To most enthusiasts, Arctic is best known for their Freezer line of CPU coolers as well as their thermal compound called MX-2 and MX-4. [2] The Freezer line of coolers is available in different fan speed, cooling capacity and motherboard compatibility [3] to cater the needs of different type of users from HTPC users to enthusiasts and overclockers.
Cooling capacity is the measure of a cooling system's ability to remove heat. [1] It is equivalent to the heat supplied to the evaporator/boiler part of the refrigeration cycle and may be called the "rate of refrigeration" or "refrigeration capacity".
Some reefers are equipped with a water cooling system, which can be used if the reefer is stored below deck on a vessel without adequate ventilation to remove the heat generated. [ 2 ] Water cooling systems are more expensive than air current ventilation to remove heat from cargo holds, and the use of water cooling systems is declining. [ 1 ]
A map of the Arctic. The red line is the 10 °C isotherm in July, commonly used to define the Arctic region; also shown is the Arctic Circle. The white area shows the average minimum extent of sea ice in summer as of 1975. [1] The climate of the Arctic is characterized by long, cold winters
The North American Arctic is composed of the northern polar regions of Alaska (USA), Northern Canada and Greenland. [1] Major bodies of water include the Arctic Ocean, Hudson Bay, the Gulf of Alaska and North Atlantic Ocean. [2] The North American Arctic lies above the Arctic Circle. [3] It is part of the Arctic, which is the northernmost ...
The number of wildfires in the Arctic Circle has increased. In 2020, Arctic wildfire CO 2 emissions broke a new record, peaking at 244 megatonnes of carbon dioxide emitted. [125] This is due to the burning of peatlands, carbon-rich soils that originate from the accumulation of waterlogged plants which are mostly found at Arctic latitudes. [125]
Life in the Freezer is a BBC nature documentary series written and presented by David Attenborough, first transmitted in the United Kingdom from 18 November 1993. A study of the seasonal cycle of Antarctica , it was the first of Attenborough's more specialised surveys following his major trilogy that began with Life on Earth .
RV Polarstern (meaning pole star) is a German research icebreaker of the Alfred Wegener Institute for Polar and Marine Research (AWI) in Bremerhaven, Germany. Polarstern was built by Howaldtswerke-Deutsche Werft in Kiel and Nobiskrug in Rendsburg, was commissioned in 1982, and is mainly used for research in the Arctic and Antarctica.
