Hydrographic Surveying with Multispectral Imaging

Has anyone used, or considered using, the P4 Multispectral for shoreline or shallow hydrographic surveys?

I have been reading into Multispectral and have seen references to the blue band (0.45-0.52 μm) being able to penetrate water, but haven’t found anyone practically applying this concept.

I frequently work with surveyors in coastal and wetland areas and this would be a game changer since ortho surveys in RGB have trouble processing images of/near water due to the light reflected off the surface.

Google is (understandably) saturated with agricultural applications when it comes to multispectral drone surveying and hope that someone in this community may have a lead on more information.
