The March 19 edition of the Mid-Atlantic Ocean Data Portal's "How Tuesday" webinar series provided a tour of the site’s coastal and ocean acidification monitoring sites maps and an overview of acidification in the Mid-Atlantic.

A collection of seven acidification-related maps in the Portal’s Water Quality theme were recently expanded to include 20,000 additional sites where sampling is currently being or has been conducted recently in the region. Taken together, the maps serve as a valuable tool for the Mid-Atlantic Coastal Acidification Network (MACAN) in its goal to develop a robust network that monitors for changes to the region’s water chemistry.
