Building on the success of more than a century of research and education, BIOS is committed to addressing pressing global issues in oceanography, marine conservation, and ocean health. BIOS maintains a diverse portfolio of research activities that allow our knowledge to be shared both locally and internationally. We work to understand the ocean because if we better understand the source of human life, we might learn how to make human life better. That’s ocean science for human good. Scientists at BIOS are investigating many aspects of global coral health, including reef ecosystem functioning, coral reproduction, and factors that influence coral skeleton growth.

To facilitate ecological research CARMABI, originally short for the Caribbean Marine Biological Institute was founded in 1955 and has remained the largest field station in the Southern Caribbean. The field station still sits at its original, picturesque location at the opening of the Piscaderabay and reefs are found right in front of it. The number of visiting scientists has been increasing in recent years which prompted the construction of a new water-side building with lab facilities and dormitories for up to 30 people. Researchers or students that want to study Caribbean coral reefs, terrestrial systems or geology can now use these facilities for their science projects. The institute is currently visited by approx. 250 scientists a year for research purposes and by various universities for courses related to coral reef ecology. Willemstad, Curacao

Born of a passion for the sea and the wonders of tropical fish and coral reefs, the Coral World marine parks are the labor of love of a small number of enthusiasts. Touched with a steadfast belief that they could capture the excitement of the world below the tropical waters, and bring it to the awareness of the public at large, these enthusiasts have created a new phenomenon in marine observation. For more than three decades, Coral World has been the world leader in underwater viewing systems. The company has developed the only undersea observatories in the Western hemisphere and in the Red Sea. Two of the company's marine parks include the world's longest underwater acrylic tunnels. In addition, Coral World's tropical displays are recognized as the most beautiful in the world.

CoRIS is the Coral Reef Conservation Program's (CRCP) information portal that provides access to NOAA coral reef information and data products with emphasis on the U.S. states, territories and remote island areas. NOAA Coral Reef activities include coral reef mapping, monitoring and assessment; natural and socioeconomic research and modeling; outreach and education; and management and stewardship. Silver Spring, Maryland

For more than 20 years, NOAA CRW has utilized remote sensing, modeled and in situ data to observe, predict, and report to its users on the coral reef environment worldwide. CRW provides the only global early-warning system of coral reef ecosystem physical environmental changes. Its near real-time satellite products and modeled Outlook predictions have successfully and accurately monitored and predicted all major mass coral bleaching events observed globally since 1997, while also providing other critical information to users, especially during times of high oceanic heat stress. CRW's products help resource managers, scientists, decision makers (including elected officials), monitoring networks, and the public monitor climate impacts to reef ecosystems worldwide; better understand links between environmental conditions and ecosystem impacts; assess when reefs are vulnerable or resilient to climate change and its impacts (especially bleaching); and prepare and prioritize resources to implement timely, effective protective responses and adaptation actions (including restoration efforts), thereby improving the management and regulation of coral reefs in a warming world.

The "Reefmaker" of Walter Marine deployed its first artificial reef in 1986. Today it is the largest reef builder in the United States. The Reefmaker has deployed over 35,000 artificial reefs and owns four patents. Research has proven our artificial reef units outperform all others in natural substrate, complexity/rugosity, durability, size, production of fish, estuary substitute and wave attenuation. Over the years artificial reefs have evolved drastically. Today's artificial reef systems are designed for specific tasks such as: species habitat, wave attenuation, oyster restoration, estuary enhancement, coral reef repair, recreational diving, fishing reefs, fishery management, barriers to protect endangered habitat, snorkeling reefs and as integral parts of pier construction.
