Canadian search team consider ‘winter dive’ to explore Erebus wreck

Published

Erebus

Could the wreck of the HMS Erebus reveal the fate of Franklin himself?

A Canadian search team who found one of the lost vessels of the ill-fated Franklin expedition are so eager to get back to their discovery they are considering a dive through the Arctic ice in the spring to get a closer look at the well-preserved wreck of HMS Erebus.

“We’re exploring that possibility as we’re very anxious to get back,” said Ryan Harris, a senior underwater archeologist for Parks Canada.

Searchers discovered British explorer Sir John Franklin’s reinforced 19th-century wooden warship in the Queen Maud Gulf back in September.

Erebus

HMS Erebus and HMS Terror, shown in the Illustrated London News published on May 24, 1845, left England that year under the command of Sir John Franklin and in the search of the Northwest Passage.

But winter was rapidly closing in across Nunavut, and after just 12 hours taking photos and video of the sunken British vessel, underwater archeologists had to pack up and sail out of the Arctic before freeze-up.

The search team has every intention of going back to the site next summer — along with continuing the quest to find the other lost Franklin expedition ship, the HMS Terror.

But if there’s a way to get back to Erebus sooner — and Harris certainly hopes there is — divers could be going through the ice next April in an attempt to unravel more of the mystery of what exactly happened to Franklin and his crew of 128 men as they tried to find the long-sought Northwest Passage.

“It’s not something we routinely do,” Harris says of what would be considered winter diving.

“It’s not particularly complex, but it would mean that we’d be diving with surface-supplied diving equipment, not scuba, for safety.”

They would also have to set up an ice camp and rely more on air support — whether it’s helicopters or Twin Otters. And the Parks Canada team would likely be working more closely with divers from the Royal Canadian Navy.

Lots of expertise

While winter diving to explore a shipwreck is rare, it’s not unprecedented.

Last spring, Jonathan Moore, one of the members of the Franklin search team, worked with the Navy at the Nunavut wreck site of the HMS Breadalbane.

Erebus

Canadian Armed Forces divers working on the sea ice near Gascoyne Inlet, Nunavut, spent six days in April 2014 using remotely operated underwater vehicles to capture footage from the merchant ship Breadalbane, which sank in the High Arctic in 1853.

HMS Breadalbane sank near Beechey Island in 1853 while trying to get supplies to others looking for Franklin’s lost expedition.

“The ice camp was set up by the navy, and their fleet diving unit deployed a remotely operated vehicle to get images and data on the Breadalbane at a depth of 90 metres, quite a challenging wreck site to work on, so yes, there’s definitely precedent,” Harris said.

“There’s certainly a lot going on in the Canadian Arctic, and we have a lot of expertise that we can tap into.”

One of the questions now is whether that technical expertise can tap into the kind of private-public sector partnership that helped find the Franklin ships.

“I’ll be in a listening mode and a position to offer help, but I think this is exciting for Parks Canada because they are really going to be able to build off navy capacity in this case,” says Jim Balsillie, the co-founder and former chairman of BlackBerry-maker Research in Motion who was heavily involved in the Franklin search.

Balsillie helped start the Arctic Research Foundation, which refitted a fishing boat now known as the Martin Bergmann research vessel, which assisted in the search.

Whether or how the foundation might support a winter dive hasn’t been determined, but Balsillie says he is ready for suggestions.

“We will respond to Parks’ lead and the navy’s request in any way, shape or form we can be of help,” says Balsillie, who considers the foundation’s involvement in the Franklin search a “multi-year, probably multi-decade” project.

Done responsibly

Harris also sees the exploration of the Erebus wreck as a multi-year project, and one that must be done responsibly and systematically.

“There’s still quite a bit of work to do there,” he says.

“What makes it kind of difficult is the wreck is covered with a blanket of kelp.

“You have to be there firsthand to be able to poke in under the kelp fronds that cover the upper deck to be able to identify some features.”

Still, what Harris has been able to see so far has left him spellbound by the potential to unravel some of the many questions that have hung over the ill-fated Franklin expedition since the mid-1800s.

“Every dive we made was just a discovery from beginning to end, and you could scarcely take it all in. Everywhere you looked there was something new and really quite remarkable.”

Now, underwater archeologists are reviewing the hundreds of photographs and a couple hours of video they were able to take in September.

They are carefully plotting and planning their next moves in investigating what Harris describes as a “rather complex structure” that is overall “quite remarkably well-preserved.”

One of the challenges is to determine how divers can get inside the wreck.

Erebus

John Geiger, president of the Royal Canadian Geographical Society, holds an iron fitting called a davit from a Royal Navy ship, the key piece of evidence that led to the discovery of HMS Erebus in Queen Maud Gulf.

“A couple of us had the opportunity to drop down between the exposed deck beams and have a look around, but we weren’t penetrating below the decks at all.

“We were just kind of having a look and that tells us there’s a lot of room inside the forward half of the ship,” says Harris.

“You could look forward and see the ship’s galley stove. You could see the forward hatchway going down into the hold.”

Among the questions, could Erebus reveal anything further about the fate of Franklin himself?

“You don’t know at this point. The potential is almost limitless,” says Harris, noting that preservation conditions on an Arctic shipwreck can be “astoundingly favourable to the survival of organic materials, even including paper.”

Maybe there will be journals from crewmen, with handwritten accounts sealed up tight in a satchel.

Will there be human remains? (None have been spotted so far.)

Will there be anything that helps settle the questions around whether lead poisoning or botulism played a significant role in the sad demise of Franklin’s men?

Erebus

Searchers wonder what clues HMS Erebus might offer around the fate of Sir John Franklin, who was at the helm of HMS Erebus when it left England in 1845 with HMS Terror amid great optimism that they could find the Northwest Passage and sail to China.

Will there be clues that reveal whether Erebus drifted on its own to where it was found, or whether it had been re-manned, after the ships that had been beset by ice for two years and abandoned in 1848 off King William Island?

Maybe there will be evidence that reveals what the men were trying to do if they did indeed re-man the ship and navigate it into the Queen Maud Gulf.

“Were they just trying to get closer to the mainland so they could proceed on foot? Did they still hold out a forlorn hope of one day navigating to the Beaufort Sea?” Harris wonders.

“Hopefully time will tell.”

Get moving with the new RAID DPV training programs

Published

on

The thrill of speeding through the water behind a diver propulsion vehicle (DPV) is an experience that really gets the blood racing. Using a DPV provides divers both immense fun and the means to achieve goals that would be impossible without their use.

RAID is proud to announce the new two-tier DPV training program with certifications for DPV and Advanced DPV.

Why DPV and why now?
Recreational and technical divers are using DPVs to access sites that would be difficult to reach and explore using traditional propulsion methods; to help propel large amounts of heavy equipment; to increase the safety of dives in areas of strong current; or just for the pure exhilaration of shooting through the water at speed and performing underwater acrobatics.

By extending your capabilities and extending your range, using a DPV opens new vistas for exploration and fun.

DPV
This certification option is aimed at the recreational diver who wishes to learn how to use a DPV to enhance their diving by using mainly natural navigation.

Advanced DPV
This certification option is available to anyone who is familiar with longhose configuration, has logged a minimum of 20 dives and is certified as Navigation specialty divers.

This certification option is aimed at the slightly more experienced diver with preexisting navigational training and diving on a single, twin or sidemount setup with a longhose. Although this level is slightly more challenging, the more advanced navigation exercises provide an important base for more complex types of DPV diving within a team.

PREREQUISITES
You must:

  • Be a minimum of 12 years old.
  • Be certified as RAID Open Water 20, Junior Open Water or equivalent.

Just visit www.diveRAID.com to put some extra dash into your dives.

Beers raise cash for ocean clean-up

Published

on

The Driftwood Spars Brewery, a pioneering microbrewery based on the North Cornwall coast, is donating a percentage of all profits from its Cove range of beers to Fathoms Free, a certified charity which actively cleans the ocean around the Cornish peninsula.

Each purchase of the small-batch, craft beers – there are four different canned beers in the Cove range – will help generate funds to purchase a remotely operated vehicle (ROV) and fund retrieval dives; every brew will raise the equivalent cost of a fully-funded dive. 

Fathoms Free is a Cornwall-based charity whose day-to-day mission involves dives from their fast-response specialist vessel to recover ghost fishing gear; abandoned nets, pots, angling equipment and other plastic causes severe damage to the marine environment and the death of countless seabirds, seals, dolphins and other sea life.

The campaign to raise funds for an ROV is a new initiative which will take the clean-up work to a new level; the highly manoeuvrable underwater vehicle will be used to scour the seabed, harbours and remote parts of the coastline for abandoned fishing gear and other marine litter.

Project Manager Natallia Paliakova from Fathoms Free said: “Apart from helping us locate ghost gear underwater, the ROV will also be capable of recording underwater video which is always great for raising awareness about marine pollution issues.”

She added: “We are really excited to be partnering with The Driftwood Spars Brewery and appreciate the proactive support of Mike and his team in bringing the purchase of an ROV a step closer to reality.”

Head Brewer Mike Mason personally approached the charity after their work was featured on the BBC 2 documentary, ‘Cornwall with Simon Reeve’.    

He said: “As a keen surfer I am only too aware of the problem of marine litter and had heard about Fathoms Free, but seeing them in action prompted me to find a way of contributing. The scale of the challenge is scary, but the determination of organisations like Fathoms Free is inspiring.”

The Driftwood Spars Brewery was founded in 2000 in Trevaunance Cove, St Agnes; the microbrewery is just a few steps away from it’s co-joined brewpub, The Driftwood Spars; both pub and brewery are well-regarded far beyond the Cornish cove they call home. 

You can hear the waves and taste the salt on the air from the door of both brewery and pub, and the rough seas along the rugged North coast often throw up discarded nets and other detritus; Louise Treseder, Landlady of The Driftwood Spars and a keen sea swimmer, often collects washed up ghost gear on her daily beach excursions.     

Louise commented: “This is a great partnership to support a cause close to our hearts – I know the money we raise will have a positive and lasting impact. The Cove range was inspired by our unique surroundings and the artwork – by local artist Jago Silver – reflects that. Now donations from each purchase will contribute towards the vital ocean clean-up taking place right on our doorstep.”

The Cove range can currently be purchased online here, and is available in good independent bottle shops in Cornwall.
