AA_Q22.TIF - Aleutian Arc U.S. EEZ GLORIA sidescan-sonar data mosaic (22 of 31) (LCC, 50 m, WGS84)

During late July through September 1987 and June and July 1988 the U.S. Geological Survey (USGS) conducted four cruises to cover the U.S. Exclusive Economic Zone (EEZ) region of the Aleutian Arc. As in earlier EEZ reconnaissance surveys, the USGS utilized the GLORIA (Geological LOng-Range Inclined Asdic) sidescan-sonar system to complete the geologic mapping. The collected GLORIA data were processed and digitally mosaicked to produce continuous imagery of the seafloor. A total of 31 digital mosaics of a 3 degree by 3 degree (or smaller) area with a 50-meter pixel resolution were completed for the region.

Katahdin Woods and Waters National Monument Seboeis Unit Vegetation Mapping Project: Vegetation Map Polygons

The Katahdin Woods and Waters National Monument Seboeis Unit Vegetation Mapping Project was initiated in the fall of 2019 by a grant through the USGS Natural Resource Preservation Program to classify and map vegetation types of the Seboeis Unit thereby providing resource managers and biological researchers with useful baseline vegetation information. This layer provides the vegetation map for the Seboeis Unit. Information for this layer was collected in 2019 and 2020. After completion of the accuracy assessment process, 33 map classes represent the Seboeis Unit of the monument. Of the 33 map classes that represent the Seboeis Unit, 28 represent natural (including ruderal) vegetation types, consisting of 50 U.S. National Vegetation Classification (USNVC) association types. For the remaining 5 of the overall 33 map classes, 2 represent USNVC cultural types for barren areas and developed areas and 3 represent non-USNVC types for non-vegetated open water. Of the 28 map classes representing natural (including ruderal) vegetation types, 15 represent a single vegetation type (when it exists above an the minimum mapping unit [MMU]), 7 represent 2 vegetation types mapped together, 5 represent 3 vegetation types mapped together, and 1 represents 6 vegetation types mapped together. Polygon units were mapped to either a 0.5 ha or 0.25 ha minimum mapping unit, depending on vegetation type. 
Collectively, the spatial-database layer (vegetation map) produced for the Seboeis Unit vegetation mapping project consists of 1,261 polygons and covers 4,854.8 ha, with an average polygon size of 3.8 ha. The 28 map classes representing natural (including ruderal) vegetation types apply to 97.6% of polygons (1,231 polygons; average size of 3.9 ha) and cover 98.6% of the Seboeis Unit (4,787.5 ha). Further broken down, map classes representing natural vegetation types indicate that the Seboeis Unit is 93.2% forest and woodland (4,526.6 ha), 4.0% shrubland (195.3 ha), and 1.3% herbaceous cover (65.6 ha). Map classes representing cultural vegetation types in the USNVC apply to 1.0% of polygons (12 polygons; average size of 2.5 ha) and cover 0.6% of the Seboeis Unit (29.7 ha). Map classes representing non-vegetation open and flowing water (non-USNVC) apply to 1.4% of polygons (18 polygons; average size of 2.1 ha) and cover 0.8% of the Seboeis Unit (37.4 ha).
The information in this layer is explained in depth in the report titled Vegetation Map for the Seboeis Unit of Katahdin Woods and Waters National Monument.

Hourly GPS locations, associated habitat condition, and annotated life history state for training machine learned models of waterfowl daily activity

These data represent an annotated training data for machine learned life history classification of the daily activity of dabbling ducks (f. Anatidae sf. Anatinae) using hourly GPS data.  Each row of data represents a single GPS location for one of 5 species of dabbling duck. Note: the machine learned model was developed to be general across sf. Anatinae and does not include specific reference to the species included. That information is obtainable from the point of contact upon request.  Each data record contains unique identifiers for individual bird, individual date of locations for an individual bird, and for individual location.  Each record contains spatial, temporal and associated habitat information.  Each record also contains an annotated label representing one of 8 life history states or movement patterns exhibited by the collective location obtained for the individual on that date.  The 8 classes identified were: Brooding, Dead, Local movements, Migration, Molting, Molt-Like, Nesting, Regional Relocation. Detailed description of the machine learned model and annotation methods are provided in the associated manuscript titled, Machine learned daily life history classification using low frequency tracking data and automated modelling pipelines: Application to North American waterfowl.

Historical Ice Breakup Dates for Chequamegon Bay, Lake Superior (ver. 5.0, September 2022)

Ice breakup dates of Chequamegon Bay, Lake Superior from 1911 to 2022 were compiled by Lori Evrard (USGS, GLSC, Lake Superior Biological Station, Ashland, WI).  Ice breakup date is the day in spring when winter ice cover substantially leaves a water body.  Local residents deem "ice breakup" as when the ice moves northeast of a line straight across Chequamegon Bay out from Ellis Avenue (State highway 13).  Another way ice breakup was determined has been if you could drive a boat from the outlet of Fish Creek to Houghton Point.  The ice may move back and forth over that line but the ice is breaking up, moving and melting from that date on.  Ellis Avenue ends on a bluff (46.5925 degrees North, 90.8827 degrees West) that provides a clear view of Chequamegon Bay from Fish Creek to Houghton Point.  Mrs. C. J. Hoskings recorded the dates from 1911 to 1980.  Mr. LeRoy C. Margenau recorded the dates from 1981 to 1991.  The Ashland Marina recorded the dates from 1992-1999 and 2001.  Lori Evrard (USGS) recorded dates after 1999 except 2001.  USGS converted each date to a consecutive day of the year value.  The date of ice breakup will be updated annually to append that year's date.

Sagebrush restoration under passive, planting, and seeding scenarios following fire disturbance in the Virginia Mountains, Nevada (2018)

We evaluated the expected success of habitat recovery in priority areas under 3 different restoration scenarios: passive, planting, and seeding. Passive means no human intervention following a fire disturbance. Under a planting scenario, field technicians methodically plant young sagebrush saplings at the burned site. The seeding scenario involves distributing large amounts of sagebrush seeds throughout the affected area.

Diel and synoptic sampling data from Boulder Creek and South Boulder Creek, near Boulder, Colorado, September–October 2019

Multiple sampling campaigns were conducted near Boulder, Colorado, to quantify constituent concentrations and loads in Boulder Creek and its tributary, South Boulder Creek. Diel sampling was initiated at approximately 1100 hours on September 17, 2019, and continued until approximately 2300 hours on September 18, 2019. During this time period, samples were collected at two locations on Boulder Creek approximately every 3.5 hours to quantify the diel variability of constituent concentrations at low flow.
Synoptic sampling campaigns on South Boulder Creek and Boulder Creek were conducted October 15-18, 2019, to develop spatial profiles of concentration, streamflow, and load. Numerous main stem and inflow locations were sampled during each synoptic campaign using the simple grab technique (17 main stem and 2 inflow locations on South Boulder Creek; 34 main stem and 17 inflow locations on Boulder Creek). Streamflow at each main stem location was measured using acoustic doppler velocimetry.
Bulk samples from all sampling campaigns were processed within one hour of sample collection. Processing steps included measurement of pH and specific conductance, and filtration using 0.45-micron filters. Laboratory analyses were subsequently conducted to determine dissolved and total recoverable constituent concentrations. Filtered samples were analyzed for a suite of dissolved anions using ion chromatography. Filtered, acidified samples and unfiltered acidified samples were analyzed by inductively coupled plasma-mass spectrometry and inductively coupled plasma-optical emission spectroscopy to determine dissolved and total recoverable cation concentrations, respectively.
This data release includes three data tables, three photographs, and a kmz file showing the sampling locations. Additional information on the data table contents, including the presentation of data below the analytical detection limits, is provided in a Data Dictionary.

Electrical resistivity tomography in the Air Force Research Laboratory Northeast AFRL and Arroyos Groundwater Areas, Edwards Air Force Base, California 2022

The U.S. Geological Survey (USGS) and Air Force Civil Engineering Center (AFCEC) have entered into a cooperative agreement to refine the hydrogeology in the Northeast AFRL and Arroyos groundwater areas of the Air Force Research Laboratory of Edwards Air Force Base. As part of these efforts, two electrical resistivity tomography (ERT) surveys- AFRL9 and AFRL10- were collected in the vicinity of the Mound Fault identified by Cyr and Miller (2022) to better determine the position of these faults. 
Electrical resistivity tomography is a direct current geophysical method that is used to estimate the subsurface distribution of the electrical resistivity (measured in ohm-meters; ohm-m) of a material, and is based on the assumption that measured electric potentials (voltages) near current carrying electrodes are influenced by the electrical resistivities of the underlying material (Zohdy and others, 1974; Loke, 2000). ERT is a popular technique for subsurface investigations because it is based on simple physical principles and for its efficient data acquisition (Dahlin and Zhou, 2004). 
A combination of the Dipole-Dipole and Strong Gradient arrays was used for this survey and combined to create an optimized dataset (Stummer and others, 2004). The Dipole-Dipole array type yields a high precision dataset, particularly of vertical structures, but can exhibit lower signal to noise ratios (Dahlin and Zhou, 2004; Binley and Kemna, 2005), while the Strong Gradient array provides more complete spatial coverage, and high signal to noise ratio with increased acquisition efficiency (Dahlin and Zhou, 2004; Dahlin and Zhou, 2006, Advanced Geosciences Inc., 2009).

Pesticide Concentrations Measured in Zooplankton Samples Collected from the Sacramento River and Yolo Bypass, California, 2021

Zooplankton samples were collected at one site upstream of the Yolo Bypass in Northern California, three sites within the Bypass, and at a comparison site on the Sacramento River below the city of Sacramento and analyzed for a large suite of current-use pesticides and degradates. Samples were collected every two weeks from early August 2021 to mid-October 2021. Samples were collected by towing a 150-micron conical plankton net for 5 minutes by boat at each site. In the laboratory, zooplankton samples were filtered through a 63-micrometer sieve to separate the zooplankton and vegetation/detritus from the water. Large sticks, twigs, rocks, and leaves were rinsed with organic free water into the sieve and then discarded. The remaining mass in the sieve was transferred into 50 milliliter plastic centrifuge tubes, frozen overnight at -20 degrees Celsius, dehydrated completely using a freeze dryer, and then stored at -20 degrees Celsius. Immediately prior to analysis, each freeze-dried sample was homogenized and sub-sampled to a targeted final weight of 0.5 grams. Sub-samples were further homogenized with magnesium sulfate and extracted with acetonitrile at 100 degrees Celsius using an EDGE Automated Extraction System. Extracts were cleaned up using activated carbon and evaporated to 200 microliters in acetonitrile. Each sample had internal standards added, and was analyzed by gas chromatography-tandem mass spectrometry for 29 pesticides and by liquid chromatography tandem mass spectrometry for 137 pesticides. A total of 18 pesticides were detected in the zooplankton samples, and 25 of the 31 samples collected contained multiple pesticides (maximum of 12 per sample). The most frequently detected compounds in zooplankton were azoxystrobin, bifenthrin, fluridone, p,p’-DDD, p,p’-DDE, permethrin, and thiobencarb.

Data Used to Calculate Flow Logs for Wells in the Wilson Creek and Crafton Subareas, Yucaipa, California, 2004

This dataset contains velocity and flow log data collected in 2004 for two Yucaipa Valley Water District (YVWD) public-supply wells, YVWD 55 and YVWD 56. Data were collected using the tracer-pulse method described in Izbicki and others (1999), in which a pulse of a rhodamine dye tracer is injected to a known depth in the well and the travel time of the tracer to a detector on the surface is measured. Velocity and cumulative flow are calculated from the dye-arrival times using methods described by Izbicki and others (1999). Flow for well YVWD 55 was calculated using the pump within the screened interval, which captured flow from above and below the pump intake. Flow for well YVWD 56 was calculated using the pump above the screened interval and all flow was upward. Included in this release are two tables with dye-arrival times, two tables with velocity- and cumulative-flow log calculations, and a table of relevant well properties. These data support the interpretations and conclusions in Cromwell and others (2022) and Alzraiee and others (2022).
