Fast flowing mountain streams have more dissolved oxygen than slow flowing rivers down in the flat valleys. The oxygenation is higher because the tumbling water of the mountain stream increases the area open to absorption.

Bodies of water that are well-oxygenated, usually have higher levels of dissolved oxygen. These include rivers and streams with fast-moving water, as well as colder water bodies like lakes and oceans. Additionally, bodies of water that are heavily influenced by algal blooms or photosynthetic processes tend to have higher dissolved oxygen levels during daylight hours.

What happens if there is too much oxygen in seawater?
Oxygen in the water is called "dissolved oxygen" because quite simply it is just that. The air naturally diffuses into the water and can reach equilibrium with the water. It is virtually impossible to get too much dissolved oxygen in the water because the excess will convert back to gas and bubble out of the water like so much soda water when you pour it out of the bottle. This said, there is no concern for too much dissolved oxygen in the water. Concern arises when dissolved oxygen levels get too low. When this happens more sensitive plants and animals become weak or die. As a side note, weather, temperature, and salinity all effect dissolved oxygen levels. Faster moving water contains more dissolved oxygen because it has more contact with the air than still water. Cold, fresh water holds more oxygen than warm or salty water. This would mean a cold, fast moving, fresh water stream or river would contain the highest amounts of dissolved oxygen, and the salinity of the ocean water would not be ideal for holding as much dissolved oxygen.
What will cause a greater amount of oxygen gas to dissolve in 100 g of water?
High surface area of the water The colder the water the more dissolved oxygen Running water will dissolve more oxygen
What environment has the greater concentration of dissolved oxygen warm water or cool water?
You can't tell just from the temp - cool water is capable of dissolving more oxygen ... but that doesn't mean that it will (or does).
Do oxygen and carbon dioxide readily dissolve in plasma?
no co2 is more readily dissolved in water than oxygen and blood along with plasma is formed of water so co2 is more readily soluble in plasma compared to o2
Where does oxygen come from in Antarctica?
Oxygen is the 3rd most abundant element in the Milky Way Galaxy, and since Antarctica is a continent on earth, it's reasonable that oxygen be available there. As well, cold water holds more dissolved O2 than warmer water.
Biochemical oxygen demand is a measure of?
Biochemical Oxygen Demand is the measure of the amount of oygen consumed by microorganisms in decomposing organic mattter in water bodies. BOD directly affects the amount of dissolved oxygen in water-bodies (i.e. rivers and streams). The greater the BOD, the more rapidly oxygen is depleted in the stream. SOURCE: Google.
Which contain the greater amount of dissolved oxygen a lake in the spring or a lake in the summer?
. Temperature directly affects the solubility of oxygen in water. When the temperature of water increases, a portion of oxygen converts from liquid state to a gas. Thus the ability of water to maintain oxygen in dissolved state decreases with increasing temperature. As a result, colder water can potentially contain more dissolved oxygen than warm water. Therefore, a lake in spring contains greater amount of Dissolved Oxygen than the same lake in summer.
Which one of the following regions would you expect to find the largest amounts of dissolved oxygen in the ocean water?
In the polar regions, there is more dissolved oxygen in the ocean water. The cold water is able to hold more dissolved gases than warm water.
More oxygen sea water than river water?
Oxygen is more soluble in fresh water than it is in sea water, therefore there is more dissolved oxygen in river water than sea water.

Would dissolved oxygen more than likely be in calm water or rapid water?
rapid water
Can a wriggler breathe in dissolved oxygen?
Dissolved oxygen (DO) is the amount of oxygen that is present in the water. Worms, fish, crabs and other underwater animals use gills to get oxygen from the water. Scientists generally agree that the underwater creatures need dissolved oxygen concentrations of 5.0 mg/L or more to live and thrive
Would you expect a fast moving mountain stream or the Mississippi River to have more dissolved oxygen?
I personally would expect the mountain stream to have more dissolved oxygen, because I know that oxygen dissolves better in cold water.
Does a lake or a river contain more dissolved oxygen?
the river would contain more dissolved oxygen because the water movements cause more oxygen to be produced...try looking at lab bench..it's like a prelab but it helps with the basic information
Why is oxygen bad in water?
Cold water can hold more dissolved oxygen than warmer water.
