6 TECHNICAL SURVEY SPECIFICATIONS BELIZE GENERAL 1. The Personnel of Belize Port Authority (BPA) will conduct survey operations in Motor Vessel (MV) SEA KING within the Belize City Harbour. This survey is the specific validated requirements of the BPA. The products will support the safe navigation of commercial, military, and recreational vessel operating in the area. The survey which is schedule to begin shortly is designed to collect high resolution singlebeam data with side scan sonar coverage, in selected area; in support of high and medium density Digital Bathymetric Databases (DBDB), full coverage digital side scan sonar (if available) in support of Shallow Water Tactical Ocean Data (SWTOD) and large scale NGA charts. AREA & SURVEY OBJECTIVES 2. Admiralty Chart # 522 and 959 comprises the area of this survey project. NGA Chart #28167 is also directly affected. The survey has been divided into two areas: Channel areas, and a Harbour area. See Annex A for coordinates. Each of these areas requires data collection to specific standards. Channel areas will require particularly careful attention, as will hazards to surface and submerged navigation (e.g. wrecks, shoals, reefs, and rocks). Technical reporting for survey operations is discusses in Paragraph 15 below as are other products expected from the survey. PRECEDENCE: 3. The order of importance for completion of the survey project is: (1) Channel Areas, and (2) Anchorage Areas, Close attention should be paid to the Data Collectibles Table 2-1, which details the types and importance of data to be collected and to the Data and Product List (Tables 3-1). LAWS OF THE SEA ITEMS 4. All operations for this project will be conducted within the territorial waters of Belize in the Belize City Harbour. SECURITY CLASSIFICATION 5. This survey is UNCLASSIFIED. DISTRIBUTION STATEMENT 6. Distribution is limited to BPA with information to be provided to UKHO and NGA. Other requests must be referred to the Ports Commissioner, Belize Port Authority. No information will be released to a third country/party without prior approval of the Ports Commissioner, Belize Port Authority. B6

7 PREVIOUS SPECIFICATIONS 7. These are the second specifications for operations in Belize; the first was conducted by NOAA through HYCOOP. 8. Prior Surveys: US Navy surveys. AUTHORITY AND RESPONSIBILITY 9. The Operations Manager is responsible for the overall execution of this survey. Any change to these specifications must be approved by the Ports Commissioner, Belize Port Authority. Some locations within particular survey areas may prove to be particularly hazardous for survey operations; especially single beam and side scan sonar operations around shallow coral reef areas. In these instances, the survey effort invested and acceptable platform risk with respect to the quality and extent of collected data may be significant. When the Officer in Charge of the survey is confronted with such a dilemma Operations Manger is to be contacted for guidance. The Operations Manager will reassess the charting and product requirements with respect to survey effort/risk and advise the Officer in Charge on the proper course of action. FOREIGN GOVERNMENT PARTICIPATION 10. Other GoH Project participating country with approval from the Ports Commissioner may assign two (02) Hydrographers and one (01) Electronic technician to participate in survey operations. DATA COLLECTION 11. Data Collection will include the acquisition of: Side Scan Sonar (if available & applicable), single beam (40 khz or 200 khz) data, Navigation Data, Conductivity Temperature and Depth (CTD), Sound Velocity profiles, Bottom Grab samples, Investigation of Hazards and Aids to Navigation, Coastal, Photography, and Geodetic Survey Information. Standards and instructions for the collection of each type of data are contained in the Appendices. See Table 2 for data collectibles and the appropriate appendices for each type of data. Tidal corrections using observed tides shall be applied to bathymetric data collected in depths of two hundred meters or less in accordance with the Tidal Planning Document for the project. OPERATIONS PLAN 12. Geodesy and Tides: As required, a geodetic and tidal team shall be deployed prior to the beginning of the survey operations to provide horizontal control and collect tidal datum data for the survey project. They will submit station descriptions, positions, and geodetic data as necessary. Survey operations may not begin until tides stations are established and running properly, as the use of observed tides in depths less than 200 meters is mandatory for this project. B7

8 CALIBRATIONS AND ACCURACY TESTS 13. All platforms using single beam sonar systems shall complete system calibrations (i.e. Bar check and Latency test) in accordance with manufacturer s specifications prior to beginning survey operations. Any significant discrepancies in results in comparison with prior tests shall be noted and reported. The accuracy of the Differential GPS system used for primary navigation on board MV SEA KING shall also be collected over and established geodetic control point. The results of both the single beam calibrations and the Navigation System Accuracy Test shall be included in the Technical Reports. SURVEY OPERATION SCHEDULING 14. Generally, the Priority One Areas in a region should be finished before surveying the Priority Two Areas and so forth. However, should diversion from one area of operation to another become necessary due to inclement weather to ensure good data quality, care must be taken to keep the data well organized. If inclement weather, equipment problems, and/or other unforeseen circumstances cause the survey effort to fall significantly behind schedule, or should operations proceed significantly ahead of schedule, the Officer in Charge shall notify Operations Manager for guidance as soon as it become apparent that significant impact to vessel s scheduling can be expected.

16 3. Maritime Claims and EEZ boundaries: All Survey operations will be conducted within the twelve (12) Nautical Mile Maritime Seas Limit of Belize, therefore, Maritime Claims and EEZ boundaries are not germane. ANNEX C: NAVIGATION 1. Positioning Control: Control will be by DGPS. 2. Survey Scale: Survey scale will be 1:25,000 for all survey areas. 3. Line Spacing: For conventional hydrography, the maximum distances between lines and IHO order of accuracy are shown below. Side scan sonar coverage verification is discussed in Annex E. Multi beam sonar (MBS) coverage as per IHO specifications. AREA TYPE BERTHING AREAS HARBORS, Channels AND ANCHORAGES IHO ORDER DEPTH RANGE 1* 0-4OM M SURVERY LINE SPACING 3X or 4x Ave. depth or 25m, with 100% Bottom Search 3X or 4x Ave. depth or 25m, with 100% Bottom Search MB OR SSS OVERAG E When or if applicable, 200% When or if applicable, 200% SSS RANGE SCALE 25M SURVEY SCALE 1:10,000 50M 1:25,000 Special order accuracy shall be obtained when possible. Refer to IHO SP Berthing & Anchorage Areas: As specified above in Annex A, Berthing Areas will be considered to include areas adjacent to the pier facing out to 100 meters from the pier face. Berthing Areas survey lines should be oriented parallel to the face of the piers and line spacing restricted to a maximum of 25 meters with 25m SSS Ranger Scale. 5. Cross Checks: The positional accuracy of soundings shall be established by running cross check comparisons perpendicular to the development lines, with a minimum of one (01) crosscheck passing through all development lines as outlined in Sec of IHO SP44 (for multibeam surveys) or 10x to 15x the development lines line spacing for singlebeam. Suspect sounding accuracy identified by cross check shall be resolved prior to accepting the data. B16

17 ANNEX D: BATHYMETRY 1. Bathymetric Swath Depth Data, if available/ applicable: Multibeam sonar swath depth information shall be collected on all development lines. Generally speaking, this will be in depths greater than 40 meters where side scan sonar data is no longer required. Multibeam data is a mission critical data collection requirement. Survey line spacing will be determined by the Officer in Charge and will provide for a minimum of 120 percent bottom coverage. Some data gaps or holidays may be permitted in depths over 200 meters. Survey speed should average knots to meet along track Imagery data requirements. The Officer in Charge will determine the extent of permitted data gaps and best operating speed. Swath Coverage Table Sonar Manufacture s Depth Ranger (m) Mode Swath Width RESON ONE RANGE 7.4x m; 4.2x to 100m; 2.7x to 150m; 2.0x to 200m; 1.6x to 250; 1.3x to 300m (below transducer) Crosscheck lines will be run to allow periodic checks on the bathymetric data collection. The Officer in Charge can modify the crosscheck spacing as required. 2. Data Processing: All survey data collected will be field processed, verified, and validated concurrent with survey operations. Verification method will include comparison of collected data to existing charts and prior surveys. The Officer in Charge shall verify that work conducted by different platforms and/or during different SURVOPS merges seamlessly with adjacent data sets. Processing priority will be given to sounding data. The Situation Report (SITREP) will include information as to data quality, items of discrepancy, and impact of weather conditions on the survey effort. Discrepancies discovered in field processing and verification should be resolved immediately to the satisfaction of the Officer in Charge. The Officer in Charge will bring discrepancies requiring significant additional operational time and effort to be resolved to the attention of the Ports Commissioner, for decision. Tide, draft, and sound speed corrections will be in meters and decimeters and will be applied to all soundings as part of the data coverage and quality for use in generating the official date sets by BPA. 3. Soundings: Soundings will be recorded in meters. Sounding will be corrected as required by section 4.9 of the NOAA Hydrographic Manual. BPA is requires velocity of sound corrections based on actual speed. Sound speed is derived from temperature, salinity, and depth from CTD observations collected in the survey area. A singlebeam depth sensor is sounding system used. The primary purpose of the shipboard single beam sonar will be sounding system used. The primary purpose of the shipboard single beam sonar will be set up and operated accordingly to meet this requirement. Single beam B17

18 soundings collected will require sound speed corrections using the sound speed profile collected in their geographic location. 4. Calibrations, if applicable: All multibeam calibrations (i. e. Patch Test) will be completed in accordance with manufacturer s specifications. Cross Check lines are to be used to indicate problems with the system s calibration. Inter-system Consistency Checks: Since this is not a multiple platform, multiple SURVOP project, Inter-system Consistency Check Areas (ICCA s) will not be required for system calibration. Instead, a suitable calibration area within the survey area will be used to conduct all multibeam calibrations as indicated. 5. Bathymetric Swath Imagery Data: NOT APPLICABLE 6. Imagery Processing: No field processing of imagery data is required. 7. Single Beam Sonar: All single beam sonar systems will be used in a not to interfere basis with the multi-beam data collection (if applicable). The SNR will decide frequency and use of all additional sonar systems. i. Single Beam Sonar 200 KHz: The 200 KHz sonar can be used in shallow water survey operations on a not to interface basis with multi beam operations. ii. Single Beam Sonar 40 KHz, if available: The 40 KHz sonar can be used in medium-to-shallow survey operations on a not to interfere basis with multi-beam operations. iii. Sub-Bottom 3.5 KHz Profiler, if available: NOT APPLICABLE: The 3.5 KHz Sub-Bottom Profiler should be adjusted to bring out sub-bottom layering. The equipment shall not be operated in less that 50 meters of water and shall be operated in the CW mode with a very short pulse length, low power setting (-36db), and manual receiver gain in depths to 100 meters, following as necessary to bring out sub-bottom layering. 8. Bioluminescence: Bioluminescence is the chemically based emission of light by living organisms. Bioluminescent displays may be classified according to their appearance. In general, the three (03) descriptive categories are sheet type, spark type, and glowing ball or globe type. A fourth category, exotic displays, is rarely reported. See reference, Fleet Oceanographic and Acoustic Reference Manual. Any bioluminescent activity observed is to be recorded on the Marine Observation Log (BPA form 3141/7). 9. Conductivity, Temperature, and Depth Measurements: Additional CTD observations may be required in areas with large temperature and/or salinity spatial and/or temporal variations. The CTD drops are generally required in the deepest depths of the survey area to ensure accurate profile information to the bottom. However, this does not preclude adequate spatial sampling. The CTD observations are to be spatially well distributed throughout the survey area. Close attention is required to ensure a CTD drop is in the vicinity of that day s survey operations. Additional drops will support multibeam sonar operations. B18

19 10. CTD Processing-Sound Velocity Profiles: CTD casts will be processed and the sound velocity profiles compared to others in the same general area. It is important to know and monitor the variations between the two. Poor derived sound velocity profiles will drive the need for more CTD stations. 11. Calibrations: If possible the CTD calibration should be checked against one of the following: i. Salinity from water samples processed with a salinometer. Salinity and sound velocity checked against another CTD drop. ii. Sound velocities checked against a recoverable, direct reading sound velocimeter. iii. Dual CTD casts. (Two instruments lowered at the same time and compared.) 12. Current Measurements, if available: When applicable, Current Meters will be operated continuously throughout the survey area when not in conflict with other sonar systems. Bottom-mounted current meters will be deployed for a minimum of 15 days, with optimal data collection to coincide with tide data collection for further tide/current analysis. Ideally, the current observations are to coincide with extremes of tidal movement during spring and neap tides (new/full moon and warning/waxing/quarter moon). Appropriate areas will be determined by the Officer in Charge with respect to safe navigation practice. 13. Sound Speed Measurements: Sound Speed will be calculated from CTD derived depth, temperature and salinity or other devices (Deployable Sound Velocimeter, Digibar, etc.)available during the survey. 14. Water Clarity, if available: If applicable, Secchi disc and K-Meter measurements are to be taken as required by the SNR. Measurements will be taken in accordance with HP 2.7.5: Water Clarity-Secchi Disc Measurements, October Water Color: If applicable, water color/discoloration may be recorded as required by the SNR. Discoloration may be due to shoals, plankton blooms, algae, shore runoff, pollution, etc. Water color is to be recorded in the Marine Observation Log (BPA form 3131/7, rev ) or its equivalent. B19

20 ANNEX E: SIDE SCAN SONAR AND BOTTOM CHARACTERIZATION Side Scan Sonar: IF AVAILABLE AND IF APPLICABLE 1. Data Collection: When applicable, the system will be used to support hydrographic survey operations in depths ranging between 3 to 40 meters. The Officer in Charge is authorized to achieve the best compromise between maximum data collection and data quality. Side scan sonar data shall be collected in all waters of less than 40 meters depth at line spacing. The side scan sonar towfish will not be towed at speeds in excess of 6 knots. The towfish height will be maintained above the seabed at percent of the range scale in use (i.e.., at 25 M range scale, between M above sea bed). If possible, side scan sonar lines are to be run within 20 degrees of the direction of the current of tidal stream to reduce uncertainty in tow fish position. Adjacent side scan sonar development lines shall be run in opposite directions to facilitate the positioning of any targets encountered. However, in areas where rapidly shoaling bottoms make this practice hazardous for equipment operations the Officer in Charge may determine that all lines should be run from shoal water out. In this event, the areas in which one-direction operations have been conducted shall be identified and noted in the technical reports. Gaps in side scan sonar coverage in depths less than 40 meters, which have been identified by coverage mosaics, shall be closed by running additional development lines. Side scan sonar operators shall maintain thorough operations logs noting start and end line times, data logging on or off, contacts encountered, line out, and other comments pertinent to the collection of this data. 2. Records and Processing: When applicable, all side scan sonar data will be converted to CARIS SIPS format for processing and analysis. Upon completion, the HDCS format will then be converted to Unified Sonar Image Processing System (UNISIPS) for filing in the BPA Database. Once side scan sonar data has been processed to HDCS CARIS format, it must be examined for bottom contacts/hazards. Using the tools provided in CARIS SIP, target files would be generated that contains detailed information on each bottom contact. These target files will then be used as input to the multibeam bathymetry CARIS HIPS multibeam Editor to ensure any multi beam returns in the vicinity of these targets that are not misidentified as noise. Target files are to be separately maintained files and shall be forwarded as part of the survey record. Both low and high-resolution mosaics will be generated. Lower resolution coverage mosaics are useful for providing a visual cue of what areas have been completed. Higher resolution mosaics should be created at least once each day or more frequently as necessary to support decision making with regard to recommended locations to acquire bottom samples and to provide a mechanism for checking data quality. Each mosaic should be examined as soon as possible after data is acquired to check for possible errors in the data B20

21 acquisition and processing system. Coverage and bottom characterization mosaic files shall be forwarded as part of the survey record. 3. Bottom Provincing and Sampling: When applicable, the location of bottom grabs will be based on analysis of the acoustic imagery mosaics generated from the side scan sonar data. The Officer in Charge will assist in side scan sonar image interpretation for this purpose and in the decision making process with regard to where the bottom samples should be taken. Should this prove impractical, the Officer in Charge shall determine the spacing and location of grabs based upon a study of available charts and the multibeam sonar record in order to obtain a comprehensive and spatially well distributed set of samples that can be used for charting purposes. Bottom samples shall be well documented following established procedures and the process by which the location of the samples was determined shall be included as part of the technical report. 4. Hazard Investigations and Reporting: All areas dangerous to both surfaces and subsurface navigation, including doubtful soundings, shoals and wrecks, whether discovered during the survey or appearing on existing charts, are to be fully investigated in accordance with HP Investigation of Shoals, Seabed Features, and Submerged Hazards, October The position of the least depth of all encountered shoals, obstructions and wreck will be reported to BPA and NGA by message. Where possible, the least depth shall be determined by multibeam sonar, if available. Otherwise, singlebeam least depth search survey should be conducted based on international standards. Any discrepancies, found in comparison to existing navigation charts and/or publications will be reported via official message to the BPA and to NGA via at navsafety@nga.mil. If available, side scan sonar shall be used to investigate any hazards to navigation (both surface and subsurface) encountered during survey operations in depths to 200 meters. Hazard investigations shall be conducted at no more than 50-meter range scale and at the highest frequency of operation available with the tow fish. Hazard investigation lines shall be run at the slowest speed possible over the target to provide the best resolution obtainable and shall be oriented both parallel to an perpendicular to the orientation of the longest axis of the target. Records of hazard investigations are to be maintained and submitted separately as part of the survey data record. The investigation of hazards and potential hazards are to be noted and reported in the technical reports. B21
