Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Digital elevation model of K?lauea Volcano, Hawaii, based on July 2019 airborne lidar surveys Digital elevation model of K?lauea Volcano, Hawaii, based on July 2019 airborne lidar surveys
The 2018 eruption of Kilauea Volcano on the Island of Hawaii saw the collapse of a new, nested caldera at the volcano?s summit, and the inundation of 35.5 square kilometers (13.7 square miles) of the lower Puna District with lava. Between May and August, while the summit caldera collapsed, a lava channel extended 11 kilometers (7 miles) from fissure 8 in Leilani Estates to Kapoho Bay...
Image data and field measurements used to map salmon spawning locations via remote sensing, American River, California, November 5-7, 2018 Image data and field measurements used to map salmon spawning locations via remote sensing, American River, California, November 5-7, 2018
This data release includes images and field measurements used to map chinook salmon spawning locations along the American River near Sacramento, California, via remote sensing; the data were collected November 5-7, 2018. The purpose of this study was to develop and test a spectrally based technique for identifying salmon spawning locations, known as redds, from various types of remotely...
Beach topography and near-shore bathymetry of Lake Superior at Minnesota Point, Duluth, MN, August 2019 Beach topography and near-shore bathymetry of Lake Superior at Minnesota Point, Duluth, MN, August 2019
This dataset is a digital elevation model (DEM) of the beach topography and near-shore bathymetry of Lake Superior at Minnesota Point, Duluth, Minnesota. The DEM has a 10-meter (m; 32.8084 feet) cell size and was created from a LAS (industry-standard binary format for storing large point clouds) dataset of terrestrial light detection and ranging (LiDAR) data representing the beach...
Meteorological Database, Argonne National Laboratory, Illinois, January 1, 1948 - September 30, 2019 Meteorological Database, Argonne National Laboratory, Illinois, January 1, 1948 - September 30, 2019
This data release is the update of the U.S. Geological Survey - ScienceBase data release by Bera (2019), with the processed data through September 30, 2019. The primary data for water year 2019 (a water year is the 12-month period, October 1 through September 30, in which it ends) is downloaded from the Argonne National Laboratory (ANL) (Argonne National Laboratory, 2019) and is...
Abundance of 50 transcripts from microdissected liver samples of smallmouth bass Abundance of 50 transcripts from microdissected liver samples of smallmouth bass
There is an increasing emphasis on effects-based monitoring to document responses associated with exposure to complex mixtures of chemicals, climate change, pathogens, parasites and other environmental stressors in fish populations. For decades aquatic monitoring programs have included the collection of tissues preserved for microscopic pathology. Consequently, formalin-fixed, paraffin...
Benthic Foraminiferal Data from Surface Samples and Sedimentary Cores in the Grand Bay Estuary, Mississippi and Alabama Benthic Foraminiferal Data from Surface Samples and Sedimentary Cores in the Grand Bay Estuary, Mississippi and Alabama
Microfossil (benthic foraminifera) samples were obtained from surficial grab (denoted with 'G') and push core (denoted with 'M') sediments collected in Grand Bay estuary, Mississippi and Alabama, to aid in the paleoenvironmental understanding of Grand Bay estuary. The data presented here were collected as part of the U.S. Geological Survey's Sea-level and Storm Impacts on Estuarine...
