Dissolved Oxygen
what is the measure of how much oxygen is dissolved in water .
Dissolved oxygen
Is density more dense than water?
What is an estuary?
Estuaries are areas of water and shoreline where rivers meet the ocean or another large body of water.
what is theormocline means
a steep temperature gradient in a body of water such as a lake, marked by a layer above and below.
what is a shadow zone
cannot detect direct P waves and/or S waves from an earthquake
what causes dissolved oxygen
Oxygen enters water by direct absorption from the atmosphere, which is enhanced by turbulence
Why is density lower than water?
ice is less denser than water because in ice the molecules arrange themselves in a rigid tetrahedral
What are the 4 types of estuaries?
The four major types of estuaries classified by their geology are drowned river valley, bar-built, tectonic, and fjords.
what dose hyocline means
A relatively sharp discontinuity in ocean salinity at a particular depth.
what is a sofar channel
is a horizontal layer of water in the ocean at which depth the speed of sound is at its minimum
where can disolved oxygen be found
running water , swift moving stream,
what is density
How estuary is formed?
Coastal plain estuaries are created when sea levels rise and fill in an existing river valley.
Why is the thermocline important?
how shawdow zone formed
by the liquid core and P waves being bent (refracted) by the liquid core.
What causes low dissolved oxygen in water?
Low dissolved oxygen (DO) primarily results from excessive algae growth caused by phosphorus.
what is water
What animals live in estuaries?
shore and sea birds, fish, crabs, lobsters, clams, and other shellfish.
What is a halocline in the ocean?
, vertical zone in the oceanic water column
How many shadow zones are there?
there are two different types of shadow zones
Why does cold water have more dissolved oxygen?
The quick answer is that the colder a liquid, the more gas it can dissolve or "contain" as you aptly put it
Is water heavier than density?
Is estuary a freshwater ecosystem?
Estuaries are ecosystems where freshwater from streams and rivers meets.
What is thermocline in a lake?
depth at which the temperature gradient is steepest during the summer
Why is shadow zone important?
Seismic shadow zones have taught us much about the inside of the earth.
