Light Shed on Hawaiian Reef Fish Food Sources and Trophic Positions

NOAA-funded scientists studying the diets of 22 species of Hawaiian coral reef fish living at both shallow (0-30 meters) and mesophotic (30-150 meters) depths found that the food source differed for invertebrate-feeding and omnivorous fishes and remained the same for plankton-feeding fishes. Although the sources of food were different between shallow and mesophotic depths, the […]

NCCOS Hosts Deep-Sea Coral Identification Workshop

In July, the NCCOS Deep Coral Ecology Laboratory (DCEL) held a two-day workshop on the taxonomy and morphological identification of deep-sea corals. The workshop was held in conjunction with the Center for Coastal and Marine Ecosystems (CCME) annual meeting in Charleston, SC, and attended by graduate students from the University of Texas Rio Grande Valley […]

Socioeconomic Infographics for CNMI and USVI Coral Reefs Published

In support of the National Coral Reef Monitoring Plan (NCRMP), NOAA social scientists and their partners collect a variety of socioeconomic data in seven U.S. coral jurisdictions to track information on each jurisdiction’s population, social and economic structure, the impacts of society on coral reefs, and the impacts of coral management on communities. A snapshot […]

NOAA Conducts Seafloor Mapping and Exploration off Channel Islands

Fisheries and coastal zone managers depend on fine scale bathymetry and habitat maps for critical management decisions, yet within NOAA’s Channel Islands National Marine Sanctuary (CINMS), a large part of the seafloor remains un-mapped and unexplored. From April 26th to May 11th, teams from CINMS, the National Centers for Coastal Ocean Science, Office of Coast […]

Mesophotic Reefs in Southwest Puerto Rico Shaped by Sediment Movement

Sediment exerts a basic control on the character and distribution of both shallow and mesophotic coral ecosystems (MCEs). In a rare study focused on sediment dynamics of MCEs, NCCOS-supported scientists found that downslope bed-load transport from shallower reefs (by coral and calcareous algae) exceeds suspended-sediment accumulation and has important influence in shaping MCEs in southwest […]

Southeast Deep Coral Initiative: NOAA Multi-Year Effort to Study Deep-Sea Corals

A new NOAA report outlines the objectives and activities of the Southeast Deep Coral Initiative (SEDCI). The initiative is a coordinated, cross-line office effort that includes partners from NOAA Fisheries, Ocean and Atmospheric Research, and National Ocean Service; and aims to collect scientific information needed to manage deep-sea coral ecosystems across the Southeast U.S through […]

New Guidance for Standardized Deep-Sea Observations

A new NCCOS report analyzes the application of the Coastal and Marine Ecological Classification Standard (CMECS) in Deep-Sea benthic surveys in the Northeast Pacific. The CMECS is intended to unify habitat classification efforts, in order to allow for broader integration and comparison of data. Habitat classification is important because it helps to identify deep-sea corals, hydrocarbon seep communities, […]

Depth Affects Algal Symbiont Composition in Caribbean Coral

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 single-celled algae Symbiodinium, commonly known as zooxanthellae, which provide energy for the coral […]
