For the metric people who don't know random US states: 335 meters thick and about the size of Palestine.
Palestine in particular is a country that is very difficult to judge the size of, for very political reasons. It's actually far easier for someone to look at a map of Delaware and judge its size than to look at a map of Palestine and judge its size.
≈ (0.2 to 0.3) × mass of a Handy size cargo ship ( 28000 to 40000 lg tn )
≈ (0.3 to 0.5) × mass of a Small Handy size cargo ship ( 20000 to 28000 lg tn )
≈ 0.83 × daily mass of trash produced in New York City (≈ 1.2×10^7 kg )
EDIT:
For the ice slab in question, W|A gives following comparisons:
≈ ( 0.25 ≈ 1/4 ) × total area of Wales (≈ 8023 mi^2 )
≈ 1.7 × total area of Rhode Island ( 1212 mi^2 )
≈ 3 × area of forest flattened by the asteroid explosion over Tunguska in 1908 (≈ 2000 km^2 )Maybe make it a greasemonkey script - then hook into Wolfram Alpha and display from that. GeoIP might not be too big on an issue, either...
Ultimately, it's not about whether the idea is original, but how the idea is executed. Think about it - how many social networks were there before Facebook? It isn't like Facebook is original, or the first, or even the last! Similar with Google (do you really think there won't be something that takes over Google's position with search, or does it better, or different?).
Don't worry about originality! Just take your idea(s) - and try to execute them - worry about what you can control, instead of what others control.
I will say that I'm live in the US and don't have any real sense of the size of Rhode Island, or Palestine for that matter.
They have their own brief blog post at: http://www.projectmidas.org/blog/larsen-c-ice-shelf-poised-t...
In this case, it tells us this shelf is slightly taller than the Eiffel Tower [0] with an area a bit smaller than Bali. [1]
