M

y heart skips a beat as I descend

into the chocolate-brown water

at the entrance to the Bell

Island mines in Conception Bay,

Newfoundland. A freak winter

gale has washed more than 3

feet of brown runoff into the mines during the night.

Our floating dock is stuck to the ceiling, and the diver

prep area is submerged beneath an inflowing river of

melted snow. It’s bone-chillingly cold, the visibility is

low, and I am lugging a large camera, lights and strobes

to capture images in water that I hope will be clear a

few hundred feet into the submerged passages.

The Royal Canadian Geographical Society has honored

our project as its 2016 Expedition of the Year, recognizing

our efforts to reveal the unseen depths of Canadian

geography. The Explorers Club has granted Flag #80 to

our mission, likewise acknowledging the importance of

sharing the secret, submerged assets of Bell Island.

Few people know that Bell Island was attacked during

World War II. In 1942 German U-boats blitzed the

island twice in attempts to disrupt the flow of the high-

grade iron ore being extracted from the mines. Raiding

U-boats sunk the SS

Saganaga

, the SS

Lord Strathcona

,

the SS

Rose Castle

and the Free French vessel

PLM 27

,

and they blew up the loading wharf on Bell Island. In all,

70 men were killed, and the region’s inhabitants were

awakened to their precarious position on the front lines

of the Battle of the Atlantic.

The goals of our project are ambitious. We are

establishing a visual archive of the history that was

submerged when the first mine closed in 1949 and

the last mine closed in 1966. With no inventory of

mine assets, we’ll be the first to reveal the cultural

history that was abandoned when it became too

expensive to continue the extraction of ore. In addition

to documenting the mechanical and engineering

history of the mine, we will be collecting biological

samples from ferrous oxidizing bacterial colonies and

hydrogen sulfide pools for DNA analysis. For me the

greatest revelations of all will come from physiological

examinations conducted by a team of scientists led by

DAN® research director Neal Pollock, Ph.D.

INNER SPACE

After each dive we rush to stow our gear as quickly as

possible and move up the 650-foot slope to the public

museum area of Mine #2. Pollock and Stefanie Martina

have set up a makeshift lab where they are poised to poke,

prod and query our bodies and minds. I peel off a sweaty

heated drysuit undergarment and lay prone on a mattress

while Martina preps a cold ultrasound probe to place

onto my ribcage. She gently rotates the device to find her

landmark, and a miraculous image appears on the screen.

I watch my beating heart, the valves of which look like a

downward-swimming mermaid in a black void. Martina

doesn’t have to tell me that my mermaid is navigating

a field of bubbles on the right side of the heart. My

decompression stress is clearly visible as rogue white dots

that bounce off the walls and move upward on the screen.

The first time I see it I am slightly alarmed. I feel great,

but Martina informs me I am showing grade IIIb on the

scale of bubbles (0, I, II, IIIa, IIIb, IVa, IVb, IVc and V,

with 0 being no visible bubbles and V being a whiteout).

I assure her that I am an open book and am ready to

publicly share every detail of my results. The questions

begin pouring out of me: Have I been bubbling for my

last 7,000 dives? Is this happening after most or all of my

dives, or is it particular to these cold, physical dives? How

closely correlated are these bubbles with decompression

sickness (DCS)? Pollock is generous with his educational

offerings but careful to explain that these investigations are

anecdotal. We’re all guinea pigs in this world of technical

diving, trying to apply mathematical probabilities to an

infinite set of parameters encompassing bodies, plans and

diving history. We can’t conclude which of the myriad

factors were most important in leading to my bubbles

after so few dives — or even know if the bubbles might

cause long-term issues — but we can certainly try to

reduce stress in future dives in many ways.
