Dear Ben,
Could you please tell me where the South Pacific
  is? I'm referring to the April issue's travel article
  about Chuuk, which mentions that these islands are
  in the "South Pacific."I've been there twice, and each
  time the islands were above the equator. I'd suggest
  that this places them in the Central Pacific, or even
  the "North" Pacific, if the South ends at the equator.
However, while I hear plenty of South Pacific I
  almost never hear North Pacific. Seems like most
  writers instinctively add "South" when they are writing
  about almost anywhere in the Pacific Ocean. So,
  as you're an editor, please tell me where the South
  Pacific starts and ends? Or better, edit out "South" for
  islands above the equator. Maybe get James Michener to write another book titled Tales of the North Pacific to
  even out the misuse.

Dear Harry,
You're right. Mea culpa. I suppose we Americans
  perceive any islands south of Hawaii with palm trees
  as the South Pacific, and of course we are wrong.
  But in our defense, and in Chuuk's defense, James
  Michener's Tales of the South Pacific is a collection of
  stories based on his experiences in the Pacific theater
  during World War II, in which Chuuk played a big
  role. So because Michener created the palm-treed
  "South Pacific" identity that seems to encompass
  Micronesia, we'll blame him for now, and think twice
  before using that phrase for north-of-the-equator
  locations in the future.
