1 Ocean Movements

2 Wave: A rhythmic movement in which energy is carried through water.

3 Wave Height is determined by: Wind speed Wind speed Wind duration Wind duration Fetch Fetch The amount of water that wind blows across The amount of water that wind blows across

4 Breakers: Crest out running the trough of the wave Friction slows the bottom of the wave as it comes in to shore

5 Tides The rise and fall of sea level Huge waves

6 Spring Tides and Neap Tides

7 Bay of Fundy Highest high tides in the world

8 Location: North of New York

10 Bay of Fundy – Reversing Falls

11 Reversing Falls

12 Power from ocean movement

14 Density Currents or Thermohaline Circulation

15 Density Currents

16 Thermohaline Circulation

17 Wind Patterns

18 Surface Currents (Winds)

19 Gyres Ocean currents are influenced by the continental masses around the three oceanic basins. Continents cause these currents to develop a circular pattern.

21 El Niño Spanish for child (comes around Christmas time) Spanish for child (comes around Christmas time) Causes droughts in places that usually have rain Causes droughts in places that usually have rain Causes floods in places that are usually dry Causes floods in places that are usually dry Starves ocean life by discontinuing upwellings Starves ocean life by discontinuing upwellings Happens every 2 – 7 years Happens every 2 – 7 years

22 Upwelling: Upward movement of ocean water Driven by winds pushing against surface water Cold deep water is pulled up off the ocean floor Nutrient rich – this feeds ocean life

That's good news, as those of us who live in hurricane vulnerable areas well know.

27 El NiñoEl Niño, an abnormal warming of the Eastern Pacific Ocean, suppresses tropical storm formation – and theres still more than a month to go before the end of hurricane season. As winter sets inAs winter sets in, a strengthening El Niño might not be great news for the Southeast, as it is expected to produce wetter and colder conditions than normal. As we reported earlier, it also could spawn severe weather, including tornadoes. The National Weather Service in Miami will hold a press conference today to expound on that.reported earlier In the meantime, Im guessing most are grateful to El Niño for the quiet storm season thus far.
