This approximate location seems to align with some of the drift modeling, just based on eyeballing what has been posted. Thank you for any correlation info you may have. Pls feel free to email me direct as well as post. Fred Wood, fbwood@hotmail.com, cell 703-615-4910 Dear Igor & colleagues:

I do not have access to landsat 7 images. I would guess that any remote sensing group working for the state of california would have a free access to those. The USGS route, not only involves payment but also a LONG delay as far as I recall. Now, with regards to the other imagery: astronaut acquired photographs: http://nuit-blanche.blogspot.com/2007/02/finding-jim-gray-astronaut-acquired.html my efforts have not yielded anything, so if somebody has an inside track there, please go ahead. My feedback has been that since the power went off on ISS this week-end and they are only three, very little activity could be unplanned. With regards to Envisat (and the much coarser resolution), I do not have an inside track in that either and then there is the additional cloud issue: http://nuit-blanche.blogspot.com/2007/02/finding-jim-gray-why-radar-should-be.html yet I recall that Feb 12 yielded a less than 90 percent cloud cover. Once again, with multispectral data, we are really looking for high contrast detection, nothing like resolving the boat. Igor.

Some objects such as a demasted yacht would drift differently than seat cushions, styrofoam cups and the like. Ofcourse a satellite is not going to spot a styrofoam cup and any such object would not be susceptible of being linked to a particular source. Life preservers would float for a long time, seat cushions eventually would become water logged or might have been well lashed down. If the yacht is not visible and debris is not visible, I can not believe the 12,000 volunteers searching the images all missed things. Query as “objects”.

Hopefully you can get someone to go out there and look now. Keep up the amazing work...here's to hoping he's still on his boat eating canned goods. Wow. That is very impressive.
