CCMI MISSION RESEARCHEDUCATIONOUTREACH “Sustaining biodiversity through research, education, and outreach”

CCMI’s Key Strategic Thrusts To become the premier marine institute providing research and education facilities and programs based in the Caribbean. To be a leader in Caribbean community-based outreach programs promoting sustainable coral-reef ecosystems through better understanding of the existing reef environment. To establish programs that result in dialogue, strong relationships, and support from the Cayman Island’s Government and community. To develop capital and academic resources that fully fund and support our research and education programs. To develop a faculty that establishes the intellectual reputation of the institute.

Research Themes Connectivity: –Understand how reef organisms are connected at various depths and across geographic regions where social differences can be measured in relation to marine environmental conditions. Stress Response: –To better understand how coral reefs are stressed as a result of global climate change and human impacts.

CCMI Research Programs Climate Change & Coral Reef Stress. LAMP – Long-Term Assessment & Monitoring Program CCMI’s umbrella program to study our most threatened species and critical habitats in the Cayman Islands. Ecological Information- on the coral reef system (AGRRA, CARICOMP, LAMP Protocols) Environmental Information via NOAA-ICON Station – Instrumentation Measure effects of climate change on coral reefs Improves technological capacity for weather forecasting, storm prediction, tracking, and modeling.

Studying resiliency of our reefs since Importance: Knowing where juvenile corals are most likely coming from and where they are most likely going to settle is fundamental to coral regeneration.  Recruitment has not declined over all the years.  Juvenile growth rates per species  Juvenile survival over time  Adult population has stabilized loss since  Fish populations are not decreasing This work is illustrating that juvenile coral growth and that the community structure is similar to the overall adult population. We infer that the history of low fishing pressure and low growth of fleshy algae results in resiliency despite mortality. Research In Progress: Reef Resiliency 25cm & m 2 quadrants

Long Term Strategy Without Science- Everything is anecdotal Centre of Excellence for Climate Change and Environmental Stress Research on Coral Reefs; Coordinating a global effort with NOAA to understand the community changes in response to climatic variations; Build a resident research program at LCRC that also provides research staff to address adaptations to climate change; Build partnerships that will benefit from the NOAA instrumentation capability, CCCC, World Bank, OTEP.

Despite their isolation from heavy fishing, pollution, and other human induced stresses, the coral reefs around Little Cayman are still showing signs of degradation. Global Influence This is evidence that corals are being stressed by a large scale change in their environment, and that the lack of local impact may not aggravate the condition but it is not enough to neutralize the global influence.
