Different types of estuaries & the zones of an Estuary Depending on the amount of influence from freshwater and marine inputs and the circulation of water, different estuaries are divided up into different categories. For example, along the Great Lakes, river water with very different chemical and physical characteristics mixes with lake water in coastal wetlands that are affected by tides and storms just like estuaries along the oceanic coasts. These freshwater estuaries also provide many of the ecosystem services and functions that brackish estuaries do, such as serving as natural filters for runoff and providing nursery grounds for many species of birds, fish, and other animals. Wetlands are broadly defined as an area of land saturated with water. Mostly the species of the neighbouring ecosystem are found in the Estuary marine ecosystem. It is usually expressed in parts per thousand (ppt), or the number of grams of dissolved salts present in 1,000 grams of water.

The interactions between human impacts and natural changes in the ecosystem include the aspects of bio-diversity and global change. Which of the following would disappear first if an estuary was destroyed? What are the characteristics of an estuary ecosystem. Also called lentic environments, they are masses or bodies of water that are in a closed space that always remains stagnant, that is, in the same place, without flowing to any side. Sea water is 20-35 parts per thousand. Chuwen, S.D. the video instead. Each estuary is unique with respect to physical, chemical, and biological characteristics, but estuaries share many common features. Some biomes include rainforests, tundra, deserts, taiga, wetlands, rivers and oceans. These features include the physical, biological and chemical aspects of a specific habitat. Ecol. The waters are brackish and have some of the same characteristics of each biome. Estuaries can experience fairly extreme changes in abiotic conditions. Estuaries have water that is saltier than the water found in or The speed at which photosynthetic organisms produce organic matter in an ecosystem. Here's a direct link to Some characteristics.
