Here’s a question that everyone seems to want an answer to: how did freshwater organisms survive a salty flood? A recent article at Your Origins Matter, Flood Survivors – derived from an Acts & Facts article by John Morris from 2011 called Fish in the Flood – tries to offer some solutions. After first acknowledging that survival would have been very difficult, and that most didn’t make it, Morris produces his first idea:

In the complex of events and conditions that made up the Flood, certainly there were pockets of fresh water at any one time. Remember, it was raining in torrents, and we can expect that the rain water was fairly fresh. Many studies have shown that waters of various temperatures, chemistries, and sediment loads do not tend to mix; they tend to remain segregated in zones. It would be unlikely for any one area to retain such zones for very long during the tumult of the Flood, but on a worldwide scale, some such segregated zones would have existed at any given time.
