1. Notes

Minor changes, i.e. informative and/or already implemented in tools/versions currently in use.  For NOAA ISD, unless notified otherwise by the HSD/NSD project manager, these changes are applicable as of the date of publication.

• 1.5 Quality Metric Framework
  • Added asterisk to Table 1.5.0 Quality Metric Framework to clarify alignment in terms of feature detection.
• 4.2 Raw Data Submission
  • Added additional asterisk to Table 4.2.0 to list the requirement that only water column data files used to aid in feature detection (i.e. to attain a safer least depth) must be sent to the Office of Coast Survey. Water column data acquired for any other reason must be sent directly to NCEI.  
• 6.10 User Overrides
  • Removed the external link to the Field Procedures Manual for guidelines on selecting designated soundings, since that reference does not contain this information.
• 7.4 New Features
  • Added clarification to the term previously uncharted (in the context of determining new features) and that this assessment is done in reference to the largest scale overlapping chart. 
• 7.5 Feature Disprovals
  • Removed categorizations of positional and depth Unverified Charted Features (UCF), and for feature disproval purposes, positional UCF are simply UCF, and depth UCF are treated just as any other feature.
• 9.0 Physical Seabed Samples
  • Edited so that it is required for Field Units to develop their own sampling plan based on the total number of samples assigned in Project Instructions, data acquired during survey operations, and areas of potential vessel anchoring.*
• 13.1 Metadata
  • Added link to Appendix 2 which describes the entry of survey and grid specific metadata as required in this section.
• 14.0 Survey Findings
  • Replaced uses of General Locality with Project Name.*
  • Replaced uses of Project Number with Project Unique ID.*
  • Added clarification that the following terms are synonymous and used interchangeably for NOAA ISD:
    • Sub-locality and Survey Name*
    • Registry Number and Survey Unique ID*
• 14.1 Report of Survey
  • Added requirement that Field Units must list the version of Hydrographic Survey Specifications and Deliverables (HSSD) that the survey adheres to.*
• 14.3 Dangers to Navigation
  • Edited so that the required chartlet image portraying the feature has the least depth sounding shown in meters.*
• 14.5 Seep and Pipeline Reports
  • Edited to clarify that contractor submissions of non-dangerous, exposed pipelines to the Office of Coast Survey must be uncharted.*
• 14.6 Survey Findings
  • Removed requirement to list the submission and date of submission for potentially sensitive data findings in the Supplementals section of the Report of Survey.*
• 15.1 Weekly Progress Reports
  • Changed format to JSON, with new requirements for submission of the JSON file(s), including a new contact email address.*
  • Added link to Appendix 1 which contains the updated information that must be included in the weekly progress report.* 
  • Added submission requirements and acceptable formats for the depth raster and moved naming convention to Section 16.*
  • Removed requirement that NOAA Field Units must use the Pydro Tool Scribble.*
• 15.2 Final Progress Report
  • Added requirement to report Total Number of physical seabed samples collected, XBTs used, and if applicable, aggregated transit data LNM.*
  • Removed requirement to report Total Number of Addressed Unverified Charted Features.*
• 16.2 Naming Conventions
  • Edited the WKT file name requirement to include #of# suffix in Table 16.2.0.*
  • Added the weekly progress report file name requirement to Table 16.2.2.*
• 17.3 New/Updated Features
  • Removed criteria for charted line or area features to be included as descrp = "update".
• Appendix 1. Progress Report Information
  • Added Appendix 1 which shows the information required to be in the weekly progress reports as described in Section 15.1.*
• Appendix 2. Metadata Attribution Guide
  • Added Appendix 2 which describes the entry of survey and grid specific metadata as required in Section 13.1.

* For NOAA ISD only.

Major changes, i.e. may require tools/version update. For NOAA ISD, unless notified otherwise by the HSD/NSD project manager, these changes are applicable at the start of the 2025 field season.

• 13.1 Metadata
  • Added conditional metadata attribute "Personnel" to allow for acknowledging personnel who contributed to the survey.
• 13.3 Quality Control Procedures
  • Edited so that only the methodology of junction analyses must be reported in this section, and not the actual results of the analyses.
• 14.1 Report of Survey
  • Edited so that the results of the junction analyses must be reported in this section.*
• 16.1 Folder Structure
  • Edited the folder structure to include additional sub-folders under Metadata.*
  • Added requirement that the folder structure must not contain extraneous folders or files at the uppermost three levels, with the exception of transmittal files which may reside at the level of <Project Unique ID> or <Survey Unique ID>.*

* For NOAA ISD only.

Minor changes, i.e. informative and/or already implemented in tools/versions currently in use.  For NOAA ISD, unless notified otherwise by the HSD/NSD project manager, these changes are applicable as of the date of publication.

• HTML version
  • Adjusted properties so that all links to external references open in a new tab.
• 5.7 Cleaning
  • Replaced usage of spurious soundings with non-bathymetric data and included examples of what might constitute non-bathymetric data.
• 6.3 Required Metadata
  • Added requirement that BAG start and end dates must be the same for each BAG associated with the Unique Survey ID and the Survey Metadata, with one exception, which is if the grids were divided based on known temporal changes.
• 7.4 New Features
  • Added clarification that multiple, discrete features in close proximity may be submitted as a single area feature for expediency, even if the horizontal dimensions of the area feature are less than 8.0 mm at the largest scale overlapping chart.
• 14.5 Seep and Pipeline Reports
  • Added requirement that Field Units must contact the OCS Project Manager and/or COR and Navigation Manager to discuss the appropriate points of contact, if the contacts are not listed in the Project Instructions.
• 16.2 Naming Conventions
  • Added naming convention and example for an MBAB mosaic that has multiple vessels/systems on the same frequency from relative or absolute calibrations.
