Oh dear.... you evidently don't realise DigitalGlobe, which owns Tomnod, retasked two of its 5 satellites to photograph the area on Sunday.
To be honest I didn't click on the link, Tomnod is a silly name and sounded like someone's personal website !
I'd still wonder about whether any useful information will come of it... people with no SAR experience will simply be tagging general rubbish that can be found floating around the worlds waters..... all Tomnod will likely end up with is a database of false positives.
In all honesty, I think its more of a
PR marketing exercise for DigitalGlobe than anything useful.
