Two new species of the genus Cumella (Crustacea: Cumacea: Nannastacidae) associated with mesophotic reefs of Puerto Rico and St. Croix, Caribbean Sea

Two new species of genus Cumella G. O. Sars: Cumella solomoni and C. manolelii are described from mesophotic substrata of Puerto Rico and St. Croix (U.S. Virgin Islands), respectively. Similarities and dissimilarities with related species are discussed ...

U.S. Shrimp Market Integration

Recent supply shocks in the Gulf of Mexico—including hurricanes, the Deepwater Horizon oil spill, and the seasonal appearance of a large dead zone of low oxygen water (hypoxia)—have raised concerns about the economic viability of the U.S. shrimp fishery. The ability of U.S. shrimpers to mediate supply shocks through increased ...

Understanding differential patterns in coral reef recovery: chronic hydrodynamic disturbance as a limiting mechanism for coral colonization

Coral reefs are subject to numerous physical disturbances, and post-disturbance coral recovery potential depends on subsequent re-colonization of impacted habitat. We examined divergent recovery trajectories at 2 proximal reefs disturbed by ship groundings that resulted in clearly delineated areas of altered substrate. Post-disturbance measurements of coral recruitment, survival, and changes ...

Upregulation of hypoxia-inducible factor (HIF)-1α and HIF-2α mRNA levels in dragonet Callionymus valenciennei exposed to environmental hypoxia in Tokyo Bay

There is an urgent need to develop reliable biomarkers of environmental hypoxia exposure in marine organisms in order to assess the ecological impacts of the marked increase in coastal hypoxia worldwide. Full-length hypoxia-inducible factor HIF-1α and HIF-2α cDNAs were cloned and characterized from dragonet Callionymus valenciennei, a representative epibenthic teleost inhabiting ...

Urease Gene Sequences from Algae and Hetertrophic Bacteria in Axenic and Nonaxenic Phytoplankton Cultures

While urea has long been recognized as an important form of nitrogen in planktonic ecosystems, very little is known about how many or which phytoplankton and bacteria can use urea as a nitrogen source. We developed a method, targeting the gene encoding urease, for the direct detection and identification of ...

USGS/NOAA Workshop on Mycobacteriosis in Striped Bass, May 7-10, 2006, Annapolis, Maryland

As a Federal trust species, the well-being of the striped bass (Morone saxatilis) population along the Eastern Seaboard is of major concern to resource users. Striped bass are an extremely valuable commercial and recreational resource. As a principal piscivore in Chesapeake Bay, striped bass directly or indirectly interact with multiple ...

Using Acoustic Telemetry to Understand Connectivity of Gray’s Reef National Sanctuary to the U.S. Atlantic Coastal Ocean

This study analyzed nearly ten years of acoustic telemetry monitoring at Gray’s Reef National Marine Sanctuary, to understand its role in fish movements along the U.S. Atlantic coast. Designated in 1981, Gray’s Reef lies 17 miles off the coast of Georgia where water depths are ~60-70 feet and the habitat ...

Using bathymetric lidar to define nearshore benthic habitat complexity: Implications for management of reef fish assemblages in Hawaii

Habitat complexity plays a major role in determining the distribution and structure of fish assemblages in the aquatic environment. These locations are critical for ecosystem function and have significant implications for conservation and management. In this study, we evaluated the utility of remotely sensed lidar (light detection and ranging) data ...

Using Multiple Watershed Models to Predict Water, Nitrogen, and Phosphorus Discharges to the Patuxent Estuary

We analyzed an ensemble of watershed models that predict flow, nitrogen, and phosphorus discharges. The models differed in scope and complexity and used different input data, but all had been applied to evaluate human impacts on discharges to the Patuxent River or to the Chesapeake Bay. We compared predictions to ...

Using wildlife activity and antibiotic resistance analysis to model bacterial water quality in coastal ponds

Models that help predict fecal coliform bacteria (FCB) levels in environmental waters can be important tools for resource managers. In this study, we used animal activity along with antibiotic resistance analysis (ARA), land cover, and other variables to build models that predict bacteria levels in coastal ponds that discharge into ...

USVI Insular Shelf Accuracy Assessment Mission for Benthic Habitat Mapping Trip Report

NCCOS scientists conducted an independent assessment within the US Virgin Islands from January 30 to February 13, 2017 to evaluate the thematic accuracy of a draft benthic habitat map of the South Eastern Puerto Rican Shelf. Sites in the area ranged between 30?100 m in depth along the shelf, which ...

USVI St. Croix Hard Bottom Fish and Benthic Community Characterization Trip Report

In May 2012, NOAA led a multiagency mission to conduct a comprehensive assessment of fish and benthic communities at depths between 1-100 feet (0.5-30 m) around the island of St. Croix ...

Variability of biogeochemical processes and physical transport in a partially stratified estuary: a box-modeling analysis

Regional, seasonal, and interannual variations of freshwater inputs, biogeochemical transformations, and pelagic-benthic interactions were examined in the Patuxent River estuary. Monthly rates of net biogeochemical production (or consumption) and physical transport of carbon, oxygen, and nutrients were calculated for 6 estuarine regions using data-constrained salt- and water-balance computations (box model) ...

Variations in chemical speciation and reactivity of phosphorus between suspended-particles and surface-sediment in seasonal hypoxia-influenced Green Bay

Water, suspended-particles, and surface-sediment samples were collected from Green Bay, Lake Michigan, for the measurements of phosphorus (P) species, including dissolved/particulate-P, inorganic/organic-P, and five different forms of particulate-P, namely exchangeable- or labile-P (Ex-P), iron-bound-P (Fe-P), biogenic-apatite and/or CaCO3-associated-P (CFA-P), organic-P (Org-P) and detrital-apatite-P (Detr-P) to elucidate their reactivity and transformation ...

Visual Impact Assessment of Small Docks and Piers: Theory and Practice

From a manager’s perspective, oftentimes the publicly held concerns related to small docks and piers are not really related to the environment. They may be more related to visual impacts and aesthetic concerns, a sense of over-development of the shore, or simply change. While individuals may hold personal aesthetic values ...

Vulnerability of early life stage Northwest Atlantic forage fish to ocean acidification and low oxygen

Global oceans are undergoing acidification and deoxygenation, yet the concurrent effects of low oxygen and acidification on marine fish are unknown. This study quantified the separate and combined effects of low pH and low oxygen on 4 vital early life-history traits (time-to-hatch, hatching success, post-hatch survival, and growth) of 3 ...
