Don't be Salty
Breathe Deep
Potentially Hydrogen

Not really on the test but kind of helpful maybe?
100
The salinity of the ocean
What is 3.5% (35ppt)
100
DO Stands for this
What is dissolved oxygen?
100
pH is a measurement of this factor in water
Acidity/Basicity
100
The two elements that in high quantities can cause eutrophication
N and P
100
You are basic.
No seriously.
Explain why.
Blood pH is 7.4ish (7.35-7.45)
200
How salt gets into the ocean
What is erosion from rivers
200
DO enters the ocean this way
Mixing of water
Photosynthesis
200
Neutral pH is represented by the number
7
200
Two molecules that make up the nitrogen cycle
N2, NH4, NO2,NO3
200
How salty does water have to be for it to be salty to you?
0.9%
300
How salinity affects buoyancy of objects
What is Saltier = they float higher
300
DO is highest in areas that have these three factors
Cold water
High sunlight
Heavy mixing of water
300
The two molecules that combine to form Carbonic Acid
CO2 + H2O
300
This is when ammonification happens
Organisms die or produce waste
300
In the 1999 film The Phantom Menace, Obi Wan Kenobi wears this A99 breathing apparatus to breathe under water. Describe what this device must do to be sufficient
It has to dramatically increase the oxygen in the water (by processing it quickly or something) because water has WAY less oxygen! (1-12 -> 200)
400
Two factors that increase salinity
Two factors that decrease salinity
Increase: Evaporation, Depth (Deeper is saltier), Temperature (Colder)
Decrease: Precipitation, Shallower, Warmer water
400
The level of DO expected in the air we breathe
and
the level expected in seawater
air: 200 ppm
water: 1-12ppm
400
Low pH levels can harm animals in this way
Dissolving their shells/bones
400
Excessive nitrates cause what to happen
Plants/Algae growth
400
The saltiest place on Earth
Don Juan pond, Antarctica!
44% salinity! (It never rains)
500
How salt is handled by specific organisms (pick one and describe it)
Many organisms use their kidneys, sharks have a specialized gland, plants have salt glands
Clams and oysters can open and close their shells to moderate water content
500
This happens to organisms when DO levels rise too high to extreme levels in ocean water.
gas bubble disease! Kills fish
Invertebrates seem to not care, though!
500
The reason the ocean is basic
Calcium carbonate is a basic buffer (8.5)
500
The cause of mass deaths as the result of dead zones
Algae death -> blocks sun -> no oxygen -> death!
500
Low DO? Bad for fish. Bad for humans too!
This is what low blood oxygen as a disorder is called
What is Hypoxemia
