Why Does the South Street Seaport Smell?

Unfortunately, there are no clear answers, but a number of hypotheses were posed to the NY Post. They include rotting fish (ghosts of the Fulton Fish Market?), bodies from the Bodies Exhibit, illegal dumping, the NYC Waterfalls--and the smells reek like "dead rat," "stinky cheese" and "raw sewage." Mmm, and naturally that hurts some restaurants in the neighborhood. A smell scientist put his olfactory nerves to the test and told the Post, "Yes that is fish. But it's also yeasty, like bread." Like Subway's bread?
