Depth affects Algal Symbiont composition in Caribbean Coral

First of Four Articles on Research Findings Comparing Shallow and Mesophotic Coral Reefs NCCOS-funded researchers investigating the diversity of symbiotic algae (Symbiodinium spp.) associated with the coral Agaricia lamarcki in Puerto Rico and the U.S. Virgin Islands found the coral’s algal associations change with depth. Light-dependent corals form a mutually beneficial relationship (symbiosis) with the […]

Experts Shape the Future of Caribbean Coral Restoration Science and Practice

Adapted text from Tali Vardi Coral restoration scientists, practitioners, and resource managers gathered at the Workshop to Advance the Science and Practice of Caribbean Coral Restoration in Fort Lauderdale, FL last month to address the rapidly expanding and evolving role of active coral restoration in the management of coral reef ecosystems. The three-day meeting facilitated […]

NOAA Student Scholars Present Summer Research With NCCOS

Ten student undergraduate scholars, most with the NOAA Educational Partnership Program and Hollings Scholarship Program, are interning this summer with the National Centers for Coastal Ocean Science (NCCOS) in Silver Spring, MD, Oxford, MD, Beaufort, NC, and Charleston, SC. Their internship programs culminated with presentations by each scholar of their summer research at the Science and […]

NCCOS Leads Key Topics at International Coral Reef Symposium

This week, staff from the National Centers for Coastal Ocean Science (NCCOS) led special sessions and gave individual presentations at the 13th International Coral Reef Symposium in Honolulu, Hawaii. The symposium is one of the largest international gatherings that bring together researchers, managers, policy makers, non-governmental organizations, and the general public to share and discuss recent […]

Environmental Variables Influence Toxic Ciguatera Algae Growth and Distribution

A new study describes optimal growth conditions for several species and strains of the benthic marine dinoflagellate Gambierdiscus and highlights how these species and strains respond differently to varying levels of salinity, light, and temperature. These environmental factors, along with suitable seafloor habitat, predict the geographic distribution of Gambierdiscus. Gambierdiscus is a genus of tropical and subtropical […]

Can Mesophotic Coral Ecosystems Serve as Lifeboats for Shallow Reefs?

On May 24, 2016, the United Nations Environment Programme released a new report on mesophotic coral ecosystems (MCEs) during a coral reef media roundtable at the second session of the United Nations Environmental Assembly (UNEA-2) in Nairobi, Kenya. The document, Mesophotic Coral Ecosystems: A lifeboat for coral reefs?, edited by GRID-Arendal and NOAA, represents contributions […]

Toxic Algae and Their Seaweed Hosts May Predict Ciguatera Fish Poisoning

New research shows that different Caribbean species of Gambierdiscus—the microscopic marine algae most often associated with ciguatera fish poisoning (CFP)—demonstrate different growth and attachment behaviors with different coral reef seaweed hosts. The findings are helping researchers understand how ciguatoxin moves through the food web, information which, in turn, could be used to improve reef sampling and monitoring […]

New Book Highlights NCCOS Work Aiding USVI Marine Park Management

NCCOS research was recently featured in a new book, Ocean Solutions, Earth Solutions, published by Environmental Systems Research Incorporated (ESRI). The NCCOS chapter, “Linking Landscape Condition Impacts to Coral Reef Ecosystem Composition for the East End of Saint Croix,” highlights the effects of terrestrial impacts to near-shore marine environments. The research specifically addresses land-based sources of […]
