Bathymetry was measured with a single-beam echo-sounder (10 Hz 144 ODOM Echotrac CV-100) mounted on the stern of a small vessel and synchronized to a 145 Real-Time Kinematic (RTK) Global Positioning Systems (GPS). The depth is measured relative to approximate Mean Sea Level (see attribute accuracy report in this file for further details on the MSL), and depth values are meters below the water surface. The GPS sampling rate was 1 Hz with vehicle speeds maintained at less than 15 km/hour, resulting in a sample point resolution of 3-5 meters. Data are available in a single csv file. 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.

Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: There is no established vertical geodetic, nor tidal datum for much of Arctic Alaska, including where this study took place. A mean sea level elevation was estimated using data measured with the NortekTM pressure sensor (see 2009TimeSeriesData_WaterDepths*) and is considered a proxy for a local mean sea level datum in the study area. Reported bathymetry is relative to that datum. No formal accuracy assessment was performed. Logical_Consistency_Report: All data fall within expected ranges. 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 data set has not been conducted. The horizontal positioning errors are estimated to be plus/minus 0.1 m, based on system configuration, sea state (waves, local tides), vessel speed and the assumed speed of sound in water (1500 m/s). Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: A formal accuracy assessment of the vertical positional information in the data set has not been conducted. The vertical positioning errors are estimated to be plus/minus 0.15 m, based on system configuration, sea state (local tides, waves), vessel speed and the assumed speed of sound in water (1500 m/s).
