Last summer, NOAA Ship Fairweather went farther north than ever before.
Fairweather’s survey of over 5,500 linear nautical miles in 2025 will provide valuable environmental information for the U.S. Coast Guard’s Port Access Route Study, a multi-year effort to establish new maritime traffic routes, safety zones, and use areas in the U.S. Arctic waters.
Establishing areas of safe passage through the Arctic ensures that ships remain within surveyed waters to avoid running aground, and larger ships avoid scraping along the coast, potentially disturbing whaling areas and coastal communities.
During the survey, Fairweather’s crew experienced Arctic wonders from the surface of the water to the seafloor. In the Chukchi Sea, hydrographers noticed ice scours in the seabed generated by years of friction between floating sea ice and the sediments below. Crewmembers also climbed to the flying bridge to observe flickering, green northern lights dazzling the night sky. Wildlife sightings were frequent, and featured walruses, sea lions, gray whales, fin whales, bowhead whales, and even a swimming polar bear.
