Arctic Ocean Acidification: Some Key Findings
Key finding 1Arctic marine waters are experiencing widespread and rapid ocean acidification
Key finding 2The primary driver of ocean acidification is uptake of carbon dioxide emitted to the atmosphere by human activities
Key finding 3The Arctic Ocean is especially vulnerable to ocean acidification
Key finding 4Acidification is not uniform across the Arctic Ocean
Average global surface ocean pH has fallen from a pre-industrial value of 8.21 to 8.10, (a 28.8% increase in acidity). Values of 7.8–7.9 are expected by 2100.

Challenges Opportunities
Arctic residents
Losers?
Diminishing traditional food resources, insecure travel on ice
Employments
The globalcommunity/multi-nationalindustry
Winners?
Sea level rise; amplified warming; ocean acidification
Better access (to oil and gas, mining, fisheries); new shipping routes
Challenges and Opportunities: Winners and Losers

Recommendations
Gaps: • Interactions between the Atlantic and the Arctic - the
biological & chemical interaction with the physical processes• Feedbacks from the Arctic on the Atlantic, & on the
hydrological and climate system
Filling gaps: • Joint integrated programmes between Europe and North
America – research, monitoring & assessments• More stations/platforms within the Arctic (SAON)• Stimulate free access to data and information (SAON)
