This U.S. Geological Survey (USGS) data release contains phytoplankton classification and enumeration results from near-surface samples analyzed by imaging flow cytometry and collected as part of a harmful algae bloom (HAB) monitoring study conducted in collaboration with the New York State Department of Environmental Conservation (NYSDEC). Samples were collected biweekly from monitoring platforms

This data release contains principal facts of gravity measurements collected by the U.S. Geological Survey in 2020-2022, a compilation of existing and new density and magnetic susceptibility data, and gridded magnetic and magnetic potential data of the Bartlett Springs Fault Zone and surrounding areas, northern California. These data support modeling of gravity and magnetic anomalies to characte

The data contain yearly modeled estimates of Pacific salmon escapement (in annual metric tons of wet mass) from 1976 to 2015 across four regions of western North America. A second data file contains modeled estimates of contaminant or nutrient concentrations in Pacific Salmon. The modeled estimates were derived from Bayesian generalized linear models (contaminant or nutrient concentrations) or fro

This dataset includes genotypes and individual-based assignment tests for 868 Atlantic Sturgeon selected for assignment by the National Marine Fisheries Service to meet management requirements under the Endangered Species Act.

In April of 2021, the U.S. Geological Survey conducted a high-resolution seismic survey at Mee Ranch in Monterey County, California. Both passive- and active-source seismic data were acquired using DTCC SmartSolo 3-component nodal seismograph systems ("nodes"), which continuously recorded data at rates up to 2000 samples per second. For passive-source acquisition, a 6x5 grid of nodes was deployed

In June of 2021, the U.S. Geological Survey conducted a high-resolution seismic survey at Winters, California. Seismic data were acquired using a DTCC SmartSolo 3-component nodal seismograph system ("node"), which continuously recorded at 2000 samples per second. Nodes were deployed 5 meters apart from west-southwest to east-northeast to create an approximately 800-m-long linear profile. P-wave da

In May of 2020, the U.S. Geological Survey responded to the M6.5 Monte Cristo Range Earthquake, occurring near Tonopah, Nevada: https://www.usgs.gov/news/featured-story/m65-monte-cristo-range-earthquake. 60 DTCC SmartSolo 3-component nodal seismograph systems ("nodes") were deployed in the area and continuously recorded seismic data for about a month. Nodes were deployed in various arrays includin

This multi-band raster dataset describes the extent of agricultural activity, including both growing and bare or fallow agricultural fields, surrounding the city of Kabul, Afghanistan for 1988 - 2020. Landsat multispectral images acquired at the height of each year's growing season were used to perform a combined vegetation and clay band ratio analysis. Each band of this raster dataset represents

Polygons indicate the extent of urban (gridcode 5) and developed (gridcode 6) land cover in the greater Kabul area. Polygons were created from classification of Landsat 8 Operational Land Imagery (OLI) 30m resolution multispectral satellite imagery acquired on June 13, 2018.

The urbanized area of downtown Menlo Park is subject to persistent flooding and sediment deposition by San Francisquito Creek in South San Francisco Bay. To mitigate these events, a suite of cores was collected in 2002 at the mouth of the creek to determine sediment depositional rates on the delta. One of those cores (721-1) was selected for microbiological (pollen, diatoms, and foraminifera) and

These datasets were created as part of a project to map landslides and other mass movements throughout Sleeping Bear Dunes National Lakeshore. The project aims to address the potential hazards and geomorphic consequences of historic high water levels in Lake Michigan, due to active wave erosion affecting beaches, slopes, and dunes; and coastal inundation. The scale and accuracy of these datasets e

These tabular data were compiled to assess full annual cycle breeding of the Empidonax occidentalis (Cordilleran Flycatcher). Objectives of our study was to assess facets of the full annual cycle of the Cordilleran Flycatcher. These data represent over nine field seasons of work on the Dolores River in southwestern Colorado with field work conducted from 2009-2018. These data were collected from 2
