    "descript": "Underwater images totaling 78,924 in number were collected offshore Fort Hase, Marine Corps Base Hawaii (MCBH) and Coconut Island, Oahu, Hawaii, during May 2023, using the Polecam system developed by the U.S. Geological Survey (USGS). The Polecam system is a single downward-looking underwater Teledyne FLIR camera with a Computar V1228-MPY lens and with a rigidly-attached Global Navigation Satellite System (GNSS) antenna mounted above and forward of the camera's central axis. The Polecam system captured images as Tag Image File Format (TIFF, .tif) files to maintain the highest resolution and bit depth. In this data release, the files were converted into Joint Photographic Experts Group (JPEG, .jpg) files to enhance the accessibility of the imagery. Each image contains imagery header metadata embedded within the file, including GNSS date, time, latitude and longitude of the GNSS antenna, copyright, keywords, and other descriptive information. Refer to the \u2018IMAGERY HEADERS\u2019 Process Step of the metadata for more information on the imagery headers. Chirp subbottom profile data were also collected during this same survey (2023-310-FA), please refer to Forde and others (2024) for more information.",
