As my flight descends, I peer out at an alien landscape below. A volcanic island juts out of the Atlantic Ocean, with its cliffs rising at steep angles from the surrounding blue water. From above, the island looks like a rugged one, mostly reddish-brown rock with a few sandy beaches dotting the coast. To the northwest, I see another island, but its view is partially obscured by a sandy haze: dust from the vast Sahara Desert, 350 miles to the east.
The wheels of the plane touch down with a squealing chirp, and I arrive at my destination for the next three and a half months: Cape Verde, Africa. The terrestrial landscape I observed through my plane’s window, however, is not what brought me to this remote archipelago; rather, it’s the abundance of blue marlin.
