The title slide introduces a presentation on reducing sediment plumes in the Arabian Gulf through the innovative use of microbubble screens. Its subtitle emphasizes protecting marine ecosystems from the environmental impacts caused by dredging activities.

Reducing Sediment Plumes in the Arabian Gulf Using Microbubble Screens

Protecting Marine Ecosystems from Dredging-Induced Environmental Impacts

Sediment plumes in the Arabian Gulf pose a significant threat to marine ecosystems by reducing water clarity and damaging biodiversity and fisheries. The slide introduces microbubble screens as an innovative, sustainable solution for containment, while providing an overview of the causes, impacts, and mitigation strategies.

Introduction

• Sediment plumes threaten Arabian Gulf marine ecosystems
• Plumes reduce water clarity, harming biodiversity and fisheries
• Microbubble screens offer innovative, sustainable containment solutions
• Overview: causes, impacts, and mitigation strategies explored

Sediment plumes arise from human activities like dredging, which disturbs the seabed and suspends sediments, as well as coastal development that boosts runoff and erosion. Natural processes such as wave-induced erosion and turbulence from shipping propellers also resuspend coastal materials, contributing to these plumes.

Causes of Sediment Plumes

• Dredging activities disturb seabed, suspending sediments
• Coastal development increases runoff and erosion
• Natural erosion from waves mobilizes coastal materials
• Shipping traffic propellers create turbulence, resuspending sediments

The slide highlights the environmental impacts of an unspecified activity, showing that habitat degradation from sediment plumes affects 30% of areas, while biodiversity loss in marine ecosystems reaches 25%. Additionally, it reports an annual economic loss of $2 billion to fisheries and tourism.

Microbubble Screens Technology involves injecting tiny air bubbles into water to create dynamic barriers that generate upward currents, deflecting suspended sediments from sensitive areas and minimizing environmental impact in the Arabian Gulf. Air is injected through perforated seabed pipes to form a continuous bubble curtain, which traps and redirects sediment plumes during dredging, containing them within a defined zone for effective mitigation.

The slide outlines key challenges and limitations in marine bubble technology, including bubble stability amid strong ocean currents and the high costs associated with deployment and installation. It also highlights the need for ongoing maintenance and monitoring, as well as difficulties in integrating the system with existing marine operations.

Challenges and Limitations

• Bubble stability in strong ocean currents
• High deployment and installation costs
• Ongoing maintenance and monitoring needs
• Integration with existing marine operations

Microbubble screens are highlighted as an effective solution to reduce sediment plumes, safeguard marine ecosystems, and promote sustainable coastal management in the Arabian Gulf. The slide urges innovation for a clearer future and calls for immediate adoption of this technology to protect coasts, under the subtitle "Join the movement for Gulf sustainability."

Conclusion

Microbubble screens reduce sediment plumes, protect marine ecosystems, and enable sustainable coastal management in the Arabian Gulf.

Closing: Innovate for a clearer future.

Call to Action: Adopt microbubble technology now to safeguard our coasts.

Join the movement for Gulf sustainability.
