U-Pb Isotope Geochronology Data and Geochemical Analyses of Selected Rocks from the Seldovia Quadrangle, Southcentral Alaska

This dataset contains U-Pb isotopic data and associated ages of zircons within the lithologic framework of igneous, metaigneous, and metasedimentary rocks collected from the Seldovia quadrangle in southcentral Alaska. The samples were collected as part of geological mapping and research conducted from 2020 to 2023 and funded by the Mineral Resources Program of the U.S. Geological Survey. Zircon grains were separated and analyzed by GeoSep Services (GSS). All analyses were conducted between 2021 and 2023 using laser-ablation-inductively-coupled-plasma-mass spectrometry (LA-ICP-MS) techniques.
      Also described in this report are the major and trace element geochemical analyses for samples collected as part of the mapping project. Analyses were conducted by ALS Global. Major elements were determined from fused bead, acid digestion, and ICP-AES analysis. Loss on ignition (LOI) was determined by furnace or TGA. Also included are rubidium (Rb), strontium (Sr), samarium (Sm), and neodymium (Nd) analyses conducted by the ALS Scandinavia laboratory in Lulea, Sweden. Samples were prepared by alkali fusion. Sr was separated using Sr-specific column (TrisKem). Nd was separated from matrix first as sum of REE using a AG50-x8 column (AlfaAesar) and then from Sm on a Ln column (TrisKem).

High resolution natural color imagery collected by uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, Utah from 2020-2023.

The U.S. Geological Survey collected low-altitude airborne natural color imagery via a fixed-wing uncrewed aircraft system (UAS) for mapping channel and vegetation change along a 6-mile reach of the Middle Green River at Ouray National Wildlife Refuge near Ouray, UT. Visual imagery was collected in jpg format and Structure-from-Motion (SfM) photogrammetry techniques were applied (Over et al., 2021) using Agisoft Metashape Professional (v. 2.1.2 build 18358) to derive time-specific high-resolution 5 centimeter natural color orthomosaics of the study reach annually from 2020 to 2023. Ground control points (2ft x 2ft ground targets) were also surveyed in the field using Trimble RTK GPS survey units and were used in georectification in the SfM process.

LANDFIRE Preliminary Annual Disturbance CONUS 2023

The LANDFIRE Preliminary Annual Disturbance (PDist)23 product is a new product introduced with the LF 2023 Update (LF 2023). While LDist23 is a first "draft", PDist23 is akin to a second “draft” of the LANDFIRE Annual Disturbance product and includes disturbance events captured through October 31, 2023. PDist23 is releasing for these extents throughout the calendar year 2024: Conterminous United States (CONUS), Alaska (AK), Hawaii (HI), and Puerto Rico and the US Virgin Islands (PRVI). See the LF 2023 page for more information as this page will be added to as more details are available. https://landfire.gov/data/lf2023  
Preliminary Annual Disturbance (PDist23) was created with Landsat imagery, submitted disturbance events from the data call, and online fire program data collected on or before October 31, 2023. Unlike the Limited Annual Disturbance (LDist23) product released earlier in calendar year 2024, PDist23 includes remotely sensed severity for submitted events and unknown disturbances where change was detected.

Contaminants measured in multiple environmental media in the Lake Mead National Recreation Area NV/AZ, USA in 2010

Concentrations of a wide variety of environmental organic contaminants were measured in surface waters of the Lake Mead National Recreation Area (Nevada and Arizona) in 2010 to provide a measure of exposure to resident fish species. These contaminants were sampled using the semipermeable membrane device (SPMD) and the polar organic chemical integrative sampler (POCIS) which allow for the determination of the average contaminant concentrations over a month-long study period.  Contaminants measured included polycyclic aromatic hydrocarbons, polychlorinated biphenyls, organochlorine pesticides, pharmaceuticals, select illicit drugs, and other chemicals related to wastewater treatment plant effluents.  In addition, sediments, periphyton, fish feeds, and other materials from the Willow Beach fish hatchery were screened for polychlorinated biphenyls which are historically present in many hatcheries across the Nation.

Predicting wildlife distribution patterns in New England USA with expert elicitation techniques

Understanding the impacts of landscape change on species distributions can help inform decision-making and conservation planning. Unfortunately, empirical data that span large spatial extents across multiple taxa are limited. In this study, we used expert elicitation techniques to develop species distribution models (SDMs) for harvested wildlife species (n = 10) in the New England region of the northeastern United States. We administered an online survey that elicited opinions from wildlife experts on the probability of species occurrence throughout the study region. We collected 3396 probability of occurrence estimates from 46 experts, and used linear mixed-effects methods and landcover variables at multiple spatial extents to develop SDMs. We applied models to rasters (30 × 30 m pixles) of the New England region to map each species’ distribution. Details of the project can be found in the following publication: Pearman-Gillman SB, Katz JE, Mickey R, Murdoch JD, and Donovan TM. 2020.

Kīpahulu Valley, Haleakalā National Park, Hawai'i, Stream Survey Data, 2022-2023.

As part of a larger study looking at the seasonal distribution and relative abundance of the southern house mosquito Culex quinquefasciatus in Kīpahulu Valley, Haleakalā National Park, terrestrial and stream surveys were conducted to determine the abundance of available larval mosquito habitat and the presence of mosquito larvae within the study area. Terrestrial larval mosquito habitat, like wallows and hapuu cavities, are largely dependent on the presence of feral pigs. Naturally occurring ground pools may be found in bogs and on less permeable, older soils. Stream-associated habitat is dependent more on rocky substrates and stream flow. First order, intermittent flowing streams found at higher elevations are more likely to provide larval habitat. At the higher elevation Palikea site only Aedes japonicus were found in stream pools but at the lower Delta site both Aedes japonicus and C. quinquefasciatus were found in stream pools. Culex quinquefasciatus larvae were also found in a ground pool with the remains of a dead pig at the Delta site.

Downscaled Climate Projections for the Edwards Aquifer Region (EAR) using CMIP6 for the years 2015 – 2100

Global climate models (GCMs) are computationally intensive, physics-based research tools used to simulate the climate system. GCM can also be useful in applied research contexts with the use of statistical downscaling techniques. This collection of statistically downscaled climate projections includes 12 sets of SD-processed CMIP6 projections of daily high temperature, daily low temperature, and daily total precipitation across the Edwards Aquifer Region (EAR) in south central Texas. These sets of projections were created using six GCMs from the CMIP6 archive (EC-Earth3, INM-CM-4-8, INM-CM-5-0, KACE-1-0-G, KIOST-ESM, and MPI-ESM1-2-HR), each of which simulated 21st century climate responses for multiple future emissions scenarios. The CMIP6 GCMs simulated response under the shared socioeconomic pathways (SSPs) 2-4.5 and 5-8.5. The equi-distant quantile mapping method (EDQM) was used for statistical downscaling with the Daymet v. 4 as the observational data used for training. The resulting SD-processed projections are on a 1 km by 1 km grid covering the EAR in south central Texas (100.75 degress E to 97.5 degrees E, 28.75 degrees N to 30.50 degrees N). Both historical baseline files (1980-2014) and future projections (2015-2100) are provided.
Applied researchers may explore aspects of potential changes in the EAR using these high resolution projections, including as inputs to additional modelling (e.g. hydrology modeling, crop modeling, etc.). This collection should not be considered comprehensive in spanning the entire scope of SD processed climate projections for the EAR. These climate projection data products are provided as is without any warranty and no agreement to support subsequent projects based on this dataset, beyond providing the data to public domain.

Landuse / Landcover Map of Los Planes Watershed, Baja California Sur, Mexico

This landuse / landcover (LULC) map displays a basic depiction of the Los Planes watershed in Baja California Sur, Mexico. This simplified, 7-class LULC map displays classes that are useful for hydrologic modeling and broad vegetation mapping in the region.  It was created from analysis of six Sentinel-2 satellite images and other existing geospatial datasets.  These satellite images are provided at 10-meter spatial resolution and were calibrated for topographic illumination effects to enhance its accuracy in rugged, mountainous terrain like that seen in the watershed. A novel filtering methodology was also applied to minimize the "salt-and-pepper effect" from the principle component analysis (PCA) and image classification methodology.  See "lulc_los_planes_watershed_final_2_legend.jpg" for a low-resolution overview of the image and legend.

Patuxent River Basin Environmental Variable Rasters: Climate, Topography, Land Use and Land Cover

Natural resource managers worldwide grapple with protecting aquatic environments and species in the face of intensifying land use and climatic changes. The hierarchical landscape theory suggests that a species distribution is impacted by multiple series of environmental factors affecting the species at multiple spatial resolutions. For a species to inhabit an area, it must pass through these environmental filters similar to a set of sieves. Utilizing this theory as a modeling framework, we created Nested Ensemble Species Distribution Models (NESDMs). This approach assesses species distributions at multiple spatial scales, consecutively limiting the predicted habitat range as it passes through a series of static resolution models that increase in spatial resolution. We found land use/land cover (LULC), climate, and topographic variables were useful in predicting the distribution for all of our focal species (American eel, tessellated darter, and white perch) at each spatial resolutions tested (1000m, 100m, and 10m). The variables that influenced model accuracy changed at finer spatial resolutions and unsuitable areas were removed. Additionally, total area predicted as suitable for all three species assessed was greatly reduced from the area selected at the coarsest resolution (85-90% reduction) to the area selected at the finest resolution. In utilizing the NESDM approach, computation time and processing power were substantially reduced compared to modeling at the entire spatial extent of the study. Modeling accuracy of both individual distribution methods (e.g., Maxent, Random Forest, GLM, etc.) and ensembles of multiple methods showed adequate predictive accuracy based on our model assessment criteria. The demonstrated NESDM framework potentially increases the precision and utility of the final outputs for conservation management and strategic resource allocation. The data describes topographical, climatic, land use and land cover, flow accumulation, watershed influence. 
The data in this released was used in Kiser et al., (2024) Nested Ensemble Species Distribution Models: A Multi-Resolution Approach to Species Distribution Modeling study.

Digital Shoreline Analysis System version 4.3 shoreline intersection points used to calculate long-term shoreline change statistics for the South Cape Cod coastal region from Stage Harbor Light in Chatham to Nobska Point in Woods Hole (SouthCapeCod_intersects_LTw.shp)

Due to continued coastal population growth and increased threats of erosion, current data on trends and rates of shoreline movement are required to inform shoreline and floodplain management. The Massachusetts Office of Coastal Zone Management launched the Shoreline Change Project in 1989 to identify erosion-prone areas of the coast. In 2001, a 1994 shoreline was added to calculate both long- and short-term shoreline change rates at 40-meter intervals along ocean-facing sections of the Massachusetts coast.
The Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) in cooperation with the Massachusetts Office of Coastal Zone Management, has compiled reliable historical shoreline data along open-facing sections of the Massachusetts coast under the Massachusetts Shoreline Change Mapping and Analysis Project 2013 Update. Two oceanfront shorelines for Massachusetts (approximately 1,800 km in total length) were (1) delineated using 2008/09 color aerial orthoimagery, and (2) extracted from topographic LIDAR datasets (2007) obtained from NOAA's Ocean Service, Coastal Services Center. The new shorelines were integrated with existing Massachusetts Office of Coastal Zone Management and USGS historical shoreline data in order to compute long- and short-term rates using the latest version of the Digital Shoreline Analysis System (DSAS).
