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.

Dataset of diatom controls on the compressibility and permeability of fine-grained sediment collected offshore of South Korea during the Second Ulleung Basin Gas Hydrate Expedition, UBGH2 Dataset of diatom controls on the compressibility and permeability of fine-grained sediment collected offshore of South Korea during the Second Ulleung Basin Gas Hydrate Expedition, UBGH2
One of the primary goals of South Korea's second Ulleung Basin Gas Hydrate Expedition (UBGH2) was to examine the geotechnical properties of the marine sediment associated with methane gas hydrate occurrences found off the shore of eastern Korea in the Ulleung Basin, East Sea. Methane gas hydrate is a naturally occurring crystalline solid that sequesters methane in individual molecular...
Dataset of diatom controls on the sedimentation behavior of fine-grained sediment collected offshore of South Korea during the Second Ulleung Basin Gas Hydrate Expedition, UBGH2 Dataset of diatom controls on the sedimentation behavior of fine-grained sediment collected offshore of South Korea during the Second Ulleung Basin Gas Hydrate Expedition, UBGH2
One of the primary goals of South Korea's second Ulleung Basin Gas Hydrate Expedition (UBGH2) was to examine the geotechnical properties of the marine sediment associated with methane gas hydrate occurrences found offshore of eastern Korea in the Ulleung Basin, East Sea. Methane gas hydrate is a naturally occurring crystalline solid that sequesters methane in individual molecular cages...

The abundance of wildlife occurrence datasets that are currently accessible can be valuable for efforts such as species distribution modeling and range delineation. However, the task of downloading and filtering occurrence records is often complex due to errors and uncertainties that are present in datasets. This repository provides a high-level framework for acquiring and filtering...
Topobathymetric Model of the Coastal Georgia, 1851 to 2020 Topobathymetric Model of the Coastal Georgia, 1851 to 2020
To support Hurricane Florence impact modeling of storm-induced flooding and sediment transport, the U.S. Geological Survey (USGS) Coastal National Elevation Database (CoNED) Applications Project has created an integrated 1-meter topobathymetric digital elevation model (TBDEM) for coastal Georgia. High-resolution coastal topobathymetric data are required to characterize flooding, storms...
Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2022 (ver 6.0, July 2022) Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2022 (ver 6.0, July 2022)
These datasets provide early estimates of 2022 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a bi-weekly basis from May to early July. The EAG estimates are developed within one week of the latest satellite observation used for that version. Each bi-weekly release contains four fractional cover maps along with their corresponding...
Data Release for Secondary Hydrogeologic Regions of the Conterminous United States (ver. 2.0, June 2022) Data Release for Secondary Hydrogeologic Regions of the Conterminous United States (ver. 2.0, June 2022)
The U.S. Geological Survey (USGS) previously identified 62 Principal Aquifers (PAs) in the U.S., with 57 located in the conterminous states. The USGS characterized areas outside of PAs as “other rocks;” other rocks account for about 40% of the area of the conterminous states. This paper subdivides the large area identified as other rocks into Secondary Hydrogeologic Regions (SHRs). SHRs...
