Air trapped in hood??

Most divers will at some point get a hood that is slightly too large and it will bubble up making you more positively buoyant with air trapped and looking like a cone head. Well with a simple search on the net it is easy to find how to sort this so I am not claiming anything on this one but felt it was worth mentioning.

The easiest way to solve this is to get a wire coat hanger, straighten it out and heat the end up till it is red hot, not hotter else you will set fire to the neoprene and have the hood outside if you can or at least open the windows for the fumes. I stood mine on an axle stand which seemed to work really well, but anything that lifts the hood and keeps it steady while you are concentrating on making the holes would work.

This is hot enough to melt but not set on fire.

What I found was that none of the things I read on it mentioned one important thing, which is really simple and basic physics. Turn your hood inside out, melt the hole from the inside and you will get a thin funnel to the hole and a smaller and neater hole on the external side. If you think about how you are positioned in the water then the front hole would be melted at a slight angle back from the front of the hood and the rear holes would be made by pushing the wire through toward the back of the hood, it doesn’t have to be massive channels but will help with the flow of air out of the hood. If you do not make the channels and go for a level hole through, still make it inside out as will get a neater hole on the external.

This is what not to do, melted from the outside.

As you can see neater holes, but this is on the inside on my hood.

You will need a pair of pliers to hold the wire as you heat it, and then move it to where you have your hood. I have not been diving yet to try this out but as soon as I do I will let you know the outcome of the wise information that many a diver that has gone before me. I made 4 holes in my hood, and 3 or 4 seems to be the amount that is advised on the many posts you will find about this, in a few weeks when the water temperature has increased I will know if it works or if I have ruined my hood, so if you try this I hold no responsibility for your kit but many have before and seem happy with it.

Baltic Sea Anomoly – Latest

The latest news on the Baltic sea anomoly has been released, it is not something that is man-made, or extra-terrestrial but by the first images released on the 15th June 2012 it appears to be a granite dome or Laccolith,  that would have been formed when the area surrounding the Baltic was volcanicly active. It also still has its magma pillar that would have formed beneath it when the intrusive granite cooled, creating the mushroom shape the Ocean-X Team found on their latest dive to the site. What still needs to be explained are the circles of rocks over the top of the site that (according to Linberg) have black soot in them and could possibly be small fires leading to the possibility that some time over the last 300,000 years man was using the site in some way.

There is a short video in the local Swedish paper that has been following the adventures of the Ocean-X Team here

When an intrusion of magma is forced at high pressures between stratified layers, the layers above buckle (or are uplifted) allowing the intrusion to form a near perfect dome, then over millions of years as the area was covered with water and Ice, the top layers are eroded away leaving what has been discovered, commonly known in the Geological world as a Lacolith.

The mystery surrounding the object has left many on the Facebook page and Ocean-X forum dumb-founded and still trying to come up with something of significant importance in their belief of the object.

Today a team of explorers are leaving the Swedish port of Norrtälje and are going to be getting to the bottom of a mysterious object they came across this time last year 65m down in the Baltic Sea. The radar image is unclear but theories have ranged from the millenium falcon to a plug in the bottom of the ocean. Well in another couple of days we will find out once the team have got back to the site and sent down an ROV to explore it.

Personally I think it might be an ancient settlement of some kind, because before the 2km thick ice sheet melted that covered most of the northern hemisphere at the end of the last ice age, the sea level was about 120m lower than it is today. As the North Sea that divides the UK and Europe was a mass of open land back then called doggerland, it is not that far from the area this is located at and would likely have had some of our ancestors living there. The size of the anomoly would indicate it is an area that a small group could live in, as shown here on the comparison with a Boeing 747 from the Ocean Explorer team’s website. I am just speculating though based on evidence of other settlement areas found and studied around the world between 40m and 120m deep as it may just be a rock formation that randomly formed through deposition and erosion to create this strange anomoly that is less clear than man made anomolies on the radar images.

Good luck to them, and as the world is watching we can all hope the weather holds out for them to study this anomoly.
