Disappearing Ponds Bad News For High Arctic

When they went back last year, after an absence of a year, permanent ponds which previously had been up to a metre deep were drastically shrunken or even dry. Their measurements had shown the water had been going down, but they were taken aback to find that about 40 well-studied pools — among them Camp Pond, Cape Herschel Lagoon and Beach Ridge Pond — were fractions of their former size, or totally gone. These ponds were substantial bodies of water; Cape Herschel Lagoon, once 160 metres by 35 metres and a metre deep, "had only a small shallow puddle" (23 metres by 11 metres and 10 centimetres deep) in one basin when the scientists sampled it on July 13, 2006. Camp Pond, 20 metres by 40 metres, and Beach Ridge Pond, 100 metres by 60 metres, were completely dry. http://www.cbc.ca/technology/story/2007/07/02/onds-arctic.html [Proofreader's note: this article was edited for spelling and typos on July 3, 2007]
