BAD EXCUSES FOR MISSING WORK

ODD LIFE IN GREAT LAKES

Scientists have found some odd life forms in Lake Huron.

Peculiar geological formations are supporting floating plumes and purple mats of microbes dwelling in enclaves of the Great Lakes –where researchers have found sinkholes made by water dissolving parts of an ancient underlying seabed.

The scientists report that some deep sinkholes act as catch basins for dead and decaying plant and animal matter and collect a soft black sludge of sediment topped by a bacterial film.

These environments are also similar to those around deep-sea hydrothermal vents and cold seeps, where many odd forms of life have also been found.

Groundwater beneath Lake Huron is dissolving minerals when from the defunct seabed and carrying them into the like to form these exotic, extreme environments, said Bopaiah A. Biddanda of Grand Valley State University, in Muskegon, MI. Biddanda is one of the leaders of the study of these odd environments.
