USGS Role in DEEP SEARCH: Deep Sea Exploration to Advance Research on Coral, Canyon, and Cold-seep Habitats
USGS scientists are collaborating with multiple agencies to provide the esssential foundation for understanding these deep-sea environments.
DISCOVRE: Diversity, Systematics and Connectivity of Vulnerable Reef Ecosystems
DISCOVRE (DIversity, Systematics and COnnectivity of Vulnerable Reef Ecosystems) is an integrated, multidisciplinary, international effort investigating the unique and fragile deep-sea coral environments from the microscopic level to the ecosystem level.
Microbial Processes on Reefs
The microbial community on coral reefs is generally underappreciated given the ubiquity, abundance, complexity, and formative role these prokaryotes serve in the metabolic and chemical processes on reefs. We use microbiological and metagenomic techniques to decipher the roles the microbial community are playing in processes such as coral disease, submarine groundwater discharge, calcification...

Coral Microbial Ecology
The coral microbial ecology group has an active research program identifying and characterizing the microbial associates of both tropical and cold-water (deep-sea) corals and their surrounding habitat. Current projects focus on coral disease dynamics, bacterial diversity, and using metagenomics to elucidate the functional roles of coral microbes.
DISCOVRE - Diversity, Systematics and Connectivity of Vulnerable Reef Ecosystems Project
This project uses amplicon sequencing, and functional microarrays to examine the microbiomes of several deep-sea coral species, with priority given to species that are also of interest to the population genetics group: Desmophyllum dianthus, Lophelia pertusa, Enallopsammia sp., and Acanthogorgia sp. The project also uses metagenomics to survey benthic habitats including coral mounds, cold...
Coral Reef Ecosystem Studies (CREST)
The specific objectives of this project are to identify and describe the processes that are important in determining rates of coral-reef construction. How quickly the skeletons of calcifying organisms accumulate to form massive barrier-reef structure is determined by processes of both construction (how fast organisms grow and reproduce) and destruction (how fast reefs break down by mechanical...

Photos of corals affected by black-band disease in the Florida Keys.
Coral Disease
We investigated coral disease processes and causes by characterizing microbial communities in diseased and healthy representatives of selected coral species both temporally and spatially by employing microarray technology. We tested the diagnostic potential of coral fluorescence for identifying disease-induced physiological stress.

Identifying mangrove-coral habitats in the Florida Keys
Coral reefs are degrading due to many synergistic stressors. Recently there have been a number of global reports of corals occupying mangrove habitats that provide a supportive environment or refugium for corals, sheltering them by reducing stressors such as oxidative light stress and low pH. This study used satellite imagery and manual ground-...
Kellogg, Christina A.; Moyer, Ryan P.; Jacobsen, Mary; Yates, Kimberly K. Assessing the water quality impacts of two Category-5 hurricanes on St. Thomas, Virgin Islands
Managing waterborne and water-related diseases is one of the most critical factors in the aftermath of hurricane-induced natural disasters. The goal of the study was to identify water-quality impairments in order to set the priorities for post-hurricane relief and to guide future decisions on disaster preparation and relief administration.

Jiang, Sunny; Han, Muyue; Chandrasekaran, Srikiran; Fang, Yingcong; Kellogg, Christina A. Physicochemical controls on zones of higher coral stress where Black Band Disease occurs at Mākua Reef, Kauaʻi, Hawaiʻi
Pervasive and sustained coral diseases contribute to the systemic degradation of reef ecosystems, however, to date an understanding of the physicochemical controls on a coral disease event is still largely lacking. Water circulation and residence times and submarine groundwater discharge all determine the degree to which reef organisms are exposed...

Background: Numerous studies have shown that bacteria form stable associations with host corals and have focused on identifying conserved “core microbiomes” of bacterial associates inferred to be serving key roles in the coral holobiont. Because studies tend to focus on only stony corals (order Scleractinia) or soft corals (order Alcyonacea), it...

Brendan; Buster, Noreen A.; Phillips, Ryan M.; Frometa, Janessy Canyons microbiology studies
Off the eastern coast of the United States, several deep canyons cut through the continental shelf, acting like funnels to move sediment from the shelf out to the deep seafloor. Exposed rock outcrops and ledges along the walls of these canyons provide important habitat for deepsea corals and sponges. Although a few scientific expeditions have...

USGS microbiome research
Microbiomes are the communities of microorganisms (for example, bacteria, viruses, and fungi) that live on, in, and around people, plants, animals, soil, water, and the atmosphere. Microbiomes are active in the functioning of diverse ecosystems, for instance, by influencing water quality, nutrient acquisition and stress tolerance in plants, and...
