Coastal management decisions are complex and include challenging tradeoffs. Decision science offers a useful framework to address such complex problems. We illustrate the process with several coastal restoration studies. Our capstone example is based on a recent barrier island restoration assessment project at Dauphin Island, Alabama, which included the development of geomorphological and ecological models that forecast environmental changes over a 10 year time period from 2015 to 2025. The proposed framework aims to serve as a tool to assist coastal managers with the process of restoration. Specifically, we discuss the importance of considering concepts and techniques from ecology, coastal geology, geomorphology,...

These data were released prior to the October 1, 2016 effective date for the USGS’s policy dictating the review, approval, and release of scientific data as referenced in USGS Survey Manual Chapter 502.8 Fundamental Science Practices: Review and Approval of Scientific Data for Release. This dataset represents 19,031 basin boundaries and their streamgage locations for the U.S. Geological Survey's (USGS) active and historical streamgages from the published dataset of Stewart and others (2006) and its subsequent updates (D.W. Stewart, USGS, written commun., 2011). Only the basin boundaries that were delineated within 15 percent of the basin area reported in the National Water Information System (NWIS) were included...
The U.S. Geological Survey, in cooperation with Colorado Springs Utilities, has been collecting topographic data annually since 2012 at 10 study areas along Fountain Creek, Colorado. The 10 study areas are located along Fountain Creek between Colorado Springs and the confluence of Fountain Creek and the Arkansas River in Pueblo. This data release presents topographic survey data, Light Detection and Ranging (lidar) survey data, elevation rasters, and elevation-change rasters collected or generated in 2024 as part of that monitoring effort. Topographic survey points were collected using real-time kinematic Global Navigation Satellite Systems (RTK-GNSS). These point data, along with lidar point clouds, were used to...
The data release consists of two companion air and water temperature datasets collected as part of the U.S. Geological Survey (USGS) Next Generation Water Observing System (NGWOS) program with data from both the Little Lehigh and White Clay Creek Watersheds in the Delaware River Basin.

Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, SMC, UWE) from January 1 to December 31, 2022. These data were collected in 2022 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory.
The data included here were used to evaluate the prospectivity for lithium in brines of playas of the western part of the Basin and Range Physiographic Province of the United States. Prospectivity is derived from the mappable criteria used in the descriptive deposit model published by Bradley and others (2013) and focused mainly from the remote sensing point of view. The playas in the study area have been ranked according to size (compared to Clayton Valley, the only area where lithium from brines is being produced in the country), the presence and abundance of source rocks, vegetation (as an indicator of water), reported prospects, and remote sensing data. The remote sensing products used are from data acquired...
This data release contains measured stream discharge and total dissolved solids (TDS) data and estimated values for daily stream TDS loads, daily baseflow discharge, and daily baseflow TDS loads for 205 locations in the Upper Colorado River Basin. The estimated values, which represent conditions between 10/1/1985 and 9/30/2020, were obtained using the Weighted Regressions on Time, Discharge, and Season (WRTDS) program and a previously published method for hydrograph separation.
Slug additions are often the most accurate method for determining discharge when traditional current meter or acoustic measurements are unreliable because of high turbulence, rocky streambed, shallow or sheet flow, or the stream is physically inaccessible (e.g., under ice or canyon walls) or unsafe to wade (Zellweger et al., 1989, Kilpatrick and Cobb 1984, Ferranti 2015). The slug addition method for determining discharge requires an injection of a known amount of a single salt and high-frequency downstream measurement of solute concentration to capture the response curve (Kilpatrick and Cobb 1984). A new slug method was developed to determine stream discharge utilizing specific conductance and ionic molal conductivities...

The Aransas-Wood Buffalo population of whooping cranes migrates through the U.S. Great Plains twice annually, moving between wintering areas along coastal Texas and summering areas in and around Wood Buffalo National Park, Canada. These data support development of resource utilization functions that were used to predict wintering use of whooping cranes outside of their historic coastal wintering areas.

Unprecedented wildfire frequency fueled by invasive annual grasses threatens sagebrush habitats. To suppress fire and conserve sagebrush, land management agencies have installed ~10,000 km of fuel breaks across the sagebrush ecosystem. The ecological risks and benefits of creating fuel breaks for wildfire suppression are unquantified but must be balanced to avoid accelerating sagebrush loss, annual grass invasion, and habitat degradation. To begin to evaluate ecological trade-offs, we characterized the contexts in which known fuel breaks exist. Weise et al. (2024) compiled the spatial footprints of fuel breaks across the western United States from the land treatment digital library (LTDL; Pilliod and Welty 2013),...
This data release makes available the data used to test a method for remote sensing of river discharge based on critical flow theory. In rivers where flow conditions are near critical and well-defined standing waves are present, simple measurements of the wavelengths of the standing waves and the width of the channel made using readily available image data can be used to infer river discharge. This approach could provide an efficient, non-contact method of estimating streamflow in certain rivers. Sites near established USGS gaging stations with standing waves (also known as undular hydraulic jumps) were identified by examining images within Google Earth Pro (https://www.google.com/earth/about/versions/#earth-pro)....

These data are comprised of beryllium-7 (7Be) and excess lead-210 (210Pbxs) activity for fine-grained, mobile, streambed sediment at seven reaches in the Little Flatrock Creek stream-channel network. This basin is monitored in cooperation with the Ohio Department of Natural Resources. During the period July 26-27, 2019 (summer low flow), the thickness and spatial extent of soft, mobile, fine-grained (mainly silt and clay) streambed sediment was inventoried and sampled along 150-meter (m) transects. A combination of stream corridor land-use distribution, valley type, channel slope, and stream order (Strahler, 1957) was used to select 15 rapid geomorphic assessment reaches using methods of Fitzpatrick and others (2016);...
This data release contains the model inputs, outputs, and source code (written in R) for a redeveloped PRObability of Streamflow PERmanence (PROSPER) model (version 2.1) that had previously been developed for the Pacific Northwest Region (PROSPER_PNW_2), and a raster data set which shows where influential predictor values were outside the range of calibration data. The PROSPER-PNW version 2.1 model, a random forest model, was redeveloped in the Ranger R package using all the original model inputs consistent with PROSPER_PNW_2 to produce annual streamflow permanence probabilities for calendar years 2004-2016 at a 30-meter stream grid resolution that approximately corresponds to flowlines consistent with the National...

Annual spring (May) and fall (late October through early November) gillnet assessment surveys were conducted by researchers at the USGS Great Lakes Science Center (GLSC) in northern Lake Michigan, including the Northern Refuge, between 1998-2023. Total length, weight, sex, maturity, and sea lamprey wounds were recorded for each lake trout and burbot caught in the gill nets. Lake trout were aged: (1) by decoding information on an extracted coded wire tag; (2) using fin clip information; or (3) enumerating annuli on a maxilla bone. Burbot were aged by enumerating annuli on an otolith. Catch of both lake trout and burbot have been recorded for each of the gill nets that have been set. To study the dynamics of the lake...

Note: This data release has been preceded by version 1.0, available here: https://doi.org/10.5066/P97KZJGP. The data release presents observations of riparian vegetation, topography, and sediment quality in five river reaches of the Lower Virgin River extending downstream 62 river kilometers (rkm), from near the town of Littlefield (Arizona) to approximately 15 rkm upstream from the confluence with the Muddy River (Nevada). Methods included field observations and analysis of the plant community before substantial biocontrol-induced dieback of invasive Tamarix spp. shrubs (surveys in 2010 and 2012) and after (surveys in 2015, 2017, and 2021). The first survey was conducted before a 40-year return period flood (December...
Recent work in the Great Basin region of the western United States has made it possible to predict the depth of hydrothermal reservoirs (i.e., the depth at which heat is accumulated prior to ascent via hydrothermal upflow) identified through geochemistry and to contextualize the spatial patterns of these reservoir depths. Chemical geothermometers use the chemical and mineral constituents of hydrothermal fluids to predict the temperature at which fluids equilibrated with the host rocks at depth. Assuming that most of the Great Basin is dominated by conductive conditions until a vertically connected hydrothermal flow path is created (e.g., by faulting), geothermometers reflect the chemical and thermal conditions at...
