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.

At-site flood frequency estimates for 154 urban streamgages in Washington D.C. and parts of Delaware, Maryland, New Jersey, Pennsylvania, and Virginia using data through water year 2022 At-site flood frequency estimates for 154 urban streamgages in Washington D.C. and parts of Delaware, Maryland, New Jersey, Pennsylvania, and Virginia using data through water year 2022
This dataset contains site information and results of flood frequency analysis for 154 urban streamflow gaging stations (streamgages) operated by the U.S. Geological Survey (USGS) in Washington D.C. and parts of Delaware, Maryland, New Jersey, Pennsylvania, and Virginia. Site information and annual peak-flow data from the 1924 - 2022 water years were obtained from the USGS National Water

Multi-proxy geochemical and sedimentological data from 20 short sediment cores collected along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the lower Mesopotamian Plain, Iraq Multi-proxy geochemical and sedimentological data from 20 short sediment cores collected along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the lower Mesopotamian Plain, Iraq
This data release presents multi-proxy geochemical and sedimentological data from 20 short sediment cores (ranging 50–70 cm in depth) collected in 2003 along the Euphrates, Tigris, and Shatt al-Gharraf rivers in the Lower Mesopotamian Plain, Iraq. The dataset includes X-ray fluorescence (XRF) elemental abundances, particle size distributions, visible and near-infrared spectrophotometry...
National Shoreline Change—A GIS compilation of vector shorelines and associated shoreline change data from the 1800s to the 2010s for the coast of Long Island Sound, New York and Connecticut National Shoreline Change—A GIS compilation of vector shorelines and associated shoreline change data from the 1800s to the 2010s for the coast of Long Island Sound, New York and Connecticut
The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from various historical sources, such as aerial photographs or topographic surveys, and contemporary sources, such as lidar-point clouds and digital elevation models. Shorelines are compiled in a GIS and analyzed in the USGS Digital Shoreline Analysis System (DSAS) software to calculate rates of...
Physical volcanology data and measurements (grain size, grain shape, thickness, maximum clast size, ballistic block size, and componentry) from the May 11–27, 1924 tephra deposits of Halemaʻumaʻu crater, Kīlauea volcano, Island of Hawaiʻi Physical volcanology data and measurements (grain size, grain shape, thickness, maximum clast size, ballistic block size, and componentry) from the May 11–27, 1924 tephra deposits of Halemaʻumaʻu crater, Kīlauea volcano, Island of Hawaiʻi
Over 16 days from May 11–27, 1924, there were more than 50 explosions from Halemaʻumaʻu crater at Kīlauea volcano on the Island of Hawaiʻi. These explosions ejected blocks weighing >12,000 kg, as well as extremely fine ash to lapilli size tephra. The greatest thicknesses of tephra were at the summit region of Kīlauea, but some tephra fell on Wood Valley, Pāhala, and Waiʻōhinu to the...
Delineated watersheds and snapped locations for select streamgages in and near Wyoming Delineated watersheds and snapped locations for select streamgages in and near Wyoming
The U.S. Geological Survey (USGS), in cooperation with the Wyoming Water Development Office, delineated watersheds for 800 active and discontinued USGS streamgages in and near Wyoming. This data release includes shapefiles of streamgage location points and polygons of their delineated watersheds. Streamgage locations were snapped to the USGS High Resolution National Hydrography Dataset...
