NOAA Ship Rainier is due to arrive at its homeport in Newport, Ore., on November 1, completing the ship’s 2012 hydrographic survey season. (Watch Rainier’s progress on NOAA’s Ship Tracker.) This survey season, Rainier departed Newport on May 17 and spent her summer mapping 604 square nautical miles of the ocean floor in Alaska, stretching from Kodiak to the Shumagin Islands, along the Alaskan archipelago.
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).
As Hurricane SANDY heads north along the Atlantic coast, NOAA’s Office of Coast Survey is deep into preparations for maritime rapid response. Two objectives stand out: move navigation response personnel and assets into position to move quickly once SANDY moves out; and batten down survey vessels, to protect them from storm damage.
Coast Survey regularly responds to requests for quick navigation surveys after storms and other damaging events, pulling vessels from their normal survey schedules and deploying them to ports that need hydrographic surveys before they can resume full-fledged shipping.
Today’s post is written by a guest blogger, Dr. Bob McConnaughey. Bob is the FISHPAC project chief scientist, with NOAA’s Alaska Fisheries Science Center.
Fishery biologists and hydrographers in NOAA are working together to solve two very important problems in the eastern Bering Sea. This area is one of the richest and most productive fishing grounds in the world. Careful management of harvest levels is one part of the effort to sustain these populations into the future. However, it is also important to understand the habitat requirements of the managed species so we can protect the foundation for these high levels of production.
To this end, a team of scientists at the Alaska Fisheries Science Center (AFSC) is developing mathematical models to explain the distribution and abundance of groundfish, such as pollock and cod, and benthic invertebrates, such as red king crab, in order to determine their essential habitats. The research team gathers new environmental data at locations where other AFSC scientists sample fish populations during annual bottom-trawl surveys. In many cases, existing habitat information is very limited, but studies will identify useful variables and the best tools for measuring them over large areas of the continental shelf.

The U.S. and Canada have been surveying in the northern Atlantic Ocean this summer, gathering data to support both countries’ territorial claims under the United Nations Convention on the Law of the Sea (UNCLOS). The survey project started on August 15, and the ship is scheduled to return to Woods Hole, Massachusetts, on September 10.
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.

This week the NOAA Ship Fairweather is completing her 30-day hydrographic reconnaissance survey in the Arctic. The crew’s personal observations during this successful cruise brings home the importance of measuring ocean depths and updating nautical charts with precise and accurate modern data. Ensign Owen provides Fairweather’s last blog post for this project. – DF
