Locations of tree density and monitoring plots during koa moth outbreak, Hawaii Island, 2013-2014

Observers assessed the density and monitored the defoliation, refoliation, and survival of koa (Acacia koa) trees during the 2013-2014 outbreak of  the koa moth (Scotorythra paludicola) at Hakalau Forest National Wildlife Refuge. Koa trees were tagged, classified by size class, and assessed on 55 plots (10-m radius) randomly located in two forest types (reforestation  and natural forest) near Pedro and Pua Akala roads. Density and size class distribution was also assessed for ohia (Metrosideros polymorpha) trees on each plot. This dataset provides the location data for all plots.

Phytoplankton Community Composition in Western Lake Erie, 2014-2018; Grand Traverse Bay, Lake Michigan, 2015; and Saginaw Bay, Lake Huron, 2015

This dataset contains a tabular file of phytoplankton abundance and community composition analysis in samples collected from eight sites in the Western Lake Erie Basin; four sites in Grand Traverse Bay, Lake Michigan; and five sites in Saginaw Bay, Lake Huron. Samples were collected and processed by the Great Lakes Science Center of the U.S. Geological Survey (USGS) and analyzed by BSA Environmental Inc.  Lake Erie sample collection spanned years 2014-2018 with some sites sampled throughout this period and other sites sampled in only some years.  Sample collection in Grand Traverse Bay, Lake Michigan and Saginaw Bay, Lake Huron occurred in 2015. Sample collection was focused in summer and early fall months and data only represent the community present in these seasons.  Site in each basin to represent a gradient of nutrient availability for that basin and are not randomly distributed.  The dataset includes phytoplankton taxa (genus and species), division, tally (number of cells counted for each taxa present), density (cells per liter), and total biovolume (cubic micrometers per liter) for each sample collected. These data can be used to assess the community composition of phytoplankton at the sites, identify cyanobacteria species, and determine abundance and biovolume of any known toxin-producing cyanobacteria. The data were part of a larger study and associated water quality and cyanotoxin data are available through the USGS National Water Information System (NWIS) by searching for site numbers.

Hakalau litter, frass, soil, and understory foliar nitrogen during a koa moth outbreak, 2013-2014

This data release includes metadata and tabular data that document estimates of litterfall, koa moth (Scotorythra paludicola) caterpillar frass production, soil nutrients, and foliar nutrients during 2013-2014 at Hakalau Forest National Wildlife Refuge. During this time, there was a massive defoliation event of Acacia koa (koa) trees by the koa moth. We monitored these metrics in 4 sites that varied in forest structure and composition at Hakalau. We used litter traps to monitor koa litter fall over time and foliar %N to estimate N inputs from litter. We used caterpillar counts, koa canopy estimates, frass production rates, and frass %N to estimate N inputs from frass on the landscape. We used resin bags under koa canopy where frass was directly falling as compared to open grass sites where no frass was falling to monitor soil inorganic N and P over time. Finally we collected foliage of various plant species over time, and tested for %N, under koa versus in the open to track how nutrients in frass fall may track into plants.

Frequency domain electromagnetic induction (FDEM) geophysical data collected near the Agashashok River in the Noatak National Preserve, AK

Frequency domain electromagnetic induction (FDEM) data were collected in September 2016 near the Agashashok River and its tributaries, within the Noatak National Preserve near Kotzebue, AK to aid in local permafrost mapping.  Data were collected with a GEM-2 instrument (1.6 m coil separation, Geophex, Ltd.); a broadband sensor that measures the bulk conductivity and magnetic susceptibility of the subsurface to approximately 5-10 meters depth. The instrument is hand carried by a single operator and data are collected at walking speeds.

Geodetic Centroid (gCent) Catalog

The gCent Catalog is a repository of earthquake centroids and finite fault source information derived from geodetic observations (Shea &amp; Barnhart, 2022). This database additionally includes the fully processed Interferomatric Synethtic Aperture (InSAR) images (unwrapped interferograms) and line-of-sight (LOS) files that were used to derived the cataloged source parameters. Geodetic observations from InSAR provide valuable measurements of ground displacements caused by earthquakes. These spatially-dense (10s of meters per pixel), near-source observations of ground displacement in turn allow for the well-constrained analysis of the spatial characteristics of earthquakes, including their centroid location, depth, dimensions, orientation, and slip magnitude. These source parameters in turn can inform earthquake response products (i.e., ShakeMap, PAGER) and be used to calibrate or compare seismological information (i.e., ComCat). Additionally, the InSAR images ("interferograms") can provide important details about surface ruptures, secondary ground failure (i.e., surface cracking, triggered fault creep, liquefaction, and landslides) that help to guide post-earthquake field surveys. The proliferation of openly available SAR imagery and more reliable image acquisition frequency yield the opportunity to systematically characterize earthquakes with InSAR and incorporate these results into operational earthquake monitoring.

Geophysical and geological data for select petroleum wells in North Coles Levee Oil Field, Kern County, California

This dataset includes geological and geophysical data from petroleum wells located in the North Coles Levee Oil Field, Kern County, California. The purpose of this dataset is to describe groundwater salinity trends and the related geological controls. These data are used in an interpretive manuscript that characterizes a salinity inversion (lower-salinities found below higher-salinities) in North Coles Levee Oil Field. The geophysical data were primarily extracted by selecting data points from scanned well logs; however, some of these logs were digitized in their entirety. The geological data were extracted by interpreting select geologic formations from geophysical well logs relevant to the accompanying manuscript. These datasets were compiled and analyzed as part of the California State Water Resources Control Board Oil and Gas Regional Monitoring Program and the U.S. Geological Survey California Oil, Gas, and Groundwater (COGG) program.

National Land Cover Database (NLCD) 2019 Land Cover Products

The U.S. Geological Survey (USGS), in partnership with several federal agencies, has developed and released five National Land Cover Database (NLCD) products over the past two decades: NLCD 1992, 2001, 2006, 2011, and 2016.  The 2016 release saw landcover created for additional years of 2003, 2008, and 2013. These products provide spatially explicit and reliable information on the Nation’s land cover and land cover change. To continue the legacy of NLCD and further establish a long-term monitoring capability for the Nation’s land resources, the USGS has designed a new generation of NLCD products named NLCD 2019. The NLCD 2019 design aims to provide innovative, consistent, and robust methodologies for production of a multi-temporal land cover and land cover change database from 2001 to 2019 at 2–3-year intervals. Comprehensive research was conducted and resulted in developed strategies for NLCD 2019: continued integration between impervious surface and all landcover products with impervious surface being directly mapped as developed classes in the landcover, a streamlined compositing process for assembling and preprocessing based on Landsat imagery and geospatial ancillary datasets; a multi-source integrated training data development and decision-tree based land cover classifications; a temporally, spectrally, and spatially integrated land cover change analysis strategy; a hierarchical theme-based post-classification and integration protocol for generating land cover and change products; a continuous fields biophysical parameters modeling method; and an automated scripted operational system for the NLCD 2019 production. The performance of the developed strategies and methods were tested in twenty composite referenced areas throughout the conterminous U.S. An overall accuracy assessment from the 2016 publication give a 91% overall landcover accuracy, with the developed classes also showing a 91% accuracy in overall developed.  Results from this study confirm the robustness of this comprehensive and highly automated procedure for NLCD 2019 operational mapping. Questions about the NLCD 2019 land cover product can be directed to the NLCD 2019 land cover mapping team at USGS EROS, Sioux Falls, SD (605) 594-6151 or mrlc@usgs.gov.

Pesticides and pesticide transformation product data from passive samplers deployed in 15 Great Lakes tributaries, 2016

This dataset includes pesticides and pesticide transformation products in 15 tributaries of the Great Lakes. Pesticides were monitored using polar organic chemical integrative samplers (POCIS) to estimate concentrations in water following standard protocols (Alvarez, 2010) in June and July 2016. POCIS extracts were analyzed for 225 chemicals (USGS National Water Quality Laboratory schedule 5437, Sandstrom and others, 2016), for which 129 chemicals also have POCIS uptake rates, allowing calculations of time-weighted mean concentration over the approximately 30 day deployment (Alvarez and others, 2008). Collectively, there were 97 chemicals detected, and time-weighted mean concentrations could be calculated for 95 chemicals. The data support the findings in the associated journal article (https://doi.org/TBD).

Velocity mapping in the tailwater of Kentucky Dam (Tennessee River) near Gilbertsville, Kentucky, September 12 and 17–18, 2020

Water velocities were measured at discrete cross-sections along an approximately 1-mile reach of the Kentucky Dam tailwater on September 12 and 17-18, 2020, using a 1200 kHz acoustic Doppler current profiler (ADCP). The data were geo-referenced with an integrated global navigation satellite system (GNSS) smart antenna with submeter accuracy. The ADCP and GNSS antenna were mounted on a marine survey vessel, and data were collected as the survey vessel traversed the tailwater along planned survey lines. There was typically one reciprocal pair (two passes) of data collected per line. There was a total of 53 survey lines equally spaced 100 feet apart and oriented approximately perpendicular to the primary flow direction. Data collection software integrated and stored the velocity and position data from the ADCP and GNSS antenna in real time. Data were processed using the Velocity Mapping Toolbox (Parsons and others, 2013) to derive temporally- and spatially-averaged water velocity values. These velocity measurements were collected during three different steady discharge conditions from the hydropower turbines at Kentucky Dam. The average rated discharges on September 12, 17, and 18 were 8,300 cubic feet per second (cfs), 59,000 cfs, and 28,000 cfs, respectively. These data were collected to understand flow patterns in the Kentucky Dam tailwater during different discharge conditions from the hydropower turbines at Kentucky Dam and may be used to assist in invasive carp capture and control programs.

Bathymetry in the tailwater of Kentucky Dam (Tennessee River) near Gilbertsville, Kentucky, September 17–18, 2020

These data are bathymetry (river bottom elevation) in XYZ format (Easting, Northing, Elevation), generated from the September 17–18, 2020, survey of the Kentucky Dam tailwater from just downstream from Kentucky Dam to approximately 1,500 feet upstream from the I-24 bridge (about 1 mile total length). Bathymetric data were collected using an acoustic Doppler current profiler (ADCP) with an integrated global navigation satellite system (GNSS) smart antenna. The ADCP and GNSS antenna were mounted on a marine survey vessel, and data were collected as the survey vessel traversed the tailwater along planned survey lines. There was typically one reciprocal pair (two passes) of data collected per line. There was a total of 53 survey lines equally spaced 100 feet apart and oriented approximately perpendicular to the primary flow direction. Data collection software integrated and stored the depth and position data from the ADCP and GNSS antenna in real time. Water-surface elevations were measured at each planned line throughout the survey area with a survey-grade integrated GNSS system with real-time kinematic (RTK) observations in order to convert measured bathymetric depths to elevations referenced to NAVD 88. RTK observations were made using the Kentucky Continually Operating Reference System (KYCORS) network operated by the Kentucky Transportation Cabinet. Data processing required computer software to extract the bathymetric data from the raw data files and to summarize and map the information.
