The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions.It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on the definition, to Antarctica) in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
It has three separate dorsal fins, and the catfish-like whiskers on its lower jaw.In appearance, it is similar to the Atlantic cod.A bottom dweller, it is found mainly along the continental shelf and upper slopes with a range around the rim of the North Pacific Ocean, from the Yellow Sea to the Bering Strait, along the Aleutian Islands, and south to about Los Angeles, down to depths of 900 m ...
The Indian Ocean joins the Pacific Ocean to the east, near Australia. The Arctic Ocean is the smallest of the five. It joins the Atlantic Ocean near Greenland and Iceland and joins the Pacific Ocean at the Bering Strait. It overlies the North Pole, touching North America in the Western Hemisphere and Scandinavia and Siberia in the Eastern ...
The Pacific is ringed by many volcanoes and oceanic trenches. The Pacific Ocean evolved in the Mesozoic from the Panthalassic Ocean, which had formed when Rodinia rifted apart around 750 Ma. The first ocean floor which is part of the current Pacific plate began 160 Ma to the west of the central Pacific and subsequently developed into the ...

Red pencil urchin – Papahānaumokuākea. The Papahānaumokuākea Marine National Monument (PMNM) (roughly / p ɑː p ɑː ˈ h ɑː n aʊ m oʊ k u ˌ ɑː k eɪ. ə / [2]) is a World Heritage listed U.S. national monument encompassing 583,000 square miles (1,510,000 km 2) of ocean waters, including ten islands and atolls of the Northwestern Hawaiian Islands.
The sheets were revealed by sonar, officials say.
A recent study in the journal Climatic Change suggests the expanded reserve could make pelagic fish populations in the Pacific more resilient to ocean warming. [14] Researchers found that by 2060, warmer temperatures will attract skipjack tuna from the Western Pacific to the protected waters of the monument, away from areas that are heavily ...
