Ocean and coastal.

Technologies

• CTD profilers Conductivity, temperature and depth instruments for salinity and density profiles.
• Acoustic Doppler current profilers (ocean) Moored and hull-mounted profilers for currents through the water column.
• Moored and drifting buoys Surface meteorology, waves and sea temperature from moorings and drifters.
• Argo-class profiling floats Autonomous floats that profile temperature, salinity and biogeochemistry to depth on a regular cycle.
• Tide gauges and sea level Long-term sea level and storm surge records tied to geodetic benchmarks.
• Gliders and uncrewed surface vehicles Mobile autonomous platforms that sample along tracks for weeks.
• Hydrophones and ocean acoustics Passive acoustic monitoring for marine life, vessels and seismic events.
