That, I can't say. I was at the commisioning of the Coast Guard R&D Center in Groton, 50+ years ago, and it moved across the river to a big facility in New London.
Here is the place to look for research. I did look up the R&D center a while back with my impending 50 year anniversary of service. I was in the Physics branch and knew buddies in oceano.
Our guy Dennis got multispectral photos of ice with a Hasselblad UV-Sonnar. Quartz and CaF elements. Who can forget that?
