The special winch is a key component and will help provide continuous physical and biogeochemical data from the surface of the Arctic Ocean in the Fram Strait area. The winch will hover at a depth of about 150m on a long, anchored rope that rises vertically in the water. From this ...
A summary is presented of the Surface Heat Budget of the Arctic Ocean (SHEBA) project, with a focus on the field experiment that was conducted from October 1997 to October 1998. The primary objective of the field work was to collect ocean, ice, and atmospheric datasets over a full annual ...

The earliest record of the existence of the Arctic Ocean was made in 325 BC, when Pytheas of Massilia made an account of a journey to a land where the sun sets for only three hours a day, and the water is replaced by a substance (loose sea ice) that you can’t walk or sail on....

The Arctic Ocean- the realm of ice and silence The Arctic Ocean, which lies between Canada and Siberia, is the smallest ocean on the planet. It is the most mysterious, because it is almost completely hidden under a huge layer of ice. The Arctic
In the Arctic Ocean the high river runoff and the net precipitation lead to a density decrease in the surface layers and heat loss at the sea surface results in the formation and maintenance of a permanent sea-ice cover. Brine ejected by freezing creates dense waters on the Arctic Ocean ...
Almost all surface based measurements have been made at coastal observatories, but most of the active processing of the air is believed to occur near or at the surface of the Arctic Ocean itself. A major objective of the OASIS (Ocean Atmosphere Sea Ice and Snow) program during the ...
surface waters and seafloor (ref.7and references therein). Abundance and distribution of microplastics, especially those in smaller size categories (<250 µm) throughout the vast ocean interior remain virtually unknown except for one full-depth (8–4400 m) survey in the Arctic Central Basin...
Deep beneath the frozen surface of the Arctic swims a whale with a spiral tusk (螺旋角) growing on its head — the narwhal (独角鲸). Biologists have long debated the purpose of male narwhals’ tusks. The tusks, like those of elephants, are actually thin long teeth. And since narwhals...
