The eye squeeze effect

20 07 2010

Eye squeeze is an effect which usually happens along with what is known by divers as mask squeeze. Mask squeeze can produce different symptoms and effects, but what is called as eye squeeze is the most usual one. Although most of the times this doesn’t cause a serious problem, it is very usual that it happens and it is interesting to learn why it does.

The air contained in the space within your face and your mask must have a pressure equal to the blood pressure of the face. If this doesn’t happen, and the mask air pressure is unequal to the blood one, this would cause the diver to suffer an eye squeeze. Our physical pressure should be equalized with the pressure of the exterior and it is important that we know how to maintain it.

Eye squeeze causes divers to have a reddish spot of blood in the white of their eyes. Sometimes finding this in their eyes scares divers, but usually it is not dangerous and looks worse than what it actually is. Even when it usually is not dangerous, it is always advisable that a diver who finds this red spot in their eyes consults with a physician about it.

One of the ways in which this problem can be avoided is by learning how to breathe properly in order to maintain the balance the mask air pressure and the facial blood one. If you exhale air through your nose, this will add air to the mask space, and therefore the air amount and pressure would vary causing a loss of balance. Therefore, divers should avoid exhaling through their nose or, otherwise, this could cause them to suffer an eye squeeze.

Besides the reddish spot in the white of the eye, this problem known as mask squeeze can cause other effects as well. Among some other things which might happen due to this pressure variation, a diver can suffer an injury in some of his facial tissues or in the skin area located around the eyes. These effects might show their symptoms by producing a variation in the color of the area, such as turning it into a red color or causing it to be bruised.

Never go diving without a magnetic compass

17 06 2010

 

A magnetic compass is an indispensable device which divers should always carry and be able to consult while they dive. The compass might make the difference for a lost diver allowing him to find the shore, which he couldn’t do without it. Having a magnetic compass is crucial at the moment of wishing to know where we are while being at the water.

Whenever a diver is checking on his equipment and making sure he has everything he needs, one of the first things he should check is for his compass. A diver should never go into the sea without having this device with him. It doesn’t matter if it is an experienced diver or not, any one could get lost if they didn’t have a magnetic compass with them.

Using a magnetic compass is not as easy as it might seem and it might take some practice before the diver is able to use it and read it properly. Actually, many divers tend to feel like they don’t need to learn or practice with their compass, and they don’t find out their mistake until they are into the water and need the help of this device.

Any sea related sport requires a compass as an important piece of equipment. It is fundamental for navigators to use compasses and consult them, and actually they could not practice their activity without the information which these devices provide. Actually, a compass turns into a safety device due to the importance of the help it gives for those who consult it while being at the sea, whether they are navigating, diving, or practicing any other related activity.

It is very easy to get lost while being at the sea, and having a compass might be the only way to learn where we are and in which direction we should move. When all we have around us is sea and it looks all alike, there might be no way for us to know where we should go. Therefore, having a magnetic compass and learning how to properly follow its indications is vital for all divers.

The use of an octopus and the buddy system while diving

24 05 2010

An octopus is one of the most recommended ways in which two divers can backup each other with air in case their own fails or they run out of it before they had expected. This way, an octopus and the buddy system allow divers to count on a second air source as long as their buddy is close enough and disposed to share their air, which not always happens.

There are some objections that are often done regarding the octopus and the buddy system. According to these objections, an octopus is not the best solution at the time of being in an emergency and running out of air, and divers should find other solutions instead of it.

Relying on an octopus and another person whom you might not even know while running out of air deep in the water is not always the best idea. The octopus and buddy system takes a good predisposition and relines from both parts which can assure that at the eventuality in which one of them runs out of air, the other will share his remaining air with the first one. If this doesn’t happen, that person could die before reaching the surface, so it is a really serious matter and those who use this system must know the other person and rely on each other.

According to statistics, many diving accidents occur when a diver runs out of air and tries to reach his buddy’s octopus unsuccessfully. Therefore, and according to some professional divers, using the buddy system and the octopus can be riskier than not using it. Once divers use the octopus based on the buddy system they might forget about checking their own air since they rely on their buddy and this leads to running out of it more often.

Another objection often said against the use of an octopus is that when one of the divers runs out of air and asks the second person to share theirs, if they started diving together then this second person will probably be also about to run out of it as well. Despite all this objections, the use of an octopus and the buddy system is still the backup system used by many divers and which can be very advantageous when used by two people who can trust and rely on each other.

Stranded boat turns attraction in Rio Grande do Norte

17 05 2010

A boat became stranded for six months attraction on the beach of Buzios, on the southern coast of Rio Grande do Norte, the same place where he arrived. Before getting bogged down, the fishing boat came from Nigeria and spent four days adrift.

The six crew members aboard have returned to their respective countries and the boat turned tourist attraction. Surfer André Marques account that the route of the site is buggy and the tourists come down to take pictures. The appeal of surfers now is that the boat go to the bottom of the sea and turn attraction for divers.





Diving points – Santa Catarina

22 04 2010


Santa Catarina
has incredible potential for diving. Its coastline is beautiful, with crystal-clear waters and teeming with marine life.

Highlights
Bombinhas/Florianópolis
– Despite political restrictions, there are incredible, not to be missed dives.

Florianópolis and the town of Bombinhas, sixty kilometers away, are the starting-points for the region’s most important dives. When the Arvoredo Biological Reserve was closed again in 2003, Bombinhas was most severely affected. The town lost its main points on Galé Island and tourists ignored the town.

Local diving  operators now take over two hours to sail to the permitted area in the south of Arvoredo. They have to share the acess points with those of Florianópolis.

Parcel do Boi

One of the best dives on the southern end of Arvoredo. The reef begins roughly ten meters deep and the mounds rise to seven meters above the surface. At its deepest aprt, to the southwest, there is a scattered wreckage and a great variety of sea life. Large schools of open water fish such as amberjack and anchovies. Turtles are also often found.

Saco do Capim

This saco or cove gets its name from the characteristic grass growing in this part of the island, one of the best know locations. The bottom is overgrown by zoanthids. In the most sheltered part lie the debris of the Granada, an old wooden-hulled fishing vessel that sank after engine failure. Seahorses and green turtles are often found.

Saco do Batismo

The most sought-after site for those about to make their first dive, and yet one that can surprise even the most experienced divers. The rocky seabed makes cavers where angelfish and crevasse-dwelling shoals are found. Turtles can be seen at rest, in the direction os Saco do Capim.

Baía das Tartarugas

The seabed is made up of several ledges. This is one the best place on Arvoredo for observing turtles. Divers will sometimes also find large schools of sea bass. One of the region’s most interesting caverns lies between this bay and Engenho Bay.

Baía do Engenho

There was a sugar mill here once, and the bay also was a refuge for fishermen. It has since become an ideal training area for all levels of divers. There is a shallower part, some eight meters deep, where the rocks meet the sand. It gets as deep as eighteen meters toward the light house, and larger fish can be found there. Take care, however, with the strong current that drags the diver toward the lighthouse.

Baía do Farol

Facing the Navy supply-base for the lighthouse. The seabed is almost entirely rocky and overgrown with soft coral (sea fans), and very large Atlantic and common Groupers can be seen.

Ponta do Farol

This is the deepest dive in the reserve. The currents are often very strong, but the view is well worth it. A huge rock face, teeming with enormous open water fish. Be careful, though: the speed of the currents is often proportional to the beauty of the rock formation.
