Trinidad Head Ocean Observing Node WireWalker

THOON was established and continues to be supported with funding from California's Ocean Protection Council and California Sea Grant (CA Prop 68). THOON is deployed seasonally (spring to fall) due west of Trinidad Head in about 75 m of water at Station TH02 along the Trinidad Head Line.

The profiling mooring is a wave-powered WireWalker equipped with an RBR sensor package to profile temperature, salinity, chlorophyll, and dissolved oxygen throughout the water column at high temporal resolution (roughly every 8 minutes) and to transmit the data in near-real-time to shore via cellular communications. To measure pH throughout the water column, an experimental ISFET-based pH sensor was integrated into the sensor package, building on recent progress towards configuring the sensor for rapid profiling applications.”
