The North Carolina Sentinel Site Cooperative (NCSSC) was established in 2012 as part of a National Oceanic and Atmospheric Administration (NOAA) effort to provide coastal communities and resource managers with information on the potential impacts of sea level rise on coastal habitats. The NCSSC utilizes a collaborative business model to bring together stakeholders, including ...

The Louisiana shelf, in the northern Gulf of Mexico, receives large amounts of freshwater and nutrients from the Mississippi–Atchafalaya river system. These river inputs contribute to widespread bottom-water hypoxia every summer. In this study, we use a physical–biogeochemical model that explicitly simulates oxygen sources and sinks on the Louisiana shelf ...

Numerical models can provide the needed information for understanding hypoxia and ensuring effective management, and this book provides a snapshot of representative modeling analyses of hypoxia and its effects. In this chapter, we used the modeling and analyses across the other 14 chapters to illustrate 8 themes that relate to ...

Multi-year nitrogen (N) and phosphorus (P) budgets were developed for the Patuxent River estuary, a seasonally stratified and moderately eutrophic tributary of Chesapeake Bay. Major inputs (point, diffuse, septic, and direct atmospheric) were measured for 13 years during which, large reductions in P and then lesser reductions in N-loading occurred ...

The continental shelf adjacent to the Mississippi River is a highly productive system, often referred to as the fertile fisheries crescent. This productivity is attributed to the effects of the river, especially nutrient delivery. In the later decades of the 20th century, though, changes in the system were becoming evident ...

Long?SAGE (serial analysis of gene expression) was used to profile the transcriptome of the brown tide?forming alga, Aureococcus anophagefferens, under nutrient replete (control), and nitrogen (N) and phosphorus (P) deficiency to understand how this organism responds at the transcriptional level to varying nutrient conditions. This approach has aided A. anophagefferens ...

This data set contains the results from monitoring in the St. Thomas East End Reserves (STEER) in St. Thomas, USVI, from January 2012 to November 2013. The monitoring was conducted by project partners at the University of the Virgin Islands, and was part of a larger project to conduct an ...

NOAA’s Deep-Sea Coral Research and Technology Program (DSC-RTP) compiles a national database of the known locations of deep-sea corals and sponges in U.S. territorial waters and beyond. The database will be comprehensive, standardized, quality controlled, and networked to outside resources. The database schema accommodates both linear (trawls, transects) and point ...

While there is growing interest in understanding how marine life will respond to future ocean acidification, many coastal ecosystems currently experience intense acidification in response to upwelling, eutrophication, or riverine discharge. Such acidification can be inhibitory to calcifying animals, but less is known regarding how non-calcifying macroalgae may respond to ...

New England coastal and adjacent Nova Scotia shelf waters have a reduced buffering capacity because of significant freshwater input, making the region’s waters potentially more vulnerable to coastal acidification. Nutrient loading and heavy precipitation events further acidify the region’s poorly buffered coastal waters. Despite the apparent vulnerability of these waters, and fisheries’ ...

Ecosystem-based management (EBM) of the ocean considers all impacts on and uses of marine and coastal systems. In recent years, there has been a heightened interest in EBM tools that allow testing of alternative management options and help identify tradeoffs among human uses. End-to-end ecosystem modeling frameworks that consider a ...

Global ocean temperatures are rising, yet the impacts of such changes on harmful algal blooms (HABs) are not fully understood. Here we used high-resolution sea-surface temperature records (1982 to 2016) and temperature-dependent growth rates of two algae that produce potent biotoxins, Alexandrium fundyense and Dinophysis acuminata, to evaluate recent changes ...

Experimental assessments of species vulnerabilities to ocean acidification are rapidly increasing in number, yet the potential for short- and long-term adaptation to high CO2 by contemporary marine organisms remains poorly understood. We used a novel experimental approach that combined bi-weekly sampling of a wild, spawning fish population (Atlantic silverside Menidia ...

Purports to develop a multiscale model to measure "the refuge effect" of a marine reserve by analyzing conditions in a relatively pristine marine reserve to compare with less pristine nearby marine park environments. Uses the Tortugas Ecological Reserve within Dry Tortugas National Park (Fla.) as a case study to demonstrate ...

Increased natural and anthropogenic stresses have threatened the Earth’s ability to meet growing human demands of food, energy and water (FEW) in a sustainable way. Although much progress has been made in the provision of individual component of FEW, it remains unknown whether there is an optimized strategy to balance ...

The Cocos Island, Guam PEDs (polyethylene device) passive water sampler data set contains results of the analysis from Project 31181 funded by NOAA’s Coral Reef Conservation Program. The project involved NOAA National Center for Coastal Ocean Science, Guam Environmental Protection Agency and the United States Environmental Protection Agency. The data ...

This document describes the analytical methods used to quantify core organic chemicals in tissue and sediment collected as part of NOAA's National Status and Trends Program (NS&T) for the years 2000-2006. Organic contaminate analytical methods used during the early years of the program are described in NOAA Technical Memoranda NOS ...

We report the zygotic encystment of geographically dispersed isolates in the dinoflagellate species complex Alexandrium tamarense, in particular, successful mating of toxic Group I and nontoxic Group III isolates. However, hypnozygotes produced in Group I/III co-cultures complete no more than three divisions after germinating. Previous reports have suggested a mate ...

Dissolved oxygen is a keystone molecule that is involved in the production, consumption, and cycling of organic matter and inorganic elements in the aquatic environment. The majority of multicellular plants and animals in coastal aquatic ecosystems require oxygen for proper physiological functioning, and the biogeochemical cycling of many important inorganic ...

An ensemble smoother is used to estimate the initial conditions and mortality rates for a spatially explicit model of Alexandrium fundyense. The data assimilation procedure is effective at reducing model-data misfit in this strong constraint problem formulation. The skill of this estimation procedure is assessed through cross-validation. The estimation is ...
