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.

(ORB II-13 (100)) Geologic map of the Maestlin G region of the moon, Lunar Orbiter site II P-13, Oceanus Procellarum, including Apollo landing site 5 (ORB II-13 (100)) Geologic map of the Maestlin G region of the moon, Lunar Orbiter site II P-13, Oceanus Procellarum, including Apollo landing site 5
This map shows the geology in and around potential early Apollo landing site 5 in the lunar equatorial belt. The Maestlin G region is in Oceanus Procellarum, about midway between the crater Kepler to the northeast and Flamsteed to the southwest. Terra materials occur only in the northeast corner of the region. Dark mare covers the remainder, and the entire region is crossed by rays from...
Geologic map of the Maskelyne DA region of the moon, Lunar Orbiter site II P-2, southeastern Mare Tranquillitatis including Apollo landing site l Geologic map of the Maskelyne DA region of the moon, Lunar Orbiter site II P-2, southeastern Mare Tranquillitatis including Apollo landing site l
This map shows the geology in and around potential early Apollo landing site 1 in the lunar equatorial belt. The Maskelyne DA region, at the southeastern edge of the Mare Tranquillitatis, is in the area transitional between mare and terra. Patches of typical terra material occur on northwest-trending ridges, and typical heavily cratered mare materials occurs only in the east-central part...
A comparison of pan trap and hand net bee collection methods at Badlands National Park, South Dakota, 2012 A comparison of pan trap and hand net bee collection methods at Badlands National Park, South Dakota, 2012
This data record includes bee species captured by pan trap or hand net in 1-hectare, mixed-grass prairie plots at Badlands National Park, South Dakota, in 2012.
Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity L-4-90-SC Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity L-4-90-SC
Multichannel seismic (MCS) data were collected by the U.S. Geological Survey (USGS) in 1990 in the California Continental Borderland (USGS field activity L490SC). In 2021, these data were reprocessed to improve accuracy and resolvability of geologic structures and fault systems of California's continental margin. MCS data were acquired to support the Southern California Earthquake...
Multichannel sparker and chirp seismic reflection data collected during USGS field activity 2018-658-FA between Cape Blanco and Cape Mendocino in October of 2018 Multichannel sparker and chirp seismic reflection data collected during USGS field activity 2018-658-FA between Cape Blanco and Cape Mendocino in October of 2018
This data release contains processed high-resolution multichannel sparker seismic-reflection (MCS) data and chirp sub-bottom data that were collected aboard Humboldt State University's R/V Coral Sea in October of 2018 on U.S. Geological Survey cruise 2018-658-FA on the shelf and slope between Cape Blanco, Oregon, and Cape Mendocino, California. MCS data were collected to characterize...
U.S. Geological Survey simulations of 3D-hydrodynamics in Delaware Bay (2016, 2018, 2021) to improve understanding of the mechanisms driving salinity intrusion U.S. Geological Survey simulations of 3D-hydrodynamics in Delaware Bay (2016, 2018, 2021) to improve understanding of the mechanisms driving salinity intrusion
The Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST Warner and others, 2019; Warner and others, 2010) model was used to simulate three-dimensional hydrodynamics and waves to study salinity intrusion in the Delaware Bay estuary for 2016, 2018, 2021. Salinity intrusion in coastal systems is due in part to extreme events like drought or low-pressure storms and longer-term sea level...
