A fantastic collection of new images of the northern lakes has just arrived: http://saturn.jpl.nasa.gov/photos/raw/rawi...?imageID=298704

I have given the hypothesis of marsbug some thought, and considering the possible chemistry of the lakes that could hold dissolved organics that indeed might bond into something of the kind.
An oily organic substance is also possible, it would also dampen waves, but would it be to heavy float? Lastly we have the foam proposed by the scientists involved in these studies, yes it would float, yet if there's any wind it would move. Regardless of those alternatives, I label the idea by marsbug a plausible alternative. |

yet if there's any wind it would move. On the evidence of the recent re-observation of the Ligeia example (post 59) they do move, very slowly and mainly shorewards. That one also spread out over a wider area and faded somewhat after some months. I find it hard to imagine either waves or wrinkles hanging around in the same location for that long. |

Waves seem to be a less likely alternative from what we know now. That fading out and spreading points to the other plausible alternative as I see this right now, and that would be a collection of clumps of some lightweight organics behaving like the collections of woodpieces, plastic bottles and styrofoam one can find floating together on the ocean nowadays. Those also move slowly toward the shore and are only sensitive to the wind to some degree, and only sometimes reach harbours and bays since currents easily can disperse them. What I had written the above I realised it is not anything else but a small variation on the foam idea with the pieces just being less sticky. But I let it stand. |
