Sea-Level Rise, El Niño, and Storm Effects on Coastal Tidal Marshes

Tidal marshes exist as a transitional environment between the land and sea, and provides habitat to fish and wildlife, protects human developments from coastal flooding, and stores carbon at high density, among other important ecosystem services. Over the next century, accelerating sea-level rise poses a risk to tidal marshes, especially in areas with insufficient sediment
