An integrated assessment of habitat quality of national estuarine research reserves in the southeastern United States

Multiple indicators of water quality, sediment quality, and biological condition were used to assess the status of ecological condition of National Estuarine Research Reserve System (NERRS) sites in North Carolina, South Carolina, and Georgia relative to a suite of corresponding ...

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 ...

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 ...

Benthic Characterization of Deep-Water Habitat in the Newly Expanded Areas of Cordell Bank and Greater Farallones National Marine Sanctuaries

A large area of the seafloor off northern California lies within the US National Marine Sanctuary System, but very little of the habitat has been explored and even less is characterized using visual survey techniques, especially deep-water habitats. Benthic surveys ...

Biotic resistance, disturbance, and mode of colonization impact the invasion of a widespread, introduced wetland grass

Disturbance and biotic resistance are important factors driving plant invasions, but how these factors interact for plants with different modes of colonization (i.e., sexual and asexual) is unclear. We evaluated factors influencing the invasion of nonnative Phragmites australis, which has ...

Characterization of deep coral and sponge communities in the Gulf of the Farallones National Marine Sanctuary: Rittenburg Bank, Cochrane Bank and the Farallon Escarpment

The purpose of the surveys was to groundtruth mapping data collected in 2011, and to characterize the seafloor biota, particularly corals and sponges, in order to support Essential Fish Habitat designations under Magnuson-Stevens Act (MSA) and other conservation and management ...

Characterization of the Mesophotic Benthic Habitat and Fish Assemblages from ROV Dives on Pulley Ridge and Tortugas during 2014 R/V Walton Smith Cruise

Three research cruises were conducted in 2012, 2013 and 2014 to the region of Pulley Ridge and Dry Tortugas to study and survey the mesophotic reef communities and fish populations. Pulley Ridge is the deepest known photosynthetic coral reef in ...

Choptank ecological assessment: digital atlas - baseline status report

The Choptank watershed was selected by NOAA as a Habitat Focus Area (HFA) for the Habitat Blueprint Program. As such, NOAA plans an integrated set of activities combining resources from multiple programs to leverage the full weight of its eff ...

Climate change and larval transport in the ocean: fractional effects from physical and physiological factors

Changes in larval import, export, and self‐seeding will affect the resilience of coral reef ecosystems. Climate change will alter the ocean currents that transport larvae and also increase sea surface temperatures (SST), hastening development, and shortening larval durations. Here, we ...

Climatic regulation of the neurotoxin domoic acid

Domoic acid is a potent neurotoxin produced by certain marine microalgae that can accumulate in the foodweb, posing a health threat to human seafood consumers and wildlife in coastal regions worldwide. Evidence of climatic regulation of domoic acid in shellfish ...
