The IDL should nominally follow the meridian of longitude that is 180 degrees from the Greenwich

Prime Meridian ... roughly down the middle of the Pacific Ocean. But in defining the line, it was

zigged and zagged where necessary to avoid cutting across nations and politically contiguous

island groups.
