The word Arctic comes from the Greek word ἀρκτικός (arktikos), "near the Bear, northern" [4] and from the word ἄρκτος (arktos), meaning bear. [5] The name refers either to the constellation known as Ursa Major, the "Great Bear", which is prominent in the northern portion of the celestial sphere, or to the constellation Ursa Minor, the "Little Bear", which contains the celestial ...
Sea surface temperature difference between the decades 1960-1970 and 2010-2020 in degrees C. [1] Location of the Barents Sea in the Arctic Ocean. Atlantification is the increasing influence of Atlantic water in the Arctic. Warmer and saltier Atlantic water is extending its reach northward into the Arctic Ocean. [2]
The ocean is the body of salt water that covers approximately 70.8% of Earth. [8] In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. [9] The following names describe five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic.
The borders of the oceans are the limits of Earth's oceanic waters.The definition and number of oceans can vary depending on the adopted criteria. The principal divisions (in descending order of area) of the five oceans are the Pacific Ocean, Atlantic Ocean, Indian Ocean, Southern (Antarctic) Ocean, and Arctic Ocean.
Then, they found a new volcano-like formation deep in the ocean waters. The new volcano-like structure sits more than 1,600 meters from the water's surface. So, it's far too deep to pose a danger ...
Northwest Passage routes Envisat ASAR mosaic of the Arctic Ocean (September 2007), showing the most direct route of the Northwest Passage closed (yellow line) and the Northeast Passage partially opened (blue line). The dark grey colour represents the ice-free areas, while green represents areas with sea ice.
As the Arctic continues receiving energy from the sun during this time, the land, which is mostly free of snow by now, can warm up on clear days when the wind is not coming from the cold ocean. Over the Arctic Ocean the snow cover on the sea ice disappears and ponds of melt water start to form on the sea ice, further reducing the amount of ...
