Aragonite Undersaturation in the Arctic Ocean: Effects of Ocean Acidification and Sea Ice Melt
Acidic Ocean One consequence of the historically unprecedented level of CO 2 in the atmosphere that fossil fuel burning has caused, in addition to a warmer climate, is higher concentrations of dissolved CO 2 in the oceans. This dissolved CO 2 makes the oceans more acidic, and thus less saturated wit...
