Tides (Group Presentation)
For the Tide-part of this section, I decided to include my group presentation. I mainly had a hand in finding sources for the basics of tides and how they work, but my assigned part was the pollution of tides.
My team members for this presentaion were Carynn, Raul, and Damon. Feel free to also take a look at this Kahoot I made myself.
Coasts
Coasts, define simply, are just the areas of land where the ocean shallows and stops. Coastlines are where waves are experienced, and where most of our beaches are located. We refer to the edges of the U.S., or turtle island, as the east coast and west coast.
70% of our coasts are erosional, which means they are constantly depleting. The variation of the land around our coasts are due to sand input and output, which determines how flat or raised a beach is. World-renowned oceanography professor Jamey Cooper, there are coastal cells where sand input and output are equal, and uses the example of Redondo beach. Coastal cells contains a complete cycle of sedimentation( transport paths, sinks, etc) and provides the perfect framework for the quantitative analysis of coastal erosion.(CIRIA)
Waves
Waves are causes by enery moving through the ocean, creating circular-like motions (NOAA)
While most waves are caused by wind currents alone(usually most waves we see are caused by the friction of the wind and the water), there are tidal waves, caused by gravitational pull of the sun and moon on the ocean. Tidal waves are also called tides.
There are mixed tides, which are a mixture of tidal waves(astronomical positioning) and amphidromic circulation, where waves surround a specific point in the ocean (like an ocean basin). Amphidromic points usually stay flat, because of the cancellation of all of these waves meeting eachother.
The National Oceanic and Atmospheric Administration, or NOAA, define these occurences as "the life force of our world ocean."
