Two distinct microtidal estuarine systems were assessed to advance the understanding of the coastal dynamics of sea level rise in salt marshes. A coupled hydrodynamic-marsh model (Hydro-MEM) was applied to both a marine-dominated (Grand Bay, Mississippi) and a mixed fluvial/marine (Weeks Bay, Alabama) system to compute marsh productivity, marsh migration, ...

This work outlines a dynamic modeling framework to examine the effects of global climate change, and sea level rise (SLR) in particular, on tropical cyclone-driven storm surge inundation. The methodology, applied across the northern Gulf of Mexico, adapts a present day large-domain, high resolution, tide, wind-wave, and hurricane storm surge ...

Water masses can become undersaturated with oxygen when natural processes alone or in combination with anthropogenic processes produce enough organic carbon that is aerobically decomposed faster than the rate of oxygen re-aeration. The dominant natural processes usually involved are photosynthetic carbon production and microbial respiration. The re-supply rate is indirectly ...

Observations and numerical modeling indicate that a mesoscale anti-cyclonic eddy formed south of Cape Ann at the northern entrance of Massachusetts Bay (MB) during May 2005, when large river discharges in the western Gulf of Maine and two strong Nor'easters passing through the regions led to an unprecedented toxic Alexandrium ...

The EcoGIS project was launched in September 2004 to investigate how Geographic Information Systems (GIS), marine data, and custom analysis tools can better enable fisheries scientists and managers to adopt Ecosystem Approaches to Fisheries Management (EAFM). EcoGIS is a collaborative effort between NOAA's National Ocean Service (NOS) and National Marine ...

Scientists from the NOAA National Centers for Coastal Ocean Science (NCCOS) documented sediment and soil characteristics, erosion rates and biological communities within the sediment placement region and in undisturbed inter‐and subtidal regions of Mordecai Island from 2017 – 2019. The goal of these efforts was to quantify the immediate success ...

This report is an assessment of key physical, chemical, and biological attributes that influence the natural and cultural resources of western mid-lake Lake Michigan. It is a synthesis of existing scientific literature and a collection of new ecological data that substantially expands the body of ecological knowledge within Lake Michigan ...

This document provides an assessment of ecological condition in coastal ocean and estuarine waters of the U.S. South Atlantic Bight from Cape Henry, Virginia, through the southern end of the Indian River Lagoon along the east coast of Florida. Data are from sampling conducted in open shelf waters during March-April ...

This document provides an assessment of ecological condition, with an emphasis on soft-bottom habitats and overlying waters, along the U.S. continental shelf in the northeastern Gulf of Mexico, from Anclote Key on the west coast of Florida to the Mississippi River Delta. Sampling was conducted in August 2010, approximately one ...

This document presents the results of an assessment of ecological condition and potential stressor impacts in coastal-ocean waters of the mid-Atlantic Bight (MAB), along the eastern U.S. continental shelf from Cape Cod, MA to Cape Hatteras, NC, based on sampling conducted in May 2006. The project was a collaborative effort ...

This document provides an assessment of the status of ecological condition in coastal-ocean waters along the U.S. continental shelf, from the Strait of Juan de Fuca, WA to the Mexican border, based on sampling conducted in June 2003. The project was a large collaborative effort by the U.S. Environmental Protection ...

This document provides an assessment of ecological condition, with an emphasis on soft-bottom habitats, in coastal ocean waters of the U.S. continental shelf off south Florida, from Anclote Key on the Gulf coast to West Palm Beach on the Atlantic coast, inclusive of the Florida Keys National Marine Sanctuary. Sampling ...

The overall purpose of the study was to assess the current status of ecological condition and stressor impacts throughout these waters and to provide this information as a framework for evaluating future changes due to natural or human-induced disturbances. To address this objective, the study incorporated standard methods and indicators ...

This document presents the results of an assessment of ecological condition and potential stressor impacts in coastal-ocean waters of the Stellwagen Bank National Marine Sanctuary (SBNMS), based on sampling conducted in June 2008. The project was a collaborative effort by the U.S. Environmental Protection Agency (EPA) and the National Oceanic ...

Policy makers, natural resource managers, regulators, and the public often call on scientists to estimate the potential ecological changes caused by both natural and human-induced stresses, and to determine how those changes will impact people and the environment. To develop accurate forecasts of ecological changes we need to: 1) increase ...

The major focus of this handbook is on introducing and illustrating concepts of environmental valuation, among them Travel Cost models and Contingent Valuation. These concepts, combined with advances in natural sciences that allow us to better understand how changes in the natural environment influence human behavior, aim to address some ...

This study focuses on the ecosystem of coastal habitats (e.g., seagrass beds, marshes, and coastal forests), which operate as natural infrastructure, and can benefit coastal communities, other types of human development, and economic activity by reducing the impacts of coastal hazards. This study used the “damages avoided” method, in which ...

Mesophotic reef corals remain largely unexplored in terms of the genetic adaptations and physiological mechanisms to acquire, allocate, and use energy for survival and reproduction. In the Hawaiian Archipelago, the Leptoseris species complex form the most spatially extensive mesophotic coral ecosystem known and provide habitat for a unique community. To ...

Brown tides of the pelagophytes Aureococcus anophagefferens Hargraves et Sieburth and Aureoumbra lagunensis DeYoe et Stockwell have formed ecosystem disruptive algal blooms in shallow estuaries of the United States and South Africa for more than two decades. These algae achieve maximum growth rates at low light and nutrient levels and ...
