Root-filled soils are hot spots of nutrient cycling and carbon storage. New research finds that the world has lost millions of cubic meters of rooted soil volume—and we’re on track to lose much more.
Measuring the Ins and Outflows of Estuaries
Scientists modeled monitoring schemes in three different estuaries to determine instrument layouts that could effectively and efficiently measure exchanges of salt water and freshwater.
Respiration Quotient Variability and Ocean Oxygen Levels￼
Respiration quotients in the Atlantic and Pacific Oceans reflect different water temperature, nutrient stress and phytoplankton community structure, important for regional carbon and oxygen cycling.
High-Frequency Monitoring Reveals Riverine Nitrogen Removal
Years of daily readings provide an unprecedented view into how a submerged aquatic meadow kept nitrogen from reaching the St. Lawrence Estuary as well as insights on how climate change may alter it.
The Burning Tundra
As wildfires blaze through the Arctic, scientists examine the role of landscape characteristics on wildfire ecosystem responses in northern aquatic ecosystems.
Wetlands on the Farm: Potent, Nutrient-Capturing Tools in (Relatively) Small Packages
Constructed wetlands can significantly reduce water pollution from tile-drained farms.
Missouri River Floodplain Expansion, Services, and Resiliency
Benefits might accrue for both wildlife and climate resiliency if more floodplains along the lower Missouri River were allowed to flood.
Impact of Climate on River Chemistry Across the United States
Findings of a new study have implications for water quality, aquatic ecosystem health, and water treatment and management as the world warms.
The Ocean Is Still Sucking Up Carbon—Maybe More Than We Think
Recent studies looking at carbon-sequestering microbes suggest we still have a lot to learn about the ocean’s biological carbon pump.
