They haven't recovered definitive evidence of habitation on the shore of the freshwater lake that existed in the Black Sea basin before the inundation broke through the Bosporus. Bob Ballard brought up some material that was fashioned by humans, but it was modern contamination (i.e. something that sunk to the point where it was found). However, the show that I say (National Geographic Explorer) indicated that the soil provided evidence of human habitation at the time of the inundation, but I haven't heard anything about that from any other source.
Today Ballard, famous for finding Titanic, confirmed that his research team, sponsored in part by the National Geographic Society, has identified a wooden structure on a gently sloping shelf near the convergence of two submerged ancient river beds [under the Black Sea].
“This is an incredible find,” Ballard said in a telephone call to the National Geographic Society from the expedition ship Northern Horizon. “It consists of [the remains of] a single building with a hewn beam and wooden branches that formed the walls and roof of a structure—most likely a house. We have also found and photographed stone tools, possibly a chisel or an axe, and ceramic storage vessels, all untouched since the flooding of the Black Sea.”
The find represents “the first concrete evidence for the occupation of the Black Sea coast prior to its flooding,” says expedition archaeologist Fredrik Hiebert, of the University of Pennsylvania Museum of Archaeology and Anthropology. “This is a major discovery that will rewrite the history of civilizations in this key area between Europe, Asia, and the Middle East.”
"...During the 1999 expedition, Ballard’s team discovered a submerged ancient shoreline with a flat beach area beneath about 550 feet(168 meters) of water—evidence supporting Ryan and Pittman’s theory."
