Measuring the AMOC and meridional ocean heat transport at 26.5N: Extension of the RAPID-MOCHA Array

该项目将继续美国对大西洋26.5北纬的RAPID-MOCHA海洋系泊阵列的贡献，再持续18个月，使数据记录的长度达到17.5年。该时间序列监测了大西洋经向翻转环流（AMOC）和大西洋经向热输送。RAPID-MOCHA阵列所产生的结果改变了人们对深海环流和海洋盆地热量运动的广泛看法。对海洋结构和洋流的持续监测将使海洋学家能够更好地确定控制热输送的相关动力学，并改进海洋在气候模式中的作用。众所周知，AMOC是气候系统的重要组成部分，人们相信，更好地了解控制AMOC热输送的海洋动力学将有助于更好地从根本上了解地球。美国气候系统和改进的气候预测。RAPID-MOCHA的18个月延期将允许对系泊阵列配置进行长期规划和重新考虑。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The project will continue the US contribution to the RAPID-MOCHA oceanographic mooring array at 26.5N in the Atlantic Ocean for an additional 18 months, bringing the length of data record to 17.5 years. This time series monitors the Atlantic meridional overturning circulation (AMOC) and meridional heat transport in the Atlantic Ocean. The RAPID-MOCHA array has yielded results that have changed widely held views about the deep ocean circulation and movement of heat across the ocean basin. Continued monitoring of the ocean structure and currents will allow oceanographers to better determine the relevant dynamics that control heat transport and to improve representations of the ocean role in climate models.The AMOC is known to be an important component of the climate system and it is believed that better understanding of the ocean dynamics that control heat transport in the AMOC will lead to better fundamental understanding of the Earth?s climate system and improved climate prediction. The 18-month extension of the RAPID-MOCHA will allow for longer term planning and reconsideration of the mooring array configurations.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
