It is one of the main centers of action in the atmospheric circulation of the Northern Hemisphere. In the north pole winter time, the subpolar low pressure belt develops well only over oceans and this low pressure is divided in two parts by Asia and North America continent in between them in a circle. The Aleutian low is the one lying east of Japan. The second part is the Icelandic low lying in the Norwegian Sea. The Aleutian Low is characterized by many strong cyclones . Cyclones which form in the subpolar latitudes in the North Pacific typically slow down and reach maximum intensity in the area of the Aleutian Low. In summer, remnants of typhoons can go past the Aleutian low and strengthen a little. References C.Michael Hogan. 2011. http www.eoearth.org article Gulf of Alaska?topic 49523 Gulf of Alaska .

It is classified as a marginal trench in the east as it runs along the margin of the continent, and as an island arc where it runs through the open sea. The trench extends for 3,400 km from a triple junction in the west with the Ulakhan Fault and the northern end of the Kuril Kamchatka Trench , to a junction with the northern end of the Queen Charlotte Fault system in the east. The Aleutian Trench is a convergent plate boundary. The trench forms part of the boundary between two tectonic plate s. Here, the Pacific Plate is being subducted under the North American Plate at an angle of nearly 45 degrees. This process has created the Aleutian Arc . The deepest part of the Aleutian trench has been measured at Convert 7679 m ft 0 . Fact date March 2011 North of the trench, a string of volcanoes and associated islands have formed where melting of the crust has been caused by the descending plate beneath them.

It extends 3,000 km from the Kamchatka peninsula in the west to the Gulf of Alaska in the east. Unimak Pass at the southwestern end of the Alaska Peninsula marks the eastward transition from an intra oceanic in the west to a continental arc in the east. Due to the arcuate geometry of the trench, the relative velocity vector changes from almost trench normal in the Gulf of Alaska to almost trench parallel in the west.

    merge Baidarka date December 2011 Image Sea otter hunters 1896.jpg thumb right 200px Aleut people Aleut men in Unalaska in 1896 , with waterproof kayak gear and garments The Aleutian Baidarka or Aleutian kayak was the watercraft created by the native Aleut people Aleut or Unangan people of the Aleutian Islands . The Aleut people were surrounded by treacherous waters and required water transportation and a hunting vessel. Due to the geography and climate of the Aleutian Islands, trees and wood were in scarce supply and the people relied primarily on driftwood to create the framework of the kayak, which was covered with the skins of sea mammals. Two types of boats were created, one with a covered deck, the hunting kayak and another that was open and capable of carrying goods and people from one island to another. Before the arrival of the Russia ns, the one hole bidarkas kayaks were found in abundance, along with some two hole boats. The Russian influence, due their presence on the islands to hunt fur bearing animals, on the design of the kayaks was significant and resulted in three hole kayaks. These were probably configured with the stern man paddling and guiding the craft, while the bow man was responsible for using the throwing board in the hunt, with the hunt boss in the middle directing the hunt. Some characteristics of these early kayaks are described in the words of Veniaminov from the island of Atka in 1840 blockquote ...The baidarki of the present day Aleuts are no longer as perfect as those of the former Aleut riders. At that time, in the hands of excellent riders, they were so speedy that birds could not outrun them. They were so narrow and sharp keeled that they could not stand upright in the water without a rider, and so light that a seven year old child could easily carry them. blockquote See also Baidarka Kayak Unreferenced date October 2007 Canoeing and kayaking Category Kayaks Category Aleuts ...   more details

They used kayak s, atlatl s and harpoons to kill sea mammals for sustenance. Around AD 1150 Aleutian houses increased considerably in size. Food was stored in special chambers inside the house and weaponry was becoming more common around these sites. The sustenance pattern changed from relying on sea mammals to eating mostly salmon.

  1. Aleutian Disease

    Aleutian Disease also ADV , for Aleutian Disease Virus or Mink Plasmacytosis is a highly contagious parvovirus affecting mustelid s, causing spontaneous abortion and death in mink s and ferrets .

Retrieved April 7, 2008. ref In the 1960s, it was common practice for mink ranchers to make their own distemper vaccines by Homogenization chemistry homogenizing tissue from distemper infected mink, making suspensions, and injecting all the mink on their ranch. This practice led to a severe outbreak of AD on a Connecticut ranch, with a mortality of almost 100 in less than 6 months. ref name Dr. Adrian Dealey http homepage.ntlworld.com ferreter aleutian01.htm.
