What would you smell on a desert island?

Bit difficult seeing I've never been on a desert island, but i have been on an abandoned beach? It also depend on the whereabouts of the island. An island in the Atlantic is going to be different to an island in the Pacific, but I'm assuming you mean the stereotypical movie type islands. So in that case, you would smell plenty of sea saly, tropical plants (they give off an awful scent when they are heap of them) and perhps exotic scents like coconuts or bananas? Reall, it's what you imagine a desert island would be, what is on that island, and what they smell like
