| Vancouver Thermal Structure / Wedges on Venus | ||
| This notebook, started by Dahlen in May 1990, is contained in an orange binder
and has both written notes from Dahlen as well as those of Charles A. Williams, who at the time
was a postdoc working at Princeton with Dahlen. In addition, due to the nature of the work
laid out in this notebook, there are myriad graphs detailing the supposed shapes and slopes of
decollements and wedges.
The notebook begins with Dahlen's own notes on the thermal structure of Vancouver, where he employs the heat equation in a moving medium to estimate how temperature varies with depth. However about halfway through the notebook it shifts gears to be more decollement and wedge centric, especially with respects to those on Venus. Helping Dahlen on this was of course Williams, mentioned above. This collection can be found at: Guyot Hall, Princeton, NJ, 08544. Back to Main Page |
