The great ocean conveyor is drawn

node

Wallace Broecker's article "The Biggest Chill" in Natural History, discussing the Younger Dryas cold reversal, carried a cartoon of the global thermohaline circulation as a single looping belt of warm surface flow and cold deep return. Drawn to explain abrupt climate change to a lay readership, it became the canonical image of the circulation in textbooks and news graphics — and fixed in the public mind a picture of one belt with one engine that the subsequent observational record does not support.

A node is not a place. Drawing it on a map would assert something about the world that no stored fact supports.

  22. The article in which the "great ocean conveyor" diagram of global thermohaline circulation first appeared, drawn as a cartoon for a lay readership in a discussion of the Younger Dryas. Citation details taken from a Journal of Physical Oceanography review of the conveyor concept read via search summary; the original article was not consulted.
