The CUGN includes gliders on four of the traditional cross-shore CalCOFI lines, Line 56.7 off Bodega Bay, Line 66.7 off Monterey Bay, line 80 off Point Conception, and line 90 off Dana Point, and on an alongshore line at CalCOFI station 60 that connects lines 80 and 90.
California Underwater Glider Network
Sustained baseline observations of climate variability off the coast of California
Autonomous underwater ocean gliders are deployed in a network to provide real-time data. Spray gliders repeatedly dive from the surface to 500-m and back along a path. Each of these dives is about 3-km long and takes about 3-hours. A full glider mission typically lasts about 100 days, covers over 2000-km and provides four to six full transects.
Applications for CUGN glider data include ocean heat waves, algal blooms, storms, fisheries impacts, marine operations, oil spill response, and weather forecasts.

Choose the best data product to meet your needs
Designed to meet user needs, these are our most commonly used data products. After each glider mission, data are post-processed and added to the Project Dataset.
Expanding upon the CUGN Project Datasets these products provide insights into how our coastal water are changing over time.
Science Quality Binned Project Data
Cleaned, post-processed and vertically binned to meet user needs
Project Dataset Processing
After each glider mission the data are post-processed and added to the Project Dataset file.
- Data are averaged to 10-m vertical bins
- Vertical binning improves ease of use
- The 10-m bins allows for easy integration of ADCP acoustic backscatter and velocity data
- Data are filtered using QC flags
- Only high quality data are represented in each bin
Data are available in NetCDF files and are also available via our ERDDAP server which offers additional file types, data subsetting, visualization options and more.
