Christmas Island Buoy

This was a nice compact small fetch area swell off NZ. Direction was 210-20. It came in 2.5 ft 17 seconds or so, with north winds just south of us on the central coast, and moderate local NW prevailing winds.

Buoy raw energy is taken from the buoy web sites in m*m/Hz. These values are plotted as a function of wave period instead of wave Hz because wave period is proportional to wave velocity, and wave period squared is proportional to wave energy. There are 3 fixed scales at 5,10, and 15 m*m/Hz. The fourth scale is rhino, and it self-adjusts depending on the largest swell energy entry. Let me know if you have any feedback/ideas All copyright on plots reserved - email me if you want to use these plots or their source in perl. The programs also require ghostscript,lynx, and date. So think UNIX/linux/*BSD.
