AMAP assessment 2013 : Arctic ocean acidification

Disclaimer: The views expressed in this peer-reviewed report are the responsibility of the authors of the report and do not necessarily reflect the views of the Arctic Council, its members or its observers. [...] The functioning of the Arctic Ocean in the context of acidification. [...] Thus, a ten-fold change concentration since 1860 (see right-hand part of graphic for in the hydrogen ion concentration results in a pH change the percentage change in ocean acidity relative to a starting of 1. The solution is said to be acidic if the pH is below 7, point of pH 8.2 – the value at the start of the industrial era). [...] In Nunavut, Canada about 90% amounts of methane hydrates stored in sediments along the of the population is Inuit; Inuit also make up most of the continental margins, releasing methane (CH ) into the water 4 population of Greenland, whereas the Saami account for only column and possibly the atmosphere, with the Arctic particularly about 2.5% of the population in northern Scandinavia. [...] Accordingly, processes over the shelves are The objectives of the present assessment are to provide the extremely important to the functioning of this ocean, and these Arctic Council with timely, up-to-date, and synthesized regions are also most important to the inhabitants of the Arctic scientific knowledge about the present status, processes, in terms of travel and access to food.
