R.R.S Cape

You wake up confused inside the R.R.S Cape, a research submersible on an expedition to survey a newly discovered archipelago. As you come to your senses, you realise that you are stranded *somewhere* at the bottom of the sea & oxygen is quickly running out... With limited air, a map & any clues you can gather from inside your soon-to-become coffin, can you deduce your precise location to call for a rescue mission before it is too late?
