Glider Observations in the Kuroshio and South China Sea

The overarching goal of these Spray underwater glider missions was to observe internal waves in the Kuroshio and South China Sea near the Luzon Strait.

Internal Waves

APR 2007 - AUG 2011

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
