Revision History for U.S. Geological Survey Open-File Report 2011-1315 By Amy C. Foxgrover, David P. Finlayson, Bruce E. Jaffe, and Theresa A. Fregoso Bathymetry and Digital Elevation Models of Coyote Creek and Alviso Slough, South San Francisco Bay, California --------------------------------------------------------- Posted online January 5, 2012 -------------------------------------------------------- Revised and reposted July 31, 2013 Title changed from: “2010 Bathymetry and Digital Elevation Model of Coyote Creek and Alviso Slough, South San Francisco Bay, California” to: “Bathymetry and Digital Elevation Models of Coyote Creek and Alviso Slough, South San Francisco Bay, California.” Added Theresa Fregoso as a co-author. Expanded disclaimer section on back of title page in accordance with Bureau Approving Officials guidelines. Modified abstract to incorporate four additional bathymetry surveys. Added table 1 with individual cruise IDs and dates. Updated figure 1 close-up to show individual extents on the 3 cruises that comprise the 2010 survey. Added figure 7 as an example of change between bathymetric surveys. Added last two paragraphs under the section “Estimates of Bathymetric Uncertainty” to elaborate on additional post-processing and precision assessment performed on the October 2011 and October 2012 surveys. Removed section on “Comparison with IHO Standards”. Expanded table 5 to include additional bathymetry surveys and renamed the 2010 surveys so that they would be distinguishable (by file name) from the 2011 and 2012 surveys. ---------------------------------------------------- Revised and reposted June 18, 2015 Added three additional surveys (collected in 2013 and 2014) to abstract and introduction text. Updated table 1 with additional cruise IDs and dates. Added two paragraphs under Geodetic Control section describing the new POS MV inertial measurement unit (IMU) system used for the 2013 and 2014 surveys. Updated figure 4 to include POS MV. Added section under Estimates of Bathymetric Uncertainty entitled “Vertical Adjustments to Post-2010 Surveys”. Expanded table 5 to include additional bathymetry surveys. Corrected a typo in the metadata files for the four bathymetry surveys collected in 2011 and 2012-under the Digital Elevation Model Production Process Step the last sentence mistakenly stated that “The entire survey was shoaled by 6 cm to account for a bias…”. This was corrected to “The entire survey was deepened by 6 cm to account for a bias?…” ------------------------------------------------ Revised and reposted March 26, 2018 Added five additional bathymetry surveys (collected from 2015 to 2017). Updated table 1 with additional cruise IDs and dates. Updated figure 7 from bathymetric change from 2010 to October 2012 to bathymetric change from 2010 to October 2016. Expanded the second paragraph under “Estimates of Bathymetric Uncertainty” to include mean standard deviation values for all surveys collected to date. Added the last paragraph to expand upon tie-line statistics for the most recent surveys. Expanded the “Vertical Adjustments to Post-2010 Surveys” section to detail the most recent surveys. With the large number of bathymetry surveys now included, it was hard to keep track of the adjustments in the body of the text. We added table 5 to synthesis what is detailed in the body of the text and to provide an easy reference table for the end-user. Expanded table 6 to include additional bathymetry surveys. ------------------------------------------------ Revised and reposted June 24, 2020 Added two additional bathymetry surveys (collected from 2018 to 2019). Updated table 1 with additional cruise IDs and dates. Expanded second paragraph under "Data Collection" to describe increased coverage of Guadalupe Slough in April 2019 survey. Expanded the “Vertical Adjustments to Post-2010 Surveys” section to include the most recent surveys. Updated table 5 to include last two surveys Updated table 6 to include additional bathymetry surveys.
