What is Bahía Todos Santos Vigía?
Bahía Todos Santos Vigía — vigía: maritime lookout — is a maritime intelligence platform that monitors vessel activity in the Bahía de Todos Santos World Surfing Reserve — Mexico's first surf reserve, located in Ensenada, Baja California.
The platform ingests satellite and AIS vessel tracking data from Global Fishing Watch and processes it into structured intelligence outputs: vessel presence heatmaps, dark vessel detection events, and scored incursion records.
The system answers one question:
“Are vessels behaving in ways that threaten this protected area — and what is the evidence?”
The Monitoring Gap
In February 2026, the Ensenada community secured a landmark victory when the federal government canceled the El Sauzal industrial port expansion, protecting the Stacks and Tres Emes surf breaks from physical dredging.
But the victory exposed a structural gap: without persistent, data-driven monitoring, the legal protections risk becoming unenforceable on the water.
Anecdotal reports from local fishers and surfers document recurring incursions by industrial vessels that disable their Automatic Identification System (AIS) transponders — making themselves invisible to conventional tracking — while transiting through sensitive giant kelp (Macrocystis pyrifera) forests and restricted surf zones.
In the first 90 days of Bahía Todos Santos Vigía monitoring:
- —182 vessels identified operating in the bay over 90 days of monitoring, across passenger, cargo, and fishing vessel classes
- —111 cruise ships (passenger vessels) logged 5,990 hours in the bay — an average of 53+ hours per vessel
- —11 vessels detected by SAR satellite with no AIS identity on record — a 6% dark vessel rate against confirmed AIS traffic
- —3 dark vessel events scored HIGH severity based on recurrence and proximity to the WSR boundary
How the Platform Works
Vessel Presence Heatmap
The heatmap represents 90 days of AIS vessel presence data aggregated by grid cell. Use the layer controls (bottom-right of the map) to isolate specific vessel classes: cruise ships appear in white, cargo in orange, fishing in yellow. The heatmap always reflects the full 90-day monitoring window — it is not affected by the time range filter.
Dark Vessel Detections
Red markers indicate vessels detected by Synthetic Aperture Radar (SAR) satellite with no concurrent AIS broadcast. These vessels were physically present but deliberately invisible to maritime tracking systems. Source: GFW SAR Presence Dataset.
Incursion Scoring
Each dark vessel detection is scored 0–100 based on: detection source (SAR unmatched = highest), proximity to the WSR boundary, recency, and recurrence. Scores above 70 are classified HIGH severity.
Traffic Intelligence
The Intelligence panel aggregates 90 days of confirmed vessel activity into answerable questions: how many cruise ships called at Ensenada? Which flag states dominate the bay? Which vessels logged the most time near the reserve? This context makes anomalies meaningful — 11 dark vessel events stand out against a baseline of 253 identified vessels.
Why This Matters: The Blue Economy
A 2015 Surfonomics study commissioned by Save The Waves Coalition found that surf tourism generates between $746,000 and $969,000 annually for the local Ensenada economy — through lodging, food, transport, and equipment spending by visiting and local surfers.
That economy depends entirely on the health of the coastal environment. The same study found that 91% of visiting surfers said they would not return if significant environmental damage occurred.
Bahía Todos Santos Vigía exists to make environmental damage visible — and to give the community the evidence it needs to prevent it.
The World Surfing Reserve
On June 17, 2014, Bahía de Todos Santos became the sixth World Surfing Reserve designated globally by the Save The Waves Coalition, the first in Mexico. The designation protects five surf breaks and the coastal ecosystem that sustains them.
| Break | Conservation Goal |
|---|---|
| Salsipuedes | Guarantee public access |
| San Miguel | Maintain environmental quality of the arroyo and wave |
| 3M's | Improve public infrastructure and environmental quality |
| Stacks | Guarantee public access and improve coastal environmental quality |
| Killers / Isla Todos Santos | Maintain a pristine environment long-term |
