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.

Sheets of ice stretch for miles and miles. Mountains and peaks reach with jagged arms straight for the heavens. Snowmounds inoffensively deafening visitors in the winter months with a quiet like no other. Glacier walls and their child icebergs bobbing in the deep, cold water at every turn. Wildlife of the sky and sea of every shape and size, from Tufted Puffins and Kittlitz’s Murrelets to harbor seals and orcas – this is Prince William Sound.

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.

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.

The Precision Marine Navigation (PMN) program has completed the first update of its prototype navigation data service – the PMN data processing and dissemination system and PMN Data Gateway viewer. The data processing and dissemination system provides surface current forecast guidance from NOAA’s forecast systems, in a prototype marine navigation data format. The viewer allows users to visualize the predictions and discover where they are. Both the system and the viewer were updated to include data from the recently upgraded Northern Gulf of Mexico Operational Forecast System (NGOFS2).

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.

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.

This week NOAA’s Office of Coast Survey concluded its hydrographic survey response following Hurricane Delta. At the immediate request of the U.S. Army Corps of Engineers (USACE), NOAA’s navigation response teams (NRTs) and NOAA Ship Thomas Jefferson surveyed areas within the Gulf Intracoastal Waterway (GIWW), Calcasieu Ship Channel, and the entrance to the channel. With lessons learned from the response to Hurricane Laura — the first major hurricane of the 2020 season and the first hurricane response during a pandemic — the teams and Thomas Jefferson successfully collected, processed, and delivered data to the USACE, identifying significant hazards to navigation and helping to ensure the timely reopening of waterways.

“As a cartographer, I consider it a success if the updates to a chart are accurate and justified, reviewed by another with little or no revisions, and is deemed useful and safe for the public.“
In anticipation of the temporary closure of the Gulf Intracoastal Waterway (GIWW)’s Inner Harbor Canal Lock, the Office of Coast Survey released three updated NOAA electronic navigational charts (NOAA ENC®) reflecting the Chandeleur Sound Alternate Route and the addition of 97 Aids to Navigation (ATON). The updated charts include US5LA24M, US4LA34M, and US4MS12M and can be viewed in NOAA’s ENC Viewer or downloaded from NOAA’s Chart Locator.
