115 Meters Under the Surface — Danielle Laure’s Historic Dive in Fernando de Noronha

On the last day of October 2025, the deep blue of Fernando de Noronha witnessed an unprecedented feat.
Technical diver Danielle Laure (@uw.danielle) descended to 115 meters, marking the deepest autonomous dive ever performed by a Brazilian woman in open sea waters within the country(1).

The chosen site was the legendary dive point “Paredes”, revered among technical divers for its dramatic vertical formations, intense marine life, and an endless blue that disappears into infinity. A perfect stage for a challenge where technique meets courage.

The Path to the Bottom

This dive was not born from impulse — it was the result of months of meticulous planning, high-performance training, and the physiological and mental conditioning that only repeated exposure to extreme environments can consolidate.

During two weeks in Noronha, Dani conducted more than ten preparatory dives supported by the team at Mergulho Técnico (@mergulhotecnico) and Sea Paradise (@seaparadisefn), fine-tuning body, mind, and equipment for the descent.

Beyond depth itself, she had to face approx. 15 °C temperatures at the bottom, subtle currents, the increased density of saltwater, and variable visibility — factors that, combined, demand total mastery of buoyancy, consumption, gas control, equipment handling (including the camera inside the housing), lighting, and mental focus.

Two days before the main dive, on October 29, she reached 105 m, a decisive step to validate the gas mixture, physiological performance, and emotional stability.

“None of this would have been possible without the structure of Mergulho Técnico the group led by Johnny Franco — a team that believes in the impossible but never compromises on safety,” Dani says.
“The support and structure of Sea Paradise were also fundamental. What drives me is the passion for deep diving, for testing my limits, and coming back calm, aware, and grateful. I want to show that women can explore the frontiers of technical diving too.”

At 100 meters, pressure exceeds 11 atmospheres — an air bubble reduces to less than 1/11 of its original size. In this zone, every breath, movement, and decision must be executed with surgical precision.

Breathing Technology

For her historic dive, Dani used the Rebreather Kiss Sidewinder, a closed-circuit rebreather (CCR) that recycles exhaled gas, scrubs CO₂, and injects oxygen according to metabolic demand.

This technology allows for greater autonomy, exact PPO₂ control, and a drastic reduction in gas consumption — all critical in depths where the margin for error is nearly zero.

The gas configuration was carefully planned in advance by the dive team under the coordination of Johnny Franco (Technical Diving), a national reference in Trimix, Cave Diving, and CCR, and Fernando “Cabeça” (Sea Paradise), who leads simply the best diving operation in Fernando de Noronha.

Gas Mixes Used
Trimix 10/60 (10% O₂ / 60% He) — bottom gas, hypoxic, reduces narcosis and gas density
Trimix 16/35 — travel mix, controlled transition between depth and deco
Nitrox EN-50 and pure O₂ — decompression gases that optimize elimination of nitrogen

These mixtures kept respiratory gas density within safe limits (<6.5 g/L) and PPO₂ between 1.2 and 1.4 ATA — values within recommended technical protocols for extreme dives.
Sea Paradise’s logistical support, including a complete gas bank, precision analyzers, a dedicated boat, and a trained support team, ensured redundancy and safety at every stage.

The Dive

The operation was coordinated by Sea Paradise, with direct support from the technical team: Johnny, Chris, Richard, Bruno Tae, Miúdo, Fernando Cabeça, and Silvio.

The dive lasted 110 minutes total, with Safe Divers positioned from 21 m upward — a true underwater ballet of safety and synchronization.

The sea was calm, visibility excellent, and current minimal — perfect conditions for a record dive.

At 115 m, the world becomes silent and dense. Dani maintained stable PPO₂, respected her planned bottom time, and began her ascent with composure.

She passed through a cavern between 95 and 80 m, where daylight already filtered through the blue.
At 80 m, she returned to the guide line — the transition point from conquest to patience.

From there, nearly an hour and a half of decompression awaited — a meticulous, controlled return to the surface.

Training and Philosophy

“Technical diving is an ongoing journey,” says Johnny Franco, founder of Mergulho Técnico.
“Reaching 115 m is symbolic, but the true achievement is in the safety, control, and the ability to come back.
The important thing isn’t just going deep — it’s surfacing whole, with a clear mind and a heart ready to dream again.”

This philosophy reflects the essence of modern technical diving: responsibility, discipline, and passion for learning.
Mergulho Técnico, based in São Paulo, is one of the country’s leading references, offering training in Trimix, Caverns, CCR, Advanced Rescue, and Deep Expedition Planning.

More Than a Number

Dani’s dive is not only a technical milestone but a symbolic one.
In an environment still dominated by men at the highest levels, she proved that depth has no gender — it requires preparation, study, and courage.

Her return to the surface was slow, methodical, and beautiful: a choreography of gases, time, and calm.
When she finally emerged, the sun golden over Noronha, the team greeted her with applause, smiles, and a shared sense of accomplishment.

A Submerged Legacy

The name Danielle Laure (@uw.danielle) now joins the select list of divers who have explored the limits of the Brazilian sea with safety, technique, and humility.
She is officially the Brazilian woman who has dived the deepest in the sea in Brazil(1) — 115 meters of autonomy, precision, and passion.

More than a record, it was a declaration:
Even 115 meters below sea level, true depth lies in continuing to dream — and returning to tell the story.

(1) Based on research conducted for this edition, she is confirmed as the Brazilian woman who has reached the greatest depth in the sea within Brazil, in either open-circuit or closed-circuit scuba.
