This portion of the data release presents sediment grain-size data from samples collected from Anahola Valley, Kaua`i, Hawai`i in November, 2015 (USGS Field Activity 2015-671-FA). 63 sand and mud samples were taken from sediment cores that were collected using a ‘Russian’ corer (a hand-held, side-filling peat auger) from two site locations. Site locations were determined using a hand-held global navigation satellite system (GNSS). The grain-size distributions of samples were determined using standard techniques developed by the USGS Pacific Coastal and Marine Science Center sediment lab. The grain-size data are provided in a comma-delimited spreadsheet (.csv). Core ANA15-RC1 BR contained two carbonate sand layers (Sand A1from 24.5-29 [...]

Data were obtained to analyze vertical grain size trends, and to compare modern and paleo tsunami deposits. These data are intended for science researchers, students, policy makers, and the general public.
