SATELLITE-ENABLED TEMPORAL WATER LINE MAPPING: A NOVEL METHOD FOR MONITORING LARGE-SCALE INTERTIDAL DYNAMICS

Speaker: Clive Neil, National Oceanographic Centre, United KingdomThe NOC have been at the forefront of research and development of novel environmental mapping capabilities using marine radars for well over two decades. The high-resolution X-band radar Temporal Water Line mapping (TWL) method, developed at NOC (Bell, 2015), is now provided as a commercial service by Marlan Maritime Technologies Ltd. Ongoing development work at NOC has adapted the TWL method to use a combination of SAR and Optical imagery from the ESA Sentinel satellites to estimate intertidal bathymetry over large spatial extents. This per-pixel method provides a unique capability for ongoing monitoring of large spatial extents at decimetre scale accuracies.
