Seawater carries a built-in shock absorber for acidity: the carbonate buffer. How it works, why it's wearing thin, and what it means for shell-builders and kelp.

Coralline algae are calcified red algae that paint reefs pink, cement them together and decide where young shellfish settle. Forms, ecology and climate risks.
Dr. Theo Nakamura ·
Crustose coralline algae look like pink paint on reef rock, but they are the settlement cue abalone and urchins need. CCA biology and why restoration depends on it.
Dr. Mara Ellison ·
How oceanographers measure seawater pH and alkalinity, why it's harder than it looks, the sensor zoo from Argo floats to moorings, and what the numbers mean.
Dr. Lena Fischer ·
Rising CO₂ acidifies seawater — but it also fertilises algae. What ocean acidification really does to kelp growth, urchins and whole reef food webs.
Dr. Theo Nakamura ·
Why the sea is salty, why it's slightly alkaline, and why its pH is drifting. A gentle but rigorous introduction to the chemistry that rules marine life.
Dr. Lena Fischer ·
Ocean acidification goes far beyond a falling pH number. Here's where corrosive water actually shows up, what it does to hatcheries and fisheries, and how coasts adapt.
Dr. Lena Fischer ·
The ocean has absorbed about a third of our CO₂ emissions, quietly changing its chemistry. Here's the science of ocean acidification and what it means for sea life.
Dr. Lena Fischer ·
When Pacific oyster larvae began dying in Northwest hatcheries in the mid-2000s, ocean acidification stepped out of the textbook. Here's what happened.
Dr. Lena Fischer ·
Kelp can't open pores for CO₂ like a land plant. Here's how brown algae concentrate carbon for Rubisco underwater — and why 'C4 kelp' is a myth.
Dr. Theo Nakamura ·
Cold water drinks CO2, and the overturning circulation locks it away for centuries. How the ocean's solubility carbon pump works — and what it costs.
Dr. Lena Fischer ·
Adding alkalinity near kelp forests could store carbon and buffer acidification locally. What the chemistry promises, what ecology warns, and the safeguards that count.
