It would then transect, or cross through, the beach of that shoreline at several different points to give the team a better idea of the lay of the land. Interesting features would immediately be plotted and videotaped. On land near Sinop, a valley leads to the current shoreline of the Black Sea. According to Mindell, the theory is that people settled on the bluffs where the river met the sea. This theory is consistent with observations made by the land archaeologists that all human settlements in the Sinop peninsula were made on ridges, bluffs, and other high points.
Clam shells, for one.
Ancient hunters and gatherers living near fresh-water lakes might have left mounds of shells behind. And mussels and clams both inhabit coasts their remains would be good delineators of shorelines. The change of course and the calm sea both made for a good day. Both ROVs were successfully lowered to the bottom of the sea several times at different places and depths. The Geek taped several minutes of very clear underwater footage that the team will study carefully.
