A NOAA partnership with the Federal Highway Administration (FHWA) received a U.S. Department of Transportation FHWA Environmental Excellence Award, which recognizes outstanding transportation projects, processes, and organizations that incorporate environmental ...

Oregon Researchers Engage Decision-makers to Suppo...

Last month, Oregon State University hosted a hybrid Oregon Dune Management Conference and Workshop online and at the Hatfield Marine Science Center in Newport, Oregon. The workshop provided an update ...

Harmful Algal Blooms May Soon Wreak Havoc in Arcti...

Climatic changes in Arctic Alaska are resulting in more harmful algal blooms (HABs) for the region, signaling a potential growing threat to human and ecosystem health. Over the last decade, ...

Researchers Determine Flood Risk for 13 Coastal Co...

Coastal communities need to know what actions to take to mitigate flooding, now and in the future as sea level rises. A new NCCOS-funded study helps meet this need by ...

NCCOS Publishes Social Vulnerability Assessment in...

Coastal communities are increasingly vulnerable to climate-driven impacts, such as sea level rise and coastal erosion. To address these risks in the Puget Sound region of Washington, Washington Sea Grant ...

Developing and managing transdisciplinary and transformative research on the coastal dynamics of sea level rise: Experiences and lessons learned

There is increasing emphasis from funding agencies on transdisciplinary approaches to integrate science and end-users. However, transdisciplinary research can be laborious and costly and knowledge of effective collaborative processes in these endeavors is incomplete. More guidance grounded in actual project ...

Diel differences in abundance and diversity of fish species and blue crab (Callinectes sapidus) in the sandy beach shore zone of lower Delaware Bay

Diel sampling was conducted during June–September 2013, in the shore zone and adjacent nearshore zone of Delaware Bay, Delaware, to identify day and night changes in nekton density, species richness, and the species assemblage. Mean species richness and total nekton ...

Direct and indirect impacts of shoreline development on shallow-water benthic communities in a depauperate estuarine system

Modification of natural coastlines is prevalent as human coastal populations swell and effects of global climate change become clearer. We investigated effects of shoreline hardening and environmental factors on benthic infauna and trophic structure in the Patuxent River, Maryland, a ...

Diurnal Fluctuations in Acidification and Hypoxia Reduce Growth and Survival of Larval and Juvenile Bay Scallops (Argopecten irradians) and Hard Clams (Mercenaria mercenaria)

Diurnal variations in pH and dissolved oxygen (DO) concentrations are common seasonal phenomena in many eutrophic estuaries, yet few studies have investigated the concurrent effects of low pH and low DO on marine organisms inhabiting these coastal systems. Here, we ...

Diurnal fluctuations in CO2 and dissolved oxygen concentrations do not provide a refuge from hypoxia and acidification for early-life-stage bivalves

This study assessed the effects of constant and diurnally fluctuating acidification and hypoxia on the survival, growth, and development of larval stages of 3 bivalves indigenous to the east coast of North America: bay scallops Argopecten irradians, hard clams Mercenaria ...

Dynamic responses and implications to coastal wetlands and the surrounding regions under sea level rise

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 ...

Dynamic simulation and numerical analysis of hurricane storm surge under sea level rise with geomorphologic changes along the northern Gulf of Mexico

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 ...

Ecosystem Metabolism

This chapter contains sections titled: Introduction; Basic Definitions and Concepts; Measuring Ecosystem Metabolism; Regulating Factors and Spatial/Temporal Patterns; Ecosystem Metabolism Case Studies; Cross?Ecosystem Comparisons; Metabolic Responses to Climate Change and Variability; Conclusions; Acknowledgments; References; Citing Literature ...

Effects of Local Shoreline and Subestuary Watershed Condition on Waterbird Community Integrity: Influences of Geospatial Scale and Season in the Chesapeake Bay

In many coastal regions throughout the world, there is increasing pressure to harden shorelines to protect human infrastructures against sea level rise, storm surge, and erosion. This study examines waterbird community integrity in relation to shoreline hardening and land use ...

Effects of Local Watershed Land Use on Water Quality in Mid-Atlantic Coastal Bays and Subestuaries of the Chesapeake Bay

Nutrient inputs have degraded estuaries worldwide. We investigated the sources and effects of nutrient inputs by comparing water quality at shallow (< 2m deep) nearshore (within 200 m) locations in a total of 49 Chesapeake subestuaries and Mid-Atlantic coastal bays ...
