With a deficit of sediment needed to compensate for relative sea level rise, a new study demonstrates that organic material cannot be ignored in evaluating mass and volume accumulation rates.

Downhill from Here: Landscape Positions and Greenhouse Emissions
In comparing soils from two tundra wetland landscape positions, landscape position is found to matter, and toeslopes are associated with higher greenhouse gas production.
Soil Carbon May Not Remain Bogged Down in a Warmer World
Carbon was lost from an experimentally warmed boreal peatland much faster than it took to accumulate. Elevated CO2 had little effect on stored carbon, requiring re-evaluation of model assumptions.
Marine Nitrous Oxide Emissions off Northwest Europe
Continental shelves and estuaries are natural sources of nitrous oxide, but current global estimates of these emissions carry a lot of uncertainty, a problem that calls for regional studies.
Lost in the Everglades
Living in Geologic Time: An unintentional adventure in the River of Grass shows how Florida has changed dramatically over 15,000 years of human habitation.
Coastal Wetlands Save $1.8 Million per Year for Each Square Kilometer
The protective value of a plot of wetlands varies widely based on the county it shields from storm-related property damage.
Representing Estuaries and Braided Rivers as Channel Networks
The human eye is quite good at identifying channel networks among the rich patterns exhibited by estuaries and braided rivers, but computers have a harder time doing so. Could they do better?
Scientists Search for Deltas on Saturn’s Largest Moon
Saturn’s moon Titan has rivers that empty into seas…but where are the deltas?
Improving Estimates of Coastal Carbon Sequestration
A new two-model approach could reduce uncertainties in calculated rates of “blue carbon” accumulation within soils of seagrass, tidal marsh, and mangrove habitats.
Peatlands Are Drying Out Across Europe
Peatlands are some of the world’s largest reservoirs of soil carbon, but new research finds that in Europe they are drying out, putting them at risk of turning from carbon sinks to carbon sources.
