Introduction

Surface view of the Atlantic Ocean

The ocean is the body of salt water that covers approximately 70.8% of Earth. In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. The following names describe 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 Earth's hydrosphere and is thereby 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...)

A sea is a large body of salt water. There are particular seas and the sea. The sea commonly refers to the ocean, the interconnected body of seawaters that spans most of Earth. Particular seas are either 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, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology. (Full article...)

Marine art or maritime art is a form of figurative art (that is, painting, drawing, printmaking and sculpture) that portrays or draws its main inspiration from the sea. Maritime painting is a genre that depicts ships and the sea—a genre particularly strong from the 17th to 19th centuries. In practice the term often covers art showing shipping on rivers and estuaries, beach scenes and all art showing boats, without any rigid distinction – for practical reasons subjects that can be drawn or painted from dry land in fact feature strongly in the genre. Strictly speaking "maritime art" should always include some element of human seafaring, whereas "marine art" would also include pure seascapes with no human element, though this distinction may not be observed in practice. Ships and boats have been included in art from almost the earliest times, but marine art only began to become a distinct genre, with specialized artists, towards the end of the Middle Ages, mostly in the form of the "ship portrait" a type of work that is still popular and concentrates on depicting a single vessel. As landscape art emerged during the Renaissance, what might be called the marine landscape became a more important element in works, but pure seascapes were rare until later. (Full article...)
