Here we present the updated International Soil Radiocarbon Database version 2, which compiles radiocarbon data from over 500 studies at 1,700 locations worldwide. The database provides various soil radiocarbon measurements to improve our understanding of factors that influence the age and time distributions of carbon in soils. While we have made progress expanding the database and improving its structure, important gaps remain in tropical regions, deep soils, and certain measurement types.

Short summary
Tropical peatlands store ancient carbon and have been identified as both being vulnerable to future climate change and taking a long time to recover after a disturbance. It is unknown if these gases are produced from decomposition of 1000-year-old peat. Radiocarbon dating shows emitted gases are young, indicating that surface carbon (rather than old peat) drives emissions. Preserving these ecosystems can trap old carbon, mitigating climate change.

The transport of plant debris in rivers is an important part of the global carbon cycle and influences atmospheric carbon levels through time. We sampled plant debris at the bed of a lowland river and determined the sources as it is transported hundreds of kilometers. Plant debris can persist at the riverbed, but mechanical breakdown reduces its amount, and it is only a small fraction compared to the suspended load. This plant debris and transport patterns need further investigation globally.

Short summary
Planetary warming is increasing seasonal thaw of permafrost, making this extensive old carbon stock vulnerable. In northern Alaska, we found more and older dissolved organic carbon in small drainages later in summer as more permafrost was exposed by deepening thaw. Younger and older carbon did not differ in chemical indicators related to biological lability suggesting this carbon can cycle through aquatic systems and contribute to greenhouse gas emissions as warming increases permafrost thaw.

Short summary
Soils store organic carbon composed of multiple compounds from plants and microbes for different lengths of time. To understand how soils store these different carbon types, we measure the time each carbon fraction is in a grassland soil profile. Our results show that the length of time each individual soil fraction is in our soil changes. Our approach allows a detailed look at the different components in soils. This study can help improve our understanding of soil dynamics.
