During 2004–2010, we studied the sand dunes of Oman using trenches, optically stimulated luminescence age dating, and modern wind data. This work was undertaken for Petroleum Development Oman to define modern analogs for ancient dune reservoirs that produce oil and gas in the sultanate. An unintended consequence of our work was the recognition of a band of high wind energy along the east coast of Oman that might be suitable for commercial wind power extraction, especially during the peak wind season of the Indian monsoon. Our geological work indicates that this basic wind regime has been in place for at least 200,000 yr and is thus not a fluke of present-day climate.
