Repeat Observations by Gliders in the Equatorial Region

Spray underwater glider operations were conducted during 2013-2016 west of the Galapagos Islands.

OCT 2013 - OCT 2016

Temperature, Salinity, Doppler Velocity, Acoustic Backscatter, Depth-Averaged Velocity

  • Region: Galapagos
  • PIs: Daniel L. Rudnick, W. Brechner Owens, Kristopher B. Karnauskas and T. M. Shaun Johnston
  • Funded by: National Science Foundation; Global Ocean Monitoring and Observing (GOMO) Program - NOAA

Project Dataset Files

Cleaned, post-processed and vertically binned to meet user needs

Access Options

Data are available in CF compliant NetCDF files and are also available via our ERDDAP server which offers additional file types, data subsetting, visualization options and more.


OCT 2013 - OCT 2016

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
