Hawaii

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.

Project Dataset Processing

  • Averaged to 10-m vertical bins
  • Bins improve ease of use
  • Bins allow for easy integration of ADCP acoustic backscatter and velocity data
  • Filtered using QC flags
  • Only high-quality data are represented in each bin
