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.

本项目的根本目标是实现对上层海洋水文特征的持续采样，以解析中层及细尺度热盐结构的季节至年际调节。为实现此目标， Spray 水下滑翔机沿158W经线，从夏威夷向北至34.5N，反复穿越1300公里的经向剖面。该数据集包含1014个滑翔机日，覆盖地面22566公里，水下22720公里，并进行了4641次下潜。
