Ocean Scan Geo-Solutions Ltd specialises micro-bathymetric surveys which rely on the principles of acoustic imaging and measurement. These surveys utilize multibeam scanners to measure millions of discrete data points which are processed to produce a 3D surface. The surface is fully rotational, geo-referenced, scaled and distances and dimensions can be measured from these scans.
Ocean Scan Geo-Solutions Ltd has the capability to perform both hydrographic mapping (for the use and production of maritime navigation charts/ aids) and bathymetric surveys (for engineering, dredging and environmental work). The company can perform these surveys using single beam and multi-beam echosounders with both RTK and DGPS positioning. These surveys are performed to IHO S-44 standards, USACE standards or project specific standards.
Ocean Scan Geo-Solutions Ltd tidal measurements: For the establishment of datums and benchmark height information for land and hydrographic surveying applications Environmental applications To provide Mean Sea Level information and tidal constituents. Production of tidal calendars and tide tables from predictions which are produced in house
Ocean Scan Geo-Solutions performs sediment sampling using grab samplers and sediment cores and collects water at various depths using Niskin samplers or a rosette. Excellent relationships are maintained with environmental laboratories in Trinidad and Tobago who can readily perform chemical and biological analyses of samples
Ocean Scan Geo-Solutions Ltd can deploy monitors and sensors to measure physical air quality by analyzing gas concentrations to PPM and PPB levels of O2, SO2,CO, CO2 and O3. Noise and dust can also be measured using portable instruments and sensors
Ocean Scan Geo-Solutions Ltd conducts water quality surveys using moored or profiling instruments to measure sea temperature, salinity, conductivity, pressure, dissolved oxygen, turbidity, pH, and chlorophyll.
Ocean Scan Geo-Solutions Ltd provides surface and subsurface positioning using acoustic and GNSS technologies subsea and surface equipment, points/features of interest can be accurately positioned. Rigorous QA/QC statistical software is also used to ensure that the positions are accurate. The company has access to Satellite based Differential Global Positioning System (DGPS) corrections and land based reference stations for DGPS and Real Time Kinematic Global Positioning Systems.
