Saturday, August 14th, 2010

Professional deep sea diving or commercial diving is a profession that is not for all people. In this profession, you must be in first-class physical condition and you also need to have a sharp mind. Being a commercial diver is not just about knowing how to weld pipes undersea and being able to handle explosives, there are a lot of specialty studies that you can focus on in commercial diving.

These days, there are specialist schools for professional diving. There, you will be given the chance to develop into a certified commercial diver as well as take specialty courses that appeal to you the most.

Basically, most commercial divers take welding courses. If you follow the specialist underwater welding course, you will learn the skills necessary to make high quality fillet welds. You will also be introduced to theories concerning the welding process and safe working practice while welding undersea.

In this course, each issue will be covered with lectures and actual test situations where you will be taken underwater for a simulated welding situation.Normally, you will learn nine different topics on this course.

The first will cover safe undersea welding procedures; the second, welding plant and equipment; the third, techniques; the fourth, the preparation of the weld; the fifth, welding terminology and electrodes; the sixth, basic weldability and common weld defects; the seventh, how to monitor and control welding operations; the eighth, quality assurance and control and the ninth is joining steel plates using the three standard welding techniques.

Taking an underwater welding course can provide you with a great deal of employment opportunities in a commercial diving career. By becoming a certified undersea welder, you will be in demand by the shipping, construction and oil and gas industries.

Air mixed gas commercial diving is also a specialist course in the commercial diving industry. On this one, you will be taught about the different gas mixes that divers breathe. Regular air, nitrox, trimix, whatever, you will be taught how to mix them all.

A pressure tolerance test is also integrated in this particular course. You will also learn about the effects of certain gases on the body when diving. For instance, you will be taught about nitrogen and its hallucinogenic effects on the brain when breathed under pressure, and you will also be taught about oxygen toxicity and why helium is a preferred gas for breathing when diving in very deep waters.

You will also be taught about decompression and dive medicines as well as hyperbaric medication. Safety planning is another critical part of the course as well as the commercial uses of scuba.

Underwater construction is also covered under this course as well as inland diving and equipment maintenance, especially that of the gas systems.

The diver medic specialist is another specialty course in commercial diving. After passing it, you will become a dive medical technician who will be responsible for making safer and better prepared dives.

You will be taught about the effects of protracted diving on the body and also about the various ailments that divers can experience, such as decompression sickness and extreme fatigue.

Deep Sea Fishing: Knowing The Tides

Sunday, August 1st, 2010

It might seem weird but a comprehensive understanding of the tides and their result on your fishing area can pay big dividends. In fact, it is rated a major key to successful deep sea fishing by experts. Most fishing guides and charter-boat captains know this secret. They make detailed studies of currents, tides, and how they affect fishing on their area.

However, it is depressing to say, that a lot of amateur deep sea anglers give very little thought to these key details. In deed, some anglers do not pay any attention to them at all. Then they ask themselves why other fishermen catch all the fish and they do not. Nevertheless, there are those who do comprehend that tides have an effect on their fishing, but they do not know exactly how or why.

These anglers usually waste hours trolling, casting and sinker bouncing even when the tide is not first-class. However, the deep sea angler who knows his tides can pick in advanced the most favourable fishing periods and concentrate his efforts during those periods, which means that you can have fewer wasted days and get more fish during your deep sea fishing trips.

We do not need to delve into the science of tides here, except to point out that tides are thanks to the gravitational forces that are brought about by the Sun and the moon. Since the moon is nearer the Earth, it has greater influence on tides than the Sun.

When the tide is up, water moves towards the land. This is also known as a “flood tide”. When the tide drops, making its way back out, it is called an “ebb tide”. The time when it does not flow either way is called the “slack tide”. It takes a period of about six hours for it to rise, and six hours to ebb. For every 24 hours these tides occur about 50 minutes later than the last time.

They also fluctuate with regard to the degree that they rise or fall. The highest tides occur when the Sn and moon are located on the same side of the Earth in a direct line. This kind of tide is called a “Spring tide”, which happens during new-moon and full-moon periods.

During these periods, both low and high tides are higher than their usual level. However, during the last and first quarter phases of the moon, tides do not rise or fall that much. These are termed as “neap tides”.

So which of these tides are helpful and which are not? To start off with, most experts believe that flowing tides or currents are usually more productive than when there are no currents or tides. Therefore, a “slack” tide will rarely generate a good catch.

You can take even more advantage from tides by knowing when to go. The time in which an incoming tide starts is rated one of the most productive periods for fishing, particularly if you are targeting game fish like bluefish, striped bass, channel bass, and weakfish.

During the periods of slack water, small bait fish are apt to scatter, and having a lack of strong currents to contend with, they are able to swim faster and therefore escape their predators.

However, when tides start moving, such small bait fish are at the mercy of strong rips and current. Therefore, they are easier to find and catch for stripers and other kinds of game fish. When an outgoing tide starts is another good time to fish, simply for the same logic. In general, the change of tide, whether it be low or high, is actually the best time to do your fishing.
