A history of Stommel diagrams

Tiffany Vance and Ronald Doel have traced the history of the Stommel diagram from physical oceanography into biology, in their 2010 paper Graphical Methods and Cold War Scientific Practice: The Stommel Diagram’s Intriguing Journey from the Physical to the Biological Environmental Sciences in Historical Studies in the Natural Sciences (DOI: 10.1525/hsns.2010.40.1.1.)

The paper provides an rich history of how the innovative oceanographer Henry Stommel created his diagrams to emphasize the cross-scale dynamics of the ocean (See figure below), and how his diagram was adapted by biological oceanographers. However, they miss how Stommel diagrrams moved into ecosystem ecology and sustainability science.

Below I present a series of Stommel diagrams.  The first three figures are reproduced in Vance and Doel’s paper, the later three are from sustainability science.

First, Stommel’s original figure, which was designed to show how oceanic processes varied across scales, and that sampling efforts had to be planned with a consideration of these.
