NOAA Ship Thomas Jefferson tests drone use for shoreline mapping

By, Lt. j.g. Matt Sharr, NOAA, and Lt. Charles Wisotzkey, NOAA

NOAA’s Office of Coast Survey and the National Geodetic Survey (NGS) recently conducted operational tests of small unmanned aerial systems — or drones — on board NOAA Ship Thomas Jefferson in support of survey operations conducted along the south coast of Puerto Rico. The tests show the potential of imagery from low-cost off-the-shelf drones to meet NOAA survey specifications for near-shore and shoreline feature mapping. This could replace traditional shoreline verification and mapping techniques used by NOAA hydrographic survey field units. Potential benefits of using drones for shoreline mapping include: improved data collection efficiency compared to data collection from small skiffs; more accurate feature investigation than traditional techniques; and, most importantly, removal of personnel from potentially dangerous situations (i.e. survey in close proximity to features being mapped).

NOAA makes it easier to submit a comment or report a nautical chart error

On November 16, 2018, NOAA released ASSIST, a new system for submitting questions and reporting nautical chart errors to NOAA’s Office of Coast Survey. ASSIST has a mobile-friendly design and improved user interface that allows customers to access the system conveniently from any device. This new tool replaces Coast Survey’s Inquiry and Discrepancy Management System (IDMS), a database that collected nearly 20,000 comments, inquiries, and discrepancy reports since 2008. ASSIST is available from: https://www.nauticalcharts.noaa.gov/customer-service/assist/ Continue reading “NOAA makes it easier to submit a comment or report a nautical chart error”

NOAA supports Coast Guard and Marine Corps resume training following Hurricane Florence

By, Lt. j.g. Patrick Debroisse

Hurricane Florence came ashore along the North Carolina coast on September 14, 2018, bringing Category 1 force winds and substantial amounts of rain and storm surge. One of the areas affected by the storm was the United States Marine Corps’ Camp Lejeune, which suffered infrastructure and waterway damage. Camp Lejeune is home to the Second Marine Division, multiple training commands, and the U.S. Coast Guard’s Special Missions Training Center (SMTC). The Coast Guard uses the waters around the camp for small boat tactics training. Continue reading “NOAA supports Coast Guard and Marine Corps resume training following Hurricane Florence”

Coast Survey spotlight: Meet Tsering Chuki


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.


Tsering Chuki, financial management specialist

I find it rewarding when all our procurement actions are awarded on time and contracts are fully funded.  By having fully funded contracts (software licenses, hardware, or manpower) our division is able to fulfill all the tasks skillfully and timely.”

NOAA preserves history of Washington, DC, with reproduced L’Enfant maps

This copper plate, named No. 3043 PRICE 45 CENTS, is one of the 3000 series of special products produced by Coast Survey’s predecessor, the Coast and Geodetic Survey. The Coast and Geodetic Survey primarily made nautical charts, but a number of maps in the 3000 series were instead maps of some thematic factor of interest (i.e., the Slaver Map, No. 3033; Glacier Bay, Alaska, No. 3095).

By Capt. Albert “Skip” Theberge (NOAA, ret.)

Research conducted by the NOAA Central Library uncovered a little known fact that NOAA Coast Survey’s skill in reproducing maps helped ensure that early maps of Washington, DC, and an interesting piece of history, weren’t lost. Coast Survey reproduced three historically significant maps from a copper plate engraving of Washington, DC, as surveyed by Pierre L’Enfant and Andrew Ellicott.

NOAA Ship Rainier spent September completing a multi-leg, joint collaboration project investigating deep offshore areas of the southern California coast. The U.S. Geological Survey (USGS) and Bureau of Ocean Energy Management (BOEM) partnered with NOAA to support a month-long mission to collect geophysical data along the outer continental shelf of California where the area in question features a number of different geologic structures and processes.

NOAA Ship Thomas Jefferson successfully tests new wireless system that aids remote vessel operation

By Lt. Charles Wisotzkey, NOAA

NOAA Ship Thomas Jefferson successfully tested a new wireless networking system while working in the Approaches to Houston/Galveston and around Puerto Rico during the 2018 field season. This new system connects the ship and its two hydrographic survey launches, providing a level of wireless connectivity previously unobtainable with traditional wireless communications systems. NOAA anticipates this will increase unmanned system productivity while conducting hydrographic surveys.

NOAA detects navigation hazards following Hurricane Michael

After quickly gaining the strength of a Category 4 storm, Hurricane Michael reached the panhandle of Florida on Wednesday, October 10. With maximum sustained winds of 155 mph and storm surge reaching 15 feet, this storm wiped out coastal communities and closed ports to all traffic in the area. Dangerous winds and storm surge can shift sands and pull large objects beneath the waves, creating hazards to navigation. Before ports can reopen and safely resume vessel traffic, the U.S. Coast Guard must be aware of any underwater dangers so they can either be properly charted or removed.
