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.

Reach-scale predicted annual streamflow permanence probabilities, predicted monthly mean stream temperature for August, and predicted monthly streamflow discharge for stream reaches in the Pacific Northwest, USA (2004-2015) (ver. 2.0, January 2023) Reach-scale predicted annual streamflow permanence probabilities, predicted monthly mean stream temperature for August, and predicted monthly streamflow discharge for stream reaches in the Pacific Northwest, USA (2004-2015) (ver. 2.0, January 2023)
This dataset is a combination of annual Probability of Streamflow Permanence (PROSPER) predictions, Northwest Stream Temperature (NorWeST) predictions of monthly mean stream temperatures for August of each year, and predicted monthly streamflow discharge for stream reaches in the Pacific Northwest from the USGS database of natural monthly streamflow estimates, U.S., 2004-2015. The...
Grain-Size Data from Upper Florida Keys: Crocker Reef, FL Grain-Size Data from Upper Florida Keys: Crocker Reef, FL
Sediment samples were collected from undisturbed sections of the seafloor around Crocker Reef, Florida which is a senile, degrading barrier reef located in the northern portion of the Florida Reef Tract (Figure 1). Samples were collected from November 2017 to April 2019. The sediment sample locations were near instruments deployed during the same period to record time series of ocean...
Aerial Imagery of the North Carolina Coast: 2019-11-26 Aerial Imagery of the North Carolina Coast: 2019-11-26
The U.S. Geological Survey (USGS) Remote Sensing Coastal Change (RSCC) project collects aerial imagery along coastal swaths, in response to storm events, with optimized endlap/sidelap and precise position information to create high-resolution orthomosaics, three-dimensional (3D) point clouds, and digital elevation/surface models (DEMs/DSMs) using Structure-from-Motion (SfM)...
MODFLOW-USG model used to evaluate water management issues in the Los Angeles Coastal Plain, California MODFLOW-USG model used to evaluate water management issues in the Los Angeles Coastal Plain, California
Seven model data sets are archived for this groundwater study. One simulation for the Los Angeles Coastal Plain groundwater model and six scenario simulations to evaluate the effects of future production well rate increases to reach maximum adjudicated rates and construction of new well fields. Simulations were run with MODFLOW-USG.
Spatial Database of Known and Potential Cienegas in the Greater Madrean Archipelago Ecoregion Spatial Database of Known and Potential Cienegas in the Greater Madrean Archipelago Ecoregion
This dataset provides location information and some limited attributes of known and potential cienegas in the Madrean Archipelago ecoregion and closely surrounding area. This was created using point data and information provided by Dean Hendrickson and Thomas Minckley, combined with potential locations derived from analysis of classified raster land cover images and other specialized...
Codebook vectors and predicted rare earth potential from a trained emergent self-organizing map displaying multivariate topology of geochemical and reservoir temperature data from produced and geothermal waters of the United States Codebook vectors and predicted rare earth potential from a trained emergent self-organizing map displaying multivariate topology of geochemical and reservoir temperature data from produced and geothermal waters of the United States
This data release consists of three products relating to a 82 x 50 neuron Emergent Self-Organizing Map (ESOM), which describes the multivariate topology of reservoir temperature and geochemical data for 190 samples of produced and geothermal waters from across the United States. Variables included in the ESOM are coordinates derived from reservoir temperature and concentration of Sc, Nd...
