UEC-1 Deployment 1 Results |
15OCT98 to 25NOV98
This was the first deployment of an UEC on NR-1. It lasted approximately 6 weeks.
The following observations were made about UEC-1 and its payload upon its return. You may click on the thumbnails of the pictures to see an enlarged version.
A more detailed photos of the results from the straingages is availible in the download section of the web site.

UEC-1 appeared to hold up fairly to its 5 week bath. The stainless steel screws had some slight corrosion. The cable-ties use to secure the experiments to the pallets became brittle (almost certainly due to being exposed to cold water) and could be broken by hand.

The zinc planted ubolt was surprisingly intact. It was missing a
lot of paint, however.

Our very crudely mixed and poured block of syntactic foam survived.
It measured about 1.5" thick and 8" in diameter. Notice the large amount of sediment on the upper surface and sides.

The Rubbermaid Tupperware did not serve as a good compensating
tank. All three tanks hand air bubbles and some seawater contamination. The air bubbles
can be seen in the photos. The 9volt Alkiline batteries did not survive. The contaminated tank (far left). |

The lowest pallet in in UEC-1 had two of the three strain gages
mounted on it. Notice the large amount of sediment on the pallet. The amount of sediment
increases as one moved down the tube. This is most likely the sediment that is kicked up by the aft thrusters of NR-1, while the ship was maneuvering near the bottom. |
