nowCOAST® offers new Gulf of Maine, Chesapeake Bay forecast services

Depiction of NOS Vv probability of occurrence forecast guidance for Chesapeake Bay on nowCOAST map viewer.

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 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 forecast data easier to display in marine navigation systems

By Neil Weston, Office of Coast Survey Technical Director

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.

NOAA Office of Coast Survey wraps up a busy 2017 hurricane season

The 2017 Atlantic hurricane season was powerful, with the strongest storms occurring consecutively from late August to early October. The sequential magnitude of four hurricanes in particular—Harvey, Irma, Maria, and Nate—made response efforts challenging for NOAA’s Office of Coast Survey. Coast Survey summarized this season’s response efforts along with the efforts of NOAA Ship Thomas Jefferson (operated by NOAA’s Office of Marine and Aviation Operations) in the following story map.

NOAA Ship Fairweather uses new technology to improve survey efficiency

Area surveyed by Fairweather May 30- June 10, 2017.
By ENS Peter Siegenthaler

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.

Storm surge model provides vital info for #Blizzard2016

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.

See the ESTOFS output here, or check nowCOAST for model output integrated with other data.
