In a few words, why is the ocean environment important?
Biodiversity: The variety of plant and animal life in a particular habitat or ecosystem. Ecosystem: A system formed by the interaction of a community of organisms with their environment. Conservation: The preservation and careful management of the environment and natural resources.
Pelagic zone - the water column where swimming and floating organisms live. Benthic zone – Refers to the bottom part of the ocean. The organisms that lives on the benthic zone are called benthos.
Zone of the ocean based on the marine life
is a fissure on the seabed from which geothermally heated water discharges.
are organisms that make their own energy with the use of chemicals and that process is called "CHEMOSYNTHESIS".
shallow marine environment extending from mean low water down to 200-metre (660-foot) depths, generally corresponding to the continental shelf. There is where you see the corals and coral reefs.
High Tide- when water advances to its furthest extent onto the shoreline. Low Tide- the time when the sea has reached its lowest level.
Types of tides
Remote operated vessels (ROV)- highly maneuverable underwater machines that can be used to explore ocean depths while being operated by someone at the water surface. Pilot vessels - type of boat used to transport maritime pilots between land and the inbound or outbound ships that they are piloting.
Types of vessels
Sonar is a technique that uses sound propagation to navigate, measure distances, communicate with or detect objects on or under the surface of the water.
contains deep trenches, volcanoes, and ocean basins.
What are the factors that causes to have ocean current?
What are the differences of upwelling and downwelling based on the picture?
underwater ecosystems formed in shallow water by the dense growth of several different species known as kelps. Photosynthesis
What are the most important steps we can take to protect our ocean environment?
- Developing renewable energy sources
- Reducing plastic consumption
- Improving waste management infrastructure
- Cleaning up oil spills
Over 80 percent of life on Earth is found in the ocean! Covering about 70 percent of our planet, the ocean holds about 97 percent of Earth's water supply! The deepest part of ocean is located in the Mariana Trench. This reaches a depth of about 11 kilometers (6.8 miles)!!
