NOAA’s navigation assets complete primary post-Sandy assignments, remain available to assist   Leave a comment

NOAA continues to work in partnership with other federal, state, and local partners in response to the devastation of Hurricane Sandy. NOAA’s efforts are focused on navigation surveys to restore maritime commerce; aerial surveys to assist in those efforts and to aid on-the-ground responders from FEMA and local authorities; and in oil spill cleanup and damage assessment.  NOAA’s National Weather Service is also keeping authorities aware of changing weather conditions that could impact recovery and response efforts.

NOAA’s hydrographic survey vessels, including two three-person navigation response teams (NRTs) and the NOAA Ship Thomas Jefferson with her two survey launches, have completed surveys of the Port of New York and New Jersey. Working over the past five days, the high-tech vessels searched approximately 20 square nautical miles of shipping lanes, channels, and terminals to search for dangers to navigation.

Coast Survey navigation managers were embedded with the Coast Guard Maritime Transportation System Recovery Unit for the Port of NY/NJ, coordinating NOAA’s survey response. Lt. Brent Pounds, NOAA, explains ongoing survey operations to one of the port’s terminal operators during the height of operations.

Working with the U.S. Coast Guard (USCG) Maritime Transportation System Recovery Unit, NOAA surveyors provided near-real time updates on underwater object detection (including debris and shipping containers) that allowed the USCG Captain of the Port to make decisions on  port status. (Note: Follow the status of port conditions at U.S. Coast Guard Digital News.)

In addition to aiding in the gradual reopening of the New York City-area port to shipping, including special emergency deliveries of needed petroleum fuels products, NOAA navigation survey response teams also provided valuable data to allow for: the reopening of the port at Hampton Roads, Virginia, home of the largest naval base in the world and one of the nation’s leading ports for the shipping of coal; the reopening of the ports of Baltimore and Philadelphia; and the resumption of the ferry that connects Lewes, Del., and Cape May, N.J.— an important access route to bring aid to stricken New Jersey and Delaware shore communities.

While NOAA’s navigation assets have completed their primary assignments, they remain available to continue to assist the U.S. Coast Guard, as needed, and will be conducting additional surveys in smaller navigational areas of South Jersey and Delaware in coming days.

The NRTs’ work helps speed the re-opening of ports and waterways, allowing the flow of relief supplies, and enabling the resumption of ocean commerce — valued at more than $1 trillion annually to the nation’s economy — to resume.

NOAA hydrographers and survey technicians will continue to process the billions of points of data collected by the five NOAA vessels since Sandy response operations began on Oct. 30 at the Port of New York and New Jersey. While initial assessments are based off on-scene observations, additional image processing may reveal further details.

Once processed, Sandy response hydrographic data collected by all NOAA survey vessels in N.Y., N.J., Delaware Bay, and Chesapeake Bay will be available from the National Geophysical Data Center. This data is valuable for contemporary use—but also for reference if NOAA vessels need to re-survey the same areas in future years.

The National Ocean Service has more information on the status of post-Sandy operations for damage assessment, pollution response, and weather reporting.
