+ "description": "This data release consists of four datasets which were used for evaluating winter drawdown (WD) lakes to follow the Massachusetts general WD guidelines. The first dataset (\"Water level observations.csv\") provides water level monitoring data of 21 (18 WD and 3 non-WD) recreational lakes in Massachusetts from 2014 to 2018. The water levels were measured by paired nonvented pressure transducers (HOBO U20L-01) and processed by ContDataQC package to remove potential inaccurate observations. For better comparison between lakes, the water level was relativized to each lake's normal pool level. This dataset was used for understanding the hydrology of WD and non-WD lakes and validating the hydrological model that we developed for WD lakes. Details of the hydrological model were described in the software release (https://doi.org/10.5066/P9C8BVY2). The second dataset (\"Water level simulations.csv\") is the hydrological model simulated daily water level (relative to each lake's normal pool level) time series of the WD lakes from the first dataset (15 lakes, 2014-2018). To validate the applicability of the model on simulating water levels in WD lakes, the actual drawdown rules were set in the model to recreate the historical water levels and compare with the in-situ observations in the first dataset. The third dataset (\"Guideline_Eval_Dec1drawdown.csv\") contains the probability of each WD lake reaching the drawdown level by Dec 1 which is required by the guidelines when selecting different drawdown magnitudes (1-6ft) by Dec 1 in 2015. 2016 and 2017. The fourth dataset (“Guidleine_Eval_Apr1refill.csv”) consists of the latest refill starting dates of each lake with different designed drawdown magnitude (1-6 ft) to ensure over 95% possibility for each WD lake to be fully refilled by Apr 1 in 2016, 2017, 2018.",

Freshwater fish and mussels survey records were used to fit species specific models that predict the probability of occurrence. The list of covariates is largely the same as the covariates released in the cross-referenced data set from Rogers et al., (2025); here, the covariate file shows the covariates used in this analysis that were not also used in the prior analysis. The species projection file has the results of the predicted probabilities of occurrence for each species of freshwater fish and mussel, at the HUC12 scale, for each of the seven scenarios: 1. baseline, 2. climate change, 3. climate change and dam removal, 4. climate change and natural riparian restoration, 5. climate change and riparian impervious removal, 6. climate change and watershed forest, and 7. climate change and a combination of numbers 3 through 6. The full methods for the fish models are described in the cited manuscript, Rogers et al., (2025); briefly, zero-inflated beta models (one for each fish species) were used to simultaneously model the probability of species occurrence and the predicted relative abundance of each fish species at the NHD Version 2 stream reach scale. The predicted probability of occurrence (from the binomial portion of the model) of each fish species at the stream reach level was averaged over the HUC12 scale to get the probability of occurrence of each of the 53 fish species by HUC12. The full methods for the mussel models are also described in Rogers et al., (In Prep); briefly we fit 12 logistic regression models (one for each mussel species) using the glm function in the stats package and the family of models set to ‘binomial’. The mussel models were fit using presence and absence data at the HUC12 scale and covariate data that was averaged across the HUC12. All models, analyses, and data visualizations were developed using R version 4.2.2 (2022-10-31 ucrt).",

  "description": "The Endangered Species Act (ESA) provides a program for the conservation of threatened and endangered species and the habitats in which they are found. The U.S. Fish and Wildlife Service (USFWS) and the National Marine Fisheries Service of U.S. National Oceanic and Atmospheric Organization (NMFS/NOAA) lead federal implementation of the ESA, though they are supported by other federal agencies, including the U.S. Environmental Protection Agency (US EPA). Section 7 of the ESA directs all Federal agencies to conserve endangered and threatened species and to use their authorities to ensure actions do not jeopardized the further existence of threatened and endangered species or adversely modify designated critical habitats. As part of the Section 7 coordination, federal agencies work with USFWS and NMFS to identify species found within the jurisdiction of the United that could be affected by actions carried out by the agency. Of note, the US EPA’s Office of Pesticide Programs (OPP) is responsible for ensuring that Agency actions under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) are in compliance with ESA. OPP determines if ESA-listed species or their designated critical habitat may be affected by pesticide products. Pesticide products that “may affect” an ESA-listed species or its designated critical habitat may be subject to additional regulation. Species ranges represent anywhere an individual of the listed species could be found based on the best available information at the time of delineation. As defined in ESA, critical habitat delineates habitat characteristics in specific geographical areas and may be occupied or unoccupied by a threatened or endangered species at the time of listing. These areas must contain physical or biological features essential to conservation of a species and may require special management considerations or protection. Critical habitat may also include areas that are not currently occupied by the species but that may be needed for their recovery. Range areas represent more generalized habitat where species are or could be found based on the best available information. For some species, best available information is based on site specific surveys. For others, it will be historical location information based on political boundaries. These areas are, therefore, less geographically explicit than critical habitat. Consideration of both the species range and critical habitat ensures the conservation of the ecosystems upon which endangered and threatened species depend. To support EPA’s implementation of ESA, critical habitat and range data for species listed under ESA Section 7 were obtained by the US EPA from the USFWS Environmental Conservation Online System (ECOS) database in November 2020. These data were supplemented with areas provided by NOAA’s National Marine Fisheries Service (NMFS) where NOAA has species authority. For NMFS species not found in either location, a request was made directly to the NMFS scientists. The last download of the species locations occurred in November 2020.",

The SPCMSC Geologic Core and Sample Database includes geologic cores and samples collected beginning in the 1970s to present day, from study sites across the world. This database captures metadata about samples throughout the USGS Science Data Lifecycle: including field collection, laboratory analysis, publication of research, and archival or deaccession. For more information about the USGS Science Data Lifecycle, see USGS Open-File Report 2013-1265 (https://doi.org/10.3133/ofr20131265). The SPCMSC Geologic Core and Sample Database also includes storage locations for physical samples and cores archived in a repository (USGS SPCMSC or elsewhere, if known). The majority of the samples and cores in this database come from field activities associated with the SPCMSC and have been assigned a field activity number (FAN) in the field activity management and data inventory tool for USGS Coastal and Marine Hazards and Resources Program (CMHRP) Coastal and Marine Geoscience Data System (CMGDS), https://cmgds.marine.usgs.gov/. Some cores and samples were retroactively assigned FANs based on existing metadata and published information. Cores and samples without FANs indicate there is insufficient information regarding collection of the core(s) or sample(s) needed in order to assign a field activity number in CMGDS. Please see the supplemental information section of the metadata for more information about FANs. All samples and cores contained in this database are described in published research. The database contains a link to the FAN page within the CMGDS for each sample or core where associated publications can be accessed.

- "description": "This dataset provides operational satellite-based drought monitoring and 7-day precipitation forecasting outputs for nine study locations across four western Pacific Island nations: the Federated States of Micronesia (FSM), the Republic of the Marshall Islands, the Republic of Nauru, and the Solomon Islands. Two complementary components are included. The first is a monthly drought monitoring record derived from NASA Integrated Multi-satellitE Retrievals for Global Precipitation Mission (IMERG) Early Run data, spanning January 2000 through February 2026. For each location and each month, the dataset reports observed monthly precipitation, the 25-year climatological median, rolling 1-, 3-, and 6-month cumulative precipitation, quintile-based Rainfall Index classifications (Drier, Dry, Typical, Wet, or Wetter), and Pacific ENSO (El Niño–Southern Oscillation) Applications Climate Center (PEAC) absolute threshold categories. The second component comprises outputs from an automated 7-day precipitation forecasting pipeline driven by NOAA Global Forecast System (GFS) GRIB2 model output at 0.25-degree spatial resolution. For each operational forecast run, the dataset includes daily precipitation forecasts (mm) for all nine study locations, site-specific bar chart graphics, georeferenced animated GIF sequences, combined multi-site visualizations, and processing logs. Forecast alert thresholds of 50 mm per day and 200 mm per 7-day period are applied to identify high-precipitation events. In addition to the data outputs, the dataset includes the complete R scripts used for data acquisition, processing, analysis, and visualization for both components, enabling reproducibility and direct reuse of the operational pipeline. Both components were developed to support evidence-based water resource management and infrastructure planning under the Asian Development Bank project \"Strengthening Resilient and Sustainable Urban and Water Service Delivery in the Pacific.\"",

- "description": "This dataset provides multi-temporal building footprint polygons across three survey epochs (early 2000s, mid-2010s, 2025) for six informal settlements across three Pacific Island nations, namely Papua New Guinea, Solomon Islands, and Fiji. It was produced under the Asian Development Bank (ADB) project “Strengthening Resilient and Sustainable Urban and Water Service Delivery in the Pacific.” The six study sites are: 8 Mile Settlement and Taurama Valley, located in Port Moresby, Papua New Guinea (survey epochs: 2010, 2016, 2025); Mbumburu and White River, located in Honiara, Solomon Islands (survey epochs: 2006, 2015, 2025); and Tacirua and Wailekutu, located in Greater Suva, Fiji (survey epochs: 2009, 2014, 2025). Source imagery consists of very high resolution (VHR) panchromatic and multispectral satellite imagery (WorldView-2, WorldView-3, and QuickBird-2) which were then pan-sharpened. Building footprints were then extracted from the pan-sharpened imagery using Esri pretrained Mask R-CNN deep learning models within ArcGIS Pro. The Africa Building Footprint Extraction model was applied at Solomon Islands and Fiji sites; the USA Building Footprint Extraction model was applied at Papua New Guinea sites. Post-processing steps applied to all output layers include: removal of small detections below 12 square meters, geometric regularization, and systematic manual QA editing comprising deletion of false detections, manual digitizing of missed buildings, and splitting of merged multi-building polygons. All footprint layers were geometrically adjusted to a common 2025 reference frame using a matched-pair median translation approach. A companion settlement growth analysis workbook (Settlement_Growth_Analysis.xlsx) provides derived metrics for each site and epoch, including building count, density, built-up coverage ratio, mean and median building size, and compound annual growth rates. This release includes 18 building footprint shapefiles, six study site boundary shapefiles, and the growth analysis workbook. Users are advised to consult the accompanying Data Use Notes document before use.",

This model was originally developed in 2007, by Petkewich and Campbell (https://pubs.usgs.gov/publication/sir20075126), then updated and recalibrated to conditions from 1900 to 2015. Results of six previous scenario simulations (scenarios 1-6) for the Mount Pleasant Water Works are published in a U.S. Geological Survey (USGS) Scientific Investigations Report (https://doi.org/10.3133/sir20175128). The archived model input and output files are available in a USGS data release (https://doi.org/10.5066/F7S181FC). Seven additional MODFLOW-2000 scenarios (numbered 7-13), using this updated and recalibrated model, were developed to evaluate different withdrawal strategies which are included in this data release: (7) Mount Pleasant Waterworks bringing online a new well (located at the old well 5 location) at 3.51 million gallons per day (Mgal/d) in 2025; (8) Maximizing withdrawals from Mount Pleasant Waterworks wells 2 and 5 (3.51 Mgal/d each) in 2020 and 2025, respectively; (9) Same as Scenario 7, but removing well 3 from production in 2025; (10) Same as Scenario 9, but removing well 4 from production in 2025 (11) Same as Scenario 7, but converting well 3 to an injection well in 2025 (12) Same as Scenario 11, but converting well 4 to an injection well in 2030; and (13) Same as scenario 8, but with two injection wells added (one in 2025 and one in 2035) to Mount Pleasant Waterworks well field. Nine alternate simulations for scenarios 11-13 (three MODFLOW and six MODPATH) were done to evaluate the effects of different porosity on the groundwater flow system, water levels, and the time-of-travel of particles from injection wells to the main water source. This USGS data release contains all the input and output files for the simulations described above and in the readme.txt file of this data release (https://doi.org/10.5066/P9GZEE4E).\n",

Developed through collaboration between the U.S. Geological Survey (USGS) and the Asian Development Bank (ADB), the report synthesizes precipitation, evapotranspiration, and water‑balance data derived from IMERG (Integrated MultisatellitE Retrievals for GPM) and SSEBop (operational Simplified Surface Energy Balance) satellite products to characterize freshwater availability and climate variability in regions with limited ground monitoring. It also describes the development of a monthly drought‑monitoring product and a 7‑day precipitation forecasting workflow to support hydrologic risk assessments. In addition, a deep‑learning‑based approach to extracting multi‑temporal building footprints in informal settlements provides insights into urban expansion and vulnerability to water supply and distribution systems. Seismic assessments offer context for geophysical hazards that may influence water security and infrastructure risk. Collectively, these analyses provide a comprehensive foundation for understanding hydrologic stress, environmental hazards, and community resilience across Micronesia and Melanesia.",
