The National Bathymetric Source (NBS) project creates and maintains high-resolution bathymetry composed of the best available data. This project enables the creation of next-generation nautical charts while also providing support for modeling, industry, science, regulation, and public curiosity.

During the month of October, NOAA Ship Thomas Jefferson integrated and operated a DriX, an Unmanned Surface Vessel (USV) created by the French technology company iXblue. The primary goal of the project was to test iXblue’s unique deployment and recovery solution specifically designed for Thomas Jefferson’s on board survey launch davit. Survey launches are limited to daylight operations and deployment and recovery are the most challenging operations the ship undertakes. Utilizing a DriX for continuous survey operations without having to recover and/or service it for up to four days straight would significantly increase the ship’s efficiency.

UPDATE: The Nav-cast scheduled for 9/26 at 1 p.m. (EDT) is cancelled and will be rescheduled at a later date. We apologize for the inconvenience.
Join us for our next NOAA Nav-cast, a quarterly webinar series that highlights the tools and trends of NOAA navigation services.
NOAA’s nowCOAST: A one-stop-shop for coastal conditions before you head out on the water
NOAA’s nowCOAST (nowcoast.noaa.gov) — a free online interactive map viewer —provides situational awareness on present and future weather and oceanographic conditions for mariners and other coastal users by integrating data from across NOAA and regional observing systems. Users can assess present conditions by creating maps of the latest in-situ weather/marine weather observations, weather radar mosaics, cloud images from GOES weather satellites, and surface wind and sea-surface temperature analyses for the last few hours. Users can also obtain maps of critical weather/marine weather advisories, watches, and warnings, weather forecasts, tropical cyclone track and intensity forecasts, and forecast guidance of water levels, water temperature, salinity, and currents from NOAA oceanographic forecast models. Users can display these maps using the nowCOAST map viewer or by connecting to its map services. nowCOAST operates in a high-availability hosting facility and is monitored 24 x 7.

NOAA Ship Rainier field tested a new hydrographic survey platform this season. Last winter, one of the ship’s hydrographic survey launches was converted into a semi-autonomous vessel, allowing it to be operated remotely. Hydrographic surveying is, by nature, dangerous. Autonomous systems have the potential to augment traditional surveying methods, improving efficiency and decreasing (or eliminating) risk to the surveyors themselves. As such, this technology is an exciting step toward fully-autonomous hydrographic survey systems.

NOAA’s Office of Coast Survey, the University of Southern Mississippi (USM), and Saildrone accomplished a key milestone in the research and testing of unmanned technology that can lead to enhanced seafloor mapping capabilities with the launch of the first Saildrone — a wind-driven and solar-powered unmanned surface vehicle (USV) — equipped with multibeam echo sounder technology in the Gulf of Mexico. NOAA anticipates the success of this mission and technical achievement will lead to mapping projects in the Arctic.

Hydrographic surveying continually evolves to improve safety, efficiency, and accuracy in data collection. From using side scan sonar equipment during hydrographic survey response efforts following air disasters in the late 1990s, to recent hurricane response efforts to re-open ports to maritime commerce, our science always strives to be cutting edge.

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 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 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.

A team composed of research engineers and a graduate student from the University of New Hampshire Center for Coastal and Ocean Mapping/Joint Hydrographic Center (UNH CCOM/JHC) and personnel from NOAA’s Office of Coast Survey are aboard the NOAA Ship Fairweather to test UNH’s BEN (Bathymetric Explorer and Navigator) unmanned surface vehicle (USV). On Saturday, July 28, the Fairweather made the first successful launch of a USV for an operational hydrographic survey from a NOAA vessel in the Arctic. The team conducted four additional deployments, including an extended overnight survey made in coordination with the ship.
