How do they detect you when on the bottom?

I agree with Bogdanz. Its ASDIC that detects you. The seafloor is mostly flat, apart from rocky shore areas, reefs or deep ocean mountains which are not the case here. For ASDIC, a laying submarine is a clear obstacle of high density material (low wave absorbtion, high deflection). However, there seem to be a chance to lay in some kind of seaflor ditch or trench and thus make ASDIC detection very hard. In a book about Operation Paukenschlag I read about Hardegen's U-123 succesfully hidden this way once at the East coast of US.
