Exploring the DEEP: An Oceanarium Complex
The Oceanarium Complex at Sonadia Island, Cox’s Bazar, represents a pioneering approach to sustainable tourism in Bangladesh. Designed as part of a 980-acre eco-tourism vision, the 720-acre oceanarium
Introduction
Marine ecosystems are under constant threat due to pollution, overfishing, and climate change. Sonadia Island, with its unique ecosystem of turtles, red crabs, oysters, and historically valuable pink pearls, highlights both the fragility and richness of Bangladesh’s coastal biodiversity. Despite its natural wealth, the island suffers from inadequate infrastructure in healthcare and education. The Oceanarium Complex project aims to bridge this gap—acting as a platform for marine conservation, public education, research, and eco-friendly tourism while fostering economic resilience.
Project Vision and Objectives
The project is founded on four core goals:
- Marine Conservation – Establishing safe habitats for endangered marine species and raising awareness about ecological threats.
- Education and Research – Offering a marine biology research center, museum, and interactive exhibits for both researchers and the public.
- Community Development – Providing local employment, skill-building opportunities, and improved infrastructure.
- Economic Growth – Enhancing tourism and attracting international visitors, thereby contributing to the national economy.
Site and Design Approach
Location: Sonadia Island, Moheshkhali, Cox’s Bazar Site Area: 720 acres (Oceanarium site: 50 acres; Build area: 6 acres)
The site was selected for its proximity to the Bay of Bengal, enabling direct access to seawater for the large-scale aquarium systems. Extensive site analysis, climate studies, and ecological research informed the design process.
Design Philosophy
The central design narrative, “Connecting to the Underwater World,” structures the visitor experience as a gradual descent into ocean depths—from the sunlight zone to twilight, midwater, and abyssal layers. This immersive journey highlights biodiversity across marine ecosystems, cultivating empathy for ocean life.
