The shells of some marine snails are dissolving as the seas around Antarctica become more acidic, threatening the food chain, according to a study published in the journal Nature Geoscience.
Oceans soak up about a quarter of the carbon dioxide released into the atmosphere each year; as CO2 levels in the atmosphere increase from the
The shells of marine snails – known as pteropods – living in the seas around Antarctica are being dissolved by ocean acidification according to a new study published this week in the journal Nature Geoscience. These tiny animals are a valuable food source for fish and birds and play an important role in the oceanic carbon
Scientists have known for years that greenhouse gasses are altering the chemical makeup of our oceans.
More and more carbon dioxide is dissolving into salt water, creating carbonic acid. That changes the ocean’s pH, or acid-alkaline balance.
And it’s hitting harder in Alaska.
On Monday, Congress was called on by a leading environmental organization to address the increasing threat to sea life that has been caused by decades of warming ocean temperatures and C02 pollution.
The action by Center for Biological Diversity included submitting a detailed letter to the House of
Peering into the microscope, Alan Barton thought the baby oysters looked normal, except for one thing: They were dead.
Slide after slide, the results were the same. The entire batch of 100 million larvae at the Whiskey Creek Shellfish Hatchery had perished.
In the United States and other coastal nations, ocean acidification has quickly become a common topic of scientific research. Ocean acidification also has become a public concern as news headlines warn of this potentially threatening byproduct of global climate change.
The NOAA Ocean Acidification Program (OAP) works to prepare society to adapt to the consequences of ocean acidification and conserve marine ecosystems as acidification occurs. Learn more about the human connections and adaptation strategies from these efforts.
Adaptation approaches fostered by the OAP include:
Using models and research to understand the sensitivity of organisms and ecosystems to ocean acidification to make predictions about the future, allowing communities and industries to prepare
Using these models and predictions as tools to facilitate management strategies that will protect marine resources and communities from future changes
Developing innovative tools to help monitor ocean acidification and mitigate changing ocean chemistry locally
Drive fuel-efficient vehicles or choose public transportation. Choose your bike or walk! Don't sit idle for more than 30 seconds. Keep your tires properly inflated.
Eat local- this helps cut down on production and transport! Reduce your meat and dairy. Compost to avoid food waste ending up in the landfill
Make energy-efficient choices for your appliances and lighting. Heat and cool efficiently! Change your air filters and program your thermostat, seal and insulate your home, and support clean energy sources
Reduce your use of fertilizers, Improve sewage treatment and run off, and Protect and restore coastal habitats
You've taken the first step to learn more about ocean acidification - why not spread this knowledge to your community?
Every community has their unique culture, economy and ecology and what’s at stake from ocean acidification may be different depending on where you live. As a community member, you can take a larger role in educating the public about ocean acidification. Creating awareness is the first step to taking action. As communities gain traction, neighboring regions that share marine resources can build larger coalitions to address ocean acidification. Here are some ideas to get started:
