inorganic carbon (DIC) and total alkalinity (TA), laboratory analyses of these samples, and subsequent entrainment/merging of these datasets into the U.S. GEOTRACES Zonal North Atlantic Survey Section core hydrography/bottle dataset for distribution to the project investigators and the broader scientific community. In total, 600 samples will be collected for this cruise with 300 samples being analyzed at BIOS and 300 samples analyzed at RSMAS. Approximately 200 samples were collected on the aborted 2010 cruise, and once returned to respective labs will be analyzed for DIC and TA. Additional samples will be collected on the resumed 2011 GEOTRACES cruises with samples analyzed in respective labs, and the entire dataset undergoing standard QC/QA protocols. Broader Impacts. It is widely agreed that the ocean biogeochemical research community needs a global view of the key and ancillary GEOTRACES properties. The major impact of this project will be its contribution to the U.S. GEOTRACES Zonal North Atlantic Survey Section through measurements of inorganic carbon. This contributes broadly to improved understanding of the inorganic carbon cycle in the North Atlantic Ocean. Although no graduate student is supported, this award will support improved skills of two research technicians, and data will be incorporated into a teaching module about the ocean carbon cycle for the Nippon Foundation-POGO centre of excellence at BIOS.
