Forecast System Guides Naval Ship Through Icy Waters

May 4, 2020
Research in the polar ocean regions is made extremely difficult by constantly moving and shifting ice masses in the Arctic and Antarctic Oceans.

Research in Arctic and Antarctic waters typically require navigating through ice-filled seas. But the U.S. Naval Research Laboratory (NRL,) is finding that its Global Ocean Forecast System (GOFS) can provide invaluable information about the polar regions, even to ships sent to break up the ice. Recently, the GOFS helped an ice-breaking research ship navigate safely out of ice-filled waters.

The ship in this instance was the research vessel Nathaniel B. Palmer, performing extended scientific research in the Antarctic Ocean as part of the U.S. Antarctic Program. During research in March, the ship could not maneuver around large ice blocks while traveling through Pine Island Bay in quest of open waters. The GOFS, first developed in 2013, is designed to assimilate data from several sources and calculate/predict current masses and concentrations of sea ice as well as areas of converging or diverging ice. By analyzing data on diverging ice masses, for example, a ship can be provided with a possible path for navigation to open waters.

The captain of the Nathaniel B. Palmer, John-Martin Souza, points to the seven-day forecast provided by the GOFS as the information that was instrumental in finding his way out of ice-congested waters. “With the right imagery and extra support products GOFS provided, I was able to find a way out in only one day, after the previous four days of trying,” said Souza. “Everyone on our ship is grateful for the up-to-date information about the ice conditions.”
