Uncovering the Hidden Reefs of Marine Park Bay, Tioman

Project Background

Between Tekek Jetty and ABC Jetty lies Marine Park Jetty, a relatively calm site known for its low visibility. Below, however, divers have discovered a field of sunken wrecks. These wrecks vary in condition, with some still connected by lines, while others appear isolated. Recently, a deep dive (28m) led by Zicong uncovered a massive pile of tires, organized in an orderly and densely packed formation. This surprising find raised questions about the history and purpose of the artificial
structures in the bay.

The use of tires as artificial reefs in Malaysia dates back to the 1970s and 1980s, driven by a desire to revitalize marine ecosystems and support fisheries. Despite good intentions, these projects often lacked scientific oversight. By 1995, the practice was banned due to the ecological damage associated with tire leaching and structural instability. Yet, no public record can be found for the large tire reef found in Marine Park.

This project aims to systematically explore, map, and document these underwater structures, uncovering their origins and assessing their current ecological impact.

Project Objectives

Map all known and newly discovered wrecks and underwaterstructures.
Create a site map indicating the locations, depth, and orientation of wrecks, tire piles, and deep reefs.
Use photogrammetry to generate 3D models of key structures.
Document and analyze biodiversity associated with each site.
Investigate the historical origin of the tire reef.

Mapping

Conduct detailed underwater surveys using compass bearings and depth measurements.
Chart all wrecks, reefs, and tire piles.
Apply photogrammetry for high-resolution 3D modeling.

Historical Research

Review archival materials and marine park records.
Interview local residents, dive operators, and authorities.

Environmental Survey

Record marine life presence and diversity at each site.
Document coral growth and fish populations.
Assess any signs of degradation or pollution from artificial structures.
