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.

Hawaii Volcanoes National Park Forest Composition and Hawaii Elepaio Breeding Behavior 1992-1994 and 2015-2019 Hawaii Volcanoes National Park Forest Composition and Hawaii Elepaio Breeding Behavior 1992-1994 and 2015-2019
This data release contains the tabular data and metadata to record changes in forest composition (tree species relative abundance, tree density, tree height, and tree diameter) over a span from 1993-1994 and 2015-2019. The data also includes Hawaii elepaio breeding territory sizes, and nest site selection (nest tree species, nest tree height, nest tree diameter).
Results of repeated leveling surveys near the Three Sisters volcanic center, central Oregon, 2002-2008 Results of repeated leveling surveys near the Three Sisters volcanic center, central Oregon, 2002-2008
This Data Release includes results of repeated leveling surveys each summer from 2002 to 2006 and in 2008 along two short traverses in the Three Sisters Wilderness Area, central Oregon Cascade Range. A data dictionary explains the file format and contents. The dataset will be updated if new measurements are collected, which is unlikely unless there is a significant change in the rate or...
Data on Blood Analytes and Post-Release Survival in Spectacled Eiders (Somateria fischeri), Northern Alaska, 2010-2011 Data on Blood Analytes and Post-Release Survival in Spectacled Eiders (Somateria fischeri), Northern Alaska, 2010-2011
These data are in one table of variables that potentially influenced the immediate post-release survival of spectacled eiders (Somateria fischeri) from the Colville River Delta, Alaska marked with coelomically implanted satellite transmitters with percutaneous antennae in 2010 and 2011.
Phytoplankton data for Cheney Reservoir near Cheney, Kansas, June 2001 through September 2020 (ver. 3.0, August 2021) Phytoplankton data for Cheney Reservoir near Cheney, Kansas, June 2001 through September 2020 (ver. 3.0, August 2021)
This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from Cheney Reservoir, Kansas, during June 2001 through September 2020. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS...
Composite multibeam bathymetry surface and data sources of the southern Cascadia Margin offshore Oregon and northern California (version 2.0, April 2026) Composite multibeam bathymetry surface and data sources of the southern Cascadia Margin offshore Oregon and northern California (version 2.0, April 2026)
Bathymetry data from various sources, including USGS-funded multibeam data collected between 2018-2022 by the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS), were combined to create a composite 30-m resolution multibeam bathymetry surface of the southern Cascadia Margin offshore of Oregon and northern California. The bathymetry data are...
Donated AUV bathymetry and Chirp seismic-reflection data collected during Monterey Bay Aquarium Research Institute cruises in 2018-2019 offshore of south-central California Donated AUV bathymetry and Chirp seismic-reflection data collected during Monterey Bay Aquarium Research Institute cruises in 2018-2019 offshore of south-central California
This data release consists of donated AUV bathymetry and Chirp seismic-reflection data collected using an autonomous underwater vehicle (AUV) in 2018 and 2019. The collection of these data was funded entirely by the Monterey Bay Aquarium Research Institute (MBARI), and the data have been donated to the U.S. Geological Survey (USGS). The data were collected in collaboration with the USGS...
