In accordance with SO #3423 - The Gulf of America and SO #3424 - Mount McKinley and Landmarks Honoring the Alaskan People, new USGS data releases specific to those named places will utilize the new name Gulf of America and the restored name Mount McKinley. Per USGS practice, historical data will retain the name of the geographic features as they were known at the time the data were originally released.

Archive of Chirp Subbottom Profile Data Collected in 2023 From Oahu, Hawaii

Summary
As part of the Coastal Sediment Availability and Flux and Defense Advanced Research Protection Agency (DARPA) Reefense projects, scientists from the U.S. Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a nearshore geophysical survey to map the shoreface and inner shelf, as well as characterizing stratigraphy near Oahu, Hawaii (HI) in May 2023. The purpose of this study was to conduct a geologic assessment (including bathymetric mapping) near Fort Hase Beach, Oahu, in support of efforts to construct an artificial coral reef offshore of Ft. Hase Marine Corps Base Hawaii. Collecting geophysical data can help researchers to identify relationships between the geologic history of the island, its present-day morphology, and sediment distribution.
This data release serves as an archive of subbottom profile and navigation data collected May 7–13, 2023, offshore of Kailua, HI, during USGS Field Activity Number 2023-310-FA. Data products, including chirp subbottom profile data and images, survey trackline maps, location data with formal Federal Geographic Data Committee (FGDC) metadata, and field logs are provided. Coastal bathymetry and imagery data were also collected during this geophysical survey and are provided in another data release.
