1200 hours, August 12, 2012: 70°38.7’N 162°06.6’W, approximately 22 miles north of Icy Cape, Alaska’s North Slope
In 1963, the town of Point Hope (68° 21’N 166°46’W) – a small, ancient, and archeologically-significant Inupiaq community on Alaska’s North Slope that remains at present a largely native village – narrowly avoided the creation of an artificial harbor by underwater hydrogen bombs. Part of “Project Plowshare,” the planned creation of a deepwater harbor by thermonuclear power was intended to demonstrate the peaceful use of nuclear power for construction purposes. It was opposed by Native American communities, scientists in the state, and the Episcopalian church across the United States. The protest has been credited as one of the first government projects successfully challenged on the grounds of its potential environmental impact.
How do ocean explorers know where to look when they investigate and document the historical secrets of the deep? Well, archaeological expeditions use a myriad of modern surveying technologies. Recently, when NOAA’s Monitor National Marine Sanctuary was investigating a World War II underwater battlefield site, they called on a surveying expert with NOAA’s Coast Survey to assist.
Before we get to the Fairweather logs, we need to update the last post, NOAA Ship Fairweather zigzags her way to accurate and precised depth soundings. Cmdr. Crocker reports that the “normal” zigzagging won’t start until they head further north, starting near Point Hope. It was not planned for the trip to Kotzebue, and he would have run a straight course if he could have. This log by Ensign Hadley Owen explains why they zigzagged earlier than planned, as well as what they are doing for their first scientific project. We apologize for the error in the last post. -DF
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.)
