Environmental Conservation Efforts

Artificial Reef Program

The Miami-Dade County Artificial Reef Program, established in 1981, has been a major conservation initiative:

• Created 11 inshore and 17 offshore artificial reef sites
• Deployed nearly 50 large vessels, two retired oil platforms, thousands of tons of concrete and limestone, and surplus military tanks
• Regarded as the largest artificial reef program in Florida in terms of materials deployed

The program aims to:

1. Restore and enhance marine habitats
2. Support fisheries management
3. Increase recreational diving opportunities

Key Biscayne Special Management Zone

Established in 1990, this zone restricts the use of highly efficient fishing gear to:

• Limit potential impacts of unrestrained fishing pressure
• Maintain most recreational uses of the site

Environmentally-Friendly Practices

The artificial reef program adheres to strict guidelines:

• Uses only durable, stable, and environmentally safe materials (usually steel or concrete)
• Carefully selects placement areas conducive to reef-building organisms
• Mimics naturally occurring rock outcroppings to support marine life

Monitoring and Research

The program conducts ongoing monitoring and research:

• Uses SCUBA, sidescan sonar, and underwater video for assessments
• Studies economic and environmental impacts of artificial reefs
• Researches reef spacing, design, succession, and fish recruitment

Collaborative Efforts

The program collaborates with various stakeholders:

• Works with local governments, nonprofit organizations, and universities
• Holds annual regional workshops and a statewide summit every 5 years
• Partners with Florida Sea Grant for research and outreach

Capturing Memories at Army Tanks: Photography Tips

Equipment Preparation

• Camera Choice: Use a waterproof camera or housing for your DSLR or mirrorless camera. Compact underwater cameras can also yield great results.
• Lenses: A wide-angle lens is ideal for capturing the tanks and surrounding marine life in their entirety. If you have a macro lens, it can be useful for close-up shots of smaller creatures.

Camera Settings

• Aperture: Set your aperture to a smaller f-stop (like f/8 to f/11) to achieve greater depth of field, ensuring both the tanks and marine life are in focus.
• Shutter Speed: Use a faster shutter speed (1/125 sec or faster) to freeze motion, especially if you’re photographing active marine life.
• ISO: Adjust your ISO to compensate for lower light conditions underwater. Higher ISO settings (400-800) can help, but be mindful of noise.

Shooting Techniques

• Stabilization: To avoid camera shake, consider using a stabilizing device or holding your breath while taking the shot. If possible, brace yourself against a solid object underwater.
• Lighting: Natural light diminishes quickly underwater; consider using an external strobe or flash to illuminate your subjects and reduce backscatter.
• Polarizing Filters: These can help reduce glare from the water’s surface and enhance color saturation in your images.

Composition Tips

• Get Close: Move in closer to your subjects for more impactful images. Water can distort colors and details, so filling the frame with your subject is beneficial.
• Backgrounds: Use simple backgrounds to avoid distractions. The tanks themselves provide interesting textures that can enhance your composition.
• Angles and Perspectives: Experiment with different angles—shooting from below or above can create unique perspectives of the tanks and marine life.

Capturing Marine Life

• Patience and Timing: Wait for marine creatures to come into view. Observe their behavior for better chances of capturing dynamic shots.
• Burst Mode: Use burst mode to take multiple shots in quick succession, especially when photographing fast-moving fish or other wildlife.

Post-Dive Considerations

• Editing: After your dive, use photo editing software to enhance colors and contrast, which can often look washed out due to the water.
• Sharing Your Memories: Consider creating a photo album or sharing your best shots on social media platforms dedicated to diving photography.
