The instrument was mounted on the frame approximately 0.50 m off the bottom of the seafloor. Salinity was calculated from conductivity measurements. Purpose: Data were obtained to provide baseline information and to support the development of numerical models for assessing past and future coastal hazards. These data are intended for policy makers, resource managers, science researchers, students, and the general public. These data are not intended to be used for navigation. Supplemental_Information: Additional information about the field activities from which these data were derived is available online at: https://cmgds.marine.usgs.gov/fan_info.php?fan=TM109AR https://cmgds.marine.usgs.gov/fan_info.php?fan=TM209AR Any use of trade, product, or firm names is for descriptive purposes only and does not imply endorsement by the U.S. Government.

Online_Linkage: https://www.jodc.go.jp/info/ioc_doc/UNESCO_tech/047363eb.pdf Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: Conductivity was calibrated by holding the sensor in bottles with solutions of known salinity concentrations and values adjusted on the instrument accordingly. No calibration or formal accuracy tests were performed on the temperature and pressure sensors. Logical_Consistency_Report: All data fall within expected ranges. Missing data have been filled with -9999 values. Completeness_Report: Dataset is considered complete for the information presented, as described in the abstract. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: A formal accuracy assessment of the horizontal positional information in the dataset has not been conducted. Marine point locations were measured with a hand-held, WAAS enabled Garmin 76CSx GPS unit. Horizontal accuracy is estimated to be 5 meters. Lineage: Process_Step: Process_Description: Time series of conductivity and temperature were collected at approximately 10 m water depth using a Seabird SBE37 microcat, sampling every 2 minutes. Post-survey calculations of salinity were computed from the conductivity measurements using methods of PSS78 UNESCO, 1981.
