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.
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.
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.
