Congress Wants More Attention on Ocean Acidification

Last month, federal lawmakers signaled their concern for healthy coastal communities when six House Republicans and Democrats introduced a bill directing the National Oceanic Atmospheric Administration (NOAA) to assess the vulnerabilities of these communities to ocean acidification. The bill, entitled the Coastal Communities Ocean Acidification Act of 2015 (H.R. 2553) takes an important step in helping these impacted individuals understand what acidification means for them specifically, and what can be done to protect themselves and their marine resources such as fisheries.

Although ocean acidification has generally been associated with oyster, mussel and clam die-offs, coral reefs are also threatened, and scientists are increasingly finding that important fisheries such as king and Dungeness crab, and summer flounder, won’t fare well in an increasingly acidic world. Given the millions of livelihoods at stake, we applaud Representatives Chellie Pingree (ME-1) and Vern Buchanan (FL-16) who introduced the bill along with their cosponsors for using foresight in trying to get ahead of this issue, and protect the jobs and way of life for thousands of individuals and families.

Where Are the “Hotspots” For Ocean Acidification?

Posted On February 24, 2015 by

By now, coastal communities are asking: “Who’ll be hit next by ocean acidification? And what can people do?” Until now, we haven’t known where exactly in the United States ocean acidification is most likely to affect marine ecosystems, and where the effects on people could be greatest. (Fortunately, several forward-thinking states are already studying the issue and recommending next steps!)

Three years ago, I teamed up with an economist, a human geographer, and another ocean acidification scientist to lead a study that would identify ocean acidification “hotspots” around the United States – places where ocean changes will be large and coastal communities depend heavily on shellfish harvests, but where people don’t have many resources to guard against losses of these harvests. We gathered a group of 20 science and policy experts to study the issue at the National Science Foundation-funded National Socio-Environmental Synthesis Center (SESYNC). Since then, we’ve synthesized information about the oceanography, shellfish harvests, and coastal communities across the United States in a formal risk assessment. We’ve just published our results in Nature Climate Change this week.

Video: Ocean Acidification – A Threat to Economies and Cultures Around the World

Posted On August 21, 2014 by

Over these past three months, my blog series has taken you around the world and into the lives of marine dependent communities at risk from ocean acidification.  Hopefully this journey did for you what it did for me: showed how ocean acidification has the power to alter whole communities, and how these communities are in dire need of research, guidance and infrastructure to prepare for the challenges ahead.

Sight and Smell: How Traditional Methods Won’t Hold up Against Ocean Acidification

Posted On July 25, 2014 by

Ocean acidification is invisible to the naked eye.  It’s not something we can smell, not something we can feel with our fingers.  But in many parts of the world, that’s just how fishermen and shellfish farmers assess the water they work in.

Right now, the methods we have to understand and respond to ocean acidification are expensive, requiring a lot of equipment.  For example, oyster farmers in the Pacific Northwest rely on ocean monitoring systems that tell them the condition of the water, high-tech hatcheries that give them a controlled environment in which to rear their oysters, and buffering systems that allow them to neutralize the water coming in and make it suitable for oyster growth.
