NOAA’s nowCOAST®, a GIS-based online web mapping service that provides frequently updated weather and ocean observations, analyses, imagery, and ocean model forecast guidance, along with weather watches and warnings and forecasts, now provides maps of oceanographic forecast guidance from the National Ocean Service (NOS) 3-D operational forecast modeling system for the Gulf of Maine (GoMOFS) and NOS forecast guidance of the marine pathogen, Vibrio Vulnificus (Vv), for the Chesapeake Bay via two new map services and map viewer.

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).

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”

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.

Mount Fairweather stands tall above Glacier Bay National Park and Preserve, dominating the skyline for miles around (when weather permits visibility). Only about 12 miles inshore from the Gulf of Alaska and soaring to 15,325 feet, it is one of the highest coastal peaks in the world.
NOAA kicked off its spring season for post-Sandy hydrographic work on April 11, as a navigation response team — equipped with high-tech surveying equipment — began a search for underwater storm debris and mapped the depths surrounding Liberty Island and Ellis Island. Navigation Response Team 5 wrapped up their project today, after surveying over 110 linear nautical miles. They surveyed for 119 hours, collecting over 578 million depth measurements.
In addition to surveying around Liberty Island and Ellis Island, Coast Survey’s NRT5 surveyed adjacent areas to acquire data for updates to NOAA’s nautical charts. This is the “rainbow” coverage map that shows the surveyed area. (The colors indicate depth.)
Countries issue advance notice for changes in electronic charts
To comply with internationally agreed practices, Canada and the U.S. have been eliminating overlapping coverage of electronic navigational charts (ENCs). New changes will soon take effect in the Great Lakes. Under the new ENC coverage scheme, each country is changing their areas of coverage so that only one country’s ENC is available for any given area at a particular scale.
These changes come into effect 0000 Coordinated Universal Time (UTC), on 22 February, 2013.
NOAA’s newest survey ship, the Ferdinand R. Hassler, began survey operations today in support of the U.S. Coast Guard efforts to re-open the Port of Virginia. Hassler was in port at NOAA’s Marine Operations Center – Atlantic in Norfolk, Virginia, for maintenance when Hurricane Sandy affected the area. The ship’s crew spent Monday completing the work and system tests necessary to get underway once the storm passed, and has now been returned to limited operational status.
As conditions go downhill, NOAA is deploying personnel and hydrographic survey assets to help speed the resumption of shipping after SANDY clears out.
Coast Survey has deployed navigation managers from outside Hurricane Sandy’s areas of impact, supplemented with headquarters personnel, moving them to areas expected to be hit hard. Navigation managers are now at U.S. Coast Guard Incident Command Centers for New York – New Jersey and for Delaware Bay. We are also working with Coast Guard Captains of the Port for Virginia, Baltimore, and New England. NOAA’s navigation managers are working with the Coast Guard and the Army Corps of Engineers to coordinate deployment of NOAA’s navigation response teams (NRT) for rapid maritime response. They are also identifying vessels of opportunity, for potential use with Coast Survey’s mobile survey team (MIST).
