Navis BGC Autonomous Profiling Float

Sea-Bird Electronics

The SBE 41CP CTD measures conductivity, temperature, and pressure (depth). The pump-controlled, T-C ducted flow minimizes salinity spiking caused by mismatch of temperature and conductivity measurements.

The individually calibrated SBE 63 Optical Dissolved Oxygen sensor is integrated within the CTD flow path, providing optimum correlation with CTD measurements.

The ECO Triplet is three sensors in one, providing any combination of fluorescence (chlorophyll, CDOM, phycoerythrin, phycocyanin, rhodamine, or uranine) and backscattering (blue, green, or red) measurements. The Triplet is clamped to the float hull, and cabled to the end cap.

The carefully engineered anti-foul protection includes anti-foulant devices, a U-shaped flow path, and an integral pump. On the float’s ascent, as it approaches 10 to 5 dbars beneath the ocean surface, the pump turns off. The U-shaped flow path prevents sea surface oils and contaminants from being ingested while proceeding through the ocean surface skin and sitting at the surface during data transmittal. Between profiles the pump is off. The U-shaped flow path prevents water flow through the system caused by waves or currents; minute amounts of anti-foulant concentrate inside the conductivity cell to minimize bio-fouling.
