Eery creepy science of the body farm.

Popular Science article: We need more 'body farms' to figure out how corpses rot - cadaver decomposition.

"unfortunately, a lot of people do die in the ocean…homicide victims are dumped, but also you’re going to have…maritime disasters, planes that go down, boats that go down, tsunamis...we still don’t know much about it. But researchers are starting to fill in the gaps in our knowledge...Gail Anderson, a forensic entomologist at Simon Fraser University in Burnaby, British Columbia... Kimmerle and her team are planning to study how corpses decompose in the state’s uniquely moist conditions at a new facility in Florida... Researchers do know that tissue may linger in water that is cold or low in oxygen, but predicting how a body will break down is rarely straightforward...“It really, really varies,” Anderson says. “In some of my experiments we’ve had pig carcasses…last months and months with almost no change whatsoever, and in some cases they’ve been skeletonized in three days.”
Water’s inhabitants can also complicate matters. On land and even in fresh water,will devour a body. In the sea, you’re more likely to find other arthropods such as and sea lice—or, less often, fish or sharks, Anderson says...She has seen how oxygen-rich water can better host voracious scavengers. “In some areas…there were such thick levels of on them you couldn’t see the carcass,” Anderson says.
