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.Continue reading “Have it your way – creating customized nautical charts using the latest data”
In 2022, NOAA and NOAA contractors will survey U.S. coastal waters and beyond, including multiple missions in the Great Lakes. As the volume, value and size of marine vessels in U.S. waters continues to grow, it is essential that NOAA increase the accuracy and frequency of surveys. A great amount of data on nautical charts of the Great Lakes is more than 50 years old, and only about 5 to 15 percent of the Great Lakes are mapped to modern standards using remote sensing methods such as light detection and ranging and sound navigation and ranging.Continue reading “NOAA focuses on the Great Lakes for the 2022 field season”

In 1959, following the International Geophysical Year of 1957-58, scientists from twelve nations conducting active research in Antarctica came together and signed the Antarctic Treaty. In the years following, 42 additional countries acceded to the treaty. The treaty preserves the entire continent and surrounding waters solely for purposes of peaceful scientific collaboration and bans resource extraction and military activity. McMurdo Station on Ross Island, operated by the United States through the United States Antarctic Program, a branch of the National Science Foundation (NSF), has emerged as the largest year-round station and primary logistics hub for the region. The first U.S. Operation Deep Freeze happened prior to and in support of the International Geophysical Year of 1957-58. Since then, Operation Deep Freeze has continued annually and has become the name for supply sealift missions to McMurdo, delivering fuel, food, and supplies to scientists in Antarctica.Continue reading “Coast Survey’s mobile integrated survey team goes to Antarctica”
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.

Throughout the spring and summer of 2021, NOAA Ship Rainier surveyed numerous bays and inlets of Alaska’s Glacier Bay National Park and Preserve. As one of the largest national wilderness systems and a United Nations designated World Heritage Site, Glacier Bay National Park includes over 2.7 million acres of marine, terrestrial, and freshwater ecosystems. This dynamic landscape is a living example of a never-ending cycle of geological and ecological change and adaptation. With up to 20-foot tide ranges, seasonal migrations of humpback whales and salmon, and glaciers in flux, the resilient ecosystem attracts millions of visitors each year. This year, Rainier surveyed the Beardslee Islands, Geikie Inlet, Berg Bay, Muir Inlet, Bartlett Cove, Pleasant Island, Taylor Bay, and Dundas Bay. Each survey area revealing several changes in seafloor bathymetry and bottom type. High-resolution seafloor bathymetry will be used to update nautical charts for safe navigation and serve as baseline data to support further research of this culturally and ecologically significant marine environment.Continue reading “Deep fiords and hydrographic history in Glacier Bay National Park”

University of New Hampshire’s Center for Coastal and Ocean Mapping and NOAA are giving undergraduate students the opportunity to participate in seafloor mapping and associated exercises aboard a survey vessel this summer. Natalie Cook, a junior in the Ocean Engineering program, is spending eight weeks aboard NOAA Ship Thomas Jefferson, a 208-foot hydrographic survey vessel, experiencing all aspects of hydrography. Natalie is standing survey watch, processing data, working on survey launches, and serving as an active member of the hydrographic survey team.

After a busy winter in port, NOAA Ship Thomas Jefferson started the 2021 field season in familiar waters, returning to survey the approaches of the Chesapeake Bay. Towards the end of the 2020 field season, the crew of the Thomas Jefferson spent their first 45-day “COVID-19 bubble” on this project. A bubble is formed when crew quarantine and test for COVID-19 prior to crewing the ship, staying isolated onboard until the end of the 45-day period. This protocol is part of the Office of Marine and Aviation Operations (OMAO) COVID-19 mitigation strategy. In April and May of 2021 Thomas Jefferson spent an additional 28 days surveying an area approximately 40 nautical miles east of Virginia Beach, Virginia.Continue reading “Surveying the approaches to the Chesapeake Bay”
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.Continue reading “Coast Survey to shut down the Raster Navigational Chart Tile Service and other related services”

Last Thanksgiving, the crew of NOAA Ship Fairweather were busy surveying in one of the country’s busiest waterways. A global maritime entryway to the Pacific Northwest, the Strait of Juan de Fuca sees over 8,000 transits of deep-draft container ships, cargo and chemical carriers, oil tankers, and barges coming to and from Puget Sound and Canada. In addition to industrial shipping, the Strait of Juan de Fuca also supports over 200,000 transits of recreational vessels and Washington State Ferries. Located north of the Olympic Peninsula, the Strait forms the northwestern most border between the contiguous U.S. and Canada. On the American side, the region is home to eight million people including 50 First Nation communities with centuries old cultural ties to traditional fishing.Continue reading “Surveying in the Strait of Juan de Fuca during a global pandemic”
On April 1, 2021, NOAA’s Office of Coast Survey released NOAA Custom Chart version 1.0, a dynamic map tool 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.Continue reading “NOAA Custom Chart version 1.0 released to the public”
