Science in the hands that need it: Turning the tide on ocean acidification in New Zealand

Posted On August 1, 2014 by

In 2013, I worked on a shellfish boat in New Zealand.  We used hydraulic systems to lift lines of shellfish out of the water, conveyor belts to sort them, and packaged mussels by the thousands in giant, half ton sacks.  A far cry from the low-tech nighttime dredging from a longtail boat I saw in Thailand.

With this technological edge, surely New Zealand shellfish farmers are less vulnerable to ocean acidification than those in regions like Southeast Asia.

But that is not what I found.  I found shellfish farmers in New Zealand to be highly vulnerable to ocean acidification. This wasn’t because the country lacked the technology or knowledge to be resilient, but because that technology and knowledge wasn’t making it into the hands of the shellfish farmers.

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

Posted On July 18, 2014 by

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.

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.

The World is Ready For the Our Ocean Conference, and the Conference is Ready For You

On June 16-17th, Secretary of State John Kerry and the Department of State will bring together scientists, stakeholders and leaders from around the world for the Our Ocean Conference. This international event will focus on three pressing ocean issues: sustainable fisheries, marine pollution, and ocean acidification. I am honored to be speaking on the ocean acidification panel at this conference.

I will be sharing stories I gathered from my year-long Watson Fellowship, studying how ocean acidification might affect human communities around the world. Over that year, I saw just how far-reaching ocean acidification’s impacts could be. We already know, from our experience in the US, that it hurts shellfish growers and the communities that depend on them. But around the world, there are whole countries and communities that depend on threatened species, such as coral for tourism, and fish for food and livelihoods. The stories I heard convinced me that we need to raise awareness and take action against ocean acidification at the international level. Here are some of those stories:

East Coast State Legislators Begin Investigations on Ocean Acidification

When people think about the state of Maine, images of lobsters and lighthouses usually spring to mind. For the state of Maryland, people think of blue crab and the rivers feeding into the Chesapeake Bay.  Both states are closely associated with rich maritime traditions, however a change in ocean chemistry is rapidly occurring that could jeopardize not only their maritime way of life, but also the jobs and economic benefits that the ocean and coastal waters provide.

Ocean acidification is caused by carbon pollution from factories, cars, and power plants being absorbed by the ocean, turning it more acidic. In fact, the ocean absorbs roughly 30% of all carbon pollution we put into the atmosphere, and local pollution running off from the land into coastal areas can make acidification worse. Animals that have shells, like oysters, clams, mussels and crabs have trouble surviving in increasingly acidic water. In the Pacific Northwest  ocean acidification has damaged these animals, contributing to billions of baby oyster deaths, significantly impacting the hatcheries and oyster operations in these regions. The impact of ocean acidification on other animals, such as lobsters and fish, are not well understood.

Mass Shellfish Die-Offs in Canada: Is Ocean Acidification to Blame?

Posted On March 4, 2014 by

News broke last week that a company called Island Scallops in British Columbia, Canada, had lost three years’ worth of business – 10 million scallops and $10 million. The CEO, Rob Saunders, identified ocean acidification as the culprit.

Now, there is rightly some attention to being paid to the mass shellfish die-offs in Canada. An oyster farm in the region has also come forward with tales of oyster deaths. The owner of the oyster farm was quoted in Canada’s Globe and Mail as saying, “It’s hard to say [what is causing these deaths] without having somebody there monitoring what’s going on.”
