30 July 2004USM 2004 Upper Pearl Survey Purpose Why conduct this particular survey? –Provide practical experience to cement theoretical knowledge –Extend USM’s dataset from the I-10 bridge northward –GET A DEGREE!!!

30 July 2004USM 2004 Upper Pearl Survey History Site Selection –Potential sites selected during Dave Dodd’s, Hydro Data Mngt Course Upper Pearl (I-10 to SSC) Lower Pearl (Hwy 90 to St. Joe’s Pass) Bayou Caddy/St. Joe’s Pass –Upper Pearl selected for: Complexity Proximity to SSC Data uses (USM, NAVO, SBT)

30 July 2004USM 2004 Upper Pearl Survey Survey Area I-10 SSC

30 July 2004USM 2004 Upper Pearl Survey Hydrographic Survey Specification USM Initially written during HYD608 Group 2’s HSS selected as most complete, updated by group at the beginning of the survey. Final HSS: USM

30 July 2004USM 2004 Upper Pearl Survey HSS: Major Sections Append 2: Tidal Data –3 Tide Gauges (SBT Quaywall, Hancock Pier, I-10) –30 days of data collected –Weekly observations –Reduce soundings to MLLW Append 3: Wreck List –No known wrecks

30 July 2004USM 2004 Upper Pearl Survey HSS: Major Sections Append 4: Geodetic Data –Data referred to NAD83 (equivalent to WGS84 for charting) –Landmarks referenced to NAVD88 –PPK positioning (Order 1 accuracy) Append 8: Specific Charting Info. Requirements –All soundings, ATONS, and shoreline features will be delineated to Order 1 standards –All Landmarks within visual site of the river will be positioned –All Aids to Navigation will be located and described –Report discrepancies for Aids to Navigation to the local U.S. Coast Guard District (District 8)

30 July 2004USM 2004 Upper Pearl Survey HSS: Major Sections Append 9: Oceanography –Sound Speed CTD casts will be taken 3 X daily aboard the Bertram SVP casts will be taken 3 X daily aboard the Skiff SVP corrections will be applied onboard for Bertram and within CARIS for the skiff –Multibeam 10 % overlap required –Single-beam 25 m line spacing for development lines and 250m line spacing for cross-check lines –Ancillary data: Secchi and bottom grab data will be collected daily
