2025年1月15日 · Estuaries are partially enclosed, coastal water bodies where freshwater from rivers and streams mixes with salt water from the ocean. The United State’s largest estuary is the Chesapeake Bay along the mid-Atlantic coast. These transitional zones are among the most nutrient-rich and productive natural habitats in the world.

2024年12月18日 · Maintaining species richness in the biosphere ensures the productivity and stability of ecosystem processes, making it critical to monitor vegetation and wildlife health and prevent their loss. There are many human causes of biodiversity loss on Earth, including deforestation, agricultural development, urbanization, water and air pollution, and ...

dammed an epishelf lake, a body of freshwater that floats on denser ocean water. This epishelf lake, located in Disraeli Fiord, was host to a rare ecosystem, and it was the largest and best-understood epishelf lake in the Northern Hemisphere. When the Ward Hunt Ice Shelf fractured, the epishelf lake suddenly drained out of
