Acoustic Doppler Current Profiler (ADCP) is a hydroacoustic current meter similar to a sonar, used to measure water current velocities over a depth range using the Doppler effect of sound waves scattered back from particles within the water column. The device used in the air for wind speed profiling using sound is known as SODAR and works with the same underlying principles.

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.
Digital sampling techniques ensure high accuracy, and the unique construction gives sensor stability at any depth. Temperature is always measured with a fast response PRT (Platinum Resistance Thermometer), and instruments also use industry standard strain gauge or resonant quartz pressure sensors.

This is a lightweight alternative to larger flow meters, ideal for use in applications where the superior durability and depth rating of larger meters is not necessary. Utilising the standard 125mm diameter impeller, this Model features speed and direction parameters as standard, with further options of temperature and depth.

NeerTide is Nano, compact, handy and versatile easy to operate and simple to install radar-based tide gauge recorder for hassle free and accurate monitoring and recording of the tidal data. NeerTide is made up of components designed to withstand the marine environment and housed in ruggedized water proof case making it extremely portable.
NeerTide does not have any submerged sensors or moving parts in water thereby reducing the maintenance required. It can be used for permanent installation for port operations or can be used as a portable tide recorder for short term use.

Sound Velocity Sensors and Profilers from Valeport, the world leaders in Sound Velocity technology – a position achieved by both innovative development and meticulous attention to detail throughout the design, manufacture and especially calibration processes. Having been established at the forefront of this field nearly a decade ago with Digital Time of Flight technology, Valeport have now made a series of incremental changes to reinforce that position, ensuring that Valeport SV sensors offer levels of performance that are demonstrably far in excess of even the latest offerings from our competitors.

A tide gauge is a piece of equipment used for measuring the changes in sea level with respect to a height reference surface. Although tide gauges have not been used as a primary source of sea-level data for several years, they play a key role in the instrumentation at modern-day tide gauge locations to verify water level.

A water sampler is often used in conjunction with a CTD. The water sampler collects 1 or more actual samples of water for analysis in the lab after recovery of the package. The water samples can be used to verify the accuracy of data measured by the instruments on the package, and/or to provide additional information that cannot be measured with an instrument in the field.

Weather Station (Airmar 110WX) accurately measures wind speed and direction, air temperature, barometric pressure and humidity in a compact platform with no moving parts and IPX6 waterproof rating.
