Come Down and Explore the Deep Ocean of Adventure

There is so much to explore in the ocean, sea creatures, deep dark areas of the ocean and so much more.

Oceans cover about 70% of the Earth's surface. The oceans contain roughly 97% of the Earth's water supply.

The oceans of Earth are unique in our Solar System. No other planet in our Solar System has liquid water (although recent finds on Mars indicate that Mars may have had some liquid water in the recent past). Life on Earth originated in the seas, and the oceans continue to be home to an incredibly diverse web of life.

The oceans of Earth serve many functions, especially affecting the weather and temperature. They moderate the Earth's temperature by absorbing incoming solar radiation (stored as heat energy). The always-moving ocean currents distribute this heat energy around the globe. This heats the land and air during winter and cools it during summer.

THE OCEANS

The Earth's oceans are all connected to one another. Until the year 2000, there were four recognized oceans: the Pacific, Atlantic, Indian, and Arctic. In the Spring of 2000, the International Hydrographic Organization delimited a new ocean, the Southern Ocean (it surrounds Antarctica and extends to 60 degrees latitude).

There are also many seas (smaller branches of an ocean); seas are often partly enclosed by land. The largest seas are the South China Sea, the Caribbean Sea, and the Mediterranean Sea.



Dead oceans, dead planet

We need to defend them now more than ever, because the oceans need all the resilience they can muster in the face of climate change and the potentially disasterous impacts this is already beginning to produce in the marine world. The Greenpeace Defending our Oceans campaign sets out to protect and preserve our oceans now and for the future by setting aside swathes of the global oceans from exploitation and controllable human pressure, allowing these areas the respite they so desperately need for recovery and renewal.

Building on a protection and recovery system established to manage land based over-exploitation, Marine Reserves are the ocean equivalent of national parks. Marine Reserves are a scientifically developed and endorsed approach to redressing the crisis in our oceans which work alongside a range of other measures designed to ensure that the demands we make of our oceans are managed sustainably. Beyond Marine Reserves we need to tackle a great many threats to the oceans' viability and find better ways of managing their resources. To this end, while Greenpeace campaigns for Marine Reserves, we also campaign against the acts which have brought the oceans to this point - we expose the countless pressures, reveal the threats, confront the villains and point to the solutions and measures necessary to create sustainable oceans.
