    • Glider - Trinidad Head Line: 2025 November - Ongoing

    Metadata Updated: February 26, 2026

    The Trinidad Head glider line aims to extend the time series of sustained glider-based measurements off the California that begun in 2014. Seaglider and SGX underwater gliders repeatedly occupy a single section that extends offshore from the continental slope to 40.05N, 129W. Gliders profile from the sea surface to 1000-m depth and back every 6 hours while traversing the line at a speed of roughly 20 km/day. The Trinidad Head line is sampled by a single glider, which is replaced as needed to maintain continuous occupation of the section.
