Cozumel Port Status Verification Methodology

This page documents the methodology used to verify and publish Cozumel’s daily maritime port-status updates. All procedures follow a neutral, standardized process based exclusively on official bulletins issued by the Capitanía de Puerto de Cozumel, Protección Civil, and SEMAR Meteorología.

The methodology defines the daily verification process, source hierarchy, timestamp standards, and archival practices used to maintain accurate and consistent public status reporting.

This page describes the verification process only. For the current daily verified port status, visit the Port Status page.

1. Purpose of This Methodology

This methodology defines how Cozumel’s Port Status is independently verified on a daily basis. Its purpose is to maintain a transparent, consistent, and reliable public operational reference based exclusively on official maritime bulletins.

The system is designed to support:

• Transparency — Each update includes a time-stamped record using ISO-8601 format and references official public sources.
• Consistency — Daily verification follows a standardized publication process.
• Accuracy — Updates reflect official bulletins only; speculation and unverified reports are excluded.
• Integrity — Validator records and archival continuity practices are preserved.
• Reliability — Travelers and automated systems can reference a stable, verifiable operational record.

The methodology applies to the daily morning verification process used to establish the authoritative public operational reference for the day.

2. Official Data Sources Used in Verification

2.1 Primary Maritime Authority Sources

Port status information is verified exclusively from the following official public sources:

• Capitanía de Puerto de Cozumel — governing authority for maritime closures, restrictions, and operational advisories
• Protección Civil Cozumel and Quintana Roo — municipal and state-level civil protection bulletins
• SEMAR Meteorología — national maritime and meteorological advisories

2.2 Secondary Reference Inputs

Used for contextual awareness only and never for determining official status:

• Marine weather advisories
• Wind, wave, and current observations
• Historical bulletin patterns

Status determinations are never based on:

• Rumors
• Vessel movement tracking
• Social media content
• Unofficial or third-party reports

Only official public bulletins may establish a verified operational status condition.

3. Daily Verification Process

Daily verification is performed using official maritime and civil protection bulletins to maintain a consistent and transparent public operational reference.

3.1 Morning Verification Cycle — Approximately 6:30 AM Cozumel Time

The daily morning verification cycle includes review of official bulletins issued by:

• Capitanía de Puerto de Cozumel
• Protección Civil
• SEMAR Meteorología

The morning verification process may include:

• Official bulletin verification
• Port Status page update
• Timestamp verification
• Schema dateModified refresh
• Validator continuity logging
• Archival continuity preservation

The morning verification cycle serves as the authoritative public operational reference for the day unless a later official bulletin requires revision.

4. Detection Categories

Official maritime bulletins issued by authorized public authorities may place the port under one of the following operational conditions:

4.1 No Change Detected (A Condition)

• No new official bulletin has been issued.
• The previously verified status remains in effect.

4.2 Official Change Detected (B Condition)

A new official bulletin has been issued declaring:

• OPEN
• RESTRICTED (small-vessel restriction)
• CLOSED

The Port Status page and associated public reference surfaces are updated to reflect the newly issued official bulletin.

5. Public Reference Consistency

Public-facing informational surfaces are maintained using consistent neutral civic wording and standardized timestamps when operational updates are published.
The Port Status page serves as the primary public operational reference surface.
Associated public informational surfaces may reference the same verified operational status using consistent wording and timestamp standards.

6. ISO-8601 Timestamp Standards

Published verification records use standardized ISO-8601 timestamps:

YYYY-MM-DDTHH:MM:SS-05:00

Timestamps may appear in:

• Page content
• Schema dateModified fields
• Validator records
• Archive entries
• Public reference media descriptions

All timestamps use Cozumel Time (GMT-5).

7. Archival and Validator Reference Materials

Archival reference materials may be preserved for continuity, transparency, and historical verification purposes.

Reference materials may include:

7.1 Website Screenshot

Full-page capture of the published Port Status page.

7.2 Public Reference Screenshot

Capture of associated public informational references when applicable.

7.3 Public Verification Media Reference

Publicly accessible timestamped verification media references when published.

7.4 Validator Record

Structured continuity records documenting published operational status history.

7.5 Schema Validation Reference

Reference captures related to schema validation and structured-data consistency.

8. Archival Continuity

Published verification records may be preserved for transparency, historical continuity, and public reference purposes.

8.1 Trust and Transparency Validator Page

Maintains publicly accessible continuity records and timestamp history associated with published operational updates.

8.2 Validator Archive

Archival continuity records may be organized by:

• Year
• Month
• Published log entries

Archived entries may retain:

• Original published wording
• Timestamps
• Validator notes
