An integrated assessment of the continued spread and potential impacts of the colonial ascidian, Didemnum sp. A, in U.S. waters

Didemnum sp. A is a colonial ascidian or “sea squirt” of unknown geographic origin. Colonies of Didemnum sp. A were first documented in U.S. waters in 1993 at Damariscotta River, Maine and San Francisco Bay, California. An alarming number of colonies have since been found at several locations in New ...

An integrated assessment of the introduction of lionfish (Pterois volitans/miles complex) to the western Atlantic Ocean

Lionfish (Pterois volitans/miles complex) are venomous coral reef fishes from the Indian and western Pacific oceans that are now found in the western Atlantic Ocean. Adult lionfish have been observed from Miami, Florida to Cape Hatteras, North Carolina, and juvenile lionfish have been observed off North Carolina, New York, and ...

An integrated environmental assessment of the St. Thomas East End Reserves (STEER)

The St. Thomas East End Reserves, or STEER, is a collection of Marine Reserves and Wildlife Sanctuaries (MRWS) located on the southeastern end of the island of St. Thomas, U.S. Virgin Islands. With an area of approximately 9.6 km2 , the STEER contains extensive mangroves and seagrass beds, along with ...

An introduction to NOAA’s National Database for Deep-Sea Corals and Sponges

NOAA's Deep Sea Coral Research and Technology Program (DSCRTP) is compiling a national database of the locations of deep-sea corals and sponges, beginning in U.S. waters. The DSCRTP will make this information accessible to resource managers, the scientific community, and the public over the World Wide Web. The database fulfills ...

An Investigation of Survey Technologies and Modeling Techniques for Improving Deepwater Surveys of Nonindigenous Species in the Northwestern Hawaiian Islands

This report examines survey technologies, with a focus on towed camera systems (TCSs), and modeling techniques which can increase nonindigenous species (NIS) detection and sampling efficiency in deepwater habitats of Northwestern Hawaiian Islands (NWHI); thus filling a critical data gap in present datasets. A pilot study conducted in 2008 at ...

An Oceanographic Characterization of the Olympic Coast National Marine Sanctuary and Pacific Northwest: Interpretive Summary of Ocean Climate and Regional Processes Through Satellite Remote Sensing

This summary represents the continuation of an ongoing collaboration with the Office of National Marine Sanctuaries (ONMS), Olympic Coast National Marine Sanctuary (OCNMS), and the National Centers for Coastal Ocean Science (NCCOS) Center for Coastal Monitoring and Assessment (CCMA), through a comprehensive regional oceanographic data synthesis and integration effort for ...

An unprecedented coastwide toxic algal bloom linked to anomalous ocean conditions

A coastwide bloom of the toxigenic diatom Pseudo-nitzschia in spring 2015 resulted in the largest recorded outbreak of the neurotoxin, domoic acid, along the North American west coast. Elevated toxins were measured in numerous stranded marine mammals and resulted in geographically extensive and prolonged closures of razor clam, rock crab, ...

Analyses of the complete chloroplast genome sequences of two members of the Pelagophyceae: Aureococcus anophagefferens CCMP1984 and Aureoumbra lagunensis CCMP1507

Heterokont members of the Pelagophyceae form the massive brown tides that have continually plagued the coastal regions of the eastern U.S. seaboard and the Gulf of Mexico. To gain a better understanding of the photosynthetic competence that may be linked to their success in forming massive blooms, we sequenced the ...

Analysis of sample frames and subsampling methods for reef fish surveys

The National Oceanic and Atmospheric Administration’s Biogeography Branch has conducted surveys of reef fish in the Caribbean since 1999. Surveys were initially undertaken to identify essential fish habitat, but later were used to characterize and monitor reef fish populations and benthic communities over time. The Branch’s goals are to develop ...

Application of the Coastal and Marine Ecological Classification Standard (CMECS) to Deep-Sea Benthic Surveys in the Northeast Pacific: Lessons from Field Tests in 2015

The Coastal and Marine Ecological Classification Standard (CMECS) is a comprehensive, standard terminology published in 2014. The standard is intended to unify habitat classification efforts, in order to allow for broader integration and comparison of data. The standard is well-developed, and has been implemented in some regions, but CMECS not ...

Applications of spatial autocorrelation analyses for marine aquaculture siting

Interest and growth in marine aquaculture are increasing around the world, and with it, advanced spatial planning approaches are needed to find suitable locations in an increasingly crowded ocean. Standard spatial planning approaches, such as a Multi-Criteria Decision Analysis (MCDA), may be challenging and time consuming to interpret in heavily ...

Aquatic invasive species transport via trailered boats: what is being moved, who is moving it, and what can be done?

Trailered boats have been implicated in the spread of aquatic invasive species. There has been, however, little empirical research on the type and quantity of aquatic invasive species being transported, nor on the efficacy of management interventions (e.g., inspection crews, boat washing). In a study of small-craft boats and trailers, ...

Archeolourinia shermani, a new genus and species of Louriniidae (Copepoda: Harpacticoida) from a Caribbean mesophotic zone

Mesophotic coral ecosystems (MCEs) are found on the insular and continental slopes of Caribbean islands and comprise mainly scleractinian corals, sponges and macroalgae. These species provide habitat for a highly diverse and specialized crustacean fauna. A new genus and species of the family Louriniidae is described from samples taken from ...

Assessing biophysical controls on Gulf of Mexico hypoxia through probabilistic modeling

A mechanistic model was developed to predict midsummer bottom-water dissolved oxygen (BWDO) concentration and hypoxic area on the Louisiana shelf of the northern Gulf of Mexico, USA (1985–2011). Because of its parsimonious formulation, the model possesses many of the benefits of simpler, more empirical models, in that it is computationally ...

Assessing movements of three buoy line types using DSTmilli loggers: Implications for entanglements of Bottlenose dolphins in the crab pot fishery

A study was conducted in October 2006 in the Charleston, South Carolina area to test the movements of three different buoy line types to determine which produced a preferred profile that could reduce the risk of dolphin entanglement. Tests on diamond-braided nylon commonly used in the crab pot fishery were ...

Assessment of crude oil and a dispersant in a simulated Spartina alterniflora salt marsh ecosystem

NOAA's Environmental Sensitivity Index (ESI) lists saltmarshes along the Atlantic and Gulf Coasts as the most vulnerable habitat to oil spills. As a result of the Deepwater Horizon offshore drilling rig accident, more that 200 million gallons of crude oil were released into the Gulf of Mexico, and more than ...

Assessment of dredged material created habitat in the South Atlantic Bight – Fernandina Beach Ocean Dredged Material Disposal Site (ODMDS)

The National Centers for Coastal Ocean Science (NCCOS) collaborated with EPA Region 4 Water Protection Division of Coastal and Marine Resources and Wetland Enforcement Section to assess Ocean Dredge Material Dump Sites (ODMDS) as essential fish habitat off the coast of Fernandina Beach, FL. The objectives of this project were ...

Assessment of Ecological Condition and Potential Stressor Impacts in Offshore Areas of Florida Keys National Marine Sanctuary

In June 2015, the NOAA National Centers for Coastal Ocean Science conducted an assessment of the status of ecological condition of unconsolidated, soft-bottom habitat and overlying waters at 30 sites from 11 – 99 m depth in targeted shelf areas of Florida Keys National Marine Sanctuary (FKNMS). All sampling was ...
