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.

Help Us Say No to Risky Arctic Drilling

Breaking: The U.S. government is beginning to make plans for future offshore oil and gas operations—and those plans could open Arctic waters to risky drilling.

This follows Shell Oil’s decision to abandon Arctic drilling this summer, after an accident-plagued 2012.

If a disaster like BP Deepwater Horizon happened in the Arctic, spill response would be even more challenging. The Arctic’s sea ice, freezing temperatures, gale force winds, and lack of visibility could make cleanup next to impossible.

Nowhere to Hide: More Than Fish May be Impacted by Plastic Pollution

Posted On July 23, 2014 by

The problem of plastics in the ocean has been receiving a lot of attention recently.  You might even say it’s “trending.” As it should be.  Ideas about how to clean up the mess are circulating around the internet, including input from professional ocean scientists on how likely these ideas are to really be effective.  But the cutting edge of scientific inquiry is assessing the extent to which plastics in the ocean – especially tiny fragments called microplastics – are impacting marine life.  A recent study suggests it’s not just fish that might be eating plastic.

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.

Where Has All the Plastic Gone?

Posted On July 2, 2014 by

We live in a society of plastics, no doubt about it. And as our insatiable appetite for plastics has increased year after year, so too has the quantity of plastics flowing into our ocean. The magnitude of this input and the ultimate resting place of ocean plastic pollution, however, remain up for debate.

In a study just published in the Proceedings of the National Academy of Sciences (PNAS), Dr. Andres Cozar and his colleagues estimate the total amount of floating plastic debris in the ocean is several orders of magnitude less than the 1 million tons extrapolated from data published by the National Academy of Sciences in the 1970s.

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

Posted On June 30, 2014 by

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.
