The Pacific Ocean is the largest and deepest of Earth’s oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean in the south and is bound by the continents of Asia and Australia in the west and the Americas in the east. Most of the U.S. Pacific territories are located in the northern half of the Pacific Ocean and are among the Pacific Islands that are highly exposed to natural disasters. As part of NOAA’s coastal resilience efforts, the National Ocean Service (NOS) is developing better tools to define changes in water level related to tropical cyclones and other weather related conditions. This work is part of the global effort to develop disaster risk assessment tools and practical technical applications to reduce and mitigate coastal countries’ vulnerability to natural disasters.
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.
This week, as part of the 40th anniversary of the XIII Olympic Winter Games in 1980, the Lake Placid Olympic Museum launched the exhibit, Foretelling the Future – The National Weather Service at the 1980 Olympic Winter Games. These Olympic Games stand out in our collective memory as the venue for the “miracle on ice,” when the U.S. hockey team beat the 4-time Olympic champions, the Soviet Union. Little do most people know, however, another kind of team was pulling off a small miracle of their own at these games.
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.Continue reading “nowCOAST® offers new Gulf of Maine, Chesapeake Bay forecast services”

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 recently hosted its fourth NOAA Navigation Industry Day at the Annapolis Yacht Club adjacent to this year’s Annapolis Boat Show. This annual event welcomed maritime application and navigation system developers interested in learning about the latest freely-available navigation-related data streams, models, and products that NOAA offers.

Have you ever been on the water when weather and sea conditions suddenly change? As mariners can attest, decisions need to be made quickly. Many rely on NOAA operational forecast system (OFS) data—a national network of nowcast and forecast models—to make decisions about their situation on the water. NOAA OFS are available to the mariner as data streams through a variety of websites, including nowCOAST™. However, only recently has OFS data been viewable on marine navigation systems, making it even more convenient for those needing to make critical decisions on the water.
Following the scheduled winter repair period, Fairweather is kicking off the 2017 field season in Tlevak Strait; the waterway between Dall Island and Prince of Wales Island in Southeast Alaska. This area was last surveyed between 1900 and 1939, and the lead-lines used at the time to determine depths were susceptible to omission of rocks and other features in an area. Using the latest innovations in hydrographic technology, Fairweather will be resurveying these areas with complete coverage multibeam echo sounder bathymetry. This allows Fairweather to identify any rocks or shoal features missed in prior surveys, increasing the safety for local communities, whose economies and livelihoods are dependent on maritime transportation of goods. Continue reading “NOAA Ship Fairweather uses new technology to improve survey efficiency”
NOAA runs operational forecast modeling systems that provide users with forecast guidance of water levels, currents, and water temperatures for the next 60 hours. The Extratropical Surge and Tide Operational Forecast System (ESTOFS), a storm surge model developed by Coast Survey in 2012, is a vital source of information for forecasting coastal flood events during this weekend’s blizzard.
