New NOAA website provides marine navigation resources in a central location

Commercial vessels navigating in the Port of Los Angeles-Long Beach

A recently launched website from NOAA’s Precision Marine Navigation (PMN) program will improve the use and accessibility of NOAA’s marine navigation products and services. The website, Marine Navigation, includes links and short descriptions to NOAA’s various navigation resources, providing a one-stop shop that mariners can visit to get the data they need. Designed for shipping professionals and recreational boaters alike, the PMN program hopes the website will become a valuable tool to support all mariners in their navigation planning and decision making processes.

NOAA Ship Thomas Jefferson returns to survey approaches to Chesapeake Bay during the 2020 field season

NOAA Ship Thomas Jefferson

By Hydrographic Assistant Survey Technician Sophia Tigges

For the first portion of the 2020 field season, NOAA Ship Thomas Jefferson surveyed approaches to Chesapeake Bay. Thomas Jefferson’s 2020 field season consisted of two 45-day “bubble” periods. A “bubble period” is the time a ship closes to personnel transfer while they shelter in place for seven days and undergo COVID-19 testing per NOAA’s Office of Marine and Aviation Operation’s COVID-19 protocol to mitigate exposure. The ship spent the entire first bubble working off the coast of North Carolina and Virginia for this project. These surveys served as a continuation of the ship’s work in the area in the 2019 season.  (To learn more about Thomas Jefferson’s work in this area last year, read the 2019 post titled, “NOAA Ship Thomas Jefferson tests innovative DriX unmanned surface vehicle.”

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.

NOAA navigation response teams complete hydrographic surveys following Hurricane Laura

Lt. John Kidd operates the NRT-Stennis vessel in Devil's Elbow.

Hurricane Laura, the first major hurricane of the 2020 Atlantic Hurricane Season, made landfall over Louisiana in the early morning hours of Thursday, August 27. As a Category 4 storm and with maximum sustained winds reaching 150 miles per hour, it caused significant damage along the Gulf coasts of Louisiana and southeastern Texas. For NOAA’s Office of Coast Survey –  whose job it is to identify dangers to navigation and help speed the reopening of ports and waterways following severe storms – this marked the first hydrographic survey response effort of the hurricane season.

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.

High-definition charts advance precision marine navigation

Vessel entering the port of Long Beach, California.

By Craig Winn, HD charting portfolio manager

For large vessels entering port where there is next to zero margin for error, pilots and shipmasters are looking for the highest resolution data available to help them navigate these tight spaces safely and efficiently. NOAA’s Office of Coast Survey recently constructed and released 16 high-definition (HD), band 6 (or berthing scale) electronic navigational charts for Los Angeles/Long Beach Harbor, providing mariners with the best charts available to do their job.

A message to hydrographers: Your time is now

A global view of mapped and unmapped portions of the world ocean.

By Rear Adm. Shep Smith, Director of NOAA’s Office of Coast Survey

There has never been a better time to be a hydrographer. Our skills, data, and technology are in high demand globally, driven by an increased emphasis both on supporting the blue economy and of protecting the ocean upon which all life on earth depends. The UN declared this decade the “Decade of Ocean Science for Sustainable Development,” and that vision specifically calls out the need to map the world’s oceans. The Nippon Foundation has breathed new energy into the century-long project to create a General Bathymetric Chart of the Oceans (GEBCO) with a supporting campaign called Seabed 2030. Hydrography is now invaluable for habitat mapping, for mineral and energy exploration, for offshore wind development, and for ocean modeling supporting everything from predicting local harmful algal blooms to understanding the earth system itself at a global scale.

NOAA joins federal and state partners in signing MOU on emergency maritime response in Hawaii

Coast Survey’s hydrographic survey experts along with the Office of National Marine Sanctuary staff are ready to survey Honolulu Channel following Hurricane Lane.

NOAA’s Office of Coast Survey, United States Coast Guard (USCG) Sector Honolulu, State of Hawaii Department of Transportation and United States Army Corps of Engineers (USACE) Honolulu Division established a memorandum of understanding (MOU) outlining each signatory’s area of responsibility in the event of a disaster in the Hawaii region. The intent of the MOU is to improve the efficiency and effectiveness of response efforts and speed the reopening of the ports and waterways following an emergency.
