Oceanography

Wave height

top of crest to bottom of adjacent trough

Frequency

the number of complete wavelengths that pass a point in a given time; speed x wavelength

Wavelength

The distance between two corresponding parts of a wave

Water depth

calculates speed of waves

Tsunami speed equation

Normal conditions

Winds move water from eastern part to the western Pacific Ocean; driven west

El Nino

Warm water driven east by strong counter currents

Surface

Driven by wind and global patterns

Deep

Density and temp. differences in the ocean

Important for marine ecosystems

Diurnal

occur once daily

semidiurnal

occur twice daily and also equal height

Mixed semi-diurnal

occur twice and unequal height

High tide

The lower of 2 high tides

Higher High Tide

The higher of 2 high tides

Low tide

Higher of 2 low tides

Lower low tide

Lower of 2 low tides

Neap Tides

First and third quarter; Smallest tide ranges

Spring Tides

Full and New Moon; Highest tide ranges

Stages of the moon do not tell us whether itd be higher or lower tide;

Which tell us what the tidal range would be

Estuary

Partially enclosed coastal water body freshwater + salt water

Where rives meet the sea

Despositional

Prevents pollution

Mud flats

silt mud brought in by sea and ocean

Salt Marsh

Near spits

Absorbs majority of water hitting the coast line

Mangrove Forest

Tropics/subtropics

Acts as a barrier between tides and coast lines

roots being exposed during low tides

Depositional

Erosional

Fossil fuel being burned increases the amount of carbon dioxide that is trapped in the atmosphere,

increases the temperature

74 mph

To become a hurricane

130

Under 5 cateagory hurricane

Twilight

3% down in the ocean

90% of animals use Bioluminescence Chemicals

Midnight

Species are energy deficient

harder to take a swim than walk in space

Abyssal Plain

Grey mud and rocks

Manganese nodules

400C jets

Hadal Zone

Underworld of the sea

Long narrow trenches
