Flexible platforms that expand sensor capabilities of profiling floats by providing multispectral radiometry, nitrate, scattering, beam attenuation, chlorophyll, and CDOM measurements to complement the temperature, salinity and oxygen measurements of the profiling float.
A Navis autonomous profiling float with integrated optical Dissolved Oxygen sensor (SBE 63) and bolt-on WET Labs ECO Triplet is now available from Sea-Bird Scientific. The sensors take continuous measurements at 1 Hz through ascent, and provide high accuracy, resolution, and stability.
The SeapHOx combines the Satlantic SeaFET pH sensor with the Sea-Bird Electronics SBE 37-SMP-ODO MicroCAT CTD+DO sensor. The SeapHOx allows for the integrated data collection of pH with the critical oceanographic and biological measurement of temperature, salinity, and oxygen. The integrated package also allows the SeaFETTM to take advantage of the SBE 37's pumped flow path and anti-fouling technology, extending deployment durations in some cases.
The standard SBE 9plus underwater unit has an aluminum housing rated to 6800 meters (22,300 ft), and is supplied with one conductivity and one temperature sensor (fitted with a TC Duct and constant-flow pump), and an internally mounted, temperature-compensated Paroscientific Digiquartz pressure sensor for 6800 meter (10,000 psia) full scale range.
SBE 11plus V2 Deck Unit includes RS-232 and IEEE-488 computer interfaces, a modem channel for real-time water sampler control (including water sampler control push buttons and status lights), NMEA 0183 interface for adding GPS position to CTD data, 12-bit A/D input channel for surface PAR sensor, switch-selectable 115/230 VAC operation, audio tape interface (data backup), LED readout for raw data, and audible bottom contact (or altimeter) alarm.
The SBE 37-IM MicroCAT is a high-accuracy conductivity and temperature sensor/recorder (pressure optional) with internal battery, non-volatile memory, and built-in Inductive Modem. Calibration coefficients are stored in EEPROM, allowing output of C, T, P, and time in ASCII engineering units (decimal or XML; raw output available).
The SBE 37-IMP MicroCAT is a high-accuracy conductivity and temperature (pressure optional) recorder with internal battery, non-volatile memory, built-in Inductive Modem, and Integral Pump. Calibration coefficients are stored in EEPROM, allowing output of C, T, P, and time in ASCII engineering units (decimal or XML; raw output available).
SBE-49 FastCAT CTDThe SBE 49 FastCAT is an integrated CTD sensor intended for use as a modular component in towed vehicles, ROVs, AUVs, or other autonomous platforms that can supply DC power and acquire serial data. FastCAT’s pump-controlled / TC-ducted flow feature minimizes salinity spiking, and its 16 Hz sampling provides very high spatial resolution of oceanographic structures and gradients.
The SBE 52-MP is a Conductivity, Temperature, Depth (pressure) sensor, designed for moored profiling applications in which measurements are made from from a device that travels vertically beneath a buoy, or from a buoyant package that is winched up and down from a bottom-mounted platform.
The SBE 53 BPR measures full ocean depth water level with extremely high resolution, accuracy, and stability. The BPR combines a uniquely precise and stable time base with low-power frequency-acquisition circuitry, Paroscientific Digiquartz® pressure transducer, non-volatile 32 MB FLASH memory, and a precision thermometer, to provide unprecedented bottom-pressure recording capability. An optional SBE 4M conductivity sensor can be added to provide salinity data.
