Sedimentology - remote sensing


While research has shown the possibility of seafloor mapping at depths of up to 30m, a number of factors restrict exploration of bathymetry such as pixel size, sun azimuth, season, water turbidity and suspended sediments, as well as seafloor topography13. Though the 30m composite images of Lesvos were able to penetrate shallow water to expose submerged features, pixel size prevented mapping of beachrock outcrops because they couldn’t be differentiated from other sediments or underwater features. Higher resolution aerial images enabled accurate beachrock mapping. These images were obtained by a helicopter but increasingly, remote drones are a cost effective way of collecting spectral and spatial data for further analysis. Spatial analysis of the mapped beachrock shows correlations between beach type and sediment availability (figure 9), as well as slope, and proximity to freshwater sources such as rivers mouths and tidal flats.
