The purpose of the dataset is to replace outdated and inaccurate data, help with the evaluation of sedimentation trends, improve numerical models, inform bathymetry changes near exports, and be a resource for informing management decisions such as dredging. This singlebeam dataset is meant as a supplement to the related multibeam and topographic point datasets from the same date range.</SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>Original field survey datum horizontal: NAD83 (2011) epoch 2017.5, California State Plane Zone III, US Survey Feet; and vertical: NAVD88, US Survey Feet have been converted to California Teale Albers, NAD83 at time of field survey data import.</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>• Survey Dates: Between December 12, 2021 and August 30, 2022. </SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN><SPAN>• Instrumentation: Singlebeam echosounder with Real Time Kinematic (RTK) positioning corrections or direct RTK measurements (see report for locations).</SPAN></SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>• Point Spacing: 3 feet nominal</SPAN></P><P STYLE="margin:0 0 0 0;"><SPAN>For additional details refer to the report "Southern Sacramento-San Joaquin River Delta Condition Bathymetric Survey, October 2022" available upon request.</SPAN></P></DIV></DIV></DIV> |
