Protecting the Future of Cayman’s Coral Reefs; Dr Gretchen Goodbody-Gringley

While there are numerous local causes of coral loss (e.g., pollution, destructive fishing practices, etc.), the two most detrimental stressors currently impacting the survival of corals are bleaching caused by thermal stress and disease. As our ocean continues to warm and outbreaks of disease become more prevalent, it is critical to understand the capacity of organisms to adapt and/or acclimate to changing conditions and seek solutions to promote resilience and sustain biodiversity. Initiating a science-based restoration program in the Cayman Islands in 2011, CCMI has been and will continue to be a pioneer in the coral reef restoration arena. Current restoration empirical investigations coupled with available long-term ecosystem data at CCMI provides the basis for furthering knowledge of reef resilience. Dr. Goodbody-Gringley discusses results from our past restoration studies and presents a new outlook for development of resilient coral populations through advanced restoration techniques that will shape the future of coral reefs in the Cayman Islands.

Presented at the National Gallery of the Cayman Islands 10 November 2020.

Cuba’s Hidden Treasures: An Underwater Adventure to Gardens of the Queen Coral Reefs; Dr Amy Apprill, Woods Hole Oceanographic Institution

This talk will take you on an underwater adventure to the pristine coral reefs of Gardens of the Queen in southern Cuba. Learn about the unprecedented partnership between U.S. and Cuban scientists that studied these reefs and how we combined resources and training from our respective countries to present a holistic and technologically innovative view into this ‘crown jewel’ reef system of the northern Caribbean.

Dr. Amy Apprill leads the Microbial Ecology for Ocean Conservation research laboratory at the Woods Hole Oceanographic Institution. Her research examines the contribution of microorganisms to the health and ecology of sensitive animals and ecosystems of the ocean. Presented 30 September 2020

Two Decades of Resilience on the Reefs of Little Cayman; Dr Gretchen Goodbody-Gringley

Since 1999, researchers at CCMI have been monitoring the health of the coral reefs around Little Cayman Island by surveying various aspects of the community on an annual basis. Long-term monitoring studies such as this enable assessment of the resilience of the reef to changing conditions over time and also give a better understanding of the true impact of global climate change. Following the standardized protocol of the Atlantic and Gulf Rapid Reef Assessment (AGRRA), these surveys document patterns of local change over the last two decades and enable regional comparisons through the Healthy Reef Framework developed for evaluating the Mesoamerican Barrier Reef.

CCMI’s Director of Research, Dr Gretchen Goodbody-Gringley, shared findings about the change over time for coral cover, coral composition, algae, and fish density and biomass from CCMI’s 20 year data set of annual reef monitoring activity. She also discusses Stony Coral Tissue Loss Disease, which has recently been discovered on Grand Cayman. Presented 22 July 2020

Stop Whining! Life as an ocean ambassador; Ellen Cuylaerts

Ellen Cuylaerts shares her insights on how to act, practice what you preach and use your voice to contribute to constructive change. Ellen is a wildlife and underwater photographer and chooses to take images of subjects that are hard to encounter like harp seal pups, polar bears, orcas, beluga whales and sharks, to name a few. By telling the stories about their environment and the challenges they face, she raises awareness about the effect of climate change on arctic species, the cruel act of shark finning and keeping marine mammals in captivity.

During this seminar, Ellen will take you on a virtual trip and show you the stories behind the shots: how to get there, how to prepare, how to create the most chances to come home with a shot, and how to never give up!

Ellen Cuylaerts is an ocean advocate, underwater & wildlife photographer, explorer, and public speaker.  Presented 11 June 2020

Coral Health: from microbes to branches; Dr. Anya Brown

Healthy corals are critical for sustaining reefs. Corals are in a tightly coupled relationship between bacteria (like in your gut!), microscopic algae, and the coral animal itself. This seminar, presented by collaborative scientist Dr. Anya Brown, focused on trade-offs between types of coral growth, a coral disease outbreak, and what clues the microbes on corals tell us about their health.

Dr. Anya Brown is currently in the Ewel Postdoctoral Fellowship Program in Ecology and Environmental Science at the University of Florida. Presented 21 January 2020

Coral Reef Resillience and Refugia; Dr Gretchen Goodbody-Gringley

This presentation focused on current threats to coral reef systems and mechanisms to overcome them through changes to reproductive patterns, epigenetics, dispersal, morphology, and physiology, with specific attention to the potential for mesophotic reefs (deep below SCUBA depth limits) to serve as a refuge for future coral survival. Dr Goodbody-Gringley presented her current work on the deep reefs of Bermuda and attendees will see a part of the ecosystem that is unreachable using recreational diving.

Dr. Goodbody-Gringley is a Research Scientist at the Bermuda Institute of Ocean Science. Presented 25 April 2019

20 Year Surveys of Cayman Reefs; Dr Claire Dell

Dr Claire Dell presents on the Cayman Islands Reef Survey Report from 1999 – 2018. In July 2018, a team of six science divers and one boat captain from the Central Caribbean Marine Institute (CCMI) concluded surveys of 25 reefs across the three Cayman Islands (eight reefs in each of the Sister Islands and nine on Grand Cayman), the same reefs which CCMI had originally surveyed in 1999. The scientists used the same Atlantic & Gulf Rapid Reef Assessment (AGRRA) protocol as was used in the original 1999 survey, in order to have an accurate assessment of the change in reef health during this time. What did the scientists find in the most recent survey? How does that compare with what they found 20 years ago? Learn about the results of the survey – and what this means for the future of our coral reefs. Presented 28 February 2019
