The map is adorned with sketches including drawings of ships, sea monsters, compass roses surmounted by fleur-de-lis, and loxodromes in red, yellow and black.
The decorative aspects of the Bonaparte map including the coloured loxodromes, the use of gold, drawings of sea monsters and other artistic embellishments belong to a style perfected by professional mapmakers and artists in Amsterdam in the sixteenth and seventeenth centuries.
The conclusion from previous studies in Siberia and Canada was that Arctic shorebirds (and perhaps also terns and jaegers) fly along great circle routes (orthodromes), rather than along constant geographic compass courses (loxodromes or rhumb lines) (Alerstam and Gudmundsson, 1999b; Alerstam et al., 2001).
Radar studies could also help us to investigate whether the birds' migration routes conform to great circles (orthodromes), which are significantly shorter than rhumb lines (loxodromes) at polar latitudes, and to evaluate the observed flight routes in relation to the orientation difficulties encountered in this area because of extreme geomagnetic field conditions close to the North Magnetic Pole.
This has the consequence that magnetic loxodromes (tracks with constant magnetic compass courses) curve unfavourably (prolonging flight distances) in the Taymyr sector, while they curve in a distance-saving way (compared to geographic loxodromes, i.e., tracks with constant geographic courses) on either side of this region.
A ship will follow a loxodrome, or rhumb line, by maintaining a constant compass reading that can only be plotted on a Mercator chart with accuracy.
