The following presentation was shared with us by our friends in the Alaska National Parks. Since every one of our national parks in the Pacific Islands are coastal parks, ocean acidification is a very real concern as we move further along into the 21st Century. This presentation was given by Dr. Jeremy Mathis of NOAA’s Pacific Marine Environmental Laboratory and was recorded on February 28, 2013. We hope you learn a lot about this very relevant issue to out parks and to our world. Aloha.
