The logo was made based on the recommendations of R Packages (2e). The wave in the background is part of "The Great Wave off Kanagawa" (神奈川沖浪裏) by Katsushika Hokusai (1831), based on the Ukiyo-e technique of woodblock printing. It’s a lovely connection between my love for woodworking and my fascination with the ocean. It is also a reference to the fact that marmap was originaly designed to help with oceanographic cruise preparation, and I have used it both on land and at sea. Check out DAUNPAPUA, an oceanographic cruise on the exploration of deep-sea biodivesrity in Papua New Guinea, which was prepared using marmap.
