Increases in temperature as a result of climate change are mirrored in lake waters where temperatures are also on the rise. A new study, by Dr. Martin Dokulil, retired researcher from the Institute for Limnology at the University of Innsbruck in Austria, forecasts surface water temperatures in large Austrian lakes for 2050 and discusses the impact on the lakes' structure, function and water quality. The research is published online in Springer's journal Hydrobiologia.

Lake Bonney in Antarctica is perennially covered in ice. It is exposed to severe environmental stresses, including minimal nutrients, low temperatures, extreme shade, and, during the winter, 24-hour darkness. But, for the single-celled organisms that live there, the lake is home. To study them, Dr. Rachel Morgan-Kiss from the University of Miami, Ohio, and her team went to Antarctica to sample the ice-covered lake. The article describing her method will be published April 20, in the JoVE (the Journal of Visualized Experiments)

Policymakers are very familiar with land-use planning. But what is the best approach for planning uses of America's coastal waters and oceans? That question has gained importance since President Obama formed the National Ocean Council last summer and charged it with developing an ecosystem-based stewardship policy for the nation's oceans, coastal waters and the Great Lakes.
