A day without diving is like a day without sunshine!

  • Three Golden Rules

    Short and simple:

    Use a checklist to prepare your rebreather.

    Complete a five minute pre-breathe with a blocked nose while safely seated and paying attention.

    Never dive a rebreather with a known fault.

  • Canada’s Water Supply – Abundant Yet Critical

    Canada possesses somewhere between 6 and 9 per cent of the world’s renewable fresh water, yet only 0.5 per cent of the global population. From an ecological perspective, it might seem like that supply is abundant yet we really have no water to spare. Canada has 7% of the world’s land mass – meaning we have just about enough water to meet the ecological needs of our land mass (Institute for Research on Public Policy, Canada’s Water Challenges). To complicate matters, the renewable supply of water is expected to decrease with climate change (Natural Resources Canada, Canada’s Water Budget).

     

     

  • Out of Gas in the Dark!

    Dealing with a silt out and gas sharing scenario in the darkness of a cave can be overwhelming, but you will learn to master this skill during a CCR Cave Diving program. This video serves as a training preview or refresher.

  • Last Minute Checks

    Most rebreather manufacturers provide students with a last-minute checklist that can be completed right before jumping off a boat or even in the water prior to descent. If your rebreather does not have such a list consider reciting a short mantra as you approach the “danger zone” before a dive. The danger zone could be the top of a set of stairs leading to the water. It might be the transom of a boat before doing your giant stride. The danger zone is the place where unconsciousness could further result in drowning.

    When I owned a Cis-Lunar Mk5P, I made little stickers for the side of my handset. When I owned a Megalodon rebreather, I used to say to myself, “Tanks on. ADV enabled. Safe PO2 in the loop.” With my PRISM2 rebreather, I review, “Tanks on. Setpoint enabled. Safe PO2 in the loop.” I always walk down a set of stairs with the loop out of my mouth and hanging around my neck, but if I ever fell in the water without fins and a mask, I know I could safely jump on the loop and recover from embarrassment.

  • Hidden Geography of Canada – Water Facts

    Roughly 8 per cent of Canada is covered by lakes, more than any other country in the world.

    The Brookings Institute, a U.S. think tank, found in 2007 that investing $26 billion in restoring Great Lakes ecosystems would create economic benefits in excess of $50 billion (Health Waters, Strong Economy: The Benefits of Restoring the Great Lakes Ecosystem).

  • Removing Your Reel from a Cave

    I habe posted another free informational video about how to properly remove a reel from a cave at the end of a dive. This video is for informational purposes and is not a substitution for proper training.

  • More baby turtles on Living Colours beach

     

    turtle rescue

     

    This time all the action happened in the early afternoon. I was just completing some paperwork with Johannes and Ira, who wanted to sign up for diving, when Rupert started shouting that there are baby turtles everywhere on the beach. We all rushed to see the hawksbill hatchlings. Again the tide timing was not ideal for the small vulnerable baby turtles to get out to the sea.

    The mother hawksbill turtle we saw a bit less than two months ago (blog post on March 17th 2016) had decided that laying her eggs behind the dive center was a good spot anyway. She almost got into trouble herself heading back to the sea when the tide had already gone out. Well, the crabs living in the mangroves would not have been a threat to the mum. But her offspring would not get the easiest start of their life.

    The nest had been high up on the dry part of the beach past some bushes and piles of leaves collected from the coconut trees. Some of the hatchlings had made it to the beach around the pile, but most of them were heading directly into this pile of leaves, from where they were struggling to find their way out to the beach.

    We started to collect all the hatchlings into baskets because the tide was still very low and the babies would have troubles getting trough the dense mangrove air roots on low tide. Unlucky day for the crabs living in the mangroves, since baby turtles would have been a delicacy treat for them.

    Within 10 minutes we had collected nearly 100 hatchlings into the baskets and rushed them along the beach trough the mangroves and waded into shoulder deep water to reach the deep wall drop off where we released them. What a unique moment to see all these tiny small turtles heading for the open ocean and wishing them safe start of life.

    Thank you Ira, Johannes, Rupert, Steven and all our staff who helped us to get these small hatchlings quickly and safely out to the sea!!!
