The officers, scientists, and crew of the NOAA Ship Fairweather have started their 30-day Arctic reconnaissance survey, and you can watch their progress on NOAA’s ship tracker website.
The diagram on the right shows the corridor Fairweather will travel during this survey project. (Fairweather’s survey corridor is shown in green.) The ship will zigzag back and forth within that corridor, checking actual depth soundings against measurements acquired during the 20th century or even earlier. (See the vintage of the depth measurements in the Aug 1 blog post, Arctic reconnaissance survey checks old soundings to prioritize future surveys.)

Arctic reconnaissance survey checks old soundings to prioritize future surveys
NOAA’s Office of Coast Survey, Alaska, and the nation’s economic vitality have been intertwined for 145 years. We strengthen that bond on August 1, as NOAA Ship Fairweather begins a reconnaissance survey to the northernmost tip of the Alaska’s Arctic coast. Fairweather will check soundings along a 1,500 nautical mile coastal corridor from Dutch Harbor, Alaska, to the Canadian border. (At least, we hope Fairweather can go all the way to the Canadian border… The ice cover is a little stubborn this summer, and may not recede sufficiently for safe passage. CMDR Jim Crocker, the ship’s commanding officer and chief scientist of the party, will keep us updated through the coming weeks. Watch this blog site for Fairweather updates!)
