Shorelines from High-resolution WorldView Satellite Imagery, Real-time Kinematic Global Positioning Data, and Aerial Imagery for 2013 to 2020 for Study Sites Within Grand Bay National Estuarine Research Reserve, Mississippi Shorelines from High-resolution WorldView Satellite Imagery, Real-time Kinematic Global Positioning Data, and Aerial Imagery for 2013 to 2020 for Study Sites Within Grand Bay National Estuarine Research Reserve, Mississippi
Shoreline change analysis is an important environmental monitoring tool for evaluating coastal exposure to erosion hazards, particularly for vulnerable habitats such as coastal wetlands where habitat loss is problematic world-wide. The increasing availability of high-resolution satellite imagery and emerging developments in analysis techniques support the implementation of these data...
MODFLOW-NWT and MODPATH6 model use to analyze remedial scenarios affecting plume movement through a sole-source aquifer system, southeastern Nassau County, New York MODFLOW-NWT and MODPATH6 model use to analyze remedial scenarios affecting plume movement through a sole-source aquifer system, southeastern Nassau County, New York
A three-dimensional steady-state groundwater flow model is coupled with the particle-tracking program, MODPATH, to assess the fate and transport of volatile organic compound plumes within the Magothy and upper glacial aquifers in southeastern Nassau County, NY. Knowledge of groundwater-flow patterns and rates is essential for effective management of groundwater resources and for...
MODFLOW-NWT and MODPATH6 Used to Delineate Areas Contributing Groundwater and Travel Times to Receiving Waters in Kings, Queens, Nassau, and Suffolk Counties, New York MODFLOW-NWT and MODPATH6 Used to Delineate Areas Contributing Groundwater and Travel Times to Receiving Waters in Kings, Queens, Nassau, and Suffolk Counties, New York
A previously developed three-dimensional steady-state groundwater flow model (https://doi.org/10.3133/sir20205091) is used to assist resource managers and planners in developing informed strategies to address nitrogen loading to coastal water bodies of Long Island, New York. Coastal water bodies of Long Island are important economic and recreational resources for the region. Therefore...
MODFLOW-NWT model used to simulate water-table and freshwater/saltwater interface response to climate-change-driven sea-level rise and changes in recharge at Fire Island National Seashore, New York MODFLOW-NWT model used to simulate water-table and freshwater/saltwater interface response to climate-change-driven sea-level rise and changes in recharge at Fire Island National Seashore, New York
The U.S. Geological Survey, in cooperation with the National Park Service (NPS), developed a three-dimensional groundwater-flow model to simulate climate change related changes in depth to the water table and depth to freshwater/saltwater interfaces for the Fire Island National Seashore, New York. An existing SEAWAT three-dimensional variable-density groundwater flow and transport model...
Horizontal-to-Vertical Spectral Ratio and Depth-to-Bedrock Data for Saline-Groundwater Investigation in the Genesee Valley, New York, October-November 2016 and 2017 Horizontal-to-Vertical Spectral Ratio and Depth-to-Bedrock Data for Saline-Groundwater Investigation in the Genesee Valley, New York, October-November 2016 and 2017
In October and November of 2016 and 2017, the U.S. Geological Survey collected horizontal-to-vertical spectral ratio (HVSR) data at 104 sites in the Genesee Valley, Livingston County, New York as part of a saline-groundwater investigation in cooperation with the New York State Department of Environmental Resources. The HVSR technique, commonly referred to as the passive-seismic method...
Protein and Fat Consumption of Zoo Polar Bears in 14-day Ad Libitum Trials, 2019-2020 Protein and Fat Consumption of Zoo Polar Bears in 14-day Ad Libitum Trials, 2019-2020
This is a single table containing measures of the amount of fat and meat consumed by 4 adult female and 5 adult male polar bears in U.S. zoos when provided both food sources ad libitum for 12-14 days. Trial length was intended to be 14 days, but trial dietary items ran out for two bears prior to the end of the trial (i.e., at 12 and 13 days instead of 14 days). The data set includes the...
