Radionuclide Data from GEOTRACES Improve Particle Flux Estimates
New measurements of multiple radionuclides in the Atlantic Ocean offer a robust constraint on the sinking flux of particles and associated vertical fluxes of biogeochemically important elements.
Tool to Capture Marine Biological Activity Gets Coastal Upgrade
Upwelling hinders an efficient method to estimate a key measure of biological productivity in coastal waters, but accounting for surface temperatures could boost accuracy.
The Tiny Organisms That Transport Silica Across Earth’s Oceans
Phaeodarians play a major role in marine nutrient cycle.
Upper Estuaries Found to Be Significant Blue Carbon Sink
Inland from the seagrass and salt marsh ecosystems that border the ocean, upper estuaries store more carbon than previously realized and could play an important role in mitigating climate change.
Major Uncertainty in Estimates of Carbon Trapped in Soil
A new study reveals discrepancies between global databases and field measurements.
Measuring Emissions from Smoldering Peat Fires
A new study measures emission factors for tropical peatland fires in Malaysia.
Accounting for the Missing Silica in the Marine Sediment Cycle
Cosmogenic silicon-based estimates of the amount of biogenic silica stored in clays along continental margins could explain the large discrepancy in the nutrient’s global marine budget.
Thirty Years of GBC in a Changing World
The outgoing Editor in Chief of Global Biogeochemical Cycles reflects on how research topics published in the journal have adapted and developed since its launch three decades ago.
A New Model Yields a Better Picture of Methane Fluxes
Scientists update an old model with recent findings, allowing for a more accurate understanding of methane dynamics in wetlands.
