Oceanographic instruments
Oceanographic instruments
The CTD is perhaps the most commonly used tool in an oceanographer's armoury, providing detailed profile and time series data on the measured parameters Conductivity, Temperature and Pressure, but more particularly the calculated values of Salinity, Density and Sound Velocity. Today's powerful data acquisition systems also allow the addition of multiple additional sensors measuring chemical, optical and other physical parameters, such as pH, Redox (ORP), turbidity, dissolved oxygen, PAR and chlorophyll (amongst others).

Sound Velocity Sensors
Sonar, multi-beams, single beams, underwater positioning systems - they all use acoustic signals, and all rely on accurate knowledge of the speed of sound for optimal performance.
Estimates can be made from measurement of other parameters (Conductivity, Temperature & Pressure), but the best method is just to measure the speed of sound directly.
Optical Instruments
Fluorometer
MicroFlu The MicroFlu is a series of low-cost minituarised submersible fluorometers for highprecision and selective chlorophyll fluoroscence measurements. The combination of a minituarised design with long-term stability makes it suitable for algae monitoring applications in oceans, rivers and lakes as well as for all applications in the field of w
Nutrients
ProPSThe ProPS is an UV Hyperspectral Process Photometer that combines precision UV transmission measurements with a mathematical spectral analysing software in order to provide single substance concentrations from natural or artificial mixed samples.
The teaching mode of the software enables the user to look for different UV absorbing substances
Radiometer
Ramses-ACC The RAMSES-ACC forms part of a family of hyperspectral UV radiance & irradiance sensors. The RAMSES-ACC sensors are stand-alone highly integrated hyperspectral radiometers for both the UV and/or VIS spectral range. Small size and very low power consumption makes it suitable for hand-held and autonomous applications.
Plankton Counter
The Laser Optical Plankton Counter (LOPC) is the next generation in plankton profiling. The LOPC's high speed processing and improved detection plane provides detection counts at higher resolutions and higher concentrations with lower coincidence. This also allows the LOPC to be integrated into tow bodies such as the Moving Vessel Profile.
