An oil spill from the grounded tanker Caroline Bezengi has spread across a protected marine reserve off the coast of Oman.

The leak threatens fragile ecosystems within a designated sanctuary, complicating conservation efforts in the region and raising concerns over the environmental impact of maritime accidents in protected waters.

The spill occurred in early June 2024 [3] near the Hallaniyat Islands. The oil has specifically affected Qibliyah Island, which sits within a protected marine reserve [1, 2]. The tanker ran into trouble and may have suffered an explosion, which caused a breach in the hull and released the oil [3].

Satellite imagery and reports indicate the resulting oil slick covers a significant area. The slick is estimated at approximately 150 square miles [1], which is nearly 400 square kilometres [3].

Local authorities and environmental monitors have been tracking the spread of the pollutants across the water. The Caroline Bezengi remained stranded as the oil continued to migrate toward the shores of the reserve [2].

Efforts to contain the spill are complicated by the geography of the Hallaniyat Islands. The breach of the hull has allowed a steady release of crude into the surrounding currents, pushing the slick further into the sanctuary [1].

This incident highlights the vulnerability of marine protected areas to shipping accidents. Because the spill occurred within a sanctuary designed to preserve biodiversity, the long-term ecological damage may be more severe than a spill in open waters, potentially impacting endangered species and the local fishing economy.
