With the help of these two bathymetric maps, I know where to place the 18-20 m isobath (see black contours) Consequently, as of october 2014, I can - rule out the "need" to increase the effective wavelength of the Green wideband
- this is only acceptable if we accept to decrease dramatically the effective wavelength for the Red wideband
- this yields depths which are 1.4 times deeper
- if it can be confirmed, it should prove to be a generic finding for widebands
- if it can be confirmed, it warrants thorough investigation using HYDROLIGHT
- be less conservative when setting thresholds
