Evaluation of Finestructure Mixing Parameterizations Based on LADCP Shear

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。该项目将有助于更好地了解和测量地球仪周围的海洋混合，这对于了解海洋在气候中的作用和改进海洋气候预测模型非常重要。 将把低空声学多普勒海流剖面仪（LADCP）和CTD数据与微结构观测进行比较，以测试和改进实施Gregg-Henyey参数化方法的方法。 PI是LADCP数据处理和加工方面的专家，并认为混合估计中差异很大的差异可能是由于数据使用方面的问题。 该项目的最终目标将是公开分发一个用于估计海洋混合的联合收割机精细和微观结构数据库;准确可靠地执行Gregg-Henyey参数化;和一套改进的LADCP处理软件，PI通过发展获取和处理LADCP数据的精确技术，为海洋学家提供了良好的社区服务记录。 这些数据在全球范围内使用，影响着海洋学研究的许多领域。 该项目有可能进一步影响海洋学和气候学界，因为它使人们有可能根据海上常规可用数据自信地估计海洋混合情况。 PI对注意事项和问题有着深入的了解，并且独特地准备在这个话题上取得变革性的进展。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The project will contribute to the effort to better understand and measure ocean mixing around the globe, which is important for understanding the ocean role in climate and improving ocean climate prediction models. Lowered Acoustic Doppler Current Profiler (LADCP) and CTD data will be compared with micro-structure observations to test and improve methods for implementing the Gregg-Henyey method of parameterization. The PI is an expert in the treatment and processing of LADCP data, and believes that widely varying discrepancies in mixing estimates may result from problems in how that data is used. The ultimate goals of the project will be the public distribution of a combine fine- and micro-structure database for estimating ocean mixing; an accurate and reliable implementation of the Gregg-Henyey parameterization; and an improved suite of LADCP processing software.The PI has a strong record of community service to oceanographers through the development of refined techniques for obtaining and processing LADCP data. These data are used globally and influence many areas of oceanographic research. The project has the potential to further impact the oceanographic and climate communities by making it possible to confidently estimate ocean mixing from routinely available data at sea. The PI has intimate knowledge of the caveats and issues and is uniquely poised to make transformative progress on the topic.
