Marine Protected Areas

     Marine Protected Areas
  • The main aim of a marine reserve is to create an area largely free of human impacts, providing a useful comparison for scientists to study.
  • Marine Management bill was drafted for the protection and sustainable use of the Kaikoura marine environment.
  • The marine reserves of Fiordland are grouped together in an overarching. The Marine reserves act was passed in 1971.
  • Marine reserves may be established in areas that contain underwater scenery. Marine reserves currently provide the highest level of marine protection
  • These prevent all marine-based activities that may threaten undersea cables or pipelines.

How Waves Are Made

How Waves Are Made
  • Waves are mainly a product of the wind. The best waves for surfing are the result of the interaction of winds on the surface of the ocean, far away from the coast. Wind is the first step in the formation of surfable waves.
  • Local shore winds can also produce waves, but they can also destroy the quality of the breaking waves. Onshore winds are typically known for creating choppy and bumpy waves because their effect is added to the direction of the wave.
  • In a way, offshore winds are a sort of a counterbalance. Swell comes from miles away and the ground wind works as a "pause-hold" effect on the wave face, allowing longer unbreakable waves.In theory, low pressure systems are responsible for creating good and strong waves.
  • In deep low pressure systems, wind speed is greater and more waves are generated by the power of the gusts.

How is a wave formed: wind is the source of the surf
