From the coast to the deep sea, changing oxygen levels affect marine life in different ways

Earth's atmosphere maintains a constant level of oxygen, whether it is a wintry, rainy day or hot summer. Across the ocean, oxygen concentrations vary enormously between different places and over time. Sometimes oxygen levels ...

A new electrochemical approach could reduce ocean acidity and remove carbon in the process

In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The ...

Coral reef microbes point to new way to assess ecosystem health

A new study shows that ocean acidification is changing the mix of microbes in coral reef systems, which can be used to assess ecosystem health.

Video: Is there a quick fix for ocean acidification?

Acidification is threatening the ocean's ability to pull carbon dioxide out of our atmosphere, so scientists and startups are looking to ocean-sized antacids to raise its pH.

Impact of climate change on marine life shown to be much bigger than previously known

Fish and invertebrate animals are far more affected by warmer and more acidic seawater than was previously known. This is the conclusion of a study co-led by NIOZ marine biologist Katharina Alter, based on a new analysis ...

Heat stress from ocean warming harms octopus vision

While climate change has led to an increase in the abundance of octopuses, heat stress from projected ocean warming could impair their vision and impact the survivability of the species.

New electrochemical technology could de-acidify the oceans—and even remove carbon dioxide in the process

In the effort to combat the catastrophic impacts of global warming, we must accelerate carbon emissions reduction efforts and rapidly scale strategies to remove carbon dioxide (CO2) from the atmosphere and the oceans. The ...

Satellite measurements show that global carbon emissions are still rising

According to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6), human activities have significantly impacted the planet. As global greenhouse gas emissions (mainly carbon dioxide) have continued ...

Satellites increasingly critical for monitoring ocean health

Playing a huge role in moderating the climate, oceans are fundamental to the functioning of our planet. Understanding more about how seawater temperatures are rising and how oceans are absorbing excess atmospheric carbon ...

Tidal landscapes: A greater carbon sink than previously thought

Mangroves and saltmarshes sequester large amounts of carbon, mitigating the greenhouse effect. New research from the University of Gothenburg shows that these environments are perhaps twice as effective as previously thought.
