Marine Technology

I own a boat and my job is to take people for sailing trips that are fun and adventurous. Usually every weekend I am near sea shore and tourists who like to explore the ocean approach me.The typical marine autopilots system can eliminate the need for constant steering by a captain. Marine autopiloting can help to control the ship rudder or access the control panel or rudder drive and head. Of course, there is only one way to determine which marine autopilots are the best on the market (and there are plenty at that). That would be to sample these systems and find out which ones provide the most effective heading and how the sensor tracks a course in windy conditions.One of the newest developments in autopilot technology is the use of microprocessors. This allows marine autopilots to handle more complex operations such as automatic compensation for asymmetry in steering, counter-rudder and course tracking and of course automatic sea state adaptation.

In previous decades, these devices were only used by very costly commercial ships. Nowadays these sophisticated devices are being marketed to the individual boater.

Primarily, the biggest difference in today's Marine VHF market is portability. Whereas 25 years ago, if you wanted to scan the radio channels on your VHF radio, you had to stop what you were doing and go to where your unit was mounted. Today you can have a portable, hand held unit to carry around with you wherever you go on your boat. If you have a boat with a sun deck and you like to catch some sun while drinking a few beverages, a hand held Marine VHF unit is perfect for you. Another point for hand held units, and probably the most important, is that the sound quality does not fall off one bit in most quality units.Can you use your satellite phone anywhere in the world? Not exactly, though potentially satellite TV could do this. The main restriction here is that satellite companies purposely limit their services to one region for better overall service and for legal purposes. For instance, in some countries it would be illegal for you to use marine satellite phones, because that might interfere with their local frequencies, which could result in confusion.

Much like sonar technology, which bounces sound waves off objects below the surface of the water, marine GPS devices use high-frequency low-power radio signals emitted from satellites in orbit around the Earth to determine your position on the water. When these signals hit your GPS receiver, the receiver calculates an x-y coordinate marking your position.Another important item in marine electronics is that of water makers. Water makers allow personnel to "make" their own water, by filtering out the salt content in the usually undrinkable seawater. Remember that seawater, though not always poisonous, is counterproductive. You take in so much salt that you need more liquids to push it out; after a short time you would eventually start to thirst very badly. The only option for extended sea journeys is taking along a water maker system.

Marine Technology

Marine technology refers to a vast umbrella of elements that have helped us to explore what lives in bodies of water. This includes saltwater of the oceans and the freshwater of various lakes. It is amazing how many living things are found in water. Learning about them helps use to find out how they affect those living on land. It also helps us to understand why keeping these bodies of water free from pollution are so important.

There have been many breakthroughs in the way of underwater technology over the years. As a result, divers are able to go to the depths of these water masses. They can evaluate what is living there, observe it in its natural habitat, and document that information. The use of such information means that we also know how to protect certain species of live in the water they could become extinct without our help.

Thanks to forms of underwater technology such as cameras and video recorders, all of us can share in those experiences. While most of us will never dive into the depths of these waters we can watch documentaries, view photos, and even watch videos online. Of course there are some places in the water that humans cant safely go.

That doesnt mean we cant explore them though. Marine technology allows for the use of ROV (Remotely Operated Vehicles) to be used in their place. They can be easily navigated through the waters to the desired location. A cable is used to release them off a boat. They have video cameras on them that relay information back to the humans who are safely on the boats.

The downside is that an ROV costs an estimated million. That is a large amount of money to invest in the equipment. Yet the design of them makes them safe to use as they dont disrupt the environment. They have also provided us with substantial information about aquatic life that we wont have without the use of such equipment.

A very similar type of technology used id the AUV (Autonomous Underwater Vehicles). They are much smaller than ROVs and about half the cost. They can get into locations that are smaller too. However, they can be tougher to navigate through the waters. The AUV though is often used for a variety of underwater investigations.

Sonar stands for Sound Navigation and Ranging. This is a big part of marine biology that was first used on the water by vessels so that they could detect land masses and even other vessels around them. Today it is used to help send information back and forth from the boats to the underwater equipment.

Sonar is also used to help locate the ideal place for observing various forms of aquatic life. Many people use this type of marine technology too when they are navigating a boat or even trying to locate fish in the waters before they toss their line out. All of this technology has certainly allowed us to explore what lives in our water in new ways.
