Now let’s look at Arcgis: Compete shows roughly 33K unique visitors for October and the numbers from Alexa are not much different. If we do a rough calculation (3000 photos * 1440 minutes * 31 days) we will arrive at 133,920,000 photos for October. Here is what we know about Flickr: According to Compete, Flickr enjoyed almost 20 million unique visitors in October who uploaded more than 3000 images per minute. I know that this is not “apples to apples” comparison, but since we are comparing only the amount of user-generated content it will work. Since there is no such website in the GIS space, let’s take Flickr. To illustrate my point, let’s compare to another website with massive amounts of user-generated content. It is not that is impossible for ESRI to achieve such growth in one month, it’s that there just isn’t any (publicly accessible) evidence to suggest that the number is anywhere close. Ok, so ESRI confirmed that there were indeed 400 million maps created on in October, but I am still not convinced… 'Who doesn't want 500,000-year-old ice in their drink?' he joked. The air bubbles trapped in it are under so much pressure the ice fizzes when it melts.' 'To be honest it's the cleanest water you can get. The arch 'sounded like shotguns being fired off all the time, due to the ice cracking.'Īnd what to do with all of that ice? Perry and his fellow biologists have a unique use for icebergs: They put them in cocktails. They're constantly moving and cracking, he said. Icebergs are surprisingly noisy as well, according to Perry. 'It's not the first one I've seen, but it's the most artistic.'

So, with time, the waves carve through the face to the other side,' Scambos told. 'As the waves begin to pound out a dimple in the ice facewall, it focuses the wave energy, leading to more rapid erosion at the center. Sure, but how did this iceberg form in such a stunning fashion? Wave action, Scambos explained, and it's more common than you might think.

'It starts off as a rugged piece of ice that waves and sunshine then sculpt.' 'Complex, sculptured icebergs like this are usually formed from ice that broke off of fast-flowing glaciers,' Scambos told. Yet beautifully sculpted icebergs like the one Perry found are actually fairly common, thanks to the natural forces of the seas and the skies, explained Ted Scambos, lead scientist for the National Snow and Ice Data Center at the University of Colorado in Boulder. Icebergs are often seen as just giant chunks of compressed water, not stunning works of natural art. during the 2009 season we profiled around 60 icebergs to get computer generated 3D images,' Perry said.īut he had never run into an iceberg like this one before. 'Depending on the ice season, they may have to tow 10 to 20. Icebergs don't move particularly fast, Perry explained, so changing their course can take quite a while, but they don't have to move too many each year. So Perry's company either lassos the big boys with a single boat or corrals them with a net dragged between two boats. It's much cheaper to move the icebergs, even the very large ones, than to disconnect the oil rig and move it, he pointed out: Moving a rig costs millions, while operating a small boat costs about $25,000 per day.

'That's for the smaller ones, we call them growlers,' Perry told. Oceans Limited moves smaller icebergs by training water cannons on them for hours. 'We recorded some upwards of 350,000 tons,' Perry said. Though they don't move particularly quickly - typically one to four knots - they've got enough bulk to do major damage if they hit anything, he explained. Icebergs routinely break off Greenland and float down the Labrador coast, Perry explained, a corridor he called 'iceberg alley.' Along the way, they post a direct threat to deep-water oil installations. And then there it was - a big beautiful arch,' Perry told. 'It was a beautiful day, hardly a wave on the water. Perry was out trawling for icebergs with Oceans Limited, a Canadian company that identifies which of the tremendous floaters are drifting towards stationary deep-water oil rigs, when he found the arch - think Stargate meets portal to Narnia.
