How Long Does Iron Linger in the Ocean’s Upper Layers?
A new study refines our understanding of marine residence times of iron, which supports carbon-sequestering sea life, offering valuable data to inform biogeochemical models.
Rising Seas and Agriculture Created Wetlands Along the U.S. East Coast
Most of the tidal marshes along the eastern coast of the United States formed within the past 6,000 years due to a combination of slowly rising seas and European colonization.
Linking Critical Zone Water Storage and Ecosystems
The geology and the structure of Earth’s critical zone control subsurface moisture storage potential and determine the resilience of forest and river ecosystems to drought.
Los Costos Ecológicos de Remover las Plataformas Petroleras Mar Adentro en California
Las plataformas de perforación de petróleo- y gas-mar adentro son hábitats ricos para peces. Eliminarlas por completo resultaría en una pérdida del 95% de biomasa de peces, revela una nueva investigación.
Ideal Temperatures for Carbon Uptake by Subtropical Plants
Air temperatures in coastal ecosystems of Australia routinely exceed the optimum range for photosynthesis, hindering plants’ ability to take up atmospheric carbon.
How Forest Degradation Affects Carbon and Water Cycles
Forest degradation may be as widespread as deforestation in the Amazon, but its impact on energy, carbon, and water fluxes is less well understood.
Lake Ice—and Ecosystems—in a Warming World
Extending ice records and standardizing sampling protocols are among recommendations to help researchers better predict how changing ice cover will affect aquatic ecosystems.
Measuring, Monitoring, and Modeling Ecosystem Cycling
Scientists leverage long-term environmental measurements, emerging satellite observations, and recent modeling advances to examine changes in ecosystem carbon and water cycling.
Sudden Oak Death Taking a Toll on U.S. West Coast
Researchers have been modeling effects of the plant pathogen Phytophthora ramorum on coastal forests in California and Oregon since it arrived on the West Coast 3 decades ago.
