As e-Navigation becomes more popular, mariners are provided with streams of maritime data from multiple sources that allow them to more safely and efficiently navigate the seas. However, as the amount of information and number of sources grows, there is a need to standardize the data so it can be easily integrated and seamlessly displayed on navigation systems. Later this year, the International Hydrographic Organization (IHO) will publish edition 4.0.0 of S-100 – Universal Hydrographic Data Model. S-100 is the IHO’s framework for the standardization of maritime data products such as high resolution bathymetry, surface currents, marine protected areas, and the new standards for electronic navigational charts (ENCs).

Today NOAA announces the end of a testing phase in the development of a new crowdsourced bathymetry database. Bathymetric observations and measurements from participants in citizen science and crowdsourced programs are now archived and made available to the public through the International Hydrographic Organization (IHO) Data Centre for Digital Bathymetry (DCDB) Data Viewer. The operationalized database allows free access to millions of ocean depth data points, and serves as a powerful source of information to improve navigational products.
The U.S. federal channel in the Delaware Bay is vital to maritime commerce, leading deep draft vessel traffic to and from the major ports of Wilmington, Delaware, Philadelphia, Pennsylvania, and Camden, New Jersey. To navigate this federally maintained waterway safely and efficiently, mariners rely on the surveyed depths displayed on nautical charts. The U.S. Army Corps of Engineers (USACE) Philadelphia District regularly surveys this area, utilizing sophisticated techniques and equipment to map the depths of the seafloor. NOAA’s Office of Coast Survey, in turn, adds quality classifications to these channel depths and displays them on the nautical chart.
The portion of the federal channel from Newbold Channel Range down to the mouth of the Delaware Bay is the first waterway in the U.S. to have an improved quality classification assigned to USACE survey data—category of zone of confidence (CATZOC) A2. Improving survey quality and upgrading the CATZOC classification allows operators to accommodate smaller margins of error while still ensuring that navigating maritime approaches and constrained environments remain safe. These decreased tolerances allow ships to maximize their loads, ultimately increasing inbound and outbound cargoes.
NOAA Coast Survey recently released updates for two NOAA electronic navigational charts (NOAA ENC®) in the Port of New York and New Jersey, which added a permanent grid system overlay to anchorages in Bay Ridge, Graves End, and Stapleton. Coast Survey performed the update at the request of the Harbor Operations Steering Committee and collaborated with the Sandy Hook Pilots Association and U.S. Coast Guard (USCG) Sector New York’s Vessel Traffic Services (VTS).
A prototype version of a powerful new online tool, NOAA Custom Chart, is now available for boaters and other nautical chart users. The application enables users to define the scale and paper size of custom-made nautical charts centered on a position of their choosing. Once the functionality of this prototype is fully developed, NOAA Custom Chart will be an easy way for boaters to create a paper or digital back-up for the electronic chart system or other GPS-enabled chart display that they are using on board.
NOAA’s Office of Coast Survey is the federal leader in emergency hydrographic response. Consecutive strong storms during the 2017 hurricane season made response efforts challenging, and emphasized the importance of having a well-trained and versatile staff. Coast Survey’s regional navigation managers, navigation response teams (NRTs), and mobile integrated survey team (MIST) worked with partners before and after the storms to quickly and safely reopen ports and waterways.
The MIST equipment is a mobile, quick-install side scan and single beam sonar kit that can be quickly set up on a vessel of opportunity. Recently, Coast Survey sent the MIST team to Astoria, Oregon to conduct a hydrographic survey of the Mott Basin area, which the U.S. Coast Guard (USCG) requested to confirm charted depth and obstruction data.

Recently, NOAA navigation response team 5 (NRT5), responded to a survey request from U.S. Coast Guard (USCG) Sector New York following several groundings near Rockaway Point in Queens, New York. Waves and currents often influence the size and shape of nearshore sandbars, and the USCG was concerned that a sandbar may have expanded beyond the area depicted on the nautical chart. Lt. j.g. Dylan Kosten, Eli Smith, and Michael Bloom traveled from New London, Connecticut, to Jersey City, New Jersey, to launch their vessel and start the survey of the area.
On March 12, 2018, NOAA Coast Survey’s navigation response team 5 (NRT5) located the T/V Captain Mackintire, an 80-foot towing vessel that sank off the coast of Kennebunkport, Maine. The U.S. Coast Guard requested assistance finding the vessel, citing concerns of environmental hazards due to an unknown amount of fuel remaining onboard.
NOAA’s navigation response team 2 (NRT2), homeported in Fernandina Beach, Florida, conducted a survey around the Sunshine Skyway Bridge, which spans Tampa Bay. The U.S. Coast Guard (USCG) and additional members of the Tampa Bay Harbor Safety Committee requested the work and expressed interest in establishing alternate routes for recreational boating traffic. Alternative routes will alleviate increasing congestion where the main ship channel passes beneath the bridge. This area is naturally restrictive to navigation and, as a result, there have been multiple accidents and near accidents here in the past.Continue reading “NOAA surveys for recreational boat traffic safety in Tampa Bay”
