Most of the information in the Svalbard chapters will apply to Jan Mayen as both are high Arctic environments. We have added the following specifics for Jan Mayen.
The volcanic island of Jan Mayen lies at about the same latitude as Nordkapp in Norway, but its position, 290 nm northwest of Iceland and 250 nm east of Greenland, is as isolated as it sounds—a destination for the serious seeker of out-of-the-way places. A passage there is in league with those to Greenland and Antarctica. Only very experienced sailors with a sturdy offshore boat should attempt to go there.
Jan Mayen is 53-kms long and barren. It is dominated by Beerenberg (alt 2277 m), an impressive glaciated volcanic cone which is one of the largest in the world. It last erupted in 1985.
