Questioning 'what is the average salinity in an estuary?' is the wrong question! An estuary is formed where a river meets the sea, the sea would be typically around 35,000 mg/L (total dissolved salts) and the river may be very fresh, say 100 mg/L or possibly brackish if it has picked up salt along the way. That may depend on the river flow rate and salt accessions within the river basin. The salinity of the estuary will range from sea salinity to fresh along the length of the estuary depending upon tidal interchange and river flow rates. A more important question, particularly for the ecology, is what is the transient range at any point and how might this vary depending upon seasons and drought cycles. This will affect the range of ecologic systems (flora and fauna) that can thrive or survive. Some systems need only fresh water others need only salt water, however the estuary offers the opportunity for fish and other species which enjoy different salinity at different parts of their life cycle.

Would salinity increase or decrease in an estuary during spring floods?
When the river brings in extra water, such as during periods of flooding, the salinity, or the amount of salt, in the water of the bay will be reduced.
Which biome has a salinity of .005 or less?
Freshwater has a salinity of .005 percent or less.
What are some abiotic and biotic factors for the Estuary Biome?
What are some Abiotic and Biotic things in estuary ecosystem
What ecosystem has the highest level of salinity?
The marine ecosystem has highest level of salinity.
How does salinity happen?
Salinity is the saltiness or dissolved salt content of a body of water. Salinity in Australian English and North American English may also refer to the salt in soil.
What best describes the change in salinity in an estuary at low tide?
Salinity falls as the out flowing tide brings in more fresh river water.
How do you protect an estuary?
Clean up pollution, insure that the salinity is not disrupted unnaturally, and prohibit overfishing.
What man-made or natural event can decrease the salinity of the estuary area?
Global warming,desalination... :)
What is the average temperature of a estuary?
The average temperature of an estuary ecosystem is not valid because an Estuary is an extremely fertile area where a river meets an ocean. The average temperature in a estuary varies greatly because of the shallow water. The temperature of an estuary usually depends on the location and season.
Would salinity increase or decrease in an estuary during spring floods?
When the river brings in extra water, such as during periods of flooding, the salinity, or the amount of salt, in the water of the bay will be reduced.
Marine organisms that are well adapted to drastic changes in salinity would most likely be found in which environment?
That would be Estuary.
What is the average salinity in the oceans?
The average salinity of seawater is 35 parts per thousand (or ppt).
What is the average of salinity?
The average salinity of seawater is about 35 parts per thousand
What is the average salinity in water?
1000ppm
How salty are estuaries?
Salinity varies within the estuary and depend on other factors such as tides. Estuaries are essentially where freshwater from rivers, streams, etc, meet with saltwater from the ocean. The range of salinity within an estuary is typically between 0-25ppt, and that is between where the mouth of the river ends on to where the ocean begins. PPT stand for parts per thousand, just in case you did not know.
What is a salinity?
Salinity usually refers to the percentage of dissolved salt in water. A salinity meter simply measures this. 3.5% salinity = 35g of salt/Litre (this is your average salt water)
What is the salinity of the Great Salt Lake?
The salinity of the Great Salt Lake varies, but is on average about 12%.
