Instrumentation

We maintain a basic inventory of instrumentation for measuring oceanographic parameters in-situ over long periods of time (4 to 12 months) and the platforms on which to deploy the instruments. Parameters include current speed and direction, temperature, salinity and turbidity. We maintain data loggers which can be easily customized to accommodate new sensors as the need arises.

Most frequently used instrumentation:

• Sea Bird Seacat 16 and 16plus to measure and internally log temperature, salinity, pressure and to log external sensors such as a transmissometer or optical backscatter sensor.
• Sea Bird Microcat 37SM to measure and internally log temperature and salinity.
• Vector Measuring Current Meter (VMCM)
• Sontek Hyrdra data logger and Acoustic Doppler Velocimeter (ADV) and Pulse-Coherent Acoustic Doppler Profiler (PCADP)
• Brancker data logger
• Aquatec ABS
• MAVS
• RDI Acoustic Doppler Current Profiler (ADCP), 1200, 600 & 300 kHz
• Sea Tech Transmissometer, 25 cm, 5 cm
• WetLabs C-Star Transmissometer
• Sea Bird SBE-4 Conductivity Cell
• Sea Bird Pump
• Paroscientific Digiquartz Pressure Sensors
• Edgetech Acoustic Releases, 8242 & CART

Instrumentation often added to our moorings and tripods by other groups:

• Anderson Sediment Trap
• Time Series Sediment Trap
• Simple Tube Trap
• Sediment Sampler

Platforms we maintain in our pool and use to deploy our instrumentation:

• Large Tripod
• Minipod
• Micropod
• Flow-bee
• Surface mooring
• Subsurface mooring
