Bathymetric change analysis of Ramsey Bay, Isle of Man

The project analyses long-term seabed change in Ramsey Bay, Isle of Man, between 1881 and 1990 using GIS-based interpolation of historical bathymetric surveys, DEM differencing, and transect analysis. The results reveal spatially structured patterns of erosion and deposition concentrated within offshore sandbanks, indicating sediment redistribution and sandbank migration rather than uniform seabed change. Overall, the findings suggest that Ramsey Bay operates near dynamic equilibrium, with strong tidal forcing driving continuous internal reworking of sediment over centennial timescales.
