The service integrates satellite imagery to investigate coastal and shallow-marine environments, including submerged cultural heritage. It produces satellite-derived bathymetry, benthic habitat classifications and water-quality indicators, while supporting time-series, seasonal and event-based analysis. Outputs guide survey planning, environmental monitoring and assessment of coastal, seabed and anthropogenic pressures.
Integrated remote sensing service for the investigation of coastal and shallow-marine environments, including submerged cultural heritage assets. Satellite imagery is analyzed before the field deployment to define survey priorities and environmental zones. Satellite-derived bathymetry estimates water depth from wavelength-dependent light attenuation using empirical, band-ratio, semi-analytical and/or machine-learning approaches. The method is applied where water clarity, seabed visibility, image quality, depth range and reference measurements are adequate. Corrected multispectral imagery can also distinguish broad benthic and seabed-cover classes, including seagrass, macroalgae, sand, rock, mixed substrate and anthropogenic impact, subject to satellite sensor resolution and field-reference quality. The same image processing workflow supports mapping of optically detectable water-quality indicators, including turbidity, suspended particulate matter, water clarity, chlorophyll-a, algal-bloom conditions, colored dissolved organic matter (CDOM) and water-colour indices, supporting temporal comparison. RTK-GNSS, SonarMite depth measurements, conductivity, temperature/pH measurements, and shallow-water resistivity provide targeted field control. Earth Observation processing, bathymetric modelling, habitat and water-quality classification and uncertainty assessment are undertaken as part of the same site-specific deployment.
