Estimating Lake Evaporation Just Got Easier
A new method standardizes freshwater lake measurements and shows they are losing a fifth of their inflow to evaporation.
Lake Michigan’s Salinity Is on the Rise
Road salt is primarily to blame for the shift, though the water remains within safe levels for now.
Sediments Suggest Vikings May Have Been the First to Settle the Azores
A multidisciplinary team studying lake sediments and climate change found evidence that the archipelago was inhabited 700 years earlier than historical sources claim.
Hot Lakes in a Cold Climate
Arctic warming may release less carbon dioxide from high latitude lakes but increase their climate impact by releasing more methane.
A New Technique Could Identify Algae from Space
Some types of algal blooms produce dangerous toxins, while others are relatively harmless to humans.
Cyanobacteria Blooms Exceed WHO Thresholds in Midwest Lakes
A study of 369 lakes across the Midwest finds that many of them, especially those close to agriculture, have high concentrations of harmful algal bloom-causing cyanobacteria.
An Explanation, at Last, for Mysterious “Zen Stones”
Laboratory experiments re-create the thin, icy pedestals that support some rocks in nature, revealing that sublimation plays a key role in the formation of these rare and beautiful structures.
