Wierd sounds on sonar

[codmander]

sounds like a sinking ship ((sort of)) sank a small coastal vessal yesterday could it be that? or a mine or --something i dont know about --yet
certainly dosn't sound like props :hmm: and i dont think that ship was close to this area

Dolphins maybe? They sound totally "alien" on the hydrophone.
