The Domino Effect of Freshwater Suffocation
As lakes and reservoirs become anoxic, they can promote poor water quality downstream.
Stormwater Ponds Are Carbon Sources, Not Sinks
New research from Florida tracks carbon dioxide and methane emissions from human-created waterways.
Newly Discovered Lake May Offer a Glimpse into Antarctica’s Past
Scientists dive in—metaphorically—to Lake Snow Eagle, only recently revealed through ice-penetrating radar.
New Observations Reveal Ancient Subglacial Water Paths
Analyses of new shipboard and ROV observations of bedrock channels carved by floods and outbursts from subglacial lakes under Antarctica shed light on complex subglacial processes.
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.
