Air Survey
The OPAL air survey launched in September 2009 and is coordinated by Imperial College London. The survey asks people to look for lichens on trees and tar spot fungus on sycamore leaves and then record their results online. The survey is helping scientists learn more about the effects of air pollution, and is supported by a number of organisations including the British Lichen Society.

Famous quotes containing the words air and/or survey:
“A hook shot kisses the rim and
hangs there, helplessly, but doesn’t drop
and for once our gangly starting center
boxes out his man and times his jump
perfectly, gathering the orange leather
from the air like a cherished possession”
—Edward Hirsch (b. 1950)
“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
