Measuring Emissions from Smoldering Peat Fires

Alexandra Branscombe, Freelance Writer

Research Spotlight— A new study measures emission factors for tropical peatland fires in Malaysia. When we picture a wildfire, it’s unlikely we would imagine a smoldering peat fire. These fires burn for days or weeks under the top layer of soil, releasing smoke and heat through the soil and vegetation..... more

Oceanic teleconnection for carbon dioxide

Takamitsu Ito

Commentary— Biogeochemical teleconnection links seemingly unrelated chemical/biological anomalies that are geographically separated by large distances. Bronselaer et al. propose a new mechanism for an interhemispheric teleconnection of air-sea carbon dioxide fluxes in which the upwelling of the Southern.... more

Accounting for the Missing Silica in the Marine Sediment Cycle

Terri Cook, Freelance Writer

Research Spotlight— 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. During the past few decades scientists have increasingly realized that the cycling of silica in.... more

A New Model Yields a Better Picture of Methane Fluxes

Elizabeth Thompson, Staff Writer

From Research Spotlights— Scientists update an old model with recent findings, allowing for a more accurate understanding of methane dynamics in wetlands. Peat-forming wetlands, including bogs and fens, can switch between acting as sources and sinks of methane, a highly potent greenhouse gas..... more

Oceans May Produce Twice as Much Organic Matter as Usually Measured

Sarah Witman, Freelance Writer

From Research Spotlights— Researchers study how oceans respire carbon, reexamining a critical part of the global carbon cycle.  The world’s oceans are one of the biggest carbon pools, or sinks, in the global carbon cycle. Some of this carbon (about 1,000 gigatons) is stored near the ocean’s.... more

New Evidence Challenges Prevailing Views on Marine Carbon Flux

Sarah Stanley, Freelance Writer

From Research Spotlights— Small, slow-sinking organic particles may play a bigger role than previously thought in the transport of carbon below the surface ocean.  Earth’s oceans play a major role in limiting the concentration of carbon dioxide in the atmosphere. Carbon dioxide dissolves in.... more

New Baseline for Understanding Arctic Oxygen and Nutrient Fluxes

Terri Cook, Freelance Writer

From Research Spotlights— Significant spatial and temporal patterns emerge from the first pan-Arctic comparison of oxygen demand in marine sediments.  The breakdown of organic matter in marine sediments is a crucial ecosystem function that liberates energy and recycles biologically important.... more

New statistical model emphasizes role of spatial correlation

Editor’s Highlight—   This paper presents a statistical methodology to assess uncertainties in ocean chlorophyll trends. It provides strong evidence that significant differences exist in regional and global trends when compared with linear temporal models that have been widely used in other work. This.... more

Impacts of ENSO on air-sea oxygen exchange: observations and mechanisms

Editors’ Highlights­­— The exchange of oxygen between the air and sea reflects the physical and biogeochemical processes of the ocean and their interactions. Our understanding of the responses of the above-ocean processes to climate change could be improved with insights into the inter-annual variability.... more
