Gulf Watch Alaska, Benthic Monitoring Component: Sea Otter Aerial Survey Data Kenai Fjords National Park, 2002-2016

These data  are is part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. Specifically, these data describe sea otter (Enhydra lutris) aerial survey observations from the waters around Kenai Fjords National Park between 2002 and 2016. Sea otters are a keystone predator, well known for structuring the nearshore marine ecosystem through their consumption of invertebrate prey. The dataset consists of 3 comma delimited files exported from Microsoft Excel. The data consists of 1. Strip transect counts, 2. Intensive Search Unit (ISU) counts, and 3. Transect coordinates. For each aerial survey, a pilot flew an airplane at an altitude of 91m over pre-determined transects while an observer searched on one side of the plane and recorded sea otter group counts and locations. Sea otters observed within 400 m of each transect were later used to estimate abundance.  Sea otters sighted beyond the confines of designated transect swaths were also counted and mapped, time permitting.  To estimate the number of sea otters in small groups (&lt;20) not detected along transect swaths (e.g., due to diving behavior or the presence of kelp canopy), 400m diameter circles (i.e. ISUs) were searched intensively by periodically flying 5 concentric circles around an initiating group.  These ISUs were distributed throughout the survey area in an attempt to accurately represent the full range of observation conditions encountered during the survey.  When large groups of sea otters (≥20) were sighted on transect, they were circled until a complete count was made.

Archival data sets for regressions to estimate continuous streamflow, turbidity, and suspended sediment in support of study evaluating effects of removal of legacy sediment at Big Spring Run, Lancaster County, Pennsylvania, 2009-2015

The stream corridor at the Big Spring Run restoration site has been identified as a substantial source of sediment and nutrients to streams due to streambank erosion and floodplain scour of legacy sediment. Three USGS streamgages were installed and water-quality monitoring began in water year 2009, prior to the legacy sediment removal from the restoration area. The legacy sediment was removed from approximately 4.6 acres within the Big Spring Run study area in the fall of 2011. Monitoring has continued in the post-restoration period. This study was conducted in cooperation with the Pennsylvania Department of Environmental Protection, Franklin and Marshall College, and the US Environmental Protection Agency and examines the effects of the legacy sediment removal on nutrients and sediment during the post-restoration monitoring period (Water Years 2012-2015) compared to the pre-restoration monitoring period (Water Years 2009-2011) in the Big Spring Run watershed. The content and connection among files in this product are described in the readme file.

Floating transient electromagnetic (FloaTEM) surveys in the Eel River near Falmouth, Massachusetts

Floating transient electromagnetic (FloaTEM) data were acquired on the Eel River during November 2018. During the survey, approximately 1.6 line-kilometers were collected in the Eel River, Falmouth, Massachusetts study area. Data were collected by members of the U.S. Geological Survey, Hydrogeophysics Branch, and New England Water Science Center. FloaTEM data acquired along the Eel River in Barnstable County, in Massachusetts, were collected to test a new continuous water-borne transient electromagnetic data collection platform, and to characterize the subsurface resistivity structure in support of a U.S. Geological Survey groundwater investigation of the Falmouth, Massachusetts area. FloaTEM data were collected using an Aarhus University HydroGeophysics Group FloaTEM unit using a transmitter loop (Tx) size, 4 by 2 meter square (m^2), in an offset-loop receiver (Rx) configuration utilizing a receiver coil that is 0.5 by 0.5 m^2 in size (with an effective area of 35 m^2) towed about 7 meters behind the Tx loop. The Tx outputs dual currents of about 3 and 30 amperes (A) for dual-moment transmission. The measurement cycles take approximately 0.5 seconds to complete and are comprised of several hundred individual transients that are averaged into 1D soundings along the profile. This data release includes the averaged, culled, and inverted FloaTEM data along the survey line that were used to produce the final resistivity models. Digital data of the processed soundings are provided, and fields are defined in a data dictionary. (1) Files with *AVERAGED.xyz and *AVERAGED.csv are space- and comma-delimited ASCII files that contain the least processed data where transients were averaged together and most coupled data were removed.Data locations are provided as UTM Zone 15 N projection and datum of WGS-84. (2) Files with *CULLED.xyz and *CULLED.csv are space- and comma- delimited ASCII files containing the processed data where negatively-impacted transients and coupled data were removed using a combination of automated and manual processing. Data locations are provided as UTM Zone 15 N projection and datum of WGS-84. (3) Files with *INVERTED.xyz and *INVERTED.csv are space- and comma-delimited ASCII files containing the inversion model results. Model locations are provided as UTM Zone 15 N projection and datum of WGS-84. (4) Files with *WATER-DEPTH_DATA.xyz and *WATER-DEPTH_DATA.csv are space- and comma-delimited ASCII files containing the water-depth data as measured from the bottom of the transducer. Water-depth measurement locations are provided as UTM Zone 15 N, WGS-84. (5) Files with *INVERTED_image.png and *INVERTED_image.pdf are the inverted model output as a 2D profile of electrical resistivity distribution in the subsurface.

Coastwide Reference Monitoring System (CRMS) 2018 Site 0541 land-water classification data

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring efforts to determine the efficacy of these efforts. The Coastwide Reference Monitoring System (CRMS) was developed to assist in a multiple-reference approach that uses aspects of hydrogeomorphic functional assessments and probabilistic sampling for monitoring. The CRMS program includes a suite of approximately 398 sites that encompass the range of hydrological and ecological conditions for each stratum. As part of CRMS, land and water classifications are created from Digital Orthophoto Quarter Quadrangles (DOQQs) approximately every three years at all CRMS sites. A DOQQ is a raster image in which displacement in the image caused by sensor orientation and terrain relief has been removed and combines the image characteristics of a photo with geometric qualities of a map. The DOQQs generated for this project consist of 2018 Color Infrared (CIR) Digital Imagery. These images were classified into land and water categories using a threshold of the near infrared (NIR) band, followed by supervised and unsupervised classification.  Initial classification results are then reviewed by multiple image analysts to identify and manually recode errors. The final land-water classifications are intended to serve as both geographic and quantitative assessments of landscape composition on the date of acquisition. Four previous assessments have been conducted (2005, 2008, 2012, and 2015/2016). Once the program creates enough data points for statistical analyses, these data will be used for land area change rate calculation.

Caloosahatchee River Nutrient Enrichment Mesocosms: Phytoplankton Taxonomic Quantification September 2019, June 2020, September 2020, February 2021

An interdisciplinary and multiagency study was undertaken to study harmful algal bloom (HAB) dynamics on the Caloosahatchee River, which drains to the west from Lake Okeechobee into the Gulf of Mexico. Algae and cyanobacteria play crucial roles in aquatic ecosystems, but under favorable environmental conditions certain taxa may experience population growth booms resulting in HABs. Four independent mesocosm experiments were conducted in September 2019, June 2020, September 2020, and February 2021 to capture natural temporal variability in water quality and phytoplankton assemblages. The experimental installation consisted of three floating metal cradles each containing four fiberglass chambers filled with native river water. The twelve chambers were assigned to one of four treatments: phosphate (P), nitrate (N), ammonium (A), or control (C) – each with 3 replicates. The P, N, and A treatment chambers were enriched by applying a concentrated dosing solution of either dibasic dodecahydrate sodium phosphate, anhydrous sodium nitrate, or liquid ammonium hydroxide respectively to elevate concentrations above ambient levels. The mesocosms were treated and sampled over a 72-hour period (Time 0, Time 24, Time 48, Time 72). This dataset contains phytoplankton absolute and relative abundance measures at the genus level as natural units (NU/mL), cell densities (cells/mL), and biovolumes (um3/mL).

Previous mineral-resource assessment data compilation - geodatabases with raster mosaic datasets

This zip file contains geodatabases with raster mosaic datasets. The raster mosaic datasets consist of georeferenced tiff images of mineral potential maps, their associated metadata, and descriptive information about the images. These images are duplicates of the images found in the georeferenced tiff images zip file.  There are four geodatabases containing the raster mosaic datasets, one for each of the four SaMiRA report areas: North-Central Montana; North-Central Idaho; Southwestern and South-Central Wyoming and Bear River Watershed; and Nevada Borderlands. The georeferenced images were clipped to the extent of the map and all explanatory text, gathered from map explanations or report text was imported into the raster mosaic dataset database as ‘Footprint’ layer attributes. The data compiled into the 'Footprint' layer tables contains the figure caption from the original map, online linkage to the source report when available, and information on the assessed commodities according to the legal definition of mineral resources—metallic, non-metallic, leasable non-fuel, leasable fuel, geothermal, paleontological, and saleable.
To use the raster mosaic datasets in ArcMap, click on “add data”, double click on the [filename].gdb, and add the item titled [filename]_raster_mosaic. This will add all of the images within the geodatabase as part of the raster mosaic dataset. Once added to ArcMap, the raster mosaic dataset appears as a group of three layers under the mosaic dataset. The first item in the group is the ‘Boundary’, which contains a single polygon representing the extent of all images in the dataset. The second item is the ‘Footprint’, which contains polygons representing the extent of each individual image in the dataset. The ‘Footprint’ layer also contains the attribute table data associated with each of the images. The third item is the ‘Image’ layer and contains the images in the dataset. The images are overlapping and must be selected and locked, or queried in order to be viewed one at a time. Images can be selected from the attribute table, or can be selected using the direct select tool. When using the direct select tool, you will need to deselect the ‘overviews’ after clicking on an image or group of images. To do this, right click on the ‘Footprint’ layer and hover over ‘Selection’, then click ‘Reselect Only Primary Rasters’. To lock a selected image after selecting it, right-click on the ‘Footprint’ layer in the table of contents window and hover over ‘Selection’, then click ‘Lock To Selected Rasters’. Another way to view a single image is to run a definition query on the image. This is done by right clicking on the raster mosaic in the table of contents and opening the layer properties box. Then click on the ‘Definition Query’ tab and create a query for the desired image.

Landscape and contextual field work photos, with locations, taken in September 2023, pre and post Hurricane Lee at Head of the Meadow, Marconi, and Nauset Light beaches in CACO, MA

The data in this release map Marconi Beach, Head of the Meadow Beach, and Nauset Light Beach, in Cape Cod National Seashore (CACO), Massachusetts, before and after Hurricane Lee in September 2023. U.S Geological Survey personnel conducted field surveys to collect topographic data using global navigation satellite systems (GNSS) at all three beaches. In addition, at Nauset Light Beach, an uncrewed aerial system (UAS) was used to collect images with a Ricoh GRII camera for use in structure from motion photogrammetry. High-precision GNSS targets (AeroPoints) were used as ground control points (GCPs) for the UAS photogrammetry. Agisoft Metashape (v. 2.0.1) software was used to create a digital surface model and an orthomosaic from the collected imagery and GCPs. Photos were taken with smartphones for environmental context. This work was conducted under National Park Service Research Permit CACO-2020-SCI-0021.

Characteristics of Dust Associated with the Development of Rapidly Progressive Pneumoconiosis and Progressive Massive Fibrosis

Research and surveillance reports have documented a significant increase in coal workers’ pneumoconiosis, including the most severe forms of progressive massive fibrosis and rapidly progressive pneumoconiosis in U.S. coal miners, particularly those in Appalachian coalfields.  Several possible explanations for these observations include excessive exposures to total respirable dust, increased exposure to freshly fractured silica and silicates, or greater exposure to smaller particles that may be the result of changing mining practices. This dataset contains the chemical and morphological characteristics of particulate matter retrieved from lung tissue slices of historical and contemporary miners.
