Water Survey
The OPAL water survey launched in May 2010 and is coordinated by University College London (UCL). The survey asks people to go pond-dipping and identify the invertebrates living in their local pond or lake. Using this information they can then find out how polluted the water is, as some creatures are more tolerant of pollution than others. Results are collected online and will help scientists learn more about lakes and ponds across England.

Famous quotes containing the words water and/or survey:
“What a dissimilarity we see in walking, swimming, and flying. And yet it is one and the same motion: it is just that the load- bearing capacity of the earth differs from that of the water, and that that of the water differs from that of the air! Thus we should also learn to fly as thinkers—and not imagine that we are thereby becoming idle dreamers!”
—Friedrich Nietzsche (1844–1900)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
