How many oceans are there?
While there is only one global ocean, the vast body of water that covers 71 percent of the Earth is geographically divided into distinct named regions. The boundaries between these regions have evolved over time for a variety of historical, cultural, geographical, and scientific reasons. Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean. The Pacific, Atlantic, and Indian are known as the three major oceans. The Southern Ocean is the 'newest' named ocean.

Marine Conservation Organizations
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. We list them here both as a public service and to spread the word. Please Contact us if you have any comments, changes, or suggestions. » Invitation to fellow marine conservation groups For an objective annotated list of the organizations listed below and others, visit Mother Jones magazine's guide to environmental organizations The oceans are downstream of everything.

Quick Facts on Icebergs | National Snow and Ice Data Center
Icebergs are commonly found near Antarctica and in the North Atlantic Ocean near Greenland. What is an iceberg? Icebergs are pieces of ice that formed on land and float in an ocean or lake. Icebergs come in all shapes and sizes, from ice-cube-sized chunks to ice islands the size of a small country. The term "iceberg" refers to chunks of ice larger than 5 meters (16 feet) across. How do icebergs form, and where do they go? Icebergs form when chunks of ice calve, or break off, from glaciers, ice shelves, or a larger iceberg. When an iceberg reaches warm waters, the new climate attacks it from all sides. Icebergs can develop into a variety of shapes as they break apart. Why are icebergs important? Icebergs pose a danger to ships traversing the North Atlantic and the waters around Antarctica. The International Ice Patrol uses airplanes and radars to track icebergs that float into major shipping lanes. Scientists test their equipment on a small iceberg during the 2006 IceTrek expedition.
Marine biology
Only 29 percent of the world surface is land. The rest is ocean, home to the marine lifeforms. The oceans average nearly four kilometres in depth and are fringed with coastlines that run for 360,000 kilometres.[1][2] A large proportion of all life on Earth exists in the ocean. Exactly how large the proportion is unknown, since many ocean species are still to be discovered. Marine life is a vast resource, providing food, medicine, and raw materials, in addition to helping to support recreation and tourism all over the world. Many species are economically important to humans, including food fish (both finfish and shellfish). History[edit] The observations made in the first studies of marine biology fueled the age of discovery and exploration that followed. The creation of marine labs was important because marine scientists had places to conduct research and process their specimens from expeditions.

Volcanoes (Volcanoes are not associated with weather, but instead are natural disasters.) What is a volcano?A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Click Here to learn more about volcanoes from USGS. How are volcanoes formed? What are plate tectonics?

Seahorses, Seahorse Pictures, Seahorse Facts
Seahorses are truly unique, and not just because of their unusual equine shape. Unlike most other fish, they are monogamous and mate for life. Rarer still, they are among the only animal species on Earth in which the male bears the unborn young. Found in shallow tropical and temperate waters throughout the world, these upright-swimming relatives of the pipefish can range in size from 0.6 inches (1.5 centimeters) to 14 inches (35 centimeters) long. Male seahorses are equipped with a brood pouch on their ventral, or front-facing, side. When mating, the female deposits her eggs into his pouch, and the male fertilizes them internally. Because of their body shape, seahorses are rather inept swimmers and can easily die of exhaustion when caught in storm-roiled seas. They anchor themselves with their prehensile tails to sea grasses and corals, using their elongated snouts to suck in plankton and small crustaceans that drift by.
