What was the ocean circulation like during the time of Pangaea? So Enderton and Marshall (2009) wrote an interesting paper on the ocean circulation of various aquaplanets covered with certain terrain: e.g. an aquaplanet with a small ridge of land that ranged from North Pole to South Pole, and studied the effects it had on the ocean circulation.

I'm curious: Has anyone ever applied this type of analysis to a Pangaea-like planet?
Here is an estimate from Beauchamp and Baud (2002), for parts of the ocean around Pangea, for the latter parts of it's existence (~300-250mya). It is based on various previous papers that looked at deposits of carbonates and phosphate deposits, and made a few assumptions, including a sufficient supply of silica and nutrient inputs, and environments suitable for particular biota, including particularly siliceous sponges:
