This paper overviews several examples of important public health impacts by marine microbes and directs readers to the extensive literature germane to these maladies. These examples include three types of dinoflagellates (Gambierdiscus spp., Karenia brevis, and Alexandrium fundyense), BMAA-producing cyanobacteria, and infectious microbes. The dinoflagellates are responsible for ciguatera fish ...

This global assessment summarizes the current state of knowledge regarding documented and potential interactions of species listed under the ESA, such as sea turtles and marine mammals, and evaluates offshore longline mussel culture gear interactions as a case study. This assessment will strengthen the ability of NOAA and other regulatory ...

Shotgun mass spectrometry was used to detect proteins in the harmful alga, Aureococcus anophagefferens, and monitor their relative abundance across nutrient replete (control), phosphate-deficient (?P) and ?P refed with phosphate (P-refed) conditions. Spectral counting techniques identified differentially abundant proteins and demonstrated that under phosphate deficiency, A. anophagefferens increases proteins involved ...

The Bottlenose Dolphin Health and Risk Assessment (HERA) Project, initiated in 2003, is a collaborative effort between the National Ocean Service's Center for Coastal Environmental Health and Biomolecular Research and Harbor Branch Oceanographic Institution. This comprehensive, integrated, multi-disciplinary research project is designed to assess the health of Atlantic bottlenose dolphins ...

While 15N-labeled nitrogen (N) compounds have been used to quantify N uptake rates by plankton communities for decades, accurately ascribing those rates to individual populations or species has been a challenge. Here, we apply sorting flow cytometry combined with species-specific immuno-detection of a harmful alga, Aureococcus anophagefferens, to contrast the ...

Stratification and nutrient loading are two primary factors leading to hypoxia in coastal systems. However, where these factors are temporally correlated, it can be difficult to isolate and quantify their individual impacts. This study provides a novel solution to this problem by determining the effect of stratification based on its ...

We present water column thermal structure for two climatically different years: 2012, which experienced abnormally warm spring and summer air temperatures preceded by a relatively low ice winter and 2013, which experienced cooler than average spring and average summer air temperatures and preceded by average ice conditions. Mean bottom water ...

The tabular dataset is a product of household survey conducted in 2018. The sampling geography was a predefined coastal region of North and South Carolina adjacent to offshore wind development areas. The subject of the data collection was resident perceptions of local offshore wind energy development. Variables relate to place ...

Harmful blooms formed by species of the dinoflagellate Cochlodinium have caused massive fish kills and substantial economic losses in the Pacific Ocean. Recently, prominent blooms of Cochlodinium have occurred in central and southern California (2004–2008), and Cochlodinium cells are now routinely observed in microscopical analysis of algal assemblages from Californian ...

During 2013–2015, an outbreak of dolphin morbillivirus (DMV) occurred in the western North Atlantic, which resulted in the stranding of over 1,600 common bottlenose dolphins (Tursiops truncatus). There are currently five coastal and 10 bay, sound, and estuary dolphin stocks along the U.S. Atlantic coast, yet there is very limited ...

Toxic phytoplankton blooms threaten coastlines worldwide by diminishing beach quality and adversely affecting marine ecosystems and human health. The common diatom genus Pseudo-nitzschia consists of several species known to produce the neurotoxin domoic acid. Recent studies suggest that algal blooms dominated by Pseudo-nitzschia are increasing in frequency and duration owing ...

Gulf of Mexico hypoxia has received considerable scientific and policy attention because of its potential ecological and economic impacts and implications for agriculture within its massive watershed. A 2000 assessment concluded that increased nitrate load to the Gulf since the 1950s was the primary cause of large-scale hypoxia areas. More ...

Ecosystem-based fisheries management (EBFM) and ecosystem restoration are gaining momentum worldwide, including in U.S. waters of the Gulf of Mexico (GOM). Ecosystem models are valuable tools for informing EBFM and restoration activities. In this paper, we provide guidance and a roadmap for ecosystem modeling in the GOM region, with an ...

As global fisheries management shifts towards ecosystem-based management, responsible organizations and governments must also address the socio-economic impacts of this shift. This study evaluates potential impacts of such management shift with a case study of Pulley Ridge (PR), an ecologically rich area in the Gulf of Mexico, on fishermen and ...

Recruitment, or the entry, of young coral reef fishes into benthic populations is essential to population survival, but because larvae typically spend several weeks in the plankton away from the reef environment, understanding the entire process encompassing adult spawning, larval dispersal, and final settlement to the reef has been challenging ...

The combined effects of anthropogenic and biological CO2 inputs may lead to more rapid acidification in coastal waters compared to the open ocean. It is less clear, however, how redox reactions would contribute to acidification. Here we report estuarine acidification dynamics based on oxygen, hydrogen sulfide (H2S), pH, dissolved inorganic ...

The demand for marine sand resources is increasing in the United States, as coastal and offshore sands are commonly used for beach renourishment and barrier island restoration. The dredging of the Outer Continental Shelf (OCS), and sand shoals in particular, is likely to increase in the near future because nearshore ...

Seasonal hypoxia of the northern Gulf of Mexico has been observed for more than 25 years. It is generally accepted that the variation in the areal extent of hypoxia is determined by changes in nutrient addition from the Mississippi River. In this study, we investigate the statistical relation between the ...

A two day workshop was convened on February 2-3, 1998 in Charleston, SC with 20 invited experts in various areas of sea turtle research. The goal of this workshop was to review current information on sea turtles with respect to health and identify data gaps. The use of a suite ...

Globally, estuaries are considered important CO2 sources to the atmosphere. However, estuarine water carbonate chemistry and CO2 flux studies have focused on temperate and high latitude regions, leaving a significant data gap in subtropical estuaries. In this study, we examined water column carbonate system and air–water CO2 flux in the ...
