Alaska in the Spotlight: Supporting Communities Facing the Big Risks From Ocean Acidification

Posted On July 29, 2014 by

The total risk of Alaska’s boroughs and census areas from ocean acidification. Red areas are at highest risk, while blue areas are at lowest risk. Population size (circles), commercial harvest value (dollar sign size), and subsistence fishing significance (fish icon size) contribute to the total risk. Reprinted from Progress in Oceanography.

We know that some people will be more at risk than others as a result of ocean acidification. We have seen this with oyster growers in the Pacific Northwest.  Scientists are now trying to determine what puts certain regions at greater risk than others from ocean acidification. Before I came to Ocean Conservancy, I helped lead a study on this question for Alaska, and it’s just been published in Progress in Oceanography this week.

My coauthors and I found that many of southwest and southeast Alaska’s boroughs and census areas (similar to counties or parishes in other states) face social and economic risk from ocean acidification – namely, many of the foods they eat and sell for income, all coming from the sea, are threatened by changes in the ocean’s chemistry.

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.

The Thing You Can’t Measure: Ocean Acidification Threatens Culture and Identity in New Zealand

These last two weeks, I have shared stories of how ocean acidification could affect economies around the world. These tangible impacts can be measured by changes in jobs, access to resources and overall economic condition. But what about the impacts you can’t measure? What will those changes be, and how will they affect people?

Throughout my Watson Fellowship, I sought to understand these intangible impacts. These hard-to-measure threats to things like one’s sense of place, identity and culture may not have dollar signs behind them, but to many of the people I spoke with, they were of utmost importance.

To explain this, I will share what I learned about the value of marine resources in New Zealand. There are two strong cultural lineages in New Zealand – the indigenous Maori community, and the descendants of Western settlers, who came primarily from England. Despite their distinct backgrounds, my conversations with both groups came to the same conclusion: the availability of seafood in New Zealand, particularly shellfish, is a matter of identity. If that seafood is gone, then the identity of the entire country suffers.

The Ground Beneath Their Feet: The Threat of Ocean Acidification to a Small Island

Posted On July 10, 2014 by

What if the ground beneath your feet, the very foundation of your life and livelihood, was at risk of eroding away?  What if the very thing from which you and your community draw 95% of your wealth was at risk of disappearing?

This is the reality that Aitutaki, a small island in the Cook Islands, and many other small islands around the world, are facing.  Aitutaki, and its stunning lagoon, is protected by a coral reef.  Powerful ocean waves crash on the edges of the reef, but because coral reduces wave strength by 97%, the lagoon and the coral sand beaches remain still and calm.  The value of this protection, and the environment it creates, cannot be overstated.

What Will Ocean Acidification Mean for a Small Town in Peru?

At the Our Ocean Conference, I had five minutes to tell an international audience why ocean acidification is a problem for people around the world. With my blog series this summer, we’re going to explore this further. I will share the stories of the people I met last year; stories that taught me how ocean acidification could threaten economies and cultures; stories that taught me the crucial need for increased monitoring, research and technology; and stories that taught me how all of us have a role to play in addressing ocean acidification.

Let’s start with the threat to economies. Just how important are the resources threatened by ocean acidification? To answer this, I want to tell you about two places that are very special to me: Sechura, in Northern Peru, and Aitutaki, in the Cook Islands. First, I will tell you about the scallop farming region of Sechura, and in my next post the tropical paradise of Aitutaki.

A Modest Pledge Makes a Big Difference for Ocean Acidification Research and Collaboration

Posted On June 25, 2014 by

 

The right-hand end of the long, low pinkish building across the harbor houses the International Atomic Energy Agency Laboratory in La Condamine, Monaco, which hosts the Ocean Acidification International Coordination Centre.

Despite this week’s excited headlines about ocean research and conservation during Secretary Kerry’s “Our Oceans” conference, you still might have missed Prince Albert of Monaco’s Monday announcement that the U.S. State Department and Department of Energy have pledged a total of $640,000 to the Ocean Acidification International Coordination Centre (OA-ICC), based at the International Atomic Energy Agency’s (IAEA’s) Monaco lab.

Momentum to Address Ocean Acidification Grows at the Our Ocean Conference

Posted On June 20, 2014 by

On Monday and Tuesday, I witnessed something inspiring.  I watched my Secretary of State, John Kerry, passionately and forcefully address the pressing ocean issues of our time.  I watched leaders from around the world come together and commit to protecting the ocean—the precious resource that, as my fellow panelist Carol Turley said, “Is what makes Earth different from all other planets.”

Above all, I listened and watched as ocean acidification, an issue I have been passionate about for years, became a focal point of dialogue on ocean conservation. President Obama and Secretary Kerry spoke strongly, and did not try to weasel their way around the issues at hand.  Sir David King, Special Representative for Climate Change in the United Kingdom, said, “Climate change, together with ocean acidification, represents the greatest diplomatic challenge of our time.”  Secretary Kerry called for a change in politics, saying “Energy policy is the solution to climate change.”
