The deep ocean is fixing carbon in ways no one expected

Researchers have uncovered surprising evidence that the deep ocean’s carbon-fixing engine works very differently than long assumed. While ammonia-oxidizing archaea were thought to dominate carbon ...

Managing Carbon Stocks Requires an Integrated View of the Carbon Cycle

Managing carbon stocks in the land, ocean, and atmosphere under changing climate requires a globally integrated view of carbon cycle processes at local and regional scales. The growing Earth ...

The major ion chemistry of seawater was closely coupled to the long-term carbon cycle during the Cenozoic

Determining past changes in the composition of seawater is important as seawater chemistry can be thought of as an integrated record of geological processes that drive the carbon cycle. In addition, ...
