Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

ModelMuse Version 5.0: Software Release ModelMuse Version 5.0: Software Release
ModelMuse is a graphical user interface for several different groundwater modeling programs. ModelMuse has been updated to generate the input files for the parameter estimation software suite PEST when used with MODFLOW or SUTRA models, run PEST-based parameter estimation, and display the updated model inputs after parameter estimation. The PEST input files can also be used with PEST++...
Point Sampling Data for Eelgrass (Zostera marina) and Widgeongrass (Ruppia marina) Abundance in Embayments of the North Pacific Coast of Baja California, Mexico Point Sampling Data for Eelgrass (Zostera marina) and Widgeongrass (Ruppia marina) Abundance in Embayments of the North Pacific Coast of Baja California, Mexico
These data are in seven tables relating to surveys of eelgrass (Zostera marina) and widgeongrass (Ruppia maritima) beds in embayments of the north Pacific coast of Baja California, Mexico. The tables provide environmental conditions, eelgrass and widgeongrass abundance, and measurements used to estimate their aboveground biomass. These tables also provide information on percent cover...
Point Sampling for Eelgrass (Zostera marina) and Seaweeds in Duchikthluk and Shoal Bays of Nunivak Island, Alaska, 2010 Point Sampling for Eelgrass (Zostera marina) and Seaweeds in Duchikthluk and Shoal Bays of Nunivak Island, Alaska, 2010
These data are in seven tables relating to surveys of eelgrass beds in Duchikthluk and Shoal Bays of Nunivak Island, Alaska. The tables provide environmental conditions, eelgrass abundance, distribution, and measurements used to estimate overall biomass. These tables also provide information on percent cover and location of eelgrass and seaweeds/bluegreen algae, biomass of eelgrass...
Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, July 2018 Bathymetry, topography, and sediment grain-size data from the Elwha River delta, Washington, July 2018
Two dams on the Elwha River, Washington State, USA trapped over 20 million m3 of sediment, reducing downstream sediment fluxes and contributing to erosion of the river's coastal delta. The removal of the Elwha and Glines Canyon dams between 2011 and 2014 induced massive increases in river sediment supply and provided an unprecedented opportunity to examine the response of a delta system...
Topobathymetric Model of the Coastal Carolinas, 1851 to 2020 Topobathymetric Model of the Coastal Carolinas, 1851 to 2020
To support Hurricane Florence impact modeling of storm-induced flooding and sediment transport, the U.S. Geological Survey (USGS) Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for coastal North Carolina, and South Carolina. High-resolution coastal topobathymetric data are required to...
Pesticide Concentrations Measured in Zooplankton Samples Collected from the Sacramento River and Yolo Bypass, California, 2017-2020 Pesticide Concentrations Measured in Zooplankton Samples Collected from the Sacramento River and Yolo Bypass, California, 2017-2020
Zooplankton samples were collected at a site in the Yolo Bypass in Northern California and at a comparison site on the Sacramento River below the city of Sacramento and analyzed for a large suite of current-use pesticides and degradates. Samples were collected biweekly in the summer/fall 2017 and 2018, and from May 2019-March 2020. Samples were collected by towing a 150-micron conical...
