Climate change may halve omega‑3 fatty acids in fish and the organisms they eat

You've probably heard that eating fish and other seafood is good for your health. One of the main reasons is that seafood is an excellent source of two important omega-3 fats called EPA and DHA.

Why marine heat waves and acidification strike together

Marine heat waves and extreme ocean acidification events are each damaging on their own. But when both stressors hit simultaneously, their individual effects can be exacerbated.

Study suggests three-quarters of Indo-Pacific coral reefs could drown as sea levels rise

Nanyang Technological University, Singapore (NTU Singapore) scientists have found that most coral reefs across the Indo-Pacific may struggle to grow fast enough to keep pace with accelerating sea-level rise. Their study found ...

Tiny fossils crack a Cretaceous cold case: Ocean acidification triggered one of the ocean's most severe extinctions

A 113-million-year-old marine murder mystery may finally be solved. Using chemical clues locked inside microscopic fossils, Northwestern University scientists found evidence that ocean acidification drove one of the largest ...

Ocean acidification emerging as a planetary signal linking today's carbon emissions to Earth's deep-time memory

When most people hear the phrase "ocean acidification," they think of coral reefs, shellfish or declining fisheries. Those concerns are real. But while working on our recent research, I found myself asking a different question: ...

Researchers link the mass extinction of once-dominant marine groups to intolerable heat, diminished oxygen in oceans

A new Stanford-led study offers the clearest picture yet of how some ocean life survived our planet's biggest mass extinction while most animals did not. About 252 million years ago, 96% of marine species and 70% of land ...

Ocean acidification may be shrinking the brains of the world's most intelligent invertebrates

An ongoing research project exploring the effects of rising levels of oceanic CO2 on squid neurology reveals that exposure to future levels of ocean acidification could shrink their brain volume by around 50%. This severe ...

Ancient oceans began suffocating millions of years before Triassic mass extinction, geologists discover

One of the most devastating extinctions in Earth's history is best known for what didn't die—dinosaurs. But the end-Triassic extinction 201 million years ago wiped out roughly 60% of Earth's species, and scientists are still ...

Tropical cyclones now release ocean carbon, but warming could flip role by 2035

The ocean is an important carbon sink that absorbs 20–30% of the total anthropogenic CO2 emissions in the industrial era (1.0–3.0 Pg annually, 1 Pg = 1015 g). Tropical cyclones are among the most devastating weather systems ...

Ocean acidification is ruining reef fishes' social lives, study finds

A new study from Adelaide University has found that when ocean acidification makes reef habitat less complex, the fish living there gather in smaller shoals that offer less social protection.
