Water level and barometric pressure measurements in two salt marshes, Humboldt Bay, CA, 2016-2019

Water levels are an important driver of salt marsh processes. In Humboldt Bay, CA, water-level data loggers were deployed in the tidal channels of two USGS study marshes (Mad River marsh and Hookton marsh). From 03/16/2016 to 12/08/2016, Onset-Hobo loggers (Model U-20-001-01-Ti, Onset Computer Corp., Bourne, MA, USA; +/-0.5cm or 0.005 meters accuracy), with a combined barometric pressure sensor, were deployed. The Hobo loggers were replaced by higher accuracy Solinst-Edge LT water-level and Barologgers (Model 3001, Solinst Canada Ltd., Georgetown, Ontario, Canada; +/- 0.3 cm or 0.003 meters accuracy) which were deployed from 12/08/2016 to 09/05/2019. The water-level sensors were placed as low in the tide frame as possible, while still maintaining access to the sensors at low tide. The sensors captured water levels during high tides; but sensor elevations were too high to capture water levels during low tides. The Solinst water-level loggers, deployed in the two study marshes, were programmed to record continuous measurements of absolute pressure, air temperature, and water temperature on a 6-minute timestep. A single barometric pressure logger can be used to correct water-level data within a 30km radius and/or 300 m change in elevation. A single Solinst barometric logger, deployed at the USFWS Humboldt Bay Wildlife Refuge Complex Headquarters Office (https://www.fws.gov/refuge/humboldt-bay), and recorded barometric pressure on a 6 -minute timestep. Following deployment, sensor elevations were surveyed using Real-Time Kinematic GPS (Leica GS-15, Leica Geosystems, Norcross, GA, USA) relative to the North American Vertical Datum of 1988 (NAVD88). The water-level height data collected at Hookton and Mad River marshes was atmospherically corrected using the barometric data. The corrected water-level height data were converted to water-level elevations relative to NAVD88.

Surface deposition and elevations in five salt marshes, Humboldt Bay, CA, 2013-2019

Elevation change and surface deposition are important drivers of salt marsh ecological processes and represent two of the fundamental variables for determining marsh resilience to sea-level rise. Surface Elevation Tables with Marker Horizons (SET-MHs) were used to measure plot-scale elevation change (SETs) and surface deposition (MHs) in five USGS study marshes located in Humboldt Bay, CA. SET-MHs were installed in 2014 (Mad River marsh and Manila marsh) and in 2015 (Jacoby marsh, White marsh, and Hookton marsh) and were measured during quarterly site visits. The SET-MH network includes two SETs and six MHs in each of the five study marshes. Measuring elevation change at the two SETs in each study marsh involves attaching a SET reader (an arm with 9 pins) to a receiving collar that is located on top of a permanent benchmark installed by inserting a deep rod into the marsh surface. Nine pins are lowered to the surface in four ninety-degree cardinal directions (0, 90, 180, 270) yielding 36 measurements of elevation for each SET. The SET method produced 72 quarterly measurements in each of the five marshes. Measurement of the six MHs in each study marsh entails removing a small plug of soil using a soil knife, measuring the depth of surface deposition above the feldspar layer on four sides, and replacing the plug. The MH method produced 12 quarterly measurements in each of the five marshes. The SET-MHs were measured with a ruler to the nearest millimeter by a trained technician.

U-Pb zircon data for Cenozoic clastic and volcaniclastic units deformed along the Gales Creek Fault zone, northwestern Oregon

This data release includes laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) U-Pb zircon geochronology data from four samples collected from fault-bounded bedrock units in northwestern Oregon. Samples were collected from a paleoseismic trench excavated across the Scoggins Valley strand of the Gales Creek Fault and nearby quarry. The trench is located on a ridge top saddle on the Scoggins Creek-Tualatin River divide, where it crosses a lidar scarp trending 300°, up to the east, with suggestion of dextral slip. Trench trends 060° across scarp, is 35 m long in bedrock. Loess, paleosols, and colluvium overlie bedrock. The trench exposes tuffaceous sediments of the Keasey Formation, which records initial deposition of Cascade-derived sediment into the forearc basins from the newly formed Cascade arc. Three samples were collected in the trench from the tuffaceous mudstone of the Keasey Formation; the basaltic sandstone in the Stimson Mill member of the Keasey Formation, and a lithic sandstone bed in the Keasey Formation, respectively. One sample was collected from a quarry near the paleoseismic trench, in a 13m-thick, indurated silicic tuff bed of the Keasey Formation, which may correlate with one of the large, dated ash flow tuffs recognized in the Cascade arc and backarc between ~41 and 25 Ma. The sequence is capped with modern gray loess-derived soil of variable thickness. Ages of samples WN17-1, -2, and -7 overlap, and all have a large tuffaceous component from the initiation of Cascade arc volcanism. Sample WN17-6 has a slightly older detrital age spectra and is a dark brown weathered lithic (basaltic) sandstone, distinct from the three other light colored tuffaceous rocks. The tuff bed (sample WN17-7) is a local marker bed in the basaltic sandstone. The older age for the basaltic sandstone may reflect a separate Coast Range source. The data supports the geologic map of Scoggins Dam, Henry Hagg Lake, and the Scoggins Valley area, Washington County, Oregon.

Documented known and probable grizzly bear mortalities in the Greater Yellowstone Ecosystem, 2015-2024 (ver. 4.0 May 2025)

The Interagency Grizzly Bear Study Team (IGBST) evaluates mortalities for population segments within the DMA by deriving estimates of total mortality for independent-age (2 years or older) females and independent-age males, including estimates of unknown/unreported mortalities based on Cherry et al. (2002). We then determine the total annual mortality rate for these segments as a percent of their respective population estimates. For dependent-age bears (less than 2 years old), we determine the percent of human-caused mortality relative to size of the population segment but do not include estimates of unknown/unreported mortality. Mortality data in this data release represent the individual records documented by the Interagency Grizzly Bear Study Team on an annual basis. Included are all mortality records since 2015. Earlier mortality records can be obtained from annual reports from the Interagency Grizzly Bear Study Team.

12-Digit Hydrologic Unit Outlet Locations for Selected Watersheds Draining to the Gulf of Mexico in the South-Central and Southeastern United States, Derived from the USGS Watershed Boundary Dataset (dated August 13, 2020) and NHDPlus version 2.1

This USGS data release includes a shapefile of outlet point locations for selected 12-digit hydrologic units (HU12s) from the Watershed Boundary Dataset (WBD), dated August 13, 2020 (U.S. Geological Survey and others, 2020), draining to the Gulf of Mexico in the south-central and southeastern United States. The outlet locations were derived by combining the WBD boundaries with flow direction grids from the National Hydrography Dataset Plus (NHDPlus) v 2.1 (U.S. Environmental Protection Agency and U.S. Geological Survey, 2012). Most of the outlet locations were determined by finding the cell with highest flow accumulation from the NHDPlus flow-direction grids within each WBD HU12 boundary. Some locations were found to be inaccurate upon inspection, and other sources were used for the locations as described in the attribute description and process description sections of this document. A shapefile of the HU12 boundaries from the WBD (U.S. Geological Survey and others, 2020) for the study area also is included in this data release for comparison to outlet locations.

Satellite-based barrier island habitat maps, Caminada Headland, Louisiana, 2012–2019 (ver. 2.0, December 2022)

This product is a satellite-based habitat map time series from 2012 to 2019 for the Caminada Headland reach of the Louisiana Gulf shoreline to facilitate monitoring of the National Fish and Wildlife Foundation (NFWF) Caminada Headland Beach and Dune Restoration Incr2 project area (BA-0143). The project restored 489 acres of beach and dune habitat along more than seven miles of Caminada Headland in Jefferson and Lafourche Parishes in Louisiana through the direct placement of about 5.4 million cubic yards of sandy substrate from Ship Shoal. For more information on this restoration project, see the project page on Louisiana Coastal Protection and Restoration Authority’s (CPRA) Coastal Information Management System (https://cims.coastal.la.gov/outreach/projects/ProjectView?projID=BA-0143).
The time period for these maps spans before, during, and after the restoration project. These maps were produced using a random forest model that classified cover types (that is, bare, herbaceous vegetation, woody vegetation, and water) based on spectral indices from Sentinel-2 and Landsat 8 imagery. These products complement habitat maps that were developed from orthoimagery and elevation data using a detailed 15-class habitat scheme developed by the CPRA’s Barrier Island Comprehensive Monitoring (BICM) Program. The BICM Program uses both historical data and contemporary data collections to assess and monitor changes to barrier islands. Habitat map products are one type of BICM dataset. For more information about the BICM Program, see Kindinger and others (2013); for more information about recent BICM habitat mapping, see Enwright and others (2020).
These habitat maps were utilized with ecological data in an analysis of avian habitat occupancy and use/function for several focal species pre- and post-restoration activity. The results of this analysis will help land managers evaluate how restoration and subsequent natural ecological processes impact bird species of conservation concern, and target restoration activities that enhance island sustainability and preserve avian habitat availability.
