Southwestern Willow Flycatcher (Empidonax traillii extimus) Surveys and Nest Monitoring in San Diego County, California (ver. 5.0, December 2025)

Data presented are results of surveys and monitoring for Southwestern Willow Flycatcher (Empidonax traillii extimus) in San Diego County, California. These data were collected to assess Southwestern Willow Flycatcher abundance and distribution in San Diego County. Surveys were conducted in various years at 33 locations along 10 drainages in San Diego County, including portions of Agua Hedionda Creek, Cottonwood Creek, Escondido Creek, Los Penasquitos Creek, Otay River, San Diego River, San Dieguito River, San Luis Rey River, Sweetwater River, and Tijuana River. From 2016-19, Southwestern Willow Flycatcher territories were monitored at three locations along the upper San Luis Rey River (Cleveland National Forest, Rey River Ranch, Vista Irrigation District) to determine breeding productivity, survival, and dispersal. Nesting data were compiled to present seasonal productivity for each Southwestern Willow Flycatcher pair. When possible, adults and nestlings in the monitoring area were banded with unique color combinations to identify individuals on subsequent visits to provide data on survivorship and dispersal patterns. From 2024–25 Southwestern Willow Flycatcher territories were monitored at Lake Henshaw to determine breeding productivity and the level of nest parasitism.

High-resolution seismic data acquired near seismic station CE.57213 in Fremont, California

In September 2021, the U.S. Geological Survey acquired high-resolution P- and S-wave data near seismic station CE.57213 in Fremont, California, approximately 100 m east of the mapped trace of the Hayward Fault. We acquired the seismic data to evaluate the time-averaged shear-wave velocity in the upper 30 m (VS30) and to better understand ground-shaking near the station CE.57213. The seismic data were acquired using a linear array of SmartSolo 3-component nodal seismometers (nodes), which continuously recorded at 2000 samples per second (0.5-ms sampling rate). We deployed 60 nodes, spaced at 2-m increments, along a 180-m-long, northeast-southwest-trending linear array. We generated P-wave seismic sources (shots) adjacent to each node at a 1-m offset using a 3.5-kg sledgehammer to vertically strike a steel plate on the ground surface. S-wave sources (shots) were generated adjacent to each node by horizontally striking an aluminum block with a 3.5-kg sledgehammer.  For each shot point, we extracted approximately 2 seconds of data from each node following the shot times, combined the seismic traces into a single shot gather, and stored the data in SEG-Y format (Barry et al, 1975). This report provides the metadata needed to analyze the seismic data.

Fisheries-dependent data for Cisco in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron between 1929 and 1970

This data release presents part of historical fisheries-dependent data for Cisco (Coregonus artedi) in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron collected by scientists from U.S. Geological Survey's Great Lakes Science Center, including three tables for monthly Cisco-catch and fishing-effort data and two tables for biological data of Cisco individuals. The monthly Cisco-catch and fishing-effort data tables are for small-mesh gill-net fisheries in Green Bay and Saginaw Bay (GBSB_GN.csv), pound-net fisheries in Green Bay and Saginaw Bay (GBSB_PD.csv), and shallow trap-net fishery in Saginaw Bay (SB_ST.csv) in the period 1929–1970.&lt;br /&gt;
&lt;br /&gt;
The biological data of Cisco individuals are from historical Saginaw Bay Cisco scale collections of 1942,1945, 1946, 1948, and 1953. These Ciscoes were caught by commercial trap-net fishing carried out by Bay Port Fish Company, located in Bay Port, Michigan. The table “SB_Scale_Collection.csv” includes data associated with the commercial trap-net fishing operations. The table “SB_Scale_Bio.csv” includes biological data (length, weight, sex, maturity) recorded on scale envelopes, and age (i.e., number of annuli on the scale) and back-calculated total length at annulus formation for a subset of these fish samples.&lt;br /&gt;
&lt;br /&gt;

Quantitative polymerase chain reaction (qPCR) cyanotoxin data for 21 sites on Lake Okeechobee and the Okeechobee waterway, Florida, USA collected monthly from March 2019 through October 2021

Quantitative polymerase chain reaction (qPCR) data were compiled for the biosynthesis genes of five toxins of interest produced by cyanobacteria as well as an internal control. Sample deoxyribonucleic acid (DNA) were collected from 21 sites which includes 17 sites from Lake Okeechobee, and four sites from the Caloosahatchee River and the St. Lucie River. Samples were collected on a monthly basis from March 2019 through October 2021, provided water levels were high enough for a sample to be collected. Samples from Lake Okeechobee were collected by the South Florida Water Management District (SFWMD) and samples from the Caloosahatchee and St. Lucie Rivers were collected by the U.S. Geological Survey (USGS). Environmental DNA was extracted soon after collection and samples were analyzed via qPCR throughout the sampling period. Each qPCR assay tests for a different cyanotoxin biosynthesis gene with one assay testing for cyanobacterial 16S DNA as an internal control. The five toxin biosynthesis genes tested were microcystin (mcyE), nodularin (ndaF), saxitoxin (sxtA), anatoxin (anaC), and cylindrospermopsin (cyrA). Results are reported in the number of gene copies per microliter and represent the cyanotoxin biosynthesis gene concentrations in the Lake Okeechobee watershed for the study period.

Geospatial data to assess karst aquifer systems between Albany and Buffalo, New York (ver. 4.0, January 2024)

Using publicly available data for Ontario and Wayne counties, New York, a series of geospatial overlays were created at 1:24,000 scale to examine the bedrock geology, groundwater table, soils, and surficial geology. Bedrock and surficial geology were refined using extant bedrock maps, well and borehole data from water- and gas-wells, soil data, and lidar data. Groundwater data were collected from New York State Department of Environmental Conservation and U.S. Geological Survey water-well databases to estimate the groundwater table. Soil data were used to examine soil thickness over bedrock and infiltration. 
An inventory of closed depressions was created using reconditioned lidar-derived bare-earth digital elevation models (DEMs) and a modeled stream network. Closed depressions were identified from the processed DEMs using threshold criteria of 10 and 30 centimeters (3.9 and 11.8 inches) for depth and 100 square meters (1076 square feet) for area. A combination of hydrologic, mining, and cultural features was used to eliminate false positives and filter out features that overlie existing waterbodies, streams, and mines and to remove artificial dams along roadways and railways. 
This data release includes shapefiles containing the well data information including location, well depth, depth to bedrock, and groundwater depth; bedrock geology; surficial geology; interpolated bedrock surface contours; interpolated groundwater surface contours; soil saturated hydraulic conductivity; soil classes; and modeled closed depressions of 10 cm and 30 cm depth thresholds. This release also contains rasters of the interpolated bedrock surface, interpolated groundwater surface and land use.
