Strategically placed around the country, NOAA’s navigation response teams―30-foot survey vessels with a three-person survey team―maintain emergency readiness while checking chart accuracy in changing ports and harbors. Navigation response teams work day-to-day in ports and harbors, collecting data to update the nation’s nautical charts. They measure depths, locate obstructions, report dangers to navigation, and update features for safe navigation. Whether there is a need to investigate wrecks, check for suspected shoals, conduct surveys for coastal management, or work with other federal agencies to support homeland security, Coast Survey’s navigation response teams have the expertise to get the job done safely and efficiently.

Nautical charts are updated with the most current information available through several processes and workflows within NOAA’s Office of Coast Survey. The large majority of these updates consist of revisions to water depth information. The bottom of a water body is changeable by nature, thus hydrographic surveys are constantly necessary to show contemporary depths in a given body of water. What doesn’t happen quite as often are changes to land along the coast, altering the way inlets, harbor entrances, and river mouths appear from a bird’s eye view. Unless there has been a catastrophic event, these changes in land are usually the result of human interaction.

Flushing Bay Channel Lighted Buoy 3 was struck by a tug and barge in late July, and was reported sunk immediately following the strike. The buoy marks the entrance to a channel frequented by commercial barge traffic, specifically, loaded fuel barges bound for LaGuardia International Airport. The Navigation Response Branch (NRB) was called upon in early August to assist United States Coast Guard (USCG) Sector New York in locating the sunken buoy in Flushing Bay, New York.

This week NOAA’s Office of Coast Survey concluded its hydrographic survey response following Hurricane Delta. At the immediate request of the U.S. Army Corps of Engineers (USACE), NOAA’s navigation response teams (NRTs) and NOAA Ship Thomas Jefferson surveyed areas within the Gulf Intracoastal Waterway (GIWW), Calcasieu Ship Channel, and the entrance to the channel. With lessons learned from the response to Hurricane Laura — the first major hurricane of the 2020 season and the first hurricane response during a pandemic — the teams and Thomas Jefferson successfully collected, processed, and delivered data to the USACE, identifying significant hazards to navigation and helping to ensure the timely reopening of waterways.

Hurricane Laura, the first major hurricane of the 2020 Atlantic Hurricane Season, made landfall over Louisiana in the early morning hours of Thursday, August 27. As a Category 4 storm and with maximum sustained winds reaching 150 miles per hour, it caused significant damage along the Gulf coasts of Louisiana and southeastern Texas. For NOAA’s Office of Coast Survey – whose job it is to identify dangers to navigation and help speed the reopening of ports and waterways following severe storms – this marked the first hydrographic survey response effort of the hurricane season.

This week, NOAA’s Office of Coast Survey released the Mapping U.S. Marine and Great Lakes Waters: Office of Coast Survey Contributions to a National Ocean Mapping Strategy. This report is part of NOAA’s ongoing commitment to meet core surveying and nautical charting mandates while supporting broader needs to fill gaps in seafloor mapping and environmental sciences.

NOAA’s Office of Coast Survey, United States Coast Guard (USCG) Sector Honolulu, State of Hawaii Department of Transportation and United States Army Corps of Engineers (USACE) Honolulu Division established a memorandum of understanding (MOU) outlining each signatory’s area of responsibility in the event of a disaster in the Hawaii region. The intent of the MOU is to improve the efficiency and effectiveness of response efforts and speed the reopening of the ports and waterways following an emergency.

For more than 200 years, nautical cartographers have methodically charted our nation’s coastline, adding new features or hazards and updating meandering shorelines, all in an effort to aid safe navigation. However, occasions do arise that require immediate charting, particularly in response to national emergencies. Notable examples include charting the projected oil spill zone during the Deepwater Horizon oil spill disaster, as well as hazards during hurricane response efforts. Most recently, NOAA’s Office of Coast Survey was called upon to support the arrival of USNS Comfort to New York City.

There is a risk factor when navigating in and out of our nation’s busiest ports, particularly at the helm of some of the world’s largest deep draft vessels. Mariners rely on tide and water level information, wind and weather data, but perhaps most importantly, they rely on electronic navigational charts and the quality of depth measurements that comprise them. Recently, NOAA’s Office of Coast Survey certified the U.S. Army Corps of Engineers (USACE) hydrographic surveys for the Pinole Shoal Channel in San Francisco Bay — a critical waterway for bulk carriers and tankers to reach the ports of Sacramento, Stockton, Martinez, and Benicia — the highest possible data quality rating, Category Zone of Confidence (CATZOC) A1, for two years. This is the first USACE federally-maintained channel to receive the highest-level certification. NOAA anticipates the increased CATZOC rating will dramatically increase shipping efficiency.

NOAA’s Office of Coast Survey collaborated with U.S. and Canadian mariners, the Lake Carriers’ Association (LCA), and the Canadian Chamber of Marine Commerce (CMC) to update the Recommend Courses in Lake Erie and transfer them from paper charts to NOAA electronic navigational charts (NOAA ENC®). This bi-national effort involved compiling and updating information for Lake Erie’s 75 routes which span both U.S. and Canadian waters. These routes cover 20 NOAA and five Canadian ENCs.
