AndreaBozzo/ceres-open-data-index huggingface dataset:
Baselines for the coast of Nantucket, Massachusetts, generated to calculate shoreline change rates using the Digital Shoreline Analysis System version 5.1

The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast by compiling a database of historical (mid 1800's-1989) shoreline positions. Trends of shoreline position over long and short-term timescales provide information to landowners, managers, and potential buyers about possible future impacts to coastal resources and infrastructure.  In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates along ocean-facing sections of the Massachusetts coast. In 2013, two oceanfront shorelines for Massachusetts were added using 2008-2009 color aerial orthoimagery and 2007 topographic lidar datasets obtained from the National Oceanic and Atmospheric Administration's Ocean Service (NOAA), Coastal Services Center. In 2018, two new mean high water (MHW) shorelines for the Massachusetts coast extracted from lidar data between 2010-2014 were added to the dataset. This 2021 data release includes rates that incorporate one new shoreline from lidar data extracted in 2018 by the U.S. Army Corps of Engineers (USACE) Joint Airborne Lidar Bathymetry Technical Center of Expertise (JALBTCX), added to the existing database of all historical shorelines (1844-2014), for the North Shore, South Shore, Cape Cod Bay, Outer Cape, Buzzard’s Bay, South Cape, Nantucket, and Martha’s Vineyard. 2018 lidar data did not cover the Boston or Elizabeth Islands regions. Included in this data release is a proxy-datum bias reference line that accounts for the positional difference in a proxy shoreline (the High Water Line shoreline) and a datum shoreline (the Mean High Water shoreline). This issue is explained further in Ruggiero and List (2009) and in the process steps of the metadata associated with the rates. This release includes both long-term (~150+ years) and short term (~30 years) rates.  Files associated with the long-term rates have “LT” in their names, files associated with short-term rates have "ST” in their names.

1_Alaska NHM by-HRU mean-monthly calibration targets derived from Global Circulation Model (GCM) simulations, 1980 – 2022

This data release contains inputs for and outputs from hydrologic simulations for the Alaska (AK) domain using the Precipitation Runoff Modeling System (PRMS) version 5.2.1.1 and the USGS National Hydrologic Model infrastructure (NHM, Regan and others, 2018). This child item holds NetCDF files and methodology to make mean-monthly calibration targets (baselines) for the AK domain, as was used in the “byHRU” calibration. Global Circulation Model (GCM) data from National Aeronautics and Space Administration (NASA) were processed into 10 mean-monthly global datasets (Koczot and others, 2025) and stored in NetCDF format (.nc file extension; https://www.unidata.ucar.edu/software/netcdf/). Using these datasets, mean-monthly values were computed for each hydrologic response unit (HRU) in the AK domain (Bock and others, 2024). Resulting data are used as calibration targets for the AK NHM-PRMS model application.

Lake Koocanusa Stage-Area-Capacity Tables, Lincoln County, Montana, 2016—2018

In 2016, the U.S. Army Corps of Engineers (USACE) started collecting high-resolution multibeam echosounder (MBES) data on Lake Koocanusa. The survey originated near the International Boundary (River Mile (RM) 271.0) and extended down the reservoir, hereinafter referred to as downstream, about 1.4 miles downstream of the Montana 37 Highway Bridge near Boulder Creek (about RM 253). USACE continued the survey in 2017, completing a reach that extended from about RM 253 downstream to near Tweed Creek (RM 244.5). In 2018, the U.S. Geological Survey (USGS) Idaho Water Science Center completed the remaining portion of the reservoir from RM 244.5 downstream to Libby Dam (RM 219.9). The MBES data collected in 2016 and 2017 by the USACE was combined with the MBES data collected in 2018 by the USGS. The USGS also developed a stage-area-capacity table at one-foot intervals from the minimum pool elevation (2,290.84 ft) to the maximum pool elevation (2462.84 ft) using the new bathymetry data. The updated stage-area-capacity table will be compared to the current usable storage estimate of 4,979,500 acre-feet and published in a USGS Scientific Investigations Map. A 10-ft digital elevation model (DEM) and minimum and maximum pool contours also were generated from the bathymetric data and are provided in this data release.

Magnetotelluric and TEM Data from the Umatilla Indian Reservation Geothermal Resources  Assessment: Phase 2, 2020: Station um211

This data set consists of 19 wideband magnetotelluric (MT) and 23 transient electromagnetic (TEM) soundings collected by the U.S. Geological Survey in June 2020 as part of the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2 project. Each MT station had 4 components, 2 orthogonal magnetic induction coils and 2 horizontal orthogonal electric dipoles.  Data were collected for an average of 18 hours on a repeating schedule of alternating sampling rates of 256 samples/second for 5 hours and 50 minutes and 4096 samples/second for 10 minutes.  The schedules were set such that each station was recording the same schedule to allow for remote reference processing.  Data were processed with a bounded-influence robust remote reference processing scheme (BIRRP v5.2.1, Chave and Thomson, 2004).  Data quality were generally poor due to episodic spikes in the electromagnetic fields likely caused by the power grid.  TEM data were collected in 100 x 100 m loops or 40 x 40 m loops along 4 profiles in areas of interest for geothermal potential.  Files included in this publication include measured electric- and magnetic-field time series for MT data, and TEM soundings and 1-D resistivity models.

Grasshopper Sparrow (Ammodramus savannarum ammolegus) calculated territory size Arizona 2009-2013

Ammodramus savannarum ammolegus (commonly referred to as the Arizona Grasshopper Sparrow) occurs in the desert and plains grasslands of southeastern Arizona, southwestern New Mexico, and northern Sonora, Mexico.  Although a subspecies of conservation concern, this data was produced as part of the first intensive study of its life history and breeding ecology, providing baseline data and facilitating comparisons with other North American Grasshopper Sparrow subspecies.  This study is described in the publication listed in the larger work citation of this metadata record.
In 2011 through 2013,  I mapped territories of male Grasshopper Sparrows and calculated territory size.  A 95% kernel density estimate was used to calculate territory size.

Rangeland Condition Monitoring Assessment and Projection (RCMAP) Sagebrush Fractional Component Time-Series Across Western North America from 1985-2023

The RCMAP (Rangeland Condition Monitoring Assessment and Projection) dataset quantifies the percent cover of rangeland components across western North America using Landsat imagery from 1985-2023. The RCMAP product suite consists of ten fractional components: annual herbaceous, bare ground, herbaceous, litter, non-sagebrush shrub, perennial herbaceous, sagebrush, shrub, tree, and shrub height in addition to the temporal trends of each component. Several enhancements were made to the RCMAP process relative to prior generations. First, high-resolution training was revised using an improved neural-net classifier and modelling approach. These data serve as foundation to the RCMAP approach. The training database was further improved by incorporating additional datasets. Next, the Landsat compositing approach was improved to better capture the range of conditions from across each year and through time. These composites are based on Collection 2 Landsat data with improved geolocation accuracy and dynamic range. Finally, the Canadian portion of the sagebrush biome was included, which expanded the study area by 29,199 km2. 
Processing efficiency has been increased using open-source software and USGS High-Performance Computing (HPC) resources. The mapping area included eight regions which were subsequently mosaicked. These data can be used to answer critical questions regarding the influence of climate change and the suitability of management practices. Component products can be downloaded https://www.mrlc.gov/data.

HW1_Q25.TIF - Hawaii I - Southeastern Hawaiian Ridge U.S. EEZ GLORIA sidescan-sonar data mosaic (25 of 29) (LCC, 50 m, WGS84)

Survey of the southeastern Hawaiian Ridge was the fifth major segment of the Exclusive Economic Zone (EEZ) mapping program to have been initiated. Data acquisition for this region required approximately one-half year and were acquired during eight cruises over a four year period from 1986 through 1989, skipping 1987. At the conclusion of the survey 29 mosaics of a 2 degree by 2 degree were completed for the region. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of twenty-seven digital mosaics of a 2 degree by 2 degree area and 2 mosaics of 2.25 degree by 2 degree with a 50-meter pixel resolution were completed for the region.

HAVO Montane Ohia Diameter and Cavity Data 2017

We quantified the availability of breeding habitat of the endangered Hawaiian Akepa (Loxops coccineus). The species is thought to nest excusively in natural cavities within mature ohia (Metrosideros polymorpha) trees but birds commonly occur in short stature trees that presumably do not have any natural cavities because of their polyploidal (many-branched) structure. To test this hypothesis we searched for cavities in trees where akepa forage and we measured diameter of each stem of each tree examined. The habitat is in montane areas of Hawaii Volcanoes National Park on Mauna Loa volcano.We surveyed 57 plots, 49 in montane woodland and 8 in closed-canopy forest. Six tree cavities were detected in the 214 sampled trees: five cavities were found in 38 trees sampled in closed canopy forest (8.9/ha) and only one cavity was found in 176 trees sampled in montane woodland (0.29/ha). Tree diameters in the forest ranged from 10 cm to 128 cm diameter at breast height (DBH), while those in the woodland were much smaller ranging from 10 cm to a maximum DBH of 54 cm. Most trees in the closed-canopy forest were monopodial (87%, mean number of stems per tree = 1.16, SE = 0.07) with only five of the 38 trees having multiple stems at DBH height. In contrast, most trees in the woodland were sympodial (61%, mean number of stems per tree = 2.11, SE = 0.11) where 108 of the 176 trees had multiple stems. This data release includes two CSV files: the ohia measurements and locations.

Hydrogeologic framework bottom elevations and thicknesses of Permian, Upper Pennsylvanian, Lower Pennsylvanian, and Mississippian units in the Appalachian Plateaus Physiographic Province

As part of the U.S. Geological Survey Water Availability and Use Science Program 
study of Appalachian Plateaus aquifers, bottom elevations and thicknesses were 
determined for Permian, Upper Pennsylvanian, Lower Pennsylvanian, and 
Mississippian hydrogeologic framework units in the Appalachian Plateaus, 
covering parts of Pennsylvania, Maryland, Ohio, West Virginia, Kentucky, 
Virginia, Tennessee, Georgia, and Alabama. Thickness values for these 
units were compiled at point locations from available sources (Martens, 
1945; McKee and Crosby, 1975; Craig and Connor, 1979; Ryder and others, 
2008, 2009, 2012, 2015) and used to interpolate surfaces representing 
thicknesses, contact elevations, and outcrop elevations using earthVision 
software (Dynamic Graphics, Inc., 2014). Unit contact and outcrop elevations 
at cell centers from the earthVision rasters were used as the primary source 
to create geodatabase rasters representing bottom elevations and thicknesses 
of the Permian, Upper Pennsylvanian, Lower Pennsylvanian, and Mississippian 
framework units.
