Biophysical feedbacks mediate carbonate chemistry in coastal ecosystems across spatiotemporal gradients.
Ocean acidification (OA) projections are primarily based on open ocean environments, despite the ecological importance of coastal systems in which carbonate dynamics are fundamentally different. Using temperate tide pools as a natural laboratory, we quantified the relative contribution of community...
