NOAA’s Office of Coast Survey released a new electronic navigation chart (NOAA ENC®) of Haverhill, Massachusetts, and the Merrimack River (US5MA1AM). With this new chart, recreational boaters now can safely navigate the Merrimack River from the entrance at Newburyport all the way to Haverhill, just in time for boating season.
How many geospatial products can be developed by one seafloor mapping project? As a phased-in project for Long Island Sound shows, a strong collaboration among diverse groups of researchers and technology developers can integrate temporal and geospatial data sources to produce dozens of products. In addition to updating NOAA’s nautical charts, ongoing collaborations in Long Island Sound will create products that depict physical, geological, ecological, geomorphological, and biological conditions and processes – all to balance the development of new ocean uses while protecting and restoring essential habitats.
Coast Survey navigation response teams know the meaning of “rapid” in Rapid Maritime Response, as their ongoing response following Hurricane Isaac demonstrates.
As we explained in yesterday’s post (NOAA looks for dangers to navigation at Port Fourchon), getting a navigation response team (NRT) into the water at the port, to search for underwater debris and shoaling ‒ ASAP ‒ was Coast Survey’s highest priority. It was also a priority for port authorities, who know more than anyone how important it is to resume maritime operations quickly at “The Gulf’s Energy Connection.”
A rapid maritime response by NOAA’s Office of Coast Survey will likely pay dividends to the U.S. economy, as a high-tech survey team today began surveying the channels of Port Fourchon, the “Gulf’s Energy Connection,” to search for dangers to navigation caused by Hurricane Isaac.
“Time literally means money for U.S. consumers when it comes to navigation through many of the Gulf of Mexico ports,” said Rear Adm. Gerd Glang, Office of Coast Survey director. “In this case, when a port can’t service offshore oil rigs, everyone — and most especially consumers — gets hit in the wallet.”
Coast Survey’s Rapid Maritime Response assets for Hurricane Isaac are now in place, and are ready to move in when the storm moves on.
The teams will search for underwater debris and other dangers to navigation in port areas, to speed the resumption of shipping in areas impacted by the storm. A rapid response — that gives Coast Guard officials vital information on the condition of ship channels — reduces economic losses in maritime trade, reduces potential disruptions in energy supplies when ports are serving energy providers and oil rigs, and keeps mariners safe. (For more, see Coast Survey Prepares Rapid Maritime Response for Tropical Storm Isaac.)
As NOAA’s National Weather Service adjusts the track of Tropical Storm Isaac, so Coast Survey adjusts pre-response planning and deployment. (BTW, the New Orleans/Baton Rouge NWS Tropical Weather Briefing is a great resource for maritime observations, as is nowCOAST.) Based on updates in the hurricane models, and after multiple briefings with Coast Guard officials, Coast Survey is moving to pre-position two of the navigation response teams closer to the expected impact areas. (See response asset graphic, below.)
Major ports along in Alabama, Mississippi, and Louisiana will likely be closed later today, if they aren’t already. With over $153 billion in ocean-going trade through New Orleans annually, and another $31 billion a year in and out of Mobile, it is essential to get shipping channels cleared for the resumption of traffic as soon as possible after a storm. Just as important, the Gulf produces 23 percent of total U.S. crude oil production and 7 percent of natural gas production, according to the U.S. Energy Information Administration. The resumption of operations at ports serving the energy industry is essential to keeping supplies flowing.
1200 hours, August 12, 2012: 70°38.7’N 162°06.6’W, approximately 22 miles north of Icy Cape, Alaska’s North Slope
In 1963, the town of Point Hope (68° 21’N 166°46’W) – a small, ancient, and archeologically-significant Inupiaq community on Alaska’s North Slope that remains at present a largely native village – narrowly avoided the creation of an artificial harbor by underwater hydrogen bombs. Part of “Project Plowshare,” the planned creation of a deepwater harbor by thermonuclear power was intended to demonstrate the peaceful use of nuclear power for construction purposes. It was opposed by Native American communities, scientists in the state, and the Episcopalian church across the United States. The protest has been credited as one of the first government projects successfully challenged on the grounds of its potential environmental impact.
Last week, the navigation team worked with federal and state partners who help us understand the rich history – and the secrets of human sorrows – lying on the seafloor. In collaboration with NOAA’s Flower Garden Banks National Marine Sanctuary and the Texas Historical Commission’s Marine Archeology Division, the navigation response team — with the State Marine Archeologist onboard — re-mapped the location of two historically significant wrecks. (Some of the data was collected under an antiquities permit, as Texas requires for investigating historic shipwrecks in state waters.)
