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.

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?

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.

Resilient Peatlands Keep Carbon Bogged Down
Boreal peatlands contain some of the world’s largest reservoirs of soil carbon, and new research suggests some peatlands may hold on to that carbon even as the climate changes.
