In freshwater vegetation flats upstream of the Chesapeake, chemical reactions create molecules that raise pH levels in the bay.
Physical and biogeochemical interactions
Dead Reefs Keep Calcifying but Only by Day
A new measurement technique has revealed that turf algae communities colonizing dead reefs have a dual role, adding new mineral material to the reefs during the day and taking it away at night.
Eddies Influence Productivity in the Subtropical Open Ocean
Ocean eddies may help recycle nutrients within giant current systems that encircle “desert” surface waters.
Interpreting Mosaics of Ocean Biogeochemistry
Advances in technology and modeling capabilities are driving a surge in progress in our understanding of how ocean ecosystems mix and mingle on medium to small scales.
Unraveling Hemispheric Ocean Nitrate Supply Pathways
Subsurface measurements of nitrogen and oxygen isotope ratios in nitrate reveal a predominantly southern hemisphere supply of nitrate to the equatorial Pacific.
What Proportion of River Nutrients Reaches the Open Sea?
Results of the first geographically based estimates of river nutrient supply indicate that 75% of dissolved nitrogen and 80% of phosphorus reach the open ocean.
Permafrost Area Is Sensitive to Key Soil and Snow Physics
Accounting for key soil and snow variables shows a much higher impact on simulated permafrost area than uncertainties in land cover and climate data.
An Unprecedented View of Biogeochemistry off India's West Coast
Yearlong study reveals seasonal changes in oxygen levels, nutrient availability, and plankton growth.
Satellites Reveal Dynamics of Suspended Mineral Particles
A case study of the Irish Sea evaluates the use of ocean color data to measure the optical properties of sedimentary particles in offshore waters.
Underwater Gliders Find Swirling Vortices of Warm, Salty Water
Vortices formed off the west coast of Sardinia could play a large role in Mediterranean water circulation and mixing and are significant for marine ecosystems and regional climate.
