| Radiocarbon data from coastal wetlands on the Hawaiian islands of Kaua'i, O'ahu, and Hawai'i | Push corer | This portion of the data release presents radiocarbon age data from 66 samples collected from Anahola Valley (Kaua'i), Kahana Valley (O'ahu), and Pololu Valley (Hawai'i). Sample ages were determined by the National Ocean Sciences Accelerator Mass Spectrometry (NOSAMS) facility. The data are provided in a comma-delimited spreadsheet (.csv). | SeanPaul M La Selle |
| Core descriptions and sand bed thickness data from Kahana Valley, O'ahu, Hawai'i | Push corer | This portion of the data release contains information on cores that were collected by the U.S. Geological Survey in Kahana Valley, O'ahu, Hawaii in 2015 and 2017. Sites were cored in order to describe wetland stratigraphy and to identify potential tsunami deposits. These cores contain mud, peat, fluvial sands, and marine carbonate sands, reflecting deposition in a variety of coastal environments. PDF files describe twenty-four (24) gouge and 'Russian' cores (hand held, side-filling peat augers) that were collected and described in the field. Cores collected in 2017 were described using the Troels-Smith sediment classification scheme (Troels-Smith, 1955, Nelson, 2015). Another pdf file (Kahana_cores_legend.pdf) contains a core-log legend. A comma-delimited text file (Kahana_sand_thickness.csv) includes tabulated information on the depth and thickness of sand bed K1. In addition, a shapefile (kahana_cores_locations.shp) provides sample locations of the vibracores. | SeanPaul M La Selle |
