0117919 LukasThis project focuses on observing and understanding ocean-climate related processes in the North pacific subtropical gyre by conducting two additional year of hydrographic sampling at the Hawaiian Ocean Time-Series (HOT) to extend the record to 15 years. This work also support the biogeochemistry research component of HOT. The analysis of the time series will seek to improve our description of ocean climate variability by combining observation from HOT with numerical models to understand the causes of this variability. In particular, the subduction process at the subtropical front will be studied in relation to water mass variability observed at the HOT site, including surface layer variations due to air-sea interactions. This project will also contribute to the Climate Variability and Predictability (CLIVAR) Program.

0117919 Lukas该项目的重点是通过在夏威夷海洋时间序列（HOT）进行为期两年的水文取样，将记录延长至15年，观察和了解北太平洋副热带环流的海洋气候相关过程。这项工作也支持了HOT的地球化学研究部分。对时间序列的分析将设法改进我们对海洋气候变异性的描述，方法是将HOT的观测与数值模型相结合，以了解这种变异性的原因。特别是，将研究亚热带锋的俯冲过程与HOT站点观测到的水团变化的关系，包括由于海气相互作用引起的表层变化。该项目还将为气候多变性和可预测性方案作出贡献。
