Introduction

The world ocean (sea) is the body of salt water that covers ~70.8% of the Earth. In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. Distinct names are used to identify five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic. The ocean contains 97% of Earth's water and is the primary component of the Earth's hydrosphere, thus the ocean essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir. (Full article...)

The sea normally refers to the Earth's ocean. The term sea may also refer to marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea), or certain large, nearly landlocked bodies of water. (Full article...)

Oceanography (from Ancient Greek ὠκεανός (ōkeanós) 'ocean', and γραφή (graphḗ) 'writing'), also known as oceanology, sea science and ocean science, is the scientific study of the oceans. It is an Earth science, which covers a wide range of topics, including ecosystem dynamics; ocean currents, waves, and geophysical fluid dynamics; plate tectonics and seabed geology; and fluxes of various chemical substances and physical properties within the ocean and across its boundaries. These diverse topics reflect multiple disciplines that oceanographers utilize to glean further knowledge of the world ocean, including astronomy, biology, chemistry, climatology, geography, geology, hydrology, meteorology and physics. Paleoceanography studies the history of the oceans in the geologic past. An oceanographer is a person who studies many matters concerned with oceans, including marine geology, physics, chemistry, and biology. (Full article...)

Wonder of the Seas is the latest ship of Royal Caribbean's Oasis class of cruise ships, largest in service.

Cruise ships are large passenger ships used mainly for vacationing. Unlike ocean liners, they typically embark on round-trip voyages to various ports of call, where passengers may go on tours known as "shore excursions". They may carry thousands of passengers in a single trip, and are some of the largest ships in the world by gross tonnage (GT), bigger than many cargo ships. Cruise ships started to exceed ocean liners in size and capacity in the mid-1990s; before then, few were more than 50,000 GT. In the decades since the size of the largest vessels has more than doubled. There have been nine or more new cruise ships added every year since 2001, most of which are 100,000 GT or greater. In the two decades between 1988 and 2009, the largest cruise ships grew a third longer (268 m to 360 m), almost doubled their widths (32.2 m to 60.5 m), doubled the total passengers (2,744 to 5,400), and tripled in volume (73,000 GT to 225,000 GT). , the largest cruise ship, Wonder of the Seas, has a gross tonnage of 236,857, is 362 metres (1,188 ft) long, 64 metres (210 ft) wide, and holds up to 6,988 passengers.

Cruise ships are organized much like floating hotels, with a complete hospitality staff in addition to the usual ship's crew. They cater to nautical tourists, with recent vessels being described as "balcony-laden floating condominiums". The "megaships" went from a single deck with verandas to all decks with verandas, and feature ameneties such as theaters, fine-dining and chain restaurants, spas, fitness centers, casinos, sports facilities, and even amusement park attractions.

Interesting facts -

Heather Willauer holding samples of synthetic fuel

Heather Willauer (pictured) patented a method for removing carbon dioxide (CO₂) from seawater, in tandem with hydrogen (H₂) removed simultaneously. Willauer has researched catalysts to enable a continuous Fischer–Tropsch process to recombine carbon monoxide (CO) and hydrogen gases into complex hydrocarbon liquids to synthesize jet fuel for Navy and Marine aviation, and fuel for the U.S. Navy's ships at sea.

The sea cucumber Leptopentacta elongata has a U-shaped or S-shaped body and occupies a burrow in the seabed.

The POLYGON experiment, conducted in the 1970s, was the first experiment to establish the existence of so-called "mesoscale eddies", giving rise to the "mesoscale revolution" in oceanography.
