A day without diving is like a day without sunshine!

  • Lord Strathcona

    The wreck of the Lord Strathcona leaves one speechless. It has become remarkable artificial reef. The anemones celebrate the fact that no men were lost on this ship. The crew was able to abandon ship and safely reach shore. Today the site has become incredible habitat and a colorful museum of war history. Wrecks in Newfoundland are well protected and today you can still see a radio on the upper deck, phonograph records and silverware inside the ship. Thanks to the conservation ethic, many more divers will be able to share in the beauty.

  • Beating the Winds

    June 20, 2016

    The solstice gives us the longest day of the year but we needed to start early to beat the howling winds that built through the day. Our first dive was on the Free French Vessel PLM27. It was sunk quickly and 12 crewmen were lost. The Uboat U-518 captained by K/L Friedrich Wissmann snuck away, escaping undetected beneath a corvette Drumheller and two Fairmile fast boats patrolling Conception Bay.

    This was the second attack in Conception Bay and locals thought a spy had been involved. The captain of the PLM was not onboard the night his ship was sunk and had recently sold his piano to a Bell Island local. People wondered whether his loyalties were genuine since the Germans were occupying France. Perhaps the Nazis had turned the captain?

    The second dive was on the Saganaga. This ship was sunk on September 4, 1942. U-513 captianed by Rolf Ruggerberg followed the Evelyn B into the Bell Island anchorage on the night of September 3 and waited quietly in 75 feet of water. In the morning it rose to periscope depth and sunk the Strathcona and the Saganaga. 29 crewmen, all form the Saganaga were killed while U-513 escaped on the surface.

    My diving partner Sandra Clopp was using a Hollis PRISM2 rebreather. The rebreather recirculates our exhaled breath and removes carbon dioxide. We inject small bursts of oxygen to maintain a safe breathing gas. The device has an exothermic reaction that keeps us a little warmer that we would otherwise be in the near freezing water.

  • Back to Bell Island

    Thirty-five knot winds kept us off the boat today, but we took the opportunity to take new team members over to Bell Island to the mine. We met our dear friends Ed, Bernie and Bonnie and had some coffee and sandwiches before heading into the mine for a tour. We saw the plans for the new museum building which has just begun raising funds. They will need a lot of community support to reach their goal. They’re knitting hats, offering tours and working hard to find creative fundraising solutions.

    It is hard to imagine the strength of the miners at Bell Island. They loaded 20 carts a day of 1.5 tons per cart before they were able to go home. On Fridays they tried to load 30 so they could go home early on Saturday and have one precious day at home before heading back to the mine Sunday night.

    We had traditional fish and chips with dressing and gravy at Dick’s on the Wharf and then went off the road to the Grebe’s Nest to do some dry caving and exploring of the original mines that were cut at sea level. The rocks are a little treacherous and seeing tons of shale pancaked on top of ancient tram rails and machinery was a little sobering. In the distance we watched a grounded iceberg and hope we can dive it when the winds calm down.

    It is good to be back here!

  • Solid State Oxygen Sensors

    M28-CPOD-RB-LOWAsk a rebreather diver what drives their rebreather and they will undoubtedly tell you, the oxygen sensors. These annually disposable devices are critical to creating a safe breathing loop and yet when not functioning properly can reduce a $10,000 investment in life support to a useless hulk of unusable equipment. Oxygen sensors are a crucial component, informing the rebreather control systems about the partial pressure of oxygen within the breathing loop. They notify the electronics package when solenoid should fire and send more life giving oxygen into a diver’s breathing loop and alert the computer system when too much oxygen could cause a toxicity seizure that might result in drowning.

    Oxygen sensors are galvanic fuel cells that were originally devised for applications within the medical and automotive industry. Inside these relatively inexpensive devices, a chemical reaction is produced when the potassium hydroxide in the cell comes into contact with oxygen. This creates an electric current between a lead anode and gold-plated cathode through a load resistance. The current produced is proportional to the concentration (partial pressure) of oxygen present on the cell’s membrane.

    The problem with using galvanic oxygen sensors within diving applications is that we treat them to very harsh conditions. They get exposed to great ranges in temperature, mechanical shock from transportation and they slowly degrade in a way that causes them fail from the top down in a rather unpredictable fashion. Worse yet, we calibrate oxygen sensors in pure oxygen at ambient pressure and then ask them provide reliable data at partial pressures up to 1.6 and beyond while getting wet inside a diver’s CCR. The distrust in electro-galvanic sensors is so great, that we put three or more in a rebreather so that voting logic can help to validate their readings or inform the diver when an abort is necessary.

    After 5 years of extensive R&D testing and design iterations, Poseidon Diving Systems AB of Sweden announced a revolution to the diving industry. They released the first solid state oxygen sensor at the TekDiveUSA Show in Miami in late April. This long-awaited breakthrough will undoubtedly change the diving industry by dramatically increasing the safety of rebreathers. This factory-calibrated sensor provides an accurate and highly reliable digital output meaning that it can be permanently installed in a rebreather. There will be no need for user calibration. They will not expire and will provide a dependable reading under the unique conditions of the diving environment.

    M28-CPOD-Sensor-LOWThe solid state sensor uses special luminescent dyes, which are excited with red light. This oxygen dependent glow is detected in the range of near infrared light (NIR). Optical filters read the color pigments on the membrane and with the help of a temperature sensor, reliably translate that information into a reading on the diver’s handset. Compared to today’s galvanic oxygen sensors, these new solid state sensors show unsurpassed shelf life, operational life time and calibration stability. “The diving community has waited for many years for a sensor like this and the Solid State Sensor is considered as one of the “holy grails” of diving”, says Jonas Brandt CEO, Poseidon Diving Systems AB.

    Poseidon paired their announcement with the release of their new M28 computer. This wrist mounted platform offers a robust new graphical interface that feels like the cockpit of an airplane, but more importantly provides the diver with a way to view maps, surface GPS tracking and photos through its 32 GB memory. Coupled with the new solid state sensor, it can be attached to the breathing loop of many rebreathers and provide reliable oxygen readout. Both technologies will be integrated into Poseidon’s current and future life support systems, but the good news is that it appears that the M28 will be available in June 2016 with the sensors following later in the year.

  • Why We Do It

    Carol daughter of Harold BickfordlPeople have often asked me why we explore places like the mine on Bell Island, Newfoundland. The project was named Expedition of the Year by the Royal Canadian Geographical Society, but it is not honor and glory that compels us to explore. For me it was totally personal.

    In 2013, my husband Robert McClellan and I bicycled across Canada sharing my film We Are Water in efforts to spread water literacy. When we neared the end of our ride, I phoned Rick Stanley who owned Ocean Quest Adventure Resort in Conception Bay South. Could we complete our ride at his business and home? Could he extend us the generosity of a warm bed at the end of a three month journey. Rick opened his arms wide, helped us arrange more outreach opportunities to tell our story of water conservation and introduced us to Newfoundland at the same time. It was the one corner of my country I knew very little about.

    I did not know Rick Stanley, other than by reputation, prior to that phone call. But as with most Newfoundlanders, he practically gave us the shirt off his back and welcomed us in to a wonderful new family. Rick put us in his Zodiac boat and drove us to Bell Island. He showed us the war memorial and told the story of the shipwrecks sunk by Uboats in the nearby harbor. He took us to the mine and described the economic hardships that the islanders had faced. He was a proud, strong and affable character whose personal convictions could not help but sweep you off your feet.

    StMichaelsSchoolGemma5643lI knew I needed to give back. The people of Newfoundland welcomed me into their homes and lives and now I want to share their story with others and give them more tools to develop their local economy. 15,000 people resided on Bell Island when the mine was fully operational. 3,000 strong souls remain today. Bell Islanders are a picture of what it means to be Canadian. When the mine closed, they struggled on. When the cod fishery collapsed, they helped each other prevail. Each time the economy fails this corner of our nation, they prove what being good neighbors is all about.

    I was recently contacted by a man named Paul. He wanted to gift a photo to his Mother-in-Law Carol, daughter of Harold Bickford who toiled in the mine. Did I have a suitable photo I could share with them that could help her remember her Dad and connect with his sense of place? Carol shared her new picture that is now proudly hung on the wall of her home. It gave me goosebumps. If we can help connect more people with their sense of place and share this gem with more Canadians and the world, then our mission is accomplished.
