Seawater Properties
Name at least three properties of seawater...
Temperature, Salinity, Pressure, Density, pH, Nutrient Levels
Ocean circulation impacts temperature and what else?
Climate
Thermohaline circulation means what?
Thermo - Temperature
Haline - Salinity
Wind Wave
generated by the surface winds
One high and one low tide per day
Diurnal
Temperature decreases rapidly with depth. What is the word that is used for this transitional layer between the warmer surface water and the colder deep water below?
Thermocline
Surface circulation is mainly driven by the ______.
Wind
Thermohaline circulation forms currents in what layer of the ocean?
Deep
Tsunamis
caused by undersea earthquakes or landslides
Two highs, two lows of sililar size
Semidiurnal
Salinity of the ocean is impacted by four main things... what are they?
Evaporation, Precipitation, River inflow, Ice formation & melting
What causes the Coriolis Effect?
The Earth's Rotation
Thermohaline circulation drives the Global Conveyor Belt. How long does it take for water to fully circulate in one cycle on this "conveyor belt"?
about 1000 years
Storm Surge
abnormal rise due to storm winds
two highs, two lows of different sizes
Mixed
Pycnocline refers to what?
The layer of water where density rapidly increases with depth. (Similar to the thermocline for temperature.)
Surface convergence means what?
The water converges... comes together and creates downwelling
Large water masses within the ocean have distinct temperature, density, or _____________?
Salinity
Capillary Waves
also known as ripple waves, caused by the disturbance of the surface of a fluid due to the effects of gravity and surface tension
What are the two types of tides?
Spring Tide and Neap Tide
Temperature and Salinity play a major role in what?
Density
Surface divergence means what?
The water spreads and upwelling occurs
The boundaries between water masses are referred to as __________________.
Ocean Fronts
Rouge Wave
a wave whose height is more than twice the significant wave height (the mean of the largest third of waves in the wave record)
What causes tides?
Gravitational pull
