Low dissolved oxygen (DO) and hypoxia (DO&lt;2 mg l-1) in estuarine ecosystems presents unique challenges to marine species which are worsened by coincident low pH or acidification resulting from eutrophication. Few studies have documented spatiotemporal gradients of hypoxia and ...

High-level overview of the types of nature-based strategies suggested for Crisfield based on matching known success criteria for storm surge and erosion prevention from the literature with conditions in different parts of Crisfield's offshore ecosystems and marshlands. Includes g...

The dynamics of any given environmental decision-making context are complicated, including how to consider social-ecological systems connections. Decision support tools designed with a user in mind make it simpler and more natural to integrate science into the decision-making pro...

Air quality regulations decreased nitrogen (N) and sulfur deposition across the conterminous United States (CONUS) during the last several decades. But it is unclear if declining deposition has also altered stream N at large scales. We compared watershed N inputs with N chemistry...

Globally, wildfires are increasing in extent, frequency, and severity. Although global climate change is a major driver and large-scale governance interventions are essential, focusing on governance at smaller scales is of great importance for fostering resilience to wildfires. I...

If a water body in the United States is not as healthy as we&rsquo;ve decided it should be, the most likely cause is nutrient pollution &lt;span style='mso-element:field-begin'&gt;&lt;span style='mso-spacerun:yes'&gt;&nbsp;ADDIN EN.CITE &lt;EndNote&gt;&lt;Cite&gt;&lt;Author&gt;US...

EPA&rsquo;s Report on the Environment (ROE) brings together the most reliable and readily available indicators to create a comprehensive view of the nation&rsquo;s environmental and human health status and trends. The indicators provide an objective basis for Agency decision maki...

Wildfire risk to aquatic ecosystems in the Pacific Northwest is a growing concern, but this risk is not equally distributed across the region. Furthermore, risks vary among valued endpoints and may be perceived differently by drinking water providers, forest managers, and fish bi...

The emergence and development of next-generation sequencing technologies (NGS) has made the analysis of the water microbiome in the drinking water distribution systems (DWDSs) more accessible and opens new perspectives in microbial ecology studies. The current study focused on th...

Anthropogenic pollution of hydrological systems affects diverse communities and ecosystems around the world. Data analytics and modeling tools play a key role in fighting this challenge, as they can help identify key sources as well as trace transport and quantify impact within c...

The U.S. Environmental Protection Agency (EPA) is conducting a national stated preference study that seeks to quantify the non-use (existence) portion of total economic value of water quality policies across the conterminous US (CONUS). Previous work identified the ratio of obser...

The U.S. Environmental Protection Agency (EPA) is conducting a national stated preference study that aims to quantify the total economic value (human use and existence value) of water quality policies across the conterminous US (CONUS). Previous work identified the ratio of obser...

Sediments are a major sink for microplastics (MP) and while methods for extracting and identifying MP in sediment have improved in recent years, these methods continue to be time and cost intensive and scientifically rigorous. The cost of specialized identification instrumentatio...

Tidal wetlands sequester and store large quantities of organic carbon in their sediments and plant biomass, termed blue carbon. Assessing spatial variability in blue carbon storage and determining the environmental factors that influence that variability is important for wetland ...

Climate change and human activities may alter the structure and function of boreal peatlands by warming waters and changing patterns in hydrology. Algal assemblages, especially diatoms can be used to assess or track these changes. However, effective biomonitoring requires consist...

It is imperative to develop sampling and analytical methods to characterize FTOHs in indoor air for the development of mass transfer models to quantitatively predict FTOH emissions and transport for exposure assessment and risk management. This standard describes thermal desorpti...

Changes in nitrogen (N) availably affects the ability for forest ecosystems to store carbon (C). Here we undertake an analysis of the growth and survival of 94 tree species and 1.2 million trees, to estimate the incremental effects of N deposition on changes in above ground carbo...

Along the trajectory of restoration implementation from planning to post-restoration monitoring, resource managers have identified a need for information and approaches to help inspire the public to act, evaluate alternatives, gain public support, monitor progress, and communicat...

Riparian Proper Functioning Condition (PFC) refers to a qualitative description of the potential state of a riparian ecosystem: proper functioning condition, functional-at-risk, apparent trend, or non-functional. These states are influenced by the dynamic nature of the hydrologic...

This sub-product is intended to synthesize existing research and datasets for assessing the blue carbon characteristics of natural infrastructure currently in Chesapeake Bay, with a focus on the blue carbon habitats and natural infrastructure relevant for the Crisfield, MD commun...

Quantifying atmospheric loadings of total phosphorus (TP) to freshwater environments is essential to improve understanding of its fate and transport, and to mitigate the effects of excessive levels in freshwater ecosystems. To date, atmospheric deposition of TP in the U.S. is poo...

Per- and polyfluoroalkyl substances (PFAS) are widely used in commercial products such textiles, firefighting foams, and surface coatings across the globe and some PFAS are known to be bioaccumulative in aquatic species. The ultimate sink for numerous anthropogenic chemicals is t...

Birds frequently serve as faunal indicators of remediation and restoration effectiveness. In riparian settings, birds are trophically linked to water via consumption of aquatic prey and thereby integrate riparian and aquatic ecosystems. There are 14 Beneficial Use Impairments (BU...

Eutrophication and nutrient related water quality issues are an increasing threat to coastal, estuarine, and freshwater ecosystems across the globe. Managers and policy makers commonly rely on complex simulation models to address water quality impacts and to predict outcomes from...
