What is a wave
transfering energy from one place to another
what generates a water wave?
wind
surface tension
how much the molecules like to stick together
does water have a high or low surface tension and why?
high because of hydrogen bonding
How high was the highest wave ever and where was it
120 ft in Japan
How do water molecules in a wave move?
they circle back to their original position
Where is the energy of a wave from? (answer is not wind)
miles and miles away, it travels
what is wave steepness?
wave h/wave l
whats is wave period
time it takes for 1 wave length T (sec)
What 3 things does a wave need in order to be huge
wind velocity (faster = higher) wind duration (longer = higher fetch (size of the body of water)
How much does water depth come into play in determining if a wave will be high or not
its insignificant
deep water wave
when a wave isnt as tall as the depth of water and the bottom isnt effected at all
short waves have fast or slow speeds?
slow
long waves have fast or slow speeds?
fast
high friction = fast or slow waters?
slow
low friction = fast or slow waters?
fast
Where in a body of water has high friction?
by the shore because it hits the bottom because its coming to land.
high friction = high or low waves
high
low friction = high or low waves
low waves
whats the idea of stacking waves?
when a wave comes to shore it slows down and since the waves farther from shore still come in they stack making higher but slower waves
H or L Velocity= H or L length= H or L height= High or low steepness
Low Velocity= Low length= High height= High Steepness

or
High Velocity = High length = Low Height = Low Steepness
At what point of steepness do waves break?
1/7
Where was the huge earthquake and why did it happen?
Indonesia, indian ocean. The lower density plate was attached to high and ended up going under (shouldn't) and when they broke it shot up. It was the equivalent to droping a rock the size of .5 of washington.
whats a rising tide called
flood tide
whats a falling tide called?
ebb tide
whats the tidal wave cycle
24 hr and 50 min
Diurnal tide
only 1 high tide and 1 low tide each day
Semidurnal tide
more than 1 high tide and 1 low tide a day
spring tide
when tidal range is at its maximum
neap tide
when tidal range is at its minimum
what are tides
waves based on gravity not winds
Gravitational force is determined more by mass or distance?
distance
if an object is closer its gravitational pull is higher or lower
higher
Explain the bulges thing
whatever object is fixed (moon) the moving one (earth) has a buldge towards the moon and one away from it.
Which buldge is bigger?
they are the same size
if you are on the buldge where are you
high tide
when is there a chance at diurnal tides?
the moon is at 1,5,7,10 and you are around 65 degrees or -
declination angle
twice a month when its on the equator
if you are at the equator what tides do you get always?
semi diuernal
macrotidal area
huge tidal range
can a tide change from spring to neap quick or does it take a while?
within a month it can drastically change
what happens when the moon is
x earth sun
the pull is the same so high tides are higher and low tides are lower. High tidal range. Constructive wave interference
what happens when moon is
x
earth sun
moons pull and suns pull are different so high tides are low and low tides are higher. Deconstructive wave interference. Low tidal range.
moon
earth
1st quarter
earth
moon
3rd quarter
1st and 3rd quarter are spring or neap
neap destructive
earth moon sun
full moon
moon earth sun
no/new moon
full and new moon are spring or neap
spring constructive
photosynthesis
storing energy from the sun
what do plants need for photosynthesis?
nutrients and sun
what are some nutrients
water chlorophil = sugar and oxygen
What happens in the winter in terms of primary productivity, sunlight, plants, temperature, amount of fish, density upwelling or downwelling
primary productivity decreases, sunlight decreases, less plants, cooler air, less fish, high density water sinks, down welling
Since the winter makes downwelling what happens when it is spring
since water is going down in one area, that means it is going to have to come up later so in the spring waters rise, up welling, tons of plants, and lots of nutrients
Benthic environment
things that attach to the ground (can include crawling)
Pelagic zone
things that float around or swim
Plankton
life forms that are floating
phytoplankton
plants
zooplankton
animals
What is interesting about dinoflagellites
they have a whip like feature that helps them move around
nekton
things that would sink, so they swim
Phyla
Known from Laneus. He's famous for categorizing animals
Where are some places of high production?
Peru, has upwelling high pressure lots of nutrients and extremely biological production
Hypoxic
areas of too much nutrients
where is hypoxic happening
N.O. because of all the crap they get from the mississippi
How does hypoxic happen?
life and plants live in an area where there is too much and then they die and sink to the bottom which turns them into bacteria. After that happens it creates more carbon dioxide. Nutrients need oxygen and since there is CO and plants need oxygen there isn't enough
What is the phytoplankton and trophic pyramid
food chain
What is the highest lvl on the trophic pyramid?
6, top lvl carnivores
what is the 2nd to highest lvl on the trophic pyramid
5, 3rd lvl carnivores
what is the third to highest lvl on the trophic pyramid
4, 2nd lvl carnivores
what is the 3rd to bottom lvl on the trophic pyramid
3, 1st lvl carnivores
what is the 2nd to bottom lvl on the trophic pyramid
2, Herbivorious consumer
what is the lowest lvl on the trophic pyramid?
Primary production plants
What other sense do sharks have that humans don't?
amplory which is being able to detect electric responses
Tiger shark
the sharks that eat the birds when they are learning to fly in shallow water
reef white tip shark
lazy in the day and really active in the night
angel shark
the shark that swallows stuff whole. Camoflauges to the terrain and is really flat with two wings
hammer head
basically eats the bottom of the ocean, eating sang and then filters out the water
gray reef
has the threat position when threatened and then it attacks from the threatened position
mega mouth
rubbery lips, huge shark, feeds on plankton, deep water living
