At 8:29, on the morning of Friday, November 30, 2018, a magnitude 7.1 earthquake shook Anchorage, Alaska, for thirty stressful seconds. It was the largest earthquake in Anchorage since the Good Friday Quake of 1964, and brought Alaska’s most populated city to a standstill as residents evacuated buildings and came to terms with what they had just experienced.
NOAA is initiating a five-year process to end all traditional paper nautical chart production and is seeking the public’s feedback via a Federal Register Notice published on November 15, 2019. Chart users, companies that provide products and services based on NOAA raster and electronic navigational chart (NOAA ENC®) products, and other stakeholders can help shape the manner and timing in which the product sunsetting process will proceed. Comments may be submitted through NOAA’s online ASSIST feedback tool.
If you have spent time on the water in Puget Sound, you have probably seen the large, distinct green and white vessels. These vessels move passengers, vehicles, and cargo across Puget Sound to the San Juan Islands and to Victoria, Canada, year round. They are a part of the Washington State Department of Transportation ferry system. The state has been operating ferries since 1951, and intended to run the ferry service until cross Sound bridges could be built. These bridges were never built, and the state continues to operate the ferries to this day. As of last July, there are 22 state-operated ferries on Puget Sound, with the largest vessel able to carry 2500 passengers and 202 vehicles.
One of these routes is a 30-minute transit from Coupeville, WA, to Port Townsend, WA, at the mouth of Puget Sound. This route carries roughly 820,000 passengers a year, and saves travelers from a five- hour drive around the Sound. n 2013 the Washington Department of Ecology and the Applied Physics Laboratory at the University of Washington installed instruments on board to measure the velocity of current at the entrance of the Sound. Due to the shallow depth of the ferry terminal at Coupeville, extreme (low) tidal conditions interrupt this ferry route up to three times a month.
NOAA’s Northwest and Pacific Islands Navigation Manager Crescent Moegling received a survey request from the Washington State Ferries in early summer of 2019 to survey this route. Following completion of a routine survey in Bellingham Bay, Navigation Response Team – Seattle (NRT-Seattle) along with augmenters Lt j.g. Joshua Fredrick, NOAA’s Center for Operational Oceanographic Products and Services, and Adrian Biesel, an intern at NOAA Office of Coast Survey’s Pacific Hydrographic Branch, traveled to Oak Harbor, Washington, on August 14. After safety and familiarization briefings, NRT-Seattle got underway from the Fort Casey State Park boat ramp daily to collect multibeam data. The team completed this request on August 19.
The density of the team’s data allows for confident detection of 1×1 meter objects on the seafloor. In addition to collecting information on the depth of the seafloor, the team also verified, investigated, and updated several features on the chart including but not limited to kelp beds, fog signals, and pier pilings.

On August 27, an international contingent from the United States (NOAA), the United Kingdom Hydrographic Office, and the Canadian Hydrographic Service participated in the S-100 sea trial in Busan, Republic of Korea.
S-100 is the International Hydrographic Organization’s (IHO) Universal Hydrographic Data Model’s framework standard from which a variety of product specifications can be developed for use within navigation systems and marine spatial data infrastructure. For many years, NOAA and the Ministry of Fisheries of the Republic of Korea have had a Joint Project Agreement and one of the projects is to develop and promote and S-100 test bed. This test bed is designed to help further the development of S-100 infrastructure used to develop S-100 related products and further the testing of S-100 interoperability within navigation systems.
Storms, particularly hurricanes, can be unpredictable. Therefore, NOAA’s hydrographic survey response teams that aid in the reopening of ports following storms, are designed to be flexible, proactive, and are on call 24/7 should the need arise to identify dangers to navigation.
For more than 50 years, NOAA Ship Rainier and its hydrographic survey launches have surveyed the Pacific seafloor. During this time, Rainier sailed thousands of miles, including the entire U.S. west coast, Alaska, and Hawaii. This year, Rainier expands on its traditional role of hydrographic survey and is supporting dive operations in the Northwest Hawaiian Islands and in the Papahānaumokuākea Marine National Monument. While Rainier is sailing these remote coral atolls, the survey launches — that are usually in its davits and deployed directly from the ship — are tasked to their own surveys around the islands of Maui, Moloka’i, and O’ahu.
NOAA’s Office of Coast Survey, the University of Southern Mississippi (USM), and Saildrone accomplished a key milestone in the research and testing of unmanned technology that can lead to enhanced seafloor mapping capabilities with the launch of the first Saildrone — a wind-driven and solar-powered unmanned surface vehicle (USV) — equipped with multibeam echo sounder technology in the Gulf of Mexico. NOAA anticipates the success of this mission and technical achievement will lead to mapping projects in the Arctic.
Last week, NOAA’s Office of Coast Survey held its third annual Nautical Cartography Open House welcoming over 250 attendees from the U.S. and abroad. Government agencies, industry and academic partners, and members of the public attended. The open house featured posters, presentations, tours, and exhibits centered around four themes: Bathymetric Databases, Custom Charting, Innovative Cartography, and Precision Navigation. Dr. Shachak Pe’eri, organizer of the event and chief of the Cartographic Support Branch in the Marine Chart Division, welcomed attendees in the morning and John Nyberg, chief of the Marine Chart Division, gave the keynote speech.
Ever wonder what it’s like to be a member of the NOAA Coast Survey team? We use the Coast Survey spotlight blog series as a way to periodically share the experiences of Coast Survey employees as they discuss their work, background, and advice.

“The hydrographic data we acquire and review adds to the scientific knowledge of the seafloor and is valuable to other agencies to simulate sea level effects on coasts, identify sensitive marine habitats, and select alternative energy sites, among many other uses.”
