Watch/listen to a NOAA podcast on the Sea of Cortez 2010 expedition taking place in Ballena Bay just off the Isla Espíritu Santo. The project will begin with a sonar survey of the sea floor using both a side-scan sonar and a subbottom profiler, and will focus on the deeper-water portions in an attempt to identify features that can be tested for archaeological material. Through this endeavor scientists are hoping to identify and recover cultural material, identify and map the paleoshoreline and adjacent landscape, and collect intact terrestrial sediments and floral and/or faunal samples.
