Rivers deliver freshwater, nutrients, and carbon to Earth's oceans, influencing the chemistry of coastal seawater worldwide.

Single-celled algae in the ocean known as coccolithophores play an important role in the marine carbon cycle when they take ...

Now that we have the experiment started, as Hannah discusses in her most recent post, we’re done sorting amphipods and have moved onto doing seawater chemistry. Every morning we test six water samples ...

Efforts to boost the ocean’s carbon-storing capacity by making seawater more alkaline could wreak havoc on the marine food web, researchers have warned. Ocean alkalinity enhancement is a proposed ...

The world’s oceans are becoming dangerously acidic. A controversial proposal would raise the pH — by mixing chemicals into ...

To mitigate climate change, human-made carbon dioxide (CO2) emissions must be reduced as quickly and drastically as possible. Additionally, some of the CO2 already emitted needs to be safely removed ...

In this episode of C&EN Uncovered, host Craig Bettenhausen speaks with C&EN reporter Fionna Samuels about her recent C&EN cover story concerning ocean alkalinity enhancement as a method to combat ...

Climate change is already fueling dangerous heat waves, raising sea levels, and transforming the oceans. Even if countries ...

The study adopted an approach with moderate perturbations to seawater chemistry: CO₂-equilibrated Ocean Alkalinity Enhancement. With this approach, the alkalised water that has already absorbed CO 2 ...
