Friends share stories of diving beneath the ice

Brad Grecula could not see anything in the pitch-black water. Very slowly, something came into focus before him.

Grecula was looking at the Hopkins/Minnetonka shipwreck, which was once part of a fleet of six streetcar boats that transported people around Lake Minnetonka in the early 1900s.

When her sister boats were being dismantled and sunk in 1925, Capt. George Hopkins purchased it, renamed it Minnetonka and operated it as an excursion boat until 1949. At that time, it was sunk near her sisters north of Big Island. The state recognizes it as an archeological site, according to Maritime Heritage Minnesota.

As an outline of the wreck appeared before him, Grecula was sure it was the Hopkins/Minnetonka. After all, he and his friends had a GPS location on the shipwreck as they drove through a dense fog over the frozen lake, but diving through pitch-black water can mess with your mind.

“Your imagination can run away from you when you’re down there,” Brian Dahl said.

Divers going so deep that sunlight does not reach them can attest to what Grecula and Dahl are saying. What makes their tales even more harrowing is the only way they can escape the water is through a small hole in a thick sheet of ice.

Ice diving can be a deadly recreational activity if you are not properly trained and do not take the safety precautions seriously.

MyFox Twin Cities reported a story two years ago of a pair of ice fishermen hooking a scuba diver. The story had some comical elements to it because the fishermen thought they caught a big one. The diver was unharmed and offered a couple of beers as a peace offering, the fishermen told Fox news.

Dahl of Andover, Grecula of East Bethel, Art Gullette of Andover, John Oliver of Isanti and Nate Putbrese of Cambridge know this diver and this story was no laughing matter because several safety measures were not followed, they later learned. Ice divers are a fairly tight-knit group in Minnesota because there are so few of them, Gullette said.

The Professional Association of Diving Instructors is the not the only diving certification organization, but is the largest by far, said PADI spokesperson Bridget Evans. Over the last five years, more than 1,700 PADI ice diver certifications were earned throughout the whole U.S. In 2012, only 11.3 percent of all PADI certifications earned were for ice diving.

Mitigating the dangers

There are many safety measures to check off before going on an ice dive. The obvious first step is to make sure the ice is thick enough on which to drive a vehicle. Once on the site, they usually have a chainsaw to cut a triangle hole in the ice. They can cut a square, but a triangle takes less effort to cut because it has one less side.

They must be attached to a rope so they have an easier time finding the ice hole. Another step that can be taken is to clear snow in the shape of an arrow. Sunlight will highlight the arrow and give divers a bearing.

The most ideal situation is to have one person diving and another person on the ice in their gear in case the diver has to be rescued. There should be at least one and preferably two tenders in case both are in the water.

Ice diving is such a challenge that Dahl said PADI recommends a person have at least 50 dives before they can be trained.

According to Dahl, one of the most important traits he picked up from ice diving is the ability to remain calm and problem solve in tense situations.

A saying that stuck with Oliver is, “technical diving is the only sport where you can kill yourself and have half-an-hour to think about it.”

Gullette said this can be true of any type of diving, but the more logistically challenging the dive, the more true this is. There is a large difference between recreational and technical diving, he said.

Scuba diving in a river is beyond the level of most ice divers because “the current can take you into no-man’s land where there is no exit hole,” Oliver said. A second exit hole is a must for river ice dives, Gullette said.

If anybody feels nervous, a dive is called off without question.

Each of them has a different standard for calling a dive, however. Gullette is probably the most cautious, while Putbrese is the risk taker, to the chagrin of Gullette.

“When Nate calls it, I check my pulse because I may already be dead,” Oliver said.

Dahl, Gullette, Oliver and Putbrese know what a search and rescue feels like from the other side because they used to be volunteers for the Isanti County Sheriff’s Office dive team.

Isanti County does not have the budget for all the equipment so much of it is the diver’s own gear, said Chief Deputy Bill Guenther of the Isanti County Sheriff’s Office. Two men with their own gear recently volunteered to be the county’s only two dive team members, he said.

Although they may give Gullette a hard time for being such a stickler for the rules, he is deeply respected.

“I’ve done a fair amount of training through other instructors, but Art is hands-down the most thorough,” Oliver said. “It’s not that he wants to keep you there for an extra two hours. He wants to make sure you’re absorbing what he’s trying to tell you. I’ve told him before, when my daughter gets certified, he’s the one that’s going to do it.”

Some wild tales

Gullette first tried ice diving in 1975 and he swore he would never do it again, but he decided to give it a try when he met Putbrese in 2004.

“Nate and I have an interesting relationship. I keep Nate alive. He keeps pushing my comfort zone and envelope and keeping it fun,” Gullette said.

While they gave Putbrese some grief, Dahl was quick to note that Putbrese is very experienced and “dive smart.”

Dahl met Gullette through work at the Minnesota Department of Corrections and started diving around 2005. Oliver started ice diving in 2008 or 2009 just a year or two after celebrating his 40th birthday.

The four of them soon connected with Grecula, who began diving shortly after he graduated from high school in 2008. “Shortly after high school in 2008? Why do we let him hang out with us?” Dahl said while they all chuckled.

Their schedules do not always allow the five of them time to get together when they are not diving, but when they got together for an interview at Gullette’s Andover home, there was a lot of reminiscing, laughs and some head shaking.

One story Gullette really wanted to tell was the first time that Oliver was the unexpected rope tender on the surface. Oliver was still new to ice diving, so Gullette was training him on rope tending. Gullette was diving and Putbrese was supervising him on the ice.

Gullette suddenly came up to the surface all excited, telling them he found a wreck and giving them the coordinates so they knew where he was going. When he was surveying the wrecked boat, he looked to his left to see Putbrese swimming up to him. It turns out that Oliver was tending them both, which really made Gullette mad at Putbrese.

Another interesting tale was about a fisherman throwing his wedding ring down his ice hole on Mille Lacs Lake. The Isanti County dive team happened to be training in the area and Putbrese volunteered to recover the ring and, of course, document it.

Putbrese taped his descent and recovery of the ring and posted it on YouTube. Search “Nate Putbrese” to find his YouTube channel and the video. When he sees the ring, you hear him gurgling “my precious” in homage to the character Gollum from J.R.R. Tolkien’s “The Hobbit” and the “Lord of the Rings” trilogy.

Then there are the stories of Putbrese pushing the envelope. One time Gullette got out of the truck and walked to shore with his cell phone in hand and watched as Putbrese gunned the truck across the ice.

Oliver said Putbrese has graduated from “rock, paper scissors” to flipping a coin to determine if they should walk or drive across the ice. He will often throw these coins in the water to make a sacrifice to “the lake gods” and to see how long the coins are visible.

Arctic diving training 'a bit of a mind mess'

Diving into the darkness under one metre of ice is a lesson in panic.

One out of 10 experienced divers get to the Canadian North and can’t hack it. They come back to the surface, take off their mask and say never again, said Sgt. Scott Campbell, who is supervising the Canadian Forces dive team.

“You can imagine, it’s a bit of a mind mess,” he said, standing near the two-metre hole cut with chainsaws through the ice of Long Lake near Yellowknife.

“These guys are used to diving in open water. If there’s an emergency, you can shoot to the surface. Under the ice, it’s the prime condition for claustrophobia.”



Both army and navy divers are here this month as part of Arctic Ram, a northern training exercise lead by Edmonton-based army troops. The army divers are all engineers who defused roadside bombs in the arid desert of Afghanistan. Now that the Canadians’ combat role in that war has ended, the engineers are upgrading their diving skills in the north, where their most likely task is recovering vehicles, rifles or any person that falls through the ice.

Master Cpl. Tyler Thom and navy diver Leading Seaman Sebastien Guay got a thumbs down from a dive supervisor and slipped under the water Wednesday morning to practice.

The lake is four metres deep and the bottom is full of silt that clouds the water as the divers skim over. All they can hear is their own breathing through a line that smells like rubber and connects them to the surface. Occasionally, their ears pick up muffled commands coming through the surface radio.

Guay runs an emergency drill underwater. He slips off his mask and breathing equipment and recoils against the flood of cold water up his nose. When he gets his backup tank connected, he returns to the surface to readjust.

The shock of the cold water is the biggest adjustment, Campbell said. “Your body just wants to stop breathing and shut down,” he said. “We prepare for that in case we have to do it in an emergency.”

“We try to train as realistically as possible,” said Master Seaman Keith Bruce, also supervising the dive. “It allows the individual to react like it’s second nature. Sort of like firefighters; if they get caught on fire they drop and roll.”

Guay submerges again, and the two divers set out, swimming face up and bodies horizontal along the ice to find the emergency holes.

Looking up, they can see the brightened lines of a pinwheel shovelled clear of snow beforehand, the 200-metre circle and spokes centring on the main dive hole to help orient the divers to the above-world.

To find the exit holes, they divers simply find the circle and follow the bright lines until they get to the hole.

Clear of snow that blocks the light, the water is bright, said Thom after the dive. “You can see people walking across the ice and in some places (where the ice is clear), you can see almost right to the sky.”

During this dive, Guay and Thom stay on a fixed compressed air line to the surface. If that line were to be severed, the divers would switch to breathing with the emergency air tanks on their backs. They are then trained to grab an ice screw clipped to their gear, and screw it into the bottom of the ice to hold themselves in place. The air would last them an hour or so as a backup diver searches for them through their trail of bubbles.

The army divers are all specialized members of 1 Combat Engineer Regiment, all in top physical condition and able to handle stressful tasks with a methodical approach. The navy troops are clearance divers, trained to dive to 300 metres and capable of fixing ships at anchor without putting them in dry dock.

In the north, if a diver is feeling claustrophobic or stressed, they are trained to stop swimming and put both hands on the bottom of the ice, Campbell said.

“Close your eyes. Count to your number. Collect your thoughts,” he said. “Think about your safety (measures) in place and trust your buddy.”

Similar advice applies to anyone who struggles with panic and anxiety, he added.

“It’s about exposure,” Campbell said. “Learn in an controlled environment and have a good coach beside you.

“Know your plan, practice your plan and stay calm.”

Ice Diving on Shipwrecks with an Airboat - St. Lawrence River, Ontario, Canada

Discovery Channels Daily Planet show aired on March 12, 2009 - showcasing Arctic Kingdom's ice diving on shipwrecks from an airboat in the St. Lawrence River, 1000 Islands region. The region is a shipwreck scuba divers mecca, but because of open water and ice, traditional boats and snowmobiles cannot access the shipwrecks and see them with 100' visibility. Arctic Kingdom's airboat can move over ice and water providing a safe vehicle to access hundreds of shipwrecks and dive on them when water visibility is at it's best.

Cold water dive heats up enthusiasm for scuba


Fraser Debney didn’t get cold feet for winter diving when his alternate air source froze open in the St. Lawrence River, forcing him to abort a Boxing Day dive at Cardinal Ontario. On January 2, he was back at it in the same river, this time at Morrisburg, exploring the lost villages that were submerged during the building of the St. Lawrence Seaway almost 60 years ago.

He was down 58 minutes with six other divers, visiting the submerged Lock 23, the houses and foundations left behind on the river bottom and the old Highway 2, now covered in silt but easily identified because no seaweeds grow along its ribbon-like path.

There were no equipment problems this time. Fraser had upgraded to a more environmentally sealed primary regulator designed for colder water temperatures than his former one. He said a lot of dive gear is designed for southern climates and while some will say it is cold-water ready, “cold to California is different than cold water in Canada.”

But the piece of equipment Fraser really was interested in testing was his dive suit. Unlike the other six divers, who wore dry suits (preferred for cold water because of their warmth), he was wearing a wetsuit. Beneath it, he wore a fine thermal type of underwear. It got wet, but it stayed warm in that layer between his body and the wetsuit.

Before they entered the water, a couple of his diving mates joked that he was making them feel cold, just seeing him in a wetsuit on a winter dive.

“One of the divers is a doctor and at the end of the dive he said he was absolutely amazed I did the entire dive,” said Fraser. “He was watching me under water.”
He felt cold for two or three minutes when he first got into the water but quickly got used to it. But cold water (its temperature that day was 30 degrees Fahrenheit) has the benefit of clarity. There was a lot to see.

“Some of the old locks were big ones. The railings were still there where people walked on the top of them. This one was 35 feet down but in some of the areas they were deeper, dredged out for bigger ships.”

The buildings from the old original power stations had been taken away but a lot of the machinery was still under water.

Earlier, on the Boxing Day dive, which involved four divers, two of them experienced similar freeze-up problems to Fraser’s, but not as quickly. They got to see some of the underwater sights at Cardinal. There, the attraction was the wreck of the Conestoga, a freighter carrying a cargo of wheat that burned and sank in the 1920s.

The dive site was chosen for its “large safety factor” (shallow water and the current is not strong). This is why the Conestoga wreck is the location of many training dives.

Now that he has determined his equipment can withstand cold water temperatures, Fraser may expand his winter diving experiences even further. He is contemplating taking an ice diving course.

Throwing cold water on winter dive doesn’t cool enthusiasm for scuba

Wearing dry suits on Long Island, New York in ...Image via Wikipedia


While Boxing Day shoppers were chasing hot bargains, Fraser Debney and three of his scuba diving friends were into something much colder – the frigid waters of the St. Lawrence River.

For Fraser, who is beginning his third year in the sport, the dive at Cardinal in Eastern Ontario was primarily to test his ability to withstand cold water without the gear normally used in such water temperatures.

“It gave me an opportunity to push the limits of my wetsuit,” said Fraser, who lives in Montreal. “The other three more experienced people had dry suits (preferred for cold-water dives because of their warmth).”

Fraser improvised by wearing a fine thermal type of underwear under his wetsuit. “I found that it works well. It gets wet but still stays warm in that layer (between the wetsuit/underwear and his body).”

He had no problem staying in the water for 25 minutes or more. Unfortunately, almost all that time was spent standing near shore helping the others with their gear because his alternate air source froze open as soon as he entered the water. “The air runs continually and there’s no way to shut it off.”

Fraser aborted his dive but the other three divers went down to the wreck of the Conestoga, a freighter carrying a cargo of wheat that burned and sank in the 1920s. Two of the divers experienced similar problems as Fraser did and had to surface. The fourth was fine.

The dive site was chosen for its “large safety factor.” The Conestoga wreck is the location of many training dives. It’s shallow (the ship is within 20 feet of the surface) and the current is not strong. A bonus in winter is that there are fewer particles in the cold water so visibility is better. This helps underwater photographers capture good wreck pictures.

On Boxing Day the river was especially cold (one degree Celsius), which contributed to the freezing problem. Fraser said a lot of dive gear is designed for southern climates, adding that some will say it is cold-water ready, “but cold to California is different than cold water in Canada.”

There is cold-water gear designed to withstand the conditions but it is more expensive. While Fraser found he could get by in cold water without a dry suit, he also learned the temperature limitations of his regulator. “My local dive shop is going to run an ice diving course and I was thinking of participating. Now I know my equipment would not sustain doing that course.”

Basics of Ice Diving

Ice divingImage by asbjorn.hansen via Flickr

Ice diving is the practice of diving under ice. It is one of the more dangerous forms of scuba diving because of the extreme temperatures and the fact that there is generally only 1 exit, in turn it requires special training. Different scuba diving agencies have different ideas on what type of diving ice diving is, PADI for instance refers to ice diving as a form of recreational diving while NAUI and others refer to ice diving as a form of technical diving.

There are some basic procedures which are taught during ice diving training, without going into detail some of these would include: determining whether any given area is safe for diving, how ice is formed, dive site preparation, safety drills and equipment requirements.

Other topics covered during training include: Emergency situation procedures where divers will learn how to react should they become displaced from their line tender, dealing with frozen air supplies and how to handle the impact of the underside of the ice during an unexpected or uncontrolled ascent. Unlike most forms of scuba diving where gearing up, debriefing and a boat ride is all that is required to reach your destination; Ice diving requires a lot more effort and preparation- Divers will seek an area of potential and conclude whether the area is suitable for diving and if the ice holds the right requirements to perform a dive, next the divers will, in many cases, have to shovel the area clear of snow to reach the bare ice, this is then followed by cutting a hole in the ice using either a chainsaw or an ice saw. The final steps typically involve organizing the line tenders and gearing up.

The line tender which is attached to each diver is an important safety item in ice diving, this is because without them, divers could easily become lost. Should a diver lose sight of the exit/entry point he is likely to become extremely disorientated and could eventually lead to being unable to return to the surface (this has been a common cause of death in ice diving in the past), this is especially the case when diving in an area of low visibility, where you are more likely to lose sight of the exit/entry hole.

The scuba equipment used when ice diving is typically similar to normal scuba diving, although dry suits tend to take priority over wetsuits... And gloves, hoods and boots are definitely mandatory. One addition would be the line tender which tends to fit over the divers body between the wetsuit and the BCD, allowing for divers to shed their equipment if needed during an emergency and remain attached to the line.

It is very important that divers have reliable gear which is known to withstand the temperatures they will be facing. Some items on the market just can't keep up and fail under the freezing temperatures, make sure you do proper research into what gear is reliable for ice diving. It is also very important that all divers use regulators and not rebreathers, the rebreather has been at the center of ice diving deaths in the past.

Ice diving is definitely not for the weak and ice divers will tell you that straight. You need to be able to think clearly under stressful conditions, you need to be determined and you need to understand the risks. Though for those already involved in ice diving, they can vouch for the unique atmosphere present under the endless ceiling of ice with only their line tender holding them back from the abyss. Ice diving during the winter months will also, in some locations allow for water visibility that surpasses the imagination.
