Not this year but in 2016 there was very very industrial longline stretching for who knows how long around Manuk. I removed what I could with my dive guide for the entire last dive...pretty disheartening to realise I'd only removed a drop in the ocean so to speak. Will see if I can rustle up the photo...this was no local Fishermans line, it had been spooled out from a mothership
Another diver who had done Manuk before said "it wasn't the same Manuk".
I had not dived Manuk before so I have no personal comparison but have no reason to doubt the other divers comments as they had done Banda Sea several times prior.
