La Jolla Freedive Club — March 2026

La Jolla Ocean
Human Performance Center

A vision for research, competition, and training at the La Jolla Submarine Canyon — one of the only locations on the US mainland where world-class depth freediving, scientific research, and military water-competency training can converge in a single site.

The center's physical footprint is a single surface buoy. Its impact reaches from Camp Garibaldi's 8-year-old students to Naval Special Warfare candidates to AIDA athletes setting national depth records.

“Performance in the ocean starts from the inside out. Breath first. Calm first. Then the water.”
Why La Jolla — and Why Nowhere Else

No other location in North America — and arguably no location in the world — offers this convergence.

Shore-accessible ocean depth exceeding 100 meters. The world's leading freediving research lab. The world's premier military special operations water-training facility. A major research hospital with 24/7 hyperbaric emergency capability. The world's most prestigious oceanographic institution. All within walking distance of each other.

Stress-Tested Against Every Alternative

We checked. Nobody else has this.

Any single factor in this convergence can be found elsewhere. Deeper water exists. Warmer water exists. Research labs exist. Military bases exist. What cannot be found anywhere else is all of them at the same location.

Monterey Canyon
Has: Depth (unlimited)
Missing: Water is 50-55°F year-round. Monastery Beach entry is deadly. No freediving research. No military. 350 miles from NSW.
Hawaii (Big Island)
Has: Depth, warm water
Missing: No freediving physiology research program. No NSW (BUD/S is in Coronado). Rocky lava entries. Remote, expensive logistics.
Dean's Blue Hole, Bahamas
Has: 202m depth, competition venue
Missing: Zero research infrastructure. No university, hospital, or imaging. No military. Small island in the Bahamas.
Lake Berryessa, CA
Has: Existing US competition venue
Missing: Freshwater lake. Max 69m. No ocean, no marine environment, no military, no research relevance.

Safety Infrastructure

The tightest emergency response chain in world freediving.

Across the United States, hyperbaric chambers are increasingly turning away diving emergencies, with many of the nation's 1,500 facilities transitioning to wound care only. Divers in Florida, the country's most popular dive destination, sometimes face hour-long ambulance rides to reach an operational chamber.

This emergency infrastructure is not something that can be replicated at remote competition venues. At Dean's Blue Hole in the Bahamas, Vertical Blue operates on a small island with no hyperbaric chamber and limited hospital access. At international competition sites in Dahab, Egypt, or Dominica, emergency evacuation to a chamber can take hours. At the OHPC, the world's leading diving medicine research program and a 24/7 hyperbaric emergency facility are a single ambulance ride away — operated by the same team.

Emergency response chain

On-site
Emergency oxygen, ACLS-qualified medic, rescue boat — required by AIDA competition rules

Pillar 1

Scientific Research — the UCSD connection.

A 2025 review in the European Journal of Applied Physiology identified critical knowledge gaps across cardiovascular regulation, pulmonary injury, and neurological effects of deep apnea — concluding that meaningful progress requires study during actual dives, not simulated dry apnea. The OHPC eliminates this bottleneck entirely.

UCSD Division of Hyperbaric Medicine
Dept. of Emergency Medicine
Faculty: Dr. Ian Grover (Medical Director), Dr. Charlotte Sadler (Fellowship Director, chair of hyperbaric medicine steering committee), Dr. Elaine Yu (wilderness medicine, freediving lung ultrasound). Funded by DAN. Landmark SIPE studies on Navy SEAL candidates. 800+ citation foundational review paper.
SIPE Research
Swimming-Induced Pulmonary Edema
5% incidence in BUD/S candidates. Studied in collaboration with Naval Medical Center San Diego. The OHPC enables field replication with civilian and military populations.
Blackout Prevention
Shallow Water Blackout Mechanisms
Investigation of hypoxic blackout, loss of motor control, and cerebral hypoperfusion during actual deep-water breath-holds — not dry lab simulations.
Imaging
Pre/Post-Dive Assessment
UCSD Medical Center MRI, ultrasound, and CT available within minutes of actual 60-100m ocean dives. No other site offers this proximity.
Lung Ultrasound
Freediving-Induced Pulmonary Syndrome
Diagnosis via lung ultrasound — Dr. Elaine Yu's research on pulmonary barotrauma detection in breath-hold divers using point-of-care ultrasound in the field.
DCI Research
Decompression Illness in Breath-Hold Divers
Investigation of decompression-like symptoms in repetitive deep breath-hold diving — an emerging concern as competitive depths increase beyond 100m.
Longitudinal
Weekly Cohort
Trained freedivers who dive at the same site every week, with logged environmental conditions. The controlled field population most researchers spend months recruiting.
DAN Partnership
Divers Alert Network
DAN funds the UCSD Division of Hyperbaric Medicine and insures LJFC. The same network that studies diving injuries worldwide provides the insurance and the research infrastructure.
Pillar 3 — Who It Serves

From 8-year-olds to special operators.

The common thread: breath control, equalization, water composure, and the ability to manage physiological stress in an aquatic environment.

Naval Special Warfare
BUD/S breath-hold, drown-proofing, SIPE prevention. 15 min from the site.
Marine Recon / MARSOC
Amphibious reconnaissance, beach recon, maritime interdiction. Camp Pendleton, 40 min.
Coast Guard Rescue Swimmers
80% attrition rate. Water composure is the core skill freediving teaches.
Ocean Lifeguards
Deep-water rescue, surf hold-downs. JG program (ages 9-17) feeds Camp Garibaldi.
Big Wave Surfers
Hold-down survival at Blacks, Todos Santos, Mavericks. Breath-hold under turbulence.
Scientific Divers
Bubble-free observation. Scripps grad students studying canyon ecosystems.
Spearfishermen
Statistically highest risk for fatal shallow water blackout outside military training.
Camp Garibaldi Youth
Ages 8-16. Breath-first methodology. The ocean camp that starts from the inside out.
Veterans
Mammalian dive reflex activates vagal tone — measurable parasympathetic regulation, not wellness culture.
Adaptive Athletes
Challenged Athletes Foundation based in San Diego. La Jolla Shores' gentle entry = most accessible.
Underserved Youth
ODI (City Heights) and Outdoor Outreach partnerships. Scholarship spots for Camp Garibaldi.
University Students
UCSD — 40,000 students, 5 minutes from the site. Discover Freediving → lifelong pipeline.
Infrastructure

The permanent buoy — a single point on the canyon rim.

A single permanent surface marker buoy at 32.856746°N, 117.262603°W — anchored at approximately 50 meters depth, 500 meters offshore from La Jolla Shores. The buoy marks an existing subsurface freediving mooring line.

What it enables

  • Visible fixed reference point for diver safety
  • Competition line rigging for AIDA depth events
  • Research observation site for UCSD studies
  • Navigation reference reducing vessel-diver conflict

Regulatory pathway

  • US Coast Guard — PATON authorization (33 CFR Part 66)
  • Army Corps of Engineers — Section 10 permit
  • CA State Lands Commission — Submerged lands lease
  • CA Coastal Commission — CDP or exemption
  • CDFW — Marine Protected Area compatibility
  • City of San Diego / Marine Safety — Local coordination

The Story

In 1939, the first freediving club in America was founded in La Jolla, California.

Eighty-seven years later, the great-grandson of an Azorean whaler who settled in San Diego for tuna fishing is building something at the same spot on the same coastline: a permanent site where the science of how humans perform underwater is studied, where the training that keeps people alive in the ocean is developed and delivered, and where the sport that tests the limits of a single breath is advanced.

The La Jolla Submarine Canyon drops from the sandy shallows of La Jolla Shores to depths that challenge the world's best freedivers — and it does so within walking distance of the world's leading freediving research lab, the world's most prestigious oceanographic institution, and the training grounds of the world's most elite military divers.

No one has connected these pieces before. The Ocean Human Performance Center does.

It starts from the inside out.
