Only 29 percent of the world surface is land. The rest is ocean, home to the marine lifeforms. The oceans average four kilometers in depth and are fringed with coastlines that run for nearly 380,000 kilometres.
This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites to measure physical oceanography parameters such as ocean currents, ocean winds, sea surface height and sea surface temperature.
MarineBio is deeply committed to marine conservation and founded on the concept that, by sharing the wonders of the ocean and marine life, people will be inspired to protect it. We hope you will consider becoming a MarineBio Conservation Society member to help us bring the ocean and the conservation message to as many people as possible. There are many other organizations working on marine conservation and other environmental issues such as biodiversity and global warming.
