Data for the development of a new method for dynamically estimating exposure time for turbulent flow measurements

The mission of the U.S. Geological Survey (USGS) involves providing reliable, impartial, and timely information that is needed to understand the Nation’s water resource.  New techniques that aid in achieving this mission are important, especially those that allow USGS to do so more accurately or cost-effectively.  To this end, a new method for selecting the optimum exposure time for velocity and discharge measurements has been explored.  These data were assembled to assist in the development and evaluation of this new method.   Four kinds of time-series data are available and used for this purpose.  They are: (1) model-derived synthetic velocities, (2) point-velocity measurements in laboratory flumes, (3) point-velocity measurements in streams, and (4) water velocity profile measurements in streams.  The model-derived velocity data were obtained using methods described in Garcia and others (2005).  Point-velocity flume measurement data were obtained using a Nortek 16 MHz acoustic Doppler velocimeter (ADV) for the purpose of characterizing turbulence in the flow in a flume.  Point-velocity measurement data collected in the field were obtained using a SonTek Flowtracker ADV (1 MHz) and an OTT acoustic Doppler current meter or ADC (6 Mhz) as a part of routine mid-section discharge measurements.  Water velocity profile measurements in streams were collected using SonTek and Teledyne RD Instruments Acoustic Doppler current profilers (ADCPs) during routine mid-section discharge measurements. 
The laboratory ADV data were collected, processed, and exported using the associated ADV software.  Data are provided in the zip file, ‘DynamicExpTime.zip’ which contains 4 types of times series data.  The model-derived velocities are provided in a spreadsheet format. The ADV, ADC, Flowtracker, and ADCP data were exported from their native file formats and are provided in comma-separated value and ASCII text files.

Strata boundaries for nesting Wedge-tailed Shearwater (Ardenna pacifica) surveys at Kīlauea Point National Wildlife Refuge, Kauaʻi, in 2019

We used a stratified-random sampling approach to estimate the total abundance of Wedge-tailed Shearwater (Ardenna pacifica) nest sites across Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi, during 1-7 July 2019. We first identified strata as unique geographic areas of the refuge to account for potential differences in nesting habitat and non-uniform nest site clustering. We then sub-divided strata where we expected high, low, minimal, or no nest site abundance. These distinctions were based on knowledge of shearwater nesting distribution gained while performing extensive ground-searching for tropicbirds across the entire refuge in April and May 2019. We delineated strata boundaries using recent satellite imagery in ArcGIS (version 10.7) and, based on direct observations in the field, refined in order to remove large contiguous areas lacking shearwater presence or nesting habitat. Planar area of each polygon was automatically calculated by ArcGIS. To calculate surface area in each stratum, we obtained a 1/3 arc-second (10-m resolution) digital elevation model from the National Elevation Dataset (USGS 2013). This elevation raster was projected to Universal Transverse Mercator projection (Zone 4 North, North American Datum 1983) and converted to a surface area raster using the raster and sp packages in R (Hijmans 2019; Pebesma &amp; Bivand 2005). We calculated stratum-specific surface area by summing the surface area values of raster cells in each stratum using XToolsPro (version 18; Zonal Statistics tool) in ArcMap (version 10.7).

Soil microbes surrounding native and non-native Phragmites australis in the Great Lakes and East Coast of the United States (2015-2017 survey). (ver. 1.1, December 2020)

To determine the differences in soil microbial community composition between native and non-native lineages of Phragmites, we sampled soils from eight sites in the Great Lakes basin where populations of native and non-native Phragmites co-occurred. In addition, we included samples of soils from 27 populations of Phragmites across the Gulf of Mexico and Atlantic Coasts of the US. Samples were collected between July 2015 and September 2017. At each site in the Great Lakes, we sampled rhizosphere and bulk soil surrounding one ramet of each lineage. Samples from Atlantic and Gulf coasts were collected by homogenizing rhizosphere soils from multiple ramets of one population within a single lineage. DNA was extracted from soils and fungal, bacterial, and oomycete DNA was amplified to identify the microbial constituents. Amplicons were sequenced using Illumina MiSeq. This dataset includes outputs of bioinformatic analysis of sequences including operational taxonomic unit (OTU) generation, OTU abundance, resolved taxonomy, and environmental metadata collected in our survey. Raw sequences were uploaded to the NCBI Sequence Read Archive under SRA accession number PRJNA601975.

KauaiN_baseline - Offshore baseline used to cast shore-perpendicular transects for measurement of historical shoreline positions along North Kauai, Hawaii (Haena to Moloaa)

Sandy ocean beaches are a popular recreational destination, often surrounded by communities containing valuable real estate.  Development is on the rise despite the fact that coastal infrastructure is subjected to flooding and erosion.  As a result, there is an increased demand for accurate information regarding past and present shoreline changes.  To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is compiling existing reliable historical shoreline data along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii under the National Assessment of Shoreline Change project.
There is no widely accepted standard for analyzing shoreline change.  Existing shoreline data measurements and rate calculation methods vary from study to study and prevent combining results into state-wide or regional assessments.  The impetus behind the National Assessment project was to develop a standardized method of measuring changes in shoreline position that is consistent from coast to coast.  The goal was to facilitate the process of periodically and systematically updating the results in an internally consistent manner.

GPS tracks of ground search effort for nesting Red-tailed Tropicbird (Phaethon rubricauda) and White-tailed Tropicbird (P. lepturus) surveys at Kīlauea Point National Wildlife Refuge, Kauaʻi, in 2019

During 8-11 April, 13-18 May, and 1-7 July 2019, we censused Red-tailed (Phaethon rubricauda) and White-tailed (P. lepturus) tropicbird nests in Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi, by searching all foot-accessible areas and by searching all cliffs and islets with spotting scopes from remote vantage points. We censused over the course of three visits to account for prolonged and asynchronous nesting. For ground searching, we used previous nest census results, recommendations from the previous Refuge biologist, and our knowledge of tropicbird nesting habitat, to focus searches in areas where nesting was likely: along cliff edges and steep slopes, particularly at the base of ironwood trees (Casuarina equisetifolia) and beneath dense shrubs. Within these habitats, we searched the ground as thoroughly as vegetation and topography would permit. In areas that we did not expect to be suitable tropicbird nesting habitat (e.g. flat, open areas far from cliff edges or windward slopes), we scanned the area but did not search as thoroughly as in suspected nesting habitat. We collected continuous, 1-second GPS tracks of search effort at all times and have archived those tracks here.

Nest sites and habitat characteristics for Red-tailed Tropicbirds (Phaethon rubricauda) and White-tailed Tropicbirds (P. lepturus) at Kīlauea Point National Wildlife Refuge, Kauaʻi, in 2019

During 8-11 April, 13-18 May, and 1-7 July 2019, we censused Red-tailed Tropicbird (Phaethon rubricauda) and White-tailed Tropicbird (P. lepturus) nests in Kīlauea Point National Wildlife Refuge (KPNWR), Kauaʻi, by searching all foot-accessible areas and by searching all cliffs and islets with spotting scopes from remote vantage points. We censused over the course of three visits to account for prolonged and asynchronous nesting. For ground searching, we used previous nest census results, recommendations from the previous Refuge biologist, and knowledge of tropicbird nesting habitat, to focus searches in areas where nesting was likely: along cliff edges and steep slopes, particularly at the base of ironwood trees (Casuarina equisetifolia) and beneath dense shrubs. Within these habitats, we searched the ground as thoroughly as vegetation and topography would permit. In areas that we did not expect to be suitable tropicbird nesting habitat (e.g. flat, open areas far from cliff edges or windward slopes), we scanned the area but did not search as thoroughly as in suspected nesting habitat. 
For ground-accessible nests, we assigned a nest number, recorded the GPS location, flagged the nest, and recorded nest contents and habitat type. For inaccessible nest habitat, we used a spotting scope to view remote cliffs and offshore islets for tropicbird nests. For remote sites, we identified tropicbirds to species, recorded the location using a georeferenced satellite image, collected reference photographs for subsequent checks, and recorded habitat type when possible. In May and July, we used locations of nests from previous visits (and reference photographs for remotely viewed sites) to record tropicbird presence at previously identified nest sites and also to assist with searches for newly initiated nests. In July, our last visit, we removed flags after checking previously located nests and recorded, but did not flag, newly initiated nests. On each visit, we classified nest contents and estimated chick age (if present). We also recorded three metrics of nest habitat: the landform the nest was on, the structure of the nest site (e.g., what provides some shade), and the first and second most dominant plant types.

Data Release for the 2016 East Bay Seismic Imaging Investigation of the Hayward Fault Zone

In October 2016, we acquired an approximately 15-km-long seismic profile along a linear transect across the East Bay region of the San Francisco Bay area. Our goal was to image previously unknown strands of the Hayward Fault zone and to better delineate the structure and geometry of the main trace of the Hayward Fault. Our profile started near the southern border of San Leandro, California at the San Francisco Bay shoreline, trended ENE through the northern edge of Castro Valley, California, and ended approximately 5 km WSW of San Ramon, California. The data were analyzed using refraction tomography modeling, reflection processing, and guided-wave analysis. The analyzed data are presented in separate reports by Strayer and others (submitted to BSSA).  
The seismic data were generated at 26 shotpoints: 16 shotpoints located along the profile (inline shotpoints) and 10 shotpoints offset from the profile and located within known or suspected fault traces (guided-wave shotpoints). Most shotpoints used explosive sources to generate the seismic waves, but three of the shotpoints used repeated hits from a 227-kg (500 lb) accelerated weight dropped ~2 feet above a steel plate to generate the seismic signal. Data from each shot were recorded by a total of 459 seismographs, mostly deployed along the profile at intervals ranging from 20 to 100 meters.  
This data release contains the raw field records from all explosive and weight drop shots. The raw field records are in a proprietary Trimble TRD format and consist of continuous seismograph recordings during the time of the data collection. Also included in this data release are multiple SEG-Y files consisting of thirty-second-long traces "cut" from the TRD files and resorted into conventional shot gathers. These data are in standard SEG-Y format, with the data samples in IBM floating point format. Data samples are in units of meters/second, without filtering or other data manipulation.
