A conceptual diagram illustrates the current issues that bay subtidal and mudflat habitats face as well as the problems they are likely to face in the future as climate change impacts this ecosystem. — Effects of Climate Change on the Bay Subtidal and…

In the section of the river above the dam builds up with sediment, making the dam shallower. High water flow causes scouring and the transport of sediment and associated nutrients over the dam. On this other side of the dam phosphorus mobilizes in reaction with salt water. Further down the river seagrass beds grow on the Susquehanna flats. — Conowingo Dam Reservoir and Susquehanna Flats…
