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.

Aids to navigation recovery operations with NOAA’s Navigation Response Branch and the U.S. Coast Guard

Flushing Bay Channel Lighted Buoy 3 was struck by a tug and barge in late July, and was reported sunk immediately following the strike. The buoy marks the entrance to a channel frequented by commercial barge traffic, specifically, loaded fuel barges bound for LaGuardia International Airport. The Navigation Response Branch (NRB) was called upon in early August to assist United States Coast Guard (USCG) Sector New York in locating the sunken buoy in Flushing Bay, New York.

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.

Nautical charts reflect alternate route along Gulf Intracoastal Waterway

Portion of Chandeleur Sound Gulf Intracoastal Waterway alternate route.

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.

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.

NOAA releases prototype surface current forecast data for industry testing

Prototype data for surface current forecasts in the International Hydrographic Organization (IHO) S-111 format is now available for testing through the NOAA Big Data Program. In June, NOAA announced that we were preparing surface current forecast data for dissemination trials. Now that these data are available, industry can integrate these prototype data into different types of navigation software systems such as portable pilot units and under keel clearance systems. By making these data more accessible, more machine-to-machine readable, and more integrated, NOAA aims to amplify the power of our navigation data for users across the maritime industry.
