As NOAA Ship Rainier underwent repairs in South Seattle, the ship’s survey launches and their crews carried out a project to update nautical charts around the Port of Everett and its approaches in Possession Sound. The boats used state-of-the-art positioning and multibeam echo sounder systems to achieve full bottom coverage of the seafloor.
The ports of Seattle, Tacoma, and Everett have experienced an increase in vessel traffic and capacity within the last decade. The Port of Everett serves as an international shipping port bringing jobs, trade, and recreational opportunities to the city. Across Possession Sound, Naval Station Everett is the homeport for five guided-missile destroyers, and two U.S. Coast Guard cutters. The data collected from this project will support additional military traffic transiting to and from Naval Submarine Base Bangor in addition to the Washington State Ferries’ Mukilteo/Clinton ferry route, commercial and tribal fishing, and recreational boating in the area.

At the request of the NOAA Great Lakes Environmental Research Lab (GLERL), NOAA’s Office of Coast Survey deployed a survey team and a newautonomous surface vehicle (ASV) to gather hydrographic data in and around the narrow causeway inlets that dot the Lake Champlain basin in Vermont. GLERL will use the data to improve flood forecast models and analyze flood mitigation strategies in the Lake Champlain-Richelieu River system as part of a U.S. and Canada study led by the International Joint Commission.
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.

Knowing that the products we provide to the mariner community is essential to safe navigation for commerce gives me a sense of accomplishment.

The work we do has real value and every sounding takes a team of professionals from multiple disciplines. I like being a part of something greater.
On Thursday, June 21, we celebrate World Hydrography Day. This year’s theme—Bathymetry – the foundation for sustainable seas, oceans and waterways—is very timely as many hydrographic organizations worldwide are focusing on bathymetry at local and global scales. While we work to perfect real-time data and high-resolution bathymetry for ports, we are still working to build a foundational baseline dataset of the global seafloor. Our work at both scales have implications for the local and global economies.
Nowadays, many cars have sensors, video cameras, and other technology installed to help drivers park in tight spaces. Now imagine you are trying to parallel park a tractor-trailer on an icy hill, against a strong crosswind, with millions of dollars of products that depend on your precise execution. Dynamic conditions, tight spaces, and high stakes are exactly the scenario that many commercial vessels face as they move 95 percent of the United States’ foreign trade in and out of U.S. ports and waterways. In a manner comparable to the way car technology supports drivers, NOAA has launched a new program to develop the next generation of marine navigation tools that provide mariners with the information they need to safely and efficiently transport maritime commerce. This next generation of products is referred to as precision navigation.

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).
