How Tuesday Webinar: Coastal and Ocean Acidification Data

MARCH 19, 2024 12-1PM

REGISTER HERE

Join us March 19 at noon for a guided tour of the Portal’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.

This latest edition of the Portal’s “How Tuesday” webinar series will feature a presentation by Carly LaRoche, a Ph.D. candidate at the University of Virginia in the Department of Environmental Sciences.
