Nest data for white-faced Ibis in Bear River Migratory Bird Refuge, Great Salt Lake, Utah in summer 2012 Nest data for white-faced Ibis in Bear River Migratory Bird Refuge, Great Salt Lake, Utah in summer 2012
Nest monitoring data of white-faced ibis. Data were collected at seven day intervals and provide information on success and failure of the nest during that interval. Summary vegetation and habitat data were also collected at the nest. These data support the following publication: Mark P. Herzog, Ackerman, Joshua T., Hartman, C. Alex, and Browers, Howard, 2020, Nesting ecology of White...
Geomorphic and larval lamprey surveys in tributaries of the Umpqua River, Oregon Geomorphic and larval lamprey surveys in tributaries of the Umpqua River, Oregon
Interactions between geomorphic processes at multiple scales shape the distributions of habitats, species, and life stages that a river can support. Understanding these hierarchical processes may be helpful for proactive monitoring and restoration of native Western Brook Lamprey (Lampetra richardsoni) and Pacific Lamprey (Entosphenus tridentatus) in Pacific Northwest rivers. The...
Brown Treesnake counts during visual encounter surveys at three walking paces, Guam 2016 Brown Treesnake counts during visual encounter surveys at three walking paces, Guam 2016
We evaluated three walking paces to estimate (1) how snake detection rate per unit distance changes with increasing pace, and (2) how total number of snakes found by the end of a night of surveying varies with pace when the amount of surveying time per night is held constant. For a ?fast? pace we searched the 220 meter-long transect in 10 minutes, corresponding to a walking pace of 1.32...
Continuous Monitoring Data From Great Barnstable Marsh on Cape Cod, Massachusetts, 2017-19 Continuous Monitoring Data From Great Barnstable Marsh on Cape Cod, Massachusetts, 2017-19
Salt marshes are environmental ecosystems that contribute to coastal landscape resiliency to storms and rising sea level. Ninety percent of mid-Atlantic and New England salt marshes have been impacted by parallel grid ditching that began in the 1920s–40s to control mosquito populations and to provide employment opportunities during the Great Depression (James-Pirri and others, 2009...
Effects of Late Holocene Climate and Coastal Change in Mobile Bay, Alabama: ADCIRC Model Input and Results Effects of Late Holocene Climate and Coastal Change in Mobile Bay, Alabama: ADCIRC Model Input and Results
Using the numerical model ADCIRC, astronomic tides were simulated at Mobile Bay, Alabama under scenarios of Holocene geomorphic configurations representing the period of 3500 to 2300 years before present including a breach in the Morgan Peninsula and a land bridge at Pass aux Herons (see Figure 1), as described in Smith and others, 2020. Model inputs in the form of topography and...
Detections and concentrations of compounds of emerging concern at water treatment plants and in the Trinity River Basin, Dallas, Texas, 2009-13 Detections and concentrations of compounds of emerging concern at water treatment plants and in the Trinity River Basin, Dallas, Texas, 2009-13
This data release documents water-quality data obtained as part of an assessment of compounds of emerging concern (CECs) measured in samples collected at potable water and wastewater treatment plants in Dallas and downstream from Dallas in the Trinity River from August 2009 to December 2013 by the U.S. Geological Survey in cooperation with the City of Dallas, Dallas Water Utilities...
