Seasonal-to-Interannual Modulation of Fine-Scale Thermohaline Structure

The overarching goal of this project was sustained sampling of upper ocean hydrography to resolve the seasonal-to-interannual modulation of meso- and fine-scale thermohaline structure. To achieve this goal, Spray underwater gliders made repeated occupations of a 1300-km meridional section northward from Hawaii to 34.5N along 158W. The data set includes 1014 glider-days, covering 22566 km over ground, 22720 km through water, with 4641 dives.本项目的核心目标为对上层海洋水文特征开展持续采样，以解析中尺度与细尺度温盐结构的季节至年际尺度调制规律。为达成该目标，Spray水下滑翔机（Spray underwater gliders）沿158°W经线，对从夏威夷向北至34.5°N的1300公里经向断面开展了多次重复巡航观测。本数据集涵盖1014个滑翔机作业日，累计地面航程22566千米、水体航程22720千米，完成下潜4641次。
