TT43D:
Submarine, Overland, and Aerial Assault: A Tutorial on Acidification and Carbonate System Variability in Coastal Waters

Session ID#: 85314

Session Description:
Several natural and anthropogenic processes impinge on the coastal zone in ways that either exacerbate or mitigate ocean acidification effects. Within the context of continually increasing atmospheric carbon dioxide, nutrient laden freshwater inputs and strong benthic interactions lead to acid-base reactions that alter the carbonate system. Coastal systems can be highly variable, responding to processes with temporal modes ranging from seconds to centuries. Such variability and proximity to the atmospheric, benthic and oceanic boundaries presents a challenge to marine invertebrates at different life history stages that rely on both benthic and pelagic habitats. This tutorial will review the atmospheric, terrestrial, benthic and oceanic processes leading to the observed variability found in coastal waters, contrast processes occurring on the US East, West, South and North coasts, and discuss the relationships between these processes and the life cycles on commercially-important invertebrates.
