Home at last, oddly reflective, and thankful…

I arrived home early on Tuesday morning, after a month on the road. Bags filled with memories of a wonderful expedition that had its challenges, but which has already produced some positive results.

Steve and Cas conducted the final cleanup dive on the last day of work in the Bell Island Mine.

On Wednesday, a friend/colleague sent an email congratulating the #Minequest team on the “successful conclusion” of our project. I thanked her for the thought but pointed out that the project is far from concluded… in reality, it has just started. What we wrapped up last week was simply one small aspect of a rather large master plan… getting a circuit marked surveys and ready for visiting divers to follow.

What begins for the team now, having finished our underwater work (for the time-being), is to spread the word about the #bellislandmine and the historical significance or it and the four WWII wrecks sitting on the floor of the Tickle just a few kilometers from the mine entrance.

Another aspect is the ongoing educational commitments made on behalf of the project. Several members of the team toured local schools with a “show ‘n’ tell” immediately following the wrap in the mine. The reception from kids was “awesome” literally

Jill Heinerth also spearheaded a TED ED outreach bringing kids from around the globe into direct contact with explorers.

Stay tuned for more on this score as the year rolls on.

One other ongoing aspect is the impact made on divers participating in decompression research conducted during the project #drnealpollock #DAN #diveresearch. Several of the team, all experienced technical divers, and many teaching advanced decompression techniques, left Bell Island with a slightly altered, perhaps more circumspect view of #divesafety and the vagaries of decompression stress thanks to Dr. Neal Pollock and his research associate, Stefanie Martina from Divers Alert Network.

Now things are starting to get exciting

As the days tick down, preparations for Mine Quest are truly picking up speed. The process is somewhat mitigated because at least Newfoundland is not so remote that forgetting to pack some little but essential piece of hardware would probably not be a total disaster… not quite the same pressures as an expedition to jungle or the arctic; but pressure nevertheless.

The Explorers Club

Several great developments during the past few days. And one of the sweetest is that we got word that our team will be carrying an Explorers’ Club Flag.

These have been and continue to be part of the history of exploration. Explorers Club flags have been carried on hundreds of expeditions in the past 100 years, and represent one of the key principles of the Club’s mission: To engage in scientific exploration and share the results.

Explorers Club flags have been to both poles, to the highest peaks of the greatest mountain ranges, to the depths of the ocean, and to outer space. Now we get to take one for a trip to Bell Island, Newfoundland.

Also, the list of sponsors is growing… Our friends at Shearwater and Sub-Gravity are now supporting team members with products we know, trust, and are happy to depend on in the toughest conditions.Sub-Gravity expedition grade gear

And I would like to thank…

volunteers prepare surface staging area in Bell Island MineIn case you ever have to juggle “leadership”aspects of an underwater enterprise with many moving parts, and a whole bunch of so-called key personnel, each accomplished in their field. Here’s a secret tip to getting it off to a good start.

First and foremost, hope for quality support from the folks who really matter… the ones who do all the prep work for nothing more than the camaraderie, and a sandwich.

With that in place, the rest is a breeze.

As Jill Heinerth and I sit in the warm, coffee in hand, drawing up the framework of Mine Quest’s SOPs, a team of Golf cart for carrying supplies to water's edgefolks are working in the cool and damp putting the finishing touches to surface infrastructure in the mine. And from the pictures we seen, they have far exceeded expectations. I cannot imagine a better way to start a project, than to have these folks getting things ready for us.

Of course, it’s not all about Mine Quest. One of the project goals is to finally open Bell Island Mine as an adventure dive tourism destination, to complement and enhance the attraction of the four historic WWII shipwrecks resting a few hundred metres away on the bottom of Conception Bay South.

To be successful on that score, several pieces have to fit perfectly in place when we “go live” on February 15. However, thanks to the work of our support team, Bell Island Mine is starting to look like a really top-knotch dive destination!

Many thanks to all… but special gratitude to the folks wielding pickaxes, shovels, hammers and saws :

Ros Hurley, Jack Wood, Marcia and Mark McGowan, John Olivero, Nick Dawe, Kyle Morgan, Teresita and Des McCarthy, Ron Reid, and Bonnie and Tom Spracklin, Cecil Johnson, Holly Green, Debbie and Jillian Stanley, and others.

Not your average cave dive…

One of the first people to dive Bell Island Mine was a long-time friend and cave-diving buddy, Erik van Dorn. He was with us when we did a “proof of concept” dive in the summer of 2006.

We didn’t swim for long, just far enough to get some idea about the conditions. We laid a little line, found what looked like the remains of a small shed or stable, left a Newfoundland and Labrador provincial flag, and were back on the surface within 35 minutes.

He called me this morning to wish the team luck for our latest adventure, and he mentioned something that got me thinking about the differences and similarities between diving in a mine, in a cave and exploring the inside of a wreck.

Certainly it got me thinking about the first few dives we did. And the surprising number of artifacts we found… from downed tools and mine machinery, to graffiti written on mine walls with soot from miner’s lamps, and memorials for miners who lost their lives working the ore and trying to put bread on their family’s table.

That’s the sort of thing you simply don’t find in a cave.

 

Memorial to an absent team member

In February 2007, Joe Steffen suffered a massive embolism while exploring the Bell Island Mine, and passed away a few metres from the surface in the main shaft were today a memorial cross bears his name. Joe, a popular and respected figure in both the cave and wreck-diving communities, had an undiagnosed health issue, which was discovered during the medical examination following his death. The original exploration team’s medical officer (Dr. David Sawatzky), suggested that Joe’s passing would have been instantaneous, and probably caused by an ascent that would not have been an issue for a healthy diver.

The family Joe left behind, the original exploration team, the Bell Island Heritage Society, Bell Island Mine Museum, and the community of Bell Island, decided to continue the expedition back in 2007. We figured we owed it to Joe to push on.

This February, almost exactly on the ninth anniversary of Joe’s death, another team will be continuing the work begun in 2007. The hope remains that by opening the submerged area of the mine to guided tours similar to those conducted above the water line, a new group of visitors will have access to something truly unique in Canada.

With that in mind, and with the permission and support of Jennifer, Joey, Lindsey, and Linda, the members of the 2016 Mine Quest Team are dedicating this year’s expedition to Joe’s memory… RIP, mate: we think of you often.

 

The scope for exploration…

Bell island Mine Quest
The 2007 project put down approximately two kilometres of line shown in black.

One of the Bell Island Mine Quest team recently asked those of us who were part of the original expedition, how much of the network of passages is there left to explore… “Not the deep stuff running off for kilometers, but shallower stuff accessible to cave divers?”

Fair question and one that’s probably best illustrated by comparing the area we explored during our 2007 project, with a plan of the working area of the mine contained in the Bell Island Museum.

The “green map” shows the scope of our original exploration with the black lines representing gold line laid during our ten-day expedition.

The larger diagram below, shows that map overlaid on a partial map of the Bell Island Mine Workings that’s on display in the Bell Island Museum.

As you can see, the possibilities are almost limitless. For the record, the deepest 2007 dives went to approximately 55 metres / 178 feet, and lined approximately two kilometers (about 6,500 feet) of passages.

More construction around water level

The plans call for a boardwalk down to the water’s edge and an entry platform on the water’s surface so that divers can get into the water without silting things out.

Unlike the vertical or near vertical shafts found in many mines, the iron ore seam on Bell Island slopes at a roughly ten degree angle.

During past exploration, the dive teams getting into the water and beginning their dives had to wade for quite a distance before being able to float themselves and their kit. At the end of a “workday” the visibility in the water column from around three metres to the surface could be zero.

This slope, and the average height of the mine workings — approximately three metres/ten feet — makes for a slow descent and ascent… If you recall your High-school trigonometry and sine, cosine, tangent calculations, getting to a depth of 40 metres (130 feet and around the maximum for most of our planned exploration) requires a swim of approximately 230 metres / 750 feet.

 

Decompression Stress Study

Mine Quest Bell Island HeritageOne of the team goals for this February’s dives are to explore new passages and add to the two kilometers of line we laid during the 2007 project.

But we also want to “do some science.”

Of particular interest to any readers who dive or have friends and family who dive, is that members of our dive team will be part of a study monitoring decompression stress. Data will be collected from two-dimensional echo imaging ultrasound will be used to detect bubbles on both sides of the heart. Also, venous blood draws and buccal swabs will be collected to study stress responses. Study subjects will wear data loggers on all dives to capture their profiles, and information about the dive will be downloaded from PDCs and CCR controllers.

In addition, and in respect to ‘other markers’, changes in gene expression as a response to diving and epigenetic signatures related to repetitive diving will be collected.

Volunteers will have restricted activity for a two hour window after every dive, and will report for three minutes of scanning in every 20 minute time block during those two hours.
The research team will also collect onsite physical state and functional fitness measures before diving begins. Height, weight, skinfold thickness, pushups, situps, and range of motion cover most of the measures.

We hope that although the sample is small and the vastly diverse in age, gender, fitness level, and dive experience, useful information on decompression stress and its successful management will be the outcome of this aspect of the expedition.
