Office of Coast Survey FY16 Update

This presentation discusses the importance of maintaining accurate waterway and coastal charts, with a focus on addressing shoaling issues and improving chart usability. Topics include the use of unmanned surface vehicles, crowdsourced and satellite-derived bathymetry, as well as efforts to update and validate charts for the Great Lakes region. The goal is to provide mariners with reliable and efficient charting systems for a better navigation experience.

  1. Office of Coast SurveyFY16 Update Presented by Rear Admiral Shep Smith August 30, 2016

  2. Undertaking a blended solution Supporting maritime economies

  3. Waterways and coastal communities • Over 2,000 reports of shoaling on NOAA charts • mostly in less than 4m of water • reports come from vessels • often as the result of groundings or near-groundings • concentrated near harbors, inland waterways, and ocean inlets • For most of these applications, the “too shallow to worry about” limit is 1-2m

  4. Waterway and coastal charts need attention • Hudson River • Multi-year project • BHII & NRT5 • Riverhead Production Platform Facilities • New ENC • Larger scale coverage • Yukon River • Annually-revised ENC • Uses satellite-derived bathymetry Saugerties to KingstonBay Hydro II

  5. Complementing the traditional hydrographic survey Accessing a world of data

  6. Unmanned surface vehicles Crowdsourced bathymetry Satellite-derived bathymetry RosePoint beta test: Coastal Explorer feature • Automated access to partners’ data • U.S. Coast Guard Aids to Navigation database • U.S. Army Corps of Engineers channel database (eHydro)

  7. Lake Huron collaboration • Great Lakes Environmental Research Laboratory and the Thunder Bay National Marine Sanctuary provided vessel & equipment • Coast Survey provided two physical scientists • Among the last areas in NW Lake Huron needing modern surveys

  8. Continuing to apply new shoreline Applying topobathy lidar from NGS Remote Sensing Division to Great Lakes charts

  9. Getting the right product to the customer as efficiently as possible IMPROVe mariners’ chart experience

  10. Tens of thousands Hundreds of thousands A million Tens of millions

  11. Improve usability • Distribute products in standard formats • For charting systems, portable pilot units and port information systems • Make chart system simpler • Support faster updates • Weekly updates • RNC Tile Service

  12. This is what we hear about ENCs Too many alarms, not sufficient attribution Discontinuity where it should be “seamless”

  13. Making progress on Great Lakes ENCs • Will be completed in 2017 • Most of the shoreline will be updated

  14. Validating “recommended courses” across Great Lake charts Mismatched edges between charts Traffic not aligned with charted course

  15. Coast Survey Regional Navigation Managers
