NOAA releases 2023 hydrographic survey season plans

An image showing all NOAA hydrographic survey vessels.

NOAA hydrographic survey ships, navigation response teams, and contractors are preparing for the 2023 hydrographic survey season. The ships and survey vessels collect bathymetric data (i.e. map the seafloor) to support nautical charting, modeling, and research, but also collect other environmental data to support a variety of ecosystem sciences. NOAA considers hydrographic survey requests from stakeholders such as marine pilots, local port authorities, the Coast Guard, and the boating community, and also considers other hydrographic and NOAA science priorities in determining where to survey and when.

On February 14, 2023, NOAA’s Office of Coast Survey released NOAA Custom Chart version 2.0, a dynamic map application, which enables users to create their own paper and PDF nautical charts derived from the official NOAA electronic navigational chart (NOAA ENC®), NOAA’s premier nautical chart product.

Conducting survey operations with Coast Survey’s navigation response teams

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.

Have it your way – creating customized nautical charts using the latest data

Nautical charts have always contained a great amount of information – even more so with electronic navigational charts. This information is constantly being updated, necessitating the need to keep your nautical chart suite as current as possible. The Office of Coast Survey’s online NOAA Custom Chart application enables users to create nautical charts directly from the latest official NOAA electronic navigational chart (NOAA ENC®) data. Users now have the ability to create their own nautical charts using individually set parameters, and then save this custom nautical chart as a file that can be viewed or printed.

NOAA ocean mapping and reef surveys in the Mariana Islands

On March 26, NOAA Ship Rainier set sail from Honolulu, Hawaii on a 3,307-nautical mile expedition to the Western Pacific. Originally planned for 2020, this will be the ship’s first multidisciplinary expedition to Guam and the Commonwealth of the Northern Mariana Islands. This collaborative mission between NOAA’s National Ocean Service and National Marine Fisheries Service will deliver high‐quality data, data products, and tools to the region including a seamless map linking hilltops to underwater depths and integrated data on the surrounding coral reef ecosystems. These data can provide information for countless users to make critical management decisions within disciplines such as habitat management and restoration, tsunami modeling, monitoring, and marine resource management.

Coast Survey launches NOAA Chart Display Service

This is a graphic showing an electronic navigational chart depicting the entrance to the Columbia River and Astoria, Oregon. Graphical information on the chart is rendered by the new NOAA Chart Display Service and shows traditional paper chart symbols.

The new NOAA Chart Display Service (NCDS) renders NOAA electronic navigational chart (NOAA ENC®) data with “traditional paper chart” symbology in online and offline applications for which a basemap of nautical chart data is desired, including GIS, web-based, and mobile mapping applications. The new service uses symbols, labels, and color schemes familiar to those who have used NOAA paper nautical charts or the NOAA Custom Chart application. NCDS is available as Esri REST Map Service, OGC Web Map Service (WMS), and MBTiles formats.

NOAA releases 2022 hydrographic survey season plans

NOAA Ship Fairweather in College Fiord, Alaska

NOAA hydrographic survey ships and contractors are preparing for the 2022 hydrographic survey season in U.S. coastal waters and beyond. The ships collect bathymetric data (i.e. map the seafloor) to support nautical charting, modeling, and research, but also collect other environmental data to support a variety of ecosystem sciences. NOAA considers hydrographic survey requests from stakeholders such as marine pilots, local port authorities, the Coast Guard, and the boating community, and also considers other hydrographic and NOAA science priorities in determining where to survey and when.

The nautical chart update process – build it and we will chart it

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.

Collecting aerial images on the Chesapeake’s Western Shore

By Tom Loeper

Early in the morning of June 15, John Doroba and Tom Loeper met with Anne Arundel Park Ranger Adam Smith to collect aerial oblique images of several rivers on the Western Shore of the Chesapeake Bay. These images will be used to update existing content in the United States Coast Pilot 3, Atlantic Coast: Sandy Hook, New Jersey to Cape Henry, Virginia. In addition to acquiring images, experience gained during the field exercise will be used to update aerial photography specifications in the Coast Pilot manual.

Coast Survey to shut down the Raster Navigational Chart Tile Service and other related services

NOAA will shut down its Raster Navigational Chart (RNC) Tile Service and the online RNC Viewer on October 1, 2021. The NOAA Seamless Raster Navigational Chart Services will be shut down on January 1, 2022. This is part of a larger NOAA program to end production and maintenance of all NOAA traditional paper and raster nautical charts that was announced in the Federal Register in November 2019.
