Will Ocean Acidification Affect Dungeness Crabs?

Posted On May 18, 2016 by

2016 hasn’t been a good year for the West Coast Dungeness crab fishery. The fishing season that typically spans the winter months – worth $212 million in 2014  – got significantly delayed this year when Dungeness crabs tested high for domoic acid, which sickens humans, and managers shut down the fishery. The crabs had fed heartily on a giant toxic bloom of Pseudonitschia algae, which produce domoic acid, and which were thriving in an unusually warm body of water stalled offshore, affectionately called “the blob.” The bloom also shut down other West Coast shellfish fisheries, too. The lost harvests equal lost income for West Coast communities. San Francisco Bay Area crabber John Mellor says, “If crabs were to disappear from the picture, I think it would be the end of my fishing career at this point.”

Massachusetts Tackling Acidification

Posted On April 6, 2016 by

Count Massachusetts as the latest state to take a step towards fighting ocean acidification. Last week I attended a forum hosted by ocean champions Congressman Bill Keating (MA-9th) and Massachusetts State Representative Tim Madden (D-Nantucket) at the Woods Hole Research Center.  While there, I learned about a state bill sponsored by Rep. Madden to form a commission that will guide the state’s response to ocean acidification.

West Coast Scientists Weigh Actions Against Ocean Acidification and Hypoxia

Posted On April 4, 2016 by

Ten years ago, I was finishing graduate school. I was becoming an expert on how carbon dioxide is stored in the world’s oceans, but – and this seems weird to me now – I hadn’t heard about ocean acidification. Hardly anyone had. Only a handful of scientists had started to realize that as the ocean sops up carbon dioxide from the atmosphere, ocean chemistry changes in ways that can hurt fish, shellfish, and corals.

Just five years later, concern about ocean acidification had grown dramatically, and thousands of people were involved. West Coast shellfish growers were trying to save their hatcheries from the effects of ocean acidification, while scientists were scrambling to offer information and solutions. Ocean Conservancy began working on this issue in 2012, helping bring affected business people, policy makers, and scientists together during the initial search for solutions in Washington State, whose shellfish hatcheries experienced dramatic die-offs of their oyster larvae.

Questioning Our Changing Ocean

Posted On March 22, 2016 by

We all notice when things aren’t quite the same from day to day in our everyday surroundings. Some people’s jobs depend on it. Fishermen, for one, need to notice small changes on the water every day—in the currents, temperatures, and even the fish they’re chasing. Get them together, and these hardworking men and women compare notes on what they’re seeing.

This month, the Maine Fishermen’s Forum in Rockland, Maine attracted fishermen, scientists, managers and community groups to discuss all things fishing in the region. The featured panel of the 3-day event was entitled “Questioning Our Changing Oceans” where fishermen talked about how waters around the world, particularly the Gulf of Maine, are changing.  This discussion was not just sea tales, though. Scientists presented the latest research and data on environmental changes happening in the Atlantic Ocean, and what the future might hold.

An Interview with Coral Reef Expert Danielle Dixson

Posted On March 18, 2016 by

There are some new champions for corals in the nation’s capital. Hawaii’s Senator Hirono and Representative Takai have proposed legislation supporting competitions that encourage innovation among scientists, engineers and coastal managers to develop new and effective ways to keep U.S. coral ecosystems and their neighboring human communities healthy and sustainably managed. We asked tropical reef ecosystem expert Danielle Dixson from the University of Delaware to share her thoughts on what this legislation means for coral reefs, the animals living there, and the people who rely on them.

Our Ocean Remains a Presidential Priority

Posted On February 9, 2016 by

Strong funding proposed for ocean conservation in President Obama’s final budget proposal.

Today, President Obama laid out his final “to-do list” in the form of his proposed federal budget for the coming fiscal year. Ocean Conservancy is pleased to see this administration continue to prioritize the ocean, not least because it contributes more than $343 billion annually to the nation’s GDP and supports 2.9 million jobs through fisheries and seafood production, tourism, recreation, transportation and construction.

You’d be right in thinking President Obama’s proposed budget is a big deal for our ocean.
