Ocean & Maritime
Whether it concerns research into tides, fish farming, wave impact, coastal erosion, sediment transport or salinisation, one thing is certain: the measurement solutions must be able to withstand the harshest weather conditions and unrelenting seawater. The option to measure autonomously and for a considerable long-term is also a key factor.
Applications on the coast or rather in the deep sea? No problem at all! And this applies to water quality, flow and current measurements as well as wave measurements up to fully equipped measuring buoys. In addition, measurements can be monitored in real time, allowing timely action to be taken when critical threshold values are about to be exceeded.
Possible measurements on seawater
Water quality measurement
If parameters such as the concentration of iron ions, nitrates, nitrites, ammonia, phosphates and total nitrogen and phosphorus have to be measured in salt water, analysers offer a solution. Both portable field devices and stationary devices for targeted research are possible here. Such an analyser may be regarded as an autonomous mini-lab because these devices automatically add chemical reagents to water samples that they may or may not take themselves. Next, the concentration of various nutrients is determined by means of photometry or colorimetry in combination with fluorescence. Using this method, nutrients can be measured very accurately even at low concentrations.
Flow and current measurement
The most suitable method for mapping ocean currents is via the acoustic Doppler principle as this method is robust, requires no calibration and is virtually insensitive to biofouling. It is also possible to perform either point measurements (flow meters) or current profiles (profile meters). Depending on the device, 2D horizontal or 3D vertical current velocity profiles can be measured.
For each type of project we work out the most optimal solution taking account of your wishes and budget. We support you from single sensor installations to advanced autonomous measuring buoys fully equipped with solar panels and weather stations to mobile measuring vessels such as AUVs (Autonomous Underwater Vehicles) and ASVs (Autonomous Surface Vessels). The latter can be controlled remotely or follow a pre-programmed route and take measurements in the water column and on the water surface respectively.
