Welcome to our blog! Here you can explore hot ocean topics and find postings that highlight a few of the most interesting new articles added in the Center for Ocean Solution’s Pacific Ocean Library. We hope to inspire you to participate in the ongoing conversation and encourage you to explore the resources of the Pacific Ocean Library.

April 2012: Managing and Mitigating Ocean Acidification in California and the Pacific

In April, we focus on ocean acidification. How is carbon dioxide (CO2) affecting our oceans, what are the consequences of increased levels for marine ecosystems, and what can we do to manage and mitigate rising CO2 in our oceans? As California takes steps to better understand the impacts of ocean acidification and how to develop a response, state leaders recently asked the Center for Ocean Solutions to analyze the issue.  Read more...

Today's Unprecedented Ocean Acidification

When an environmental issue merits a full-scale editorial in The New York Times, it’s a sign that the issue has broken out of the scientific literature and into the popular consciousness. Last Friday, 10 March 2012, The Times ran an editorial highlighting the human-caused change in the world’s ocean chemistry. One consequence of human-released carbon dioxide in the atmosphere is an ocean significantly more acidic than it was just a few generations ago, and this change is accelerating in tandem with our carbon dioxide emissions.

Ocean acidification, or the increase of low-pH, corrosive ocean waters, certainly qualifies as a process that impairs water quality.   Now the Environmental Protection Agency (EPA) has created guidance to address ocean acidification under the Clean Water Act. 

On November 15th, the EPA released a Memorandum to guide regions and states in reporting the impacts of ocean acidification under Section 303(d) of the Clean Water Act, which requires states to submit a list of impaired water bodies that do not meet water quality standards, and develop total maximum daily loads (TMDLs) for these waters.  A TMDL is a calculation of the maximum amount of a pollutant that a body of water can receive and still safely meet water quality standards.  In the case of ocean acidification, the main pollutant in question is carbon dioxide (CO2).  Read more...
