Undersea Lakes? Exotic Lakes? Lakes Inside Lakes?

Microbes discovered in extreme conditions on the sea floor could lead hope for the discovery of life on Mars scientists say. Always nice to see the boundaries of where life can exist expand, but what fascinates me is that the organisms were discovered near a lake of liquid carbon dioxide under the oceans’s floor. Lakes and ponds of exotic fluids on the ocean bottom are just something I never think of when I think of the seas. Though this one is covered with a layer of sediment, it gives hope that in deeper water CO2 lakes might be discovered.

In fact pumping CO2 into the deep ocean where it will persist as large undersea lakes has been seriously proposed as a solution for global warming. Personally I think it makes more sense to stop doing the things that are causing global warming rather than try to counteract it with even more experimental geo-engineering. History has not been kind to people who thought that further ecological meddling would fix earlier meddling. Like in the Simpson’s where they introduce snakes to eat the bird eating lizards. Then they introduce a special snake eating gorilla to eat the snakes. It goes downhill from there.

Moving right along, there is another type of exotic lake on the ocean bottom. At least one undersea brine lake has been discovered. Imagine, a lake under the sea, complete with shoreline, beaches, and waves. Makes me wonder if there are any other exotic pools of liquid under the sea. Maybe pools of molasses after the great molasses flood? And as for exotic lakes elsewhere, I already covered the methane and ethane lakes on Titan. And there appears to be a lake of liquid suphur on Jupiter’s Moon Io.

I have a fascination with things within things. In a similar vein Manitoulin Island, Canada, is the largest island lake on the planet, located in Lake Huron, one of the five Great Lakes. On Manitoulin Island sits Manitou Lake, the largest lake on an island in the world. And Manitou lake has islands of its own, some of whom have a few small ponds. Possibly the only ponds on islands in a lake on an island in a lake anywhere. I think that’s amazing, doesn’t everyone? OK, I need to get out more.

  1. Doug, always enjoy your blog–you bring up things that fascinate me–

    About 6 months back I read a book call Rare Earth (named after a hypothesis that states that the earth may a more unique planet than people like Sagan alluded that it was) and the author brought out that in these fissures and extreme conditions you bring up there are actually living organisms. In other words, they are finding organisms that can survive in temperatures far above boiling point and also below freezing. They refer to them as extremophiles (I think the spelling is correct). Anyhow, given your interests and from what I’ve read on your blog you would find the book interesting. A used copy can be purchased reasonably at Amazon.

    Regards,

  2. […] My post on lakes within lakes made me think about the other bodies of water or suspected bodies of water in the Solar System. Earth seems to have the only open bodies of water around, but there are a few other planets and moons that may have watery oceans of one sort of another. […]
