Ice in the Arctic Ocean melted to its second lowest level on record this summer, triggered by global warming along with natural forces, U.S. scientists reported Monday. [37] Atlantic Water has the same salinity as Arctic Bottom Water but is much warmer (up to 3 °C [37 °F]). It's the climate change diet and scientists say it's not good. It is fed by the freshwater input of the big Siberian and Canadian streams (Ob, Yenisei, Lena, Mackenzie), the water of which quasi floats on the saltier, denser, deeper ocean water. It is nearly encompassed entirely by land. The Polaris operates mainly in the Baltic but can also reach large parts of the Arctic Ocean during the summer months. Due to the pronounced seasonality of 2–6 months of midnight sun and polar night[57] in the Arctic Ocean, the primary production of photosynthesizing organisms such as ice algae and phytoplankton is limited to the spring and summer months (March/April to September[58]). The low shifts to center over the North Pole in the summer. It covers an area of approximately 14,056,000 square kilometers (5,427,000 square miles), which is more than the area of Europe. ANCHORAGE, Alaska (AP) — Some polar bears in the Arctic are shedding pounds during the time they should be beefing up, a new study shows. Zones of compression also arise, where the ice piles up to form pack ice.[43][44][45]. ANCHORAGE, Alaska (AP) — A lawsuit challenging President Donald Trump's reversal of a ban on petroleum drilling in most of the Arctic Ocean and Atlantic underwater canyons can move forward. Better understanding of the origin of the Arctic Ocean’s basins and ridges is critical for reconstructing the paleoclimatic evolution of the ocean and for understanding its relevance to global environmental changes. Such speculations provided incentives for adventurous men to risk the hazards of severe climate and fear of the unknown to further geographic knowledge and national and personal prosperity.

Lion's mane jellyfish are abundant in the waters of the Arctic, and the banded gunnel is the only species of gunnel that lives in the ocean. Within the last few years, a significant amount of interest has developed in the Arctic Ocean and its seafloor features. THE ARCTIC CIRCLE (AP) — More than a century has passed since the first successful transit of the treacherous, ice-bound Northwest Passage by Norwegian explorer Roald Amundsen in 1906. The Arctic Ocean is the ocean around the North Pole.The most northern parts of Eurasia and North America are around the Arctic Ocean.
