When the River Meets the Sea: Estuary Sediments and Hypoxia
Scientists know that low-oxygen dead zones are growing worldwide. New research sheds light on what that will mean for estuary systems if trends continue.
Leaf-Cutter Ants Boost Carbon Dioxide Emissions from Soil
Leaf-cutter ant nest openings emit up to 100,000 times more carbon dioxide than surrounding soil, a new study shows.
Organic Particles Affect Carbon Cycling in Boreal Waters
Dissolved organic carbon receives much of the focus in aquatic research, but a new study suggests that bulkier particulate matter may play a significant role in regulating carbon dioxide emissions.
How Nitrogen Contributes to Permafrost Carbon Dynamics
Nitrogen released into the soil from thawing permafrost in the Arctic could accelerate soil carbon decomposition and alter carbon dynamics, with global implications.
Hydrology Dictates Fate of Carbon from Northern Hardwood Forests
As spring snowmelt and fall rains inundate northern hardwood forests with moisture, soil bacteria get moving and increase carbon exports to the atmosphere and into nearby water bodies.
The Acid Tongue of Climate Change Strikes Our Streams
Clear air policies have led to dramatic reductions in acid rain and improved ecosystem health, but it now appears that climate change could counteract those gains.
What Lies and Waits Beneath Lake Ice?
Rarely made detailed measurements of carbon dioxide and methane under lake ice reveal a story more complex than simple models of gas buildup, with surprising findings for climate change impacts.
Budgeting Ozone-Depleting Emissions from Coastal Tidal Marshes
Brackish wetlands and their salt-tolerant vegetation are significant methyl halide emitters. The natural emissions add chlorine and bromine to the stratosphere, which break down ozone.
Restored Wetlands Could Lower Local Surface Temperatures
A 3-year study of wetlands and cropland in a major California delta highlights the need to consider the physical effects of vegetation when planning land use changes.
