What are characteristics of coastal waters?
Such coastal phenomena and features include waves, tides, circulation cells, currents, fronts, eddies, stratification, water masses, ice formation, turbulence, and mixing. All occur with varied strength in the diverse coastal ocean regions.
What is happening to the quality of coastal waters?
The severity and extent of nutrient pollution are expected to worsen in more than half of the nation’s estuaries and coastal waters by 2020. 4 Without concerted, coordinated, and sustained action to reduce nitrogen sources, nutrient pollution will be a continuing problem in the nation’s coastal waters.
Why is coastal water quality important?
Water quality is one of the most important components of a healthy ecosystem. Clean water provides a drinking supply for communities, supports a diversity of plants and wildlife, and enhances recreation and tourism.
What are the 3 water quality?
There are three types of water quality parameters physical, chemical, and biological [8, 9].
What are considered coastal waters?
Coastal waters are those parts of the ocean closest to the land. They start where the breakers hit the beach and then stretch seaward as far as 100 nautical miles (approximately 115 miles or 185 km). Any bays, inlets, coves, harbors or sounds in this range are also considered part of the coastal waters.
Are coastal waters freshwater?
Coastal waters are transition areas where freshwater and marine water come together. Inland, freshwater streams and rivers flow toward the shorelines and empty into the ocean. This creates transitional areas that include marshes, swamps, estuaries, tidal pools, beaches, and inlets.
Why is water quality important?
Poor water quality has its most direct impact on aquatic wildlife, particularly fish, bugs, and plants. Excess nutrients, sediment, road salt, and other contaminants can reduce the variety and hardiness of organisms living in the state’s waters.
How can water quality be improved?

What is good quality water?
In one gallon of water, one grain of hardness translates to 64.8 milligrams of calcium or 17 ppm present. Less than one grain per gallon is considered “soft” water, more than 7 grains per gallon (gpg) is considered “hard” water. Most people enjoy drinking water at approximately 4 grains of hardness.
What are 5 water quality indicators?
They include dissolved oxygen, pH, temperature, salinity and nutrients (nitrogen and phosphorus).
Is coastal water freshwater?
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean. Estuaries, and their surrounding lands, are places of transition from land to sea.
How deep are coastal waters?
Coastal Ocean The sliver of ocean less than 200 meters (650 feet) deep near land accounts for just 7 percent of the sea surface, but is among the most productive parts of the ocean.
