Posted on EPOCA: 23 Jan 2012 Nearly one-third of CO2 emissions due to human activities enters the world’s oceans. By reacting with seawater, CO2increases the water’s acidity, which may significantly reduce the calcification rate of such marine organisms as corals and mollusks. The extent to which human activities have raised the

UNESCO: Vital fate of oceans on Rio+20 agenda
Posted on RTCC: 23 January 2012 By Tierney Smith Proposals regarding oceans have been included in the drafts for Rio+20 The head of the Intergovernmental Oceanographic Commission at UNESCO has told RTCC that acidification of the world’s seas must be on the agenda at the Rio+20 summit. Since the industrial revolution,
Detecting regional anthropogenic trends in ocean acidification against natural variability
Posted on EPOCA: 23 Jan 2012 Since the beginning of the Industrial Revolution humans have released ~500 billion metric tons of carbon to the atmosphere through fossil-fuel burning, cement production and land-use changes. About 30% has been taken up by the oceans. The oceanic uptake of carbon dioxide leads to changes
Broadcast study of ocean acidification to date helps scientists evaluate effects on marine life
Posted on EPOCA: 23 Jan 2012 Might a penguin’s next meal be affected by the exhaust from your tailpipe? The answer may be yes, when you add your exhaust fumes to the total amount of carbon dioxide lofted into the atmosphere by humans since the industrial revolution. One-third of that
The effects of ocean acidification and upwelling conditions on the growth and calcification of the red abalone (Haliotis rufescens)
Posted on EPOCA: 16 Jan 2012 Upwelling events along the California coast expose invertebrates to low dissolved oxygen simultaneously with high pCO2 levels that are progressively increasing as a result of rising atmospheric CO2. These multiple stressors could potentially impact the growth and calcification of economically valuable molluscs, such as
