A MBES buffer line was collected to help define the inshore 4m curve where practical. The R2 Sonic 2024 MBES was used for least depth developments, and in larger areas of numerous SSS contacts. There were ongoing dredging operations, at the beginning of the survey, in the approach to the USN Station Mayport, however survey work in this area was collected post-dredge operation. There was a tropical Storm in the area prior to starting the survey, ATON were off in some instances as a result of this weather, resulting in some ATON being positioned twice, after the USCG reset these ATON. In those instances the first positions, were rejected, in the data, when new positions were acquired after reset. Heavy shrimp trawling were ongoing offshore, in the survey area, during the survey, notable trawl tracks can be seen in the SSS data where these action have taken place. The 200% SSS coverage allowed for area that were slightly effected by noise in the water column, due to biological noise, and trawling, to be evaluated antiquity. 30.414502111181.315258833330.369219222281.46203061111Survey Limits H12407file:///P:/Caris_Net_Active_Projects/S-G901-NRT2-2012/H12407_A/Support_Data_Field/Descriptive_Report/Report_Body/Other%20DR%20Support%20files/H12407%20Survey%20Limits.jpgJacksonville is a MTS port and is in need of updating the bathymetry on the nautical charts. The last surveys in the area are from 2002 and 2003. The Jacksonville Docking Pilots have requested a hydrographic survey in Anchorage Area "B", south of Long Beach Range. It is the intent of this survey to supersede all bathymetry, seafloor features, and bottom characteristics within the assigned survey area as defined by these instructions for updating of NOAA charts 11489, 11490 and 11491. The N.A.L.L. line for this project is defined as the 4 meter depth contour.The entire survey is adequate to supersede previous data.200% SSS coverage with concurrent VBES, and supplemented with MBES development were acquired.Survey Limits were acquired in accordance with the requirements in the Project Instructions and the HSSD.2H12407 Survey Coveragefile:///P:/Caris_Net_Active_Projects/S-G901-NRT2-2012/H12407_A/Support_Data_Field/Descriptive_Report/Appendices/III.%20Final_Progress_Sketch_&_Survey_Outline/H12407_Survey%20Coverage.jpgUS Navy requested work inside the USN Station Mayport was conducted consisting of 200% SSS, and >100% MBES coverage were acquired for this request, as well as ATON positions.3USN workfile:///P:/Caris_Net_Active_Projects/S-G901-NRT2-2012/H12407_A/Support_Data_Field/Descriptive_Report/Report_Body/Other%20DR%20Support%20files/H12407%20USN%20coverage.jpg2012-06-192012-06-282012-07-242012-08-022012-08-072012-08-082012-08-092012-08-142012-08-152012-08-202012-08-212012-08-222012-09-112012-09-122012-09-262012-09-272012-10-02454903.8331210110.78129.960.000.000.000.00110.7911.960.00110.78129.960.000.000.000.00110.7911.960.005.0NAShoreline was investigated in accordance with the Project Instructions and the HSSD.Bottom Samples were acquired in accordance with the Project Instructions or the HSSD.Refer to the Data Acquisition and Processing Report (DAPR) for a complete description of data acquisition and processing systems, survey vessels, quality control procedures and data processing methods.

The Eastern junction of H12407 is 3-10 feet deeper than the survey data from H-11091, for the most part seaward of the jetty offshore entrance. Soundings throughout the rest of the survey area are currently on the order of 3-5 feet deeper than previous survey soundings. Soundings on the Western limit of H-12407 show commonality with those of H-11091 with 1-2 feet, with H-12407 still showing deeper soundings. Survey H-10793, 1998, overlaps the survey area of H-12407,2012 offshore of the jetties entrance. In general the sounding agreement outside of the shipping channel compare on the order of 1-2 feet, with H-10793 showing the deeper soundings. Soundings from H-12407 appear to be shallower than H-10793, within the shipping channel by 2-3 feet East of 081°20'35.67" W; while soundings due West from this point inside the channel were found to be 5-10 feet deeper, at present. Note should be made, that there have been several major weather events, in this area, during this time span; as well as several dredging operation, with current plans to deepen the channel to the 50ft range. The surveying Hydrographer recommends that all sounding data for H-12407, supersede previous charted data.7H-11091 Junction to Eastfile:///P:/Caris_Net_Active_Projects/S-G901-NRT2-2012/H12407_A/Support_Data_Field/Descriptive_Report/Report_Body/Other%20DR%20Support%20files/H11091%20Junction%20E.jpg8H-10793, 1998 offshore Junctionfile:///P:/Caris_Net_Active_Projects/S-G901-NRT2-2012/H12407_A/Support_Data_Field/Descriptive_Report/Report_Body/Other%20DR%20Support%20files/H-10793%20Junction%20South.jpgSonar system quality control checks were conducted as detailed in the quality control section of the DAPR.None ExistThere were no conditions or deficiencies that affected equipment operational effectiveness.None ExistThere were no other factors that affected corrections to soundings.Sound Speed Cast Frequency: VBES Data: Normally, daily cast were taken for each day of survey acquisition with a Digi Bar Pro SVP. Dual cast were taken, with 2 SVP Probes, weekly for a DQA on the SVP instrument, all passed. MBES Data: Normally a starting daily cast was taken at the beginning of work, and subsequent cast were taken during the survey day, when location, or variances of surface speed were observed to deviate greater than 2m/s, with a closing of day cast preformed as well. See "H12407.DQA.txt" located in the Separates II. A total of 34 SVP cast were taken during this survey. A SVP Report can be located in the Separates II. as well.There were some area of notable water mass mixing, predominantly at the Jetty Entrance. and to a lesser degree at the Western limit of the sheet where the ICW transects the St Johns River near 30.38613492 , -081.46149185. The zoning was provided as a TCARI grid from COOP, and was used as is. Full water column cast were taken in the direct survey area planned for that days work.

Strong alongshore current s were noted crossing the channel at the entrance to the Jetties, from North to South. These currents, in the 2-3kts range are sheared by the flood and ebb tidal currents running perpendicular to these alongshore currents, causing confused sea states at times of maximum Ebb flow (Ebb flow observed normally at 6kts). Note was made that the strongest Ebb flow occurs along the Southern side of the river.Present and/or planned construction or dredging exists within the survey limits, but was not investigated.No new surveys or further investigations are recommended for this area.No new insets are recommended for this area.As Chief of Party, Field operations for this hydrographic survey were conducted under my direct supervision, with frequent personal checks of progress and adequacy. I have reviewed the attached survey data and reports.All field sheets, this Descriptive Report, and all accompanying records and data are approved. All records are forwarded for final review and processing to the Processing Branch.The survey data meets or exceeds requirements as set forth in the NOS Hydrographic Surveys and Specifications Deliverables Manual, Field Procedures Manual, Standing and Letter Instructions, and all HSD Technical Directives. These data are adequate to supersede charted data in their common areas. This survey is complete and no additional work is required with the exception of deficiencies noted in the Descriptive Report.Haveing the Pydro PSS open during review of this DR is highly suggested, as it will provide a better presentation of data for review.Robert W Ramsey Jr, CHChief of
