NOAA's Precision Marine Navigation team is creating new online services to enable more efficient access to the NOAA data that powers private-sector marine navigation products. The goal is to foster innovation, improve navigation safety, aid in more efficient coastal route planning, and help mariners make informed decisions as they navigate our nation's waterways.

Currently, mariners may have to visit as many as eleven different websites to get the information they need to safely and efficiently navigate U.S. ports. NOAA’s Precision Marine Navigation team will make all of this critical information available at one convenient online location. This new website, which is currently under development, will provide mariners with two key services. One is a map viewer, which will allow users — mariners, recreational boaters, or any interested parties — to easily explore all available NOAA datasets from their computer or smartphone. The other component will feature robust technical documentation and application programming interfaces (APIs) for users who wish to ingest NOAA data into existing ship board navigation software.

The new online service will include a wide array of navigation data, such as Electronic Navigation Charts, high resolution bathymetry, water levels, surface currents, and marine weather hazards.

Combining NOAA navigational data and presenting it all in one online location will help improve decision-making throughout the maritime transportation industry. When the program becomes fully operational, all marine navigation data services that NOAA provides to mariners will be disseminated from a central location, allowing for systems to easily ingest and display the data for users to make decisions more efficiently. The many streams of data available to mariners become even more powerful when combined, potentially allowing mariners to optimize their routes in new ways to save time and fuel. NOAA is working to engage industry partners throughout the development of this new online service to ensure it meets the needs of the many users who rely on this data.

In the summer of 2020, NOAA released the first reformatted data service in support of Precision Marine Navigation through the NOAA Big Data Program. The first data service is for surface water current forecasts, which are extracted from the 15 regional NOS Operational Forecast Systems and from the Global Real-Time Ocean Forecast System for the Atlantic and Pacific Basins. The data is being automatically processed and uploaded to the NOAA Big Data Program cloud four times a day (every six hours) and is now available for companies to test using different types of navigation software.

Case Study: Port of Long Beach

The port of Long Beach in California acted as a case study for the Precision Marine Navigation Program. This port was an ideal candidate for this project for several reasons. First, it's one of the larger ports in the United States. Second, the port is exposed to the open ocean and is influenced by unique wave, swell, and water-level conditions that make navigation challenging. And third, ultra-large crude carriers entering Long Beach were vulnerable to potential groundings when waves arrived in long period swells.

By engaging a third party software manufacturer, which integrated NOAA’s data, navigation within the port was not only safer, but authorities were able to increase the draft for incoming ships from 65 feet to their goal of 69 feet. Each additional foot of draft allows carriage of 40,000 additional barrels of crude oil, and the reduced need for lightering saves shippers an estimated $10 million per year.

The Long Beach case study demonstrated the benefits of integrating NOAA’s datasets and provided the catalyst for more widespread implementation of the Precision Marine Navigation program.

Our nation’s ports are the lifelines of our economy. In 2016, foreign trades through U.S. ports were valued at $1.5 trillion—$475 billion exports and $1.0 trillion imports were moved by vessels. When goods travel through ports, it means they are traveling via ship.
