Surveying the approaches to the Chesapeake Bay

Thomas Jefferson at anchor in Lynnhaven anchorage

By Ensign Gabriella McGann

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.

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.

NOAA’s Precision Marine Navigation data service receives first major update

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).

Surveying in the Strait of Juan de Fuca during a global pandemic

By Ensign Jessie Spruill and Hydrographic Senior Survey Technician Simon Swart, NOAA Ship Fairweather

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.

NOAA Custom Chart version 1.0 released to the public

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.

NOAA concludes hydrographic survey response following Hurricane Delta

NOAA Ship Thomas Jefferson Launch 2904 surveying the Bar Channel, Calcasieu, Louisiana Approach.

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.

Coast Survey Spotlight: Meet James Moy

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.

James Moy, Cartographer

“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.“

NOAA’s Office of Coast Survey awarded a 5-year cooperative agreement to the University of New Hampshire for the continuation of the Joint Hydrographic Center. The Joint Hydrographic Center is a NOAA/University research and education partnership aimed at maintaining a world-leading center of excellence in hydrography and ocean mapping. The new award, which will begin in January 2021, will build on the work of the Center since its founding in 1999.

NOAA Coast Survey’s new strategy supports charting mandates and broader seafloor mapping

This week, NOAA’s Office of Coast Survey released the Mapping U.S. Marine and Great Lakes Waters: Office of Coast Survey Contributions to a National Ocean Mapping Strategy. This report is part of NOAA’s ongoing commitment to meet core surveying and nautical charting mandates while supporting broader needs to fill gaps in seafloor mapping and environmental sciences.
