Episode notes
Coastal Currents
- Coastal currents are driven by wave action, primarily caused by wind.
- When waves break at an angle to the shore, they create longshore currents that move sediment and water.
Rip Currents
- Rip currents form when waves encounter obstructions like sandbars, creating a narrow channel for water to flow back out to sea.
- This can create a suction effect, posing a danger to swimmers.
Upwelling
- Upwelling occurs when wind pushes surface water away from an area, causing deeper water to rise and replace it.
- This process plays a crucial role in nutrient cycling and oxygen distribution in the ocean.
