Unalaska. It is a small town (geographic location: 53 ° 53′20 ″ N 166 ° 31′38 ″ W) on Unalaska Island and the neighboring island of Amaknak in the Aleutian Islands (Alaska). The city has a total area of 549.9 km². The number of residents registered in 2005 was 4,347. Almost all the port facilities are on Amaknak Island, better known as Dutch Harbor or simply Dutch as it is called by the crab fishermen of the Bering Sea. The port is connected to Unalaska by a bridge. The name “Unalaska” is probably a derivation of the Russian name “Ounalashka”.
The island was discovered by Vitus Bering in 1741. In 1759 the Russians established themselves making a permanent settlement, but four years later it was destroyed by the Aleuts, along with four merchant ships. The massacre claimed the lives of 162 Russian settlers. The survivors managed to hold their position until 1764, when they were rescued by the Russians. This event provoked very bloody reprisals against the natives, which cost the lives of about 5,000 Aleuts.
The expedition of Esteban José Martínez and Gonzalo López de Haro of 1778 explored the coast of Alaska to Unalaska Island, marking the western end of what the Spanish explored in the region. In Moscow on May 31, 1988, President Ronald Reagan mentioned the meeting of Americans and Russians on this island in the 19th century as an example of long-standing friendship between the United States and Russia.

In 1768, Unalaska became in a Russian trading port for the sea industry. In 1825, the Russian Orthodox Church built a church in Unalaska. The priest, Ivan Veniaminov, composed the first Aleutian writing system with local help, and translated the holy scriptures into that language. During this time, (between 1830 and 1840), only 200 to 400 Aleuts lived in Unalaska. On June 3, 1942, during World War II, Unalaska was attacked by the Japanese. Most of the island’s native residents were sent to Southeast Alaska during the war.
The island is located to the west of Akutan Island, from which it is separated by the Akutan Pass, and to the east of Umnak Island, from which it is separated by the Umnak Pass.

We base the comfort level of humidity on the dew point, as this determines whether sweat will evaporate from the skin, thereby cooling the body. When the dew points are lower it feels drier and when they are high it feels more humid. Unlike the temperature, which generally varies considerably between night and day, the dew point tends to change more slowly, so even though the temperature drops at night, on a humid day the night is generally humid. Unalaska’s perceived humidity level, measured by the percentage of time that the humidity comfort level is muggy, oppressive, or unbearable, does not vary significantly throughout the year, and remains virtually constant at 0%.

Unalaska Harbor is the main port and base of the Bering Sea crab fishing industry. It has been the largest fishing port in the United States in terms of the volume of shellfish caught, from 1981 to 2000, and in terms of value per catch. However, since 2000, the port of New Beford, Massachusetts, has surpassed it in that category.
A pilot project in the port of Unalaska is producing biodiesel from fish oil from the local fishing industry in conjunction with the University of Fairbanks Alaska. The economic use of fish oil is rare, and Alaskan communities are highly dependent on diesel power generation. Local factories generate 3.5 million tons of fish oil annually.
