Aquatica Marine provides a quality oceanographic and hydrology survey services to the civil, construction and renewable energy markets. As the focus on environmental impact increases, our customers are required to measure and model the impact of their development schemes in the context of riverine, estuarine and coastal environments, including tidal dynamics, turbidity monitoring and pollutant discharges.

Aquatica Marine boasts an in-house team of oceanographers, geoscientists and mathematical modellers to ensure we have developed a strong understanding of survey strategy, design and implementation with an inherent respect for health, safety and the environment.

Our specifically designed MCA coded survey vessel S.V.”Investigator” is capable of providing oceanographic services over short or long periods, including for both vessel mounted and seabed deployed systems and sensors.

We aim to simplify the process of obtaining and managing critical data throughout the life-cycle of our customers’ engineering projects. The planning, management and performance of projects has served to demonstrate that quality of service is inextricably linked to measures taken to safeguard the integrity of and maximise the value of data. The provision of quality geo-referenced / GIS data allows for analysis and interpretation of oceanographic parameters including current, wave and meteorological data.

Large engineering projects often require the delivery of Oceanographic data in real time to provide information for operational planning. Telemetry data transfer from measurement and sampling sensors allows Aquatica Marine to provide a real-time monitoring service – a complete solution for understanding complex inter-related oceanographic dynamics. This capability provides the opportunity to measure and model surface, water column and bed parameters and subsequently analyse the multidisciplinary data with our established Trimble 4D Control software systems.

Applications

  • AWAC deployment
  • Vessel and seabed installed ADCP survey
  • Water turbulence study
  • Dilution and circulations analysis
  • Wave Measurement – surface or seabed sensors
  • CTD – discharge and current profile survey
  • Tidal, water level and surge gauging
  • Turbidity measurement
  • Mathematical and Statistical Analysis and Reporting

Drogue and Dye Tracing

Dye tracers are used to track the flow of water, whether natural flow modelling or tracing discharge and pollution, it is possible to achieve both qualitative and quantitative analysis.

Wave Monitors

Utilises Linear Wave Theory wave analysis techniques for shallow water deployment, can also record the tide and will operate autonomously.

Turbidity Meter

Measures the turbidity of water to industry standard units by using optical scatter detection techniques. Qualitative measurements are recorded.

CTD

Measures a depth profile of conductivity, temperature and pressure to provide accurate information on the speed of sound in water, also provides data on salinity and water density.

Acoustic Doppler Current Profiler

Similar to a sonar, the ADCP is used to measure the velocity of water currents over a depth range by using the doppler effect of sound waves, scattered back from particles within the water column.
