Posted on SeafoodNews.com: 30 Apr 2014 The problems of ocean acidity harming the marine food chain and ultimately upending West coast fishery produdtion could be coming much sooner than expected. In a new paper published this week, NOAA scientists have found large scale evidence of severe dissolution of the shells of

Ocean acidity is dissolving shells of tiny snails off U.S. West Coast
Posted on Science Daily: 30 Apr 2014 — Source: National Oceanic and Atmospheric Administration — Summary: Biologists have found the first evidence that acidity of continental shelf waters off the U.S. West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon,
Sea Change: Vital Part of Food Web Dissolving
Posted on The Seattle Times: By Craig Welsh — Scientists have documented that souring seas caused by CO2 emissions are dissolving pteropods, a key marine food source. The research raises questions about what other sea life might be affected. It didn’t take long for researchers examining the tiny sea snails

A low-cost fluorescent sensor for pCO2 measurements
Posted on OA: 15 Apr 2014 Global warming is believed to be caused by increasing amounts of greenhouse gases (mostly CO2) discharged into the environment by human activity. In addition to an increase in environmental temperature, an increased CO2 level has also led to ocean acidification. Ocean acidification and rising
