Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2022, May 6th, 2022 (revised on May 17th, 2022)

These datasets provide early estimates of 2022 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a bi-weekly basis from May to early July. The EAG estimates are developed within one week of the latest satellite observation used for that version. Each bi-weekly release contains four fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) cheatgrass (Bromus tectorum); 3) medusahead (Taeniatherum caput-medusae); and 4) Sandberg bluegrass (Poa secunda). These datasets were generated leveraging field observations from Bureau of Land Management (BLM) Assessment, Inventory, and Monitoring (AIM) data plots; Harmonized Landsat and Sentinel-2 (HLS) based Normalized Difference Vegetation Index (NDVI); HLS-based Normalized Difference Water Index (NDWI); other relevant environmental, vegetation, remotely sensed, and geophysical drivers; and artificial intelligence/machine learning techniques. A total of 19,415 AIM plots from years 2016 – 2021 were used to train an ensemble of five-fold regression-tree models using a cross-validation approach (each observation was used as test data once) that developed all the fractional cover maps. The geographic coverage includes arid and semi-arid rangelands in the western U.S at or below 2350-m elevation.
Note: Maps of May 6th, 2022 were developed using satellite observation data no later than April 29.
Maps of May 18th, 2022 were developed using satellite observation data no later than May 13.

Sea Turtle Nesting Decision Points and Cross-Shore Beach Profile Data Collected on May 20, 2021, from Juno Beach, Florida

On May 20, 2021, surveys were conducted on ‘high-density’ sea turtle nesting areas located on Juno Beach, Florida. This dataset, Juno_20210520.zip, was collected and processed by the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) and includes sea turtle nesting decision point locations (.csv) and cross-shore beach profiles (.xyz) at those locations. Utilizing previously published methods for collecting beach profile data (Henderson and others, 2016; Brown and others, 2018), data were acquired by USGS scientists walking along cross-shore transect lines while carrying a survey backpack that was equipped with a Global Navigation Satellite System (GNSS) receiver and GNSS antenna. The horizontal position data are provided in the Universal Transverse Mercator (UTM) coordinate system, Zone 17 North (17N), referenced to the North American Datum of 1983 (NAD83), and the elevation data are referenced to the North American Vertical Datum of 1988 (NAVD88), GEOID12B.

West Africa Land Use Land Cover Time Series

This series of three-period land use land cover (LULC) datasets (1975, 2000, and 2013) aids in monitoring change in West Africa’s land resources (exception is Tchad at 4 kilometers). To monitor and map these changes, a 26 general LULC class system was used. The classification system that was developed was primarily inspired by the “Yangambi Classification” (Trochain, 1957). This fairly broad class system for LULC was used because the classes can be readily identified on Landsat satellite imagery. A visual photo-interpretation approach was used to identify and map the LULC classes represented on Landsat images. The Rapid Land Cover Mapper (RLCM) was used to facilitate the photo-interpretation using Esri’s ArcGIS Desktop ArcMap software.

Coastwide Reference Monitoring System (CRMS) 2005, 2008, 2012, 2016 and 2018 Site 0303 land-water matrix

Wetland restoration efforts conducted by the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in Louisiana rely on monitoring to determine the efficacy of these projects. 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 390 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. This dataset consists of a matrix of five land-water products (2005, 2008, 2012, YYYY and 2018).  The resulting matrix has 32 possible classes defined by the combination of land and water categories on those five dates.

Autonomous Flow-Thru (AFT) CO2 data of the West Florida Shelf: USGS Cruise 11BHM02

The United States Geological Survey (USGS) is conducting a study on the effects of climate change on ocean acidification within the Gulf of Mexico; dealing specifically with the effect of ocean acidification on marine organisms and habitats. To investigate this, the USGS participated in cruises in the West Florida Shelf and northern Gulf of Mexico regions aboard the R/V Weatherbird II, a ship of opportunity lead by Dr. Kendra Daly, of the University of South Florida (USF). This cruise occurred June 25 - 30, 2011, leaving from and returned to Saint Petersburg, Florida. The USGS collected data pertaining to pH, dissolved inorganic carbon (DIC), and total alkalinity in discrete samples over a span of 1632 kilometer (km) track line, additionally 36 discrete samples were taken at ten stations, these were taken at various depths. Flow-through conductivity-temperature-depth (CTD) data were collected, which includes temperature, salinity, and pH. Corroborating the USGS data are the vertical CTD profiles collected by USF, using the following sensors: CTD, oxygen, chlorophyll fluorescence, optical backscatter, and transmissometer. Additionally, discrete depth samples for nutrients, chlorophyll, and particulate organic carbon/nitrogen were collected.

MODFLOW-NWT and MODPATH groundwater flow models of the Farmington River Watershed (Connecticut and Massachusetts)

Groundwater flow models have the potential to predict spatial groundwater discharge 
dynamics within river networks, but models are often not evaluated against discharge 
dynamics.  The objective of this study was to understand the variation in simulated 
discharge dynamics (discharge location, flowpath depth, and subsurface travel time) 
for models with common, but varying frameworks and assumptions. The University of 
Connecticut in collaboration with the United States Geological Survey developed a 
groundwater flow model (MODFLOW-NWT) for the Farmington River Watershed  
(1,570 km2)  in the northeastern United States and systematically varied the type 
of typical calibration data (well head and stream elevation); calibration parameters; 
parameters related to permeability of the surficial materials, bedrock, and riverbed 
sediments; control of river-aquifer exchange directionality; and model resolution. 
Each model variation has an associated particle tracking (MODPATH) model. 
Subsequent work, not described in this model archive, compared with simulated 
spatial patterns of groundwater discharge with patterns observed with hand-held 
thermal infrared imagery. This dataset contains model inputs and outputs, 
post-processing python scripts, and pest calibration input files for 12 model 
variations described in the associated journal article 
(https://doi.org/10.1029/2020WR028027)

Ground conductivity measurements at selected National Wildlife Refuges: Rabenberg, Montana, 2017

Shallow subsurface electrical conductivity was mapped at Rabenberg National Wildlife Refuge (NWR) in northeast Montana using the DUALEM421 electromagnetic sensor (Dualem, Inc., ON, Canada) in the winter of 2017. Data were acquired by towing the DUALEM421 sensor on a sled behind an all-terrain vehicle or snow machine, with the sensor at a nominal height of 0.3 meters (m) above ground surface. Approximately 32 line-kilometers (km) of data were acquired over an area of approximately 1 square-kilometer. Data were manually edited to remove sensor dropouts, lag corrected for apparent offsets between recorded GPS location and data locations for each coil pair, and averaged to a sounding distance of 1m along the survey path; data were not decoupled from infrastructure noise sources (powerlines, pipelines, fences, etc.) or corrected for sensor pitch or roll. This data release contains raw and processed electromagnetic data. Digital data are described by the data dictionaries. Additional details regarding the processing steps are described in the metadata.

Coastal Land-Cover Data Derived from Landsat Satellite Imagery, Northern Chandeleur Islands, Louisiana, 1984-2019

The data release (Bernier, 2021) associated with this metadata record serves as an archive of coastal land-cover and feature datasets derived from Landsat satellite imagery at the northern Chandeleur Islands, Louisiana. To minimize the effects of tidal water-level variations, 75 cloud-free, low-water images acquired between 1984 and 2019 were analyzed. Water, bare earth (sand), vegetated, and intertidal land-cover classes were mapped from Hewes Point to Palos Island using successive thresholding and masking of the modified normalized difference water index (mNDWI), the normalized difference bare land index (NBLI), and the normalized difference vegetation index (NDVI). Vector shoreline, sand, and vegetated feature extents were extracted for each image by contouring the spectral indices using the calculated threshold values. The geographic information system (GIS) data files with accompanying formal Federal Geographic Data Committee (FGDC) metadata can be downloaded from https://doi.org/10.5066/P9HY3HOR.

Topographic and bathymetric data on the mainstem Nooksack River, Fall 2015

Bathymetric and topographic data on the mainstem Nooksack River, Whatcom County, Washington were collected in the fall of 2015 as part of a study on sediment transport and channel change. Bathymetric data was collected from the river's mouth to river mile (RM) 28, near Nugent's Corner. Topographic data is available from RM 17, near the town of Lynden, to RM 37, near the confluence of the Middle Fork Nooksack. More information on these datasets is available in their respective metadata. The overlapping extents of these surveys were merged to create a seamless elevation data set of the river bed and active channel. Aerial lidar acquired in 2013 was used to fill in holes where vegetation prevented photogrammetric reconstructions and to provide elevation data for the floodplain.
