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.

NOAA’s Office of Coast Survey quickly updated NOAA electronic navigational charts (NOAA ENC®) to accurately reflect the 225 foot expansion of a slip in Port Everglades, Florida. Now at a total length of 1,125 feet, the elongated slip allows larger ships to dock with confidence. The Port Everglades Pilots – maritime pilots who maneuver ships through crowded harbors and confined waters – requested the chart update. With ENCs that accurately reflect the slip expansion in their hands, pilots can easily communicate to vessel captains that it is safe to dock their vessels in the slip.
NOAA Office of Coast Survey released its 1:12,000 electronic navigational chart (NOAA ENC®) of the Merrimack River, Massachusetts, in the RNC Tile Service. This is the first time a navigational chart—created solely as ENC product—is included in the tile service. The tile service renders a traditional depiction of the nautical chart for use with GPS-enabled electronic chart systems or other “chart plotter” display systems to provide real-time vessel positioning for recreational mariners. This chart is included in the single chart tile sets and the quilted tile sets both in the online and offline versions. Continue reading “NOAA RNC Tile Service displays first ENC-only product”
For the NRTs, this meant traveling hundreds of miles with a survey vessel in tow, facing challenges such as locating fueling stations, finding available lodging, and finding opportunities to rest. For the mobile integrated survey team (MIST), which is available to travel anywhere in the U.S. when hydrographic survey assistance is needed by the U.S. Coast Guard (USCG) or U.S. Army Corps of Engineers (USACE), this meant finding transportation to a disaster area and a “vessel of opportunity” to survey from once there.

NOAA’s Office of Coast Survey maintains the nautical charts and publications for U.S. coasts and the Great Lakes. This is over a thousand charts covering 95,000 miles of shoreline and 3.4 million square nautical miles of waters. Measuring depths and determining new dangers to navigation in this large area is a monumental job given the seafloor is constantly changing.
One of NOAA Coast Survey’s biggest tasks during the winter months is to plan hydrographic survey projects for the coming field season. Survey planners consider requests from stakeholders such as marine pilots, local port authorities, the Coast Guard, and the boating community, and also consider other hydrographic priorities in determining where to survey and when.

The Inner Harbor Navigation Channel in New Orleans facilitates the transportation of tens of millions of tons of cargo each year. Since the channel was recently closed for repairs, a temporary Chandeleur Sound Alternate Route was established to ensure the flow of commerce between the western and eastern reaches of the Gulf Intracoastal Waterway. NOAA experts assisted with the alternate route development in various ways, collaborating with the U.S. Coast Guard, U.S. Army Corps of Engineers, and the maritime industry.
Over the past few decades, mariners have witnessed the rapid development, reliability, and availability of e-navigation components, such as the global positioning system (GPS) and electronic chart display and information systems (ECDIS). These systems, and other technology, have fundamentally changed mariners’ reliance on traditional navigation services. In addition, the ability to manage data and information provided to the mariner through the automatic identification system (AIS) and cellular service has enhanced the interconnectivity between shore side information providers and shipboard users. These technological advances and data flow will help the mariner receive data, transmit data, and generally improve bridge resource management, situational awareness, and navigational safety.
Coast Survey’s navigation response teams, which are 3-person hydrographic survey teams on small boats, have made a fast start on this year’s survey season.
In Florida, where Coast Survey is preparing to issue a “new and improved” Miami Harbor Chart 11468 to alleviate vessel congestion at the Port of Miami, a navigation response team finished final hydrographic surveys to ensure the new chart has the latest and most accurate depth measurements around several areas identified as critical within the port. In just ten days, team members Erik Anderson, James Kirkpatrick, and Kurt Brown acquired, processed, and submitted the multibeam survey data covering 64 nautical miles.
