Layers of lake sediment are removed at intervals from a core. In a laboratory, contaminants and biological remains are analyzed from select sediment layers to understand lake history and reconstruct environmental changes that often predate periods of direct monitoring.
Canadian researchers have used the mud at the bottom of lakes like a time machine to show that tar sands oil production in Alberta, Canada, is polluting remote regional lakes as far as 50 miles from the operations.
An increasingly large share of U.S. oil comes from Canada's tar sands. There are environmental consequences of this development, but until recently, Canadian regional and federal governments left it to the industry to monitor these effects.
U.S. employers added 155,000 jobs in December, a steady gain that shows hiring held up during the tense negotiations to resolve the fiscal cliff. But the unemployment rate remained at 7.8 percent last month.
