Out at sea, with seemingly limitless supplies of salty water, does not seem the ideal place for sophisticated electrical equipment. Surprisingly, 21st century navigation is becoming increasingly dependent on marine electronics Juneau. Everything from the cook's video game player to the captain's cell phone and the satellite navigation system run on black boxes that could be completely destroyed by a single drop of what lies all around them.
The change from old-fashioned paper charts to navigating by celestial satellite has been proceeding gradually. The term navigation relates to any task involving the discernment of the current position of a body and the direction in which it is travelling. This applies to a hiker in the mountains with armed with nothing but a compass. To date, cell phone signals are still a bit dodgy in the mountains.
While it would seem a difficult task to get a cell signal out at sea, a new gadget has been invented that enables precisely that. This is called a SatSleeve and it is designed to allow fluid communications from land to sea. It is capable of receiving vocal communications as well as text messages and can even allow the user to connect to the Internet.
Seafarers will also appreciate the newly-launched flexible TV sets. They have two advantages at sea. For one, they can be bent around to fit close spaces and two, they can be rolled up and put away when not in use, like when this week's episode of NCIS has been viewed.
Soon, bubble and ultrasound technologies may be used to prevent hull fouling. Ultrasonic waves can be used to reduce microbial contact on hulls. Multiple vibration devices fitted inside a ship's hull may be networked to a power supply and control panel. This can save time in dry dock as it is one less chore to perform.
Juneau, the state capital of Alaska, is located on the Gastineau Channel between the panhandle and Douglas Island. Prior to 1906, the capital of Alaska was Sitka. The name change was at the insistence of the United States Congress. In terms of area, Juneau is the second largest city in the United States. It is named after former gold prospector, Joe Juneau. Prior to that, it was called Harrisburg, after Joe's partner in mining; previously, it was also named Rockville.
The climate in Juneau is a lot milder than most people would give it credit for, even in the winter months. The high heat capacity of the mighty Pacific Ocean sees to it that the average temperature in winter, experienced in the month of January, rarely gets below -5 degrees Centigrade. In the month of July, when the city experiences its warmest temperatures, it remains a comfortable 18.5 degrees Centigrade.
In terms of acreage, Juneau is the second-largest city in the United States. In terms of population, it is the largest city and borough, with a population of more than 32,000 at the last census. There are 13 public schools in the area, serving elementary, middle and high school students. The local college is the University of Alaska Southeast.
