The Adelaide has gone from strength to strength

The Adelaide has gone from strength to strength again this week.

More fishlife is starting to inhabit the wreck especially the inner areas. During a dive on Tuesday afternoon I surprised a long finned or Blue Morwong as it was nestling down for a nap in the Junior Sailors mess. The fish made a hasty retreat for the deck below and hid behind some machinery.

I also found another octopus, this one is much larger than the one found, near the intake vent on deck two. Wednesday saw us all swim over the side onto the sand where I found a huge Shovel Nosed shark half buried in the sand- It too didn't like the look of me and took off at a great rate of knots.

We had more overseas guests come along with us- they absolutely loved the wreck and the marine life.

  

Small Sargeant Baker on the Adelaid

 

One thing has been puzzling me and I think I have the answer now!

The main mast has been alive with fishlife, small Yakkas, Sea Pike, small Bream, colourful tropicals and Leather jackets- All the fish are too small for line fishos and I have noted sometimes, the mast early in the morning is quite lonely, whilst the inner sections are swarming with juvenile fish. 

 

Dolphins are seen swimming away from the wreck when I arrive early in the morning!

 

 

I think the dolphins are feeding on the juveniles and the juveniles are hiding inside the ship for safety- This can only mean the artificial reef is doing what it was intended to do and create a habitat.

 

I will keep monitoring the fish life and see for myself what is happening.

 

The hull is now almost completely covered in barnacles at the bow down to 33 metres. There are thousands of barnacles waving their tiny legs at the divers almost beckoning them to come explore the rest of the ship. 

 

Our overseas visiting divers are amazed at our wreck and are so jealous at the close proximity to the boat ramp. One diver from England last week told me, he travels for nearly an hour by boat to get to a site that is very good, but the penetration opportunities are nowhere near the Adelaide.

 

So far this week, we have certified divers for Enriched Air. Dave, Ben and Carrissa dived the wreck for longer bottom times and I asked the Rescue course to implement an Assessment plan for the Adelaide.

 

Still a lot more diving to be done and today I have found another tour you can follow me on.

 

 

 

The fundamentals of Buoyancy Control

The fundamentals of buoyancy control-

 

Over the last seven months I have taken real notice of the divers whilst diving the Adelaide. Some have come up so rusty they could crack whilst others, have cut their fingers pretty bad on the many barnacles now festooning the wreck.

I have realised for a time now,  buoyancy remains an important issue for a lot of divers-  so whether you are a  new diver struggling to perfect your buoyancy techniques or someone who is looking to polish on your already good skills- Here are a few tips to help you to fine tune your buoyancy .

 

Breath Control

Breathe in and you increase your displacement and buoyancy- you automatically tend to rise slightly, then when you exhale, you will tend to sink. 

 

Divers preparing to descend,  let all the air out of their BCD and then- "take in a big breathe to descend"- they tend to float about the surface, then when they finally do exhale, they descend like a brick- This sometimes causes divers to stress especially, as they grope around for more weights, they don't really require!

 

Now this technique does not require you to hold you breath, it’s a matter of timing your breathing and paying attention to how full or empty your lungs are to ascend or descend a little. 

A little bit of practice and breath control buoyancy becomes second nature- You can easily ascend or descend solely by breathing in and out.

 

Weight Distribution

 

Whenever we talk about buoyancy it’s stressed that you need to be wearing the right amount of weights in the first place. But, distributing your dive weights about you correctly is just as important as it can also make a big difference to your buoyancy. 

 

Weight distribution depends from diver to diver and according to the dive you are about to make. Typically, for a horizontal swimming position, that reduces drag, position your weights forward, towards your sides and stomach to help maintain a flat swimming position. 

Weight distribution is not just limited to the weights you wear, it also includes all the scuba gear and dive related equipment you carry about you on a dive, plus how it is worn. 

 

Be warned however- you could end up on your back or even upside down with this little test. 


Streamlining

Streamlining not only minimizes exertion, it also reduces air consumption by improving your overall hydrodynamics.

Believe it or not- This helps your diving skills quite a bit when your dive equipment is not poking out, hanging off you or getting dragged around by you. Make yourself tight and streamlined- you will notice a marked improvement in your buoyancy right away. 

 

Physical Fitness

Physical fitness is often overlooked as being important for diving but it can make a huge difference in your overall diving enjoyment.

Think about it for a while! Lean mass sinks, fat tissues float- which makes fitness important.

When you’re fit, you become sleeker and more naturally streamlined, this makes controlling your buoyancy and trim a whole lot easier.

 

So, what are you waiting for!

You want to become a better buoyancy diver? 

Trim level, breathe properly and tone up......

To blog or log?

The simple fact is-we can't be underwater all the time, I know that! 

 

Sometimes we need to do totally irrelevant actions like eating, sleeping, working, spending time with family, for me its filling tanks, cleaning boats etc. To rest my mind, one of the hobbies I enjoy most when I get the time, is to blog my dives- Yes, I said blogging and not logging. 

 

We all log our dives, but since the great invasion of the internet into our lives, I am seeing so many more divers using different medias to share their dives in a more interactive way.

Where before we would sit around the table at the back of the Dive shop writing up our logs, now a days we just blog about our dives on the internet.

I often use Facebook to entice people to blog their experiences. You can download software to blog with or do as I do, open a Google blog spot account.

 

Some blogs I keep private, others I share- 

 

You too, can create blogs, add a few photos, customise text and before your very eyes, a brief description of your experiences underwater appears before you. You  can then publish your dive info into your blog and instead of closing the book, you invite other divers to comment and add their opinions into your "Online Dive blog".

 

Strange you might think?  Not so strange if you understand the advantages of the internet. 

An old paper dive log book was a confidential piece of your life. You never shared your logbook!

 

I often have to prise divers fingers off  Logbooks, especially those divers who requested to join us on a Dive master program, because at the end of the day, this is your personal thoughts being exposed to the world,.

 

The real truth is- no one really cares to read it! Especially if you have taken time to add boring technical info like gas mixes, dive percentage program data, camera colour temp settings. This info never invites feedback.

 

Only divers understand when a diver recants the freedom, the excitement and the joy of a perfect dive. Only divers understand the feeling of pressure waves on your body during a drift dive.

Only divers appreciate the effort you took to take the perfect photo of that tiny shrimp in thre anenome.

Only divers understand the feeling of weightlessness you access when going underwater.

 

I am not a fan of heights- Going onto the roof to check the solar is a big deal for me, but I will happily drift along a drop off 1000 metres deep, this can easily allow ypou to share with people your inner self or demons, whichever sets you off!.

 

Divers also take their sport to extremes sometimes. 

 

Only this week Darren W. took the bold step to propose to Samantha underwater in Manly Shark tank.

Non divers would think it crazy, to be underwater in the first place- The nay sayers would reckon it would be safer diving than getting married in the first place. 

All I can say is congratulations to you both and lets hope they have a great life together. 

Sharks are the least of your problems......

 

In my personal view, I am still in the process of understanding why blogging is such an addiction for some and a chore for others. 

I guess it is like diving: it is not so much about the diving, it is about being able to share with the world, the amazing feeling you get everytime you touch the water.

 

I guess this where a dive computor like the New Mares Icon HD comes into play- The ICON HD allows you to upload photos, write short notes.

 

When someone invents a waterproof PDA this is when I will enjoy deco stops until then, I will happily while away a few moments of "ME time" and write my blog happy in the knowledge when old age sets in and I can't remember what I had for lunch- I can then recall the fun I used to have diving.

 

New Gear
If you have invested in a new scuba gear, you should by now have come to the realization that scuba gear does not come cheap.
LiquidSkin technology
The wheel of innovation keeps turning: At first sight, the newly designed X-Vision LiquidSkin is unique and stands apart from the rest. New colors are vibrant and match perfectly with Mares’ fins and snorkels.
Just How far is that?
One of the most important considerations for diving is the visibility, "vizo" or “viz” whatever you want to call it. Visibility especially very good "viz" or extremely clear water will make any dive site seem unreal, on the other hand, I remember a dive at Steves Bommie on the Great Barrier reef in '98 we had 2 to 3 metres viz, this was terrible visibility for a divesite that is usually a great dive.
So you scuba dive! What's the buzz?
Learning to scuba dive is a simple, rewarding, exhilarating process. You may find portions of the training difficult, but that very first breath of air underwater will never be forgotten. The real joy comes learning to dive and becoming a safe, competent diver.
