Coastal wetlands store carbon dioxide (CO2) and emit CO2 and methane (CH4) making them an important part of greenhouse gas (GHG) inventorying. In the contiguous United States (CONUS), a coastal wetland inventory was recently calculated by combining maps of wetland type and change with soil, biomass, and CH4 flux data from a...

Ning Wang, James L. Kunz, Rebecca A. Dorman, Christopher G. Ingersoll, Jeffery A. Steevens, Edward J. Hammer, Candice R. Bauer
2018, Environmental Toxicology and Chemistry (37) 3050-3062
Freshwater mussels are generally underrepresented in toxicity databases used to derive water quality criteria, especially for long‐term exposures. Multiple tests were conducted to determine the chronic toxicity of sodium chloride (NaCl) or potassium chloride (KCl) to a unionid mussel (fatmucket, Lampsilis siliquoidea). Initially, a 4‐wk NaCl test...

Assessing cropland area in west Africa for agricultural yield analysis
K. Samasse, N.P. Hanan, G. Gray Tappan, Y. Diallo
2018, Remote Sensing (10)
Accurate estimates of cultivated area and crop yield are critical to our understanding of agricultural production and food security, particularly for semi-arid regions like the Sahel of West Africa, where crop production is mainly rain-fed and food security is closely correlated with the inter-annual variations in rainfall. Several global...

Ronni Grapenthin, Sigrun Hreinsdottir, Alexa R. Van Eaton
2018, Geophysical Research Letters (45) 12,236-12,243
Volcanic plumes are challenging to detect and characterize rapidly, but insights into processes such as hail formation or ash aggregation are valuable to hazard forecasts during volcanic crises. Global Navigation Satellite System (GNSS, which includes GPS) signals traveling from satellites to ground receivers can be disturbed by...

Bias correction of simulated historical daily streamflow at ungauged locations by using independently estimated flow duration curves
William H. Farmer, Thomas M. Over, Julie E. Kiang
2018, Hydrology and Earth System Sciences (22) 5741-5758
In many simulations of historical daily streamflow distributional bias arising from the distributional properties of residuals has been noted. This bias often presents itself as an underestimation of high streamflow and an overestimation of low streamflow. Here, 1168 streamgages across the conterminous USA, having at least 14 complete water years of daily data...

2018, Techniques and Methods 7-A2
IntroductionGenEst (a generalized estimator of mortality) is a suite of statistical models and software tools for generalized mortality estimation. It was specifically designed for estimating the number of bird and bat fatalities at solar and wind power facilities, but both the software (Dalthorp and others, 2018) and the underlying...
Contribution of hurricane-induced sediment resuspension to coastal oxygen dynamics
Laura Bianucci, Karthik Balaguru, Richard W. Smith, Ruby Leung, Julia M. Moriarty
2018, Scientific Reports (8) 1-10
Hurricanes passing over the ocean can mix the water column down to great depths and resuspend massive volumes of sediments on the continental shelves. Consequently, organic carbon and reduced inorganic compounds associated with these sediments can be resuspended from anaerobic portions of the seabed and re-exposed to dissolved oxygen...

2018, PLoS ONE (13) 1-14
Multi-state occupancy modeling can often improve assessments of habitat use and site quality when animal activity or behavior data are available. We examine the use of the approach for evaluating foraging habitat suitability of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus) from classifications of site occupancy based on flight...
Using research networks to create the comprehensive datasets needed to assess nutrient availability as a key determinant of terrestrial carbon cycling
Sara Vicca, Benjamin Stocker, Sasha C. Reed, William R. Wieder, Michael Bahn, Philip A. Fay, Ivan Janssens, Hans Lambers, Josep Penuelas, Shilong Piao, Karin Rebel, Jordi Sardans, Bjarni D. Sigurdsson, Kevin Van Sundert, Ying-Ping Wang, Sonke Zaehle, Philippe Ciais
2018, Environmental Research Letters (13) 1-13
A wide range of research shows that nutrient availability strongly influences terrestrial carbon (C) cycling and shapes ecosystem responses to environmental changes and hence terrestrial feedbacks to climate. Nonetheless, our understanding of nutrient controls remains far from complete and poorly quantified, at least partly due to a lack of informative,...

Land subsidence
Michelle Sneed
2018, Book chapter, Groundwater: State of the science and practice
Land subsidence in the United States is inextricably linked to the development of groundwater—one of the Nation’s most valuable natural resources. More than 80 percent of the identified subsidence in the United States is a consequence of anthropogenic impact on water resources. Three processes account for most of the water-related...

1. The total flux of carbon—which includes gaseous emissions, lateral flux, and burial—from inland waters across the conterminous United States (CONUS) and Alaska is 193 teragrams of carbon (Tg C) per year. The dominant pathway for carbon movement out of inland waters is the emission of carbon dioxide gas across...

Katherine Van Sice, Charles A. Cravotta III, Bonnie McDevitt, Travis L. Tasker, Joshua D. Landis, Johnna Puhr, Nathaniel R. Warner
2018, Applied Geochemistry (98) 393-403
Centralized waste treatment facilities (CWTs) in Pennsylvania discharged wastewater from conventional and unconventional oil and gas (O&G) wells into surface waters until 2011, when a voluntary request from the Pennsylvania Department of Environmental Protection (PA DEP) encouraged recycling rather than treating and discharging unconventional O&G wastewater. To determine the effect of this request on the occurrence of radium in...

Automated road breaching to enhance extraction of natural drainage networks from elevation models through deep learning
Larry Stanislawski, Tyler Brockmeyer, Ethan J. Shavers
2018, Conference Paper, The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
High-resolution (HR) digital elevation models (DEMs), such as those at resolutions of 1 and 3 meters, have increasingly become more widely available, along with lidar point cloud data. In a natural environment, a detailed surface water drainage network can be extracted from a HR DEM using flow-direction and flow-accumulation modeling....
