R/V Neil Armstrong - 1st ever visit to Great Lakes by Woods Hole Oceanographic

[LongLine]

First time ever to Great Lakes.  From Woods Hole Oceanographic Institute.

 

 

 

 

 

A research vessel more accustomed to supporting science on the open ocean is embarking on a first-of-its-kind, 2,531-nautical-mile journey through the Great Lakes to help scientists investigate some of the universe's most elusive elementary particles.

 

The Woods Hole Oceanographic Institution’s (WHOI) research vessel (R/V) Neil Armstrong departed its home port of Woods Hole, Massachusetts, on October 28 bound for Duluth, Minnesota, where it is expected to arrive around November 9. The 238-foot vessel will travel through a network of rivers, locks, and inland waterways on its 11-day journey to reach the far western end of Lake Superior, where it will support an effort to detect neutrinos in the lake’s natural water.

 

The project, known as the Experimental Neutrino Detector (END), is led by the University of Minnesota Duluth (UMD) and sponsored by the Defense Advanced Research Projects Agency (DARPA), in cooperation with the US Department of Energy’s (DOE) Office of Science, Fermi National Accelerator Laboratory (Fermilab), and Brookhaven National Laboratory. Neutrinos are subatomic particles that rarely interact with matter, making them exceptionally difficult to detect. Scientists study them to understand fundamental properties of the universe, such as why it is made mostly of matter rather than antimatter.

 

WHOI’s Mooring Operations and Engineering (MOE) Group led the design and assembly of five detector arrays that will support underwater sensors central to the research. Once in Duluth, Neil Armstrong and its crew will transport the equipment several miles offshore near Two Harbors, Minnesota, lower the frames onto the lakebed, and install fiber-optic cables connecting the detectors to shore. The frames, each approximately 30 feet tall and weighing about 8,000 pounds with mounted equipment, must be positioned with precision to support the experiment.

 

This journey highlights the specialized role of the US Academic Research Fleet. Research vessels are more than transportation; they serve as floating laboratories, equipped with the people, technology, and operational capabilities needed to deploy scientific instruments, collect data, and sustain research in challenging environments.

(Not the best time of year to be on Lake Superior, but wishing them a safe trip)

That’s pretty cool !
