On December l, 1946 Spar’s homeport changed to Wood’s Hole, MA. SPAR was moved again on June l, 1957 to Bristol, RI.

In 1957 SPAR conducted oceanographic operations through the Northwest passage. The culmination of this assignment occurred when the Coast Guard Cutters STORIS, BRAMBLE, and SPAR became the first vessels to circumnavigate the North American continent. President Dwight D. Eisenhower sent his personal congratulations for this significant accomplishment. This impressive history was further added to in 1966 when SPAR logged over 17,000 miles and visited such ports as  / Argentia Newfoundland, Reykjavik and Kefavick Iceland, Tromso Norway, Copenhagen Denmark, Bremerhagen Germany,Keil canal, Belfast Ireland and Jan Mayen Island, while conducting an oceanographic charting expedition in the Northern Atlantic.

Abstract : A joint U.S. Naval Oceanographic Office and U.S. Coast Guard geological, geophysical survey was conducted during the summer months of "1966" on that portion of the mid-oceanic ridge that lies north of Iceland. Preliminary analysis of the data delineates the general form, magnetic signature, and size of the mid-oceanic ridge and several small related fracture zones. It was found that the mid-oceanic ridge between Iceland and Jan Mayen has an average width of about 60 miles and a poorly developed rift valley. East of Jan Mayen, the mid-oceanic ridge is well developed with a rift valley and flank provinces. It had been previously thought that the Jan Mayen Fracture Zone struck east-west in the region east of 5 degrees W. and 71 degrees N. Instead, it was found to be an en echelon feature striking northwest-southeast. This fracture zone extends from the base of the Greenland continental slope to the Norwegian coast. (Author)

Abstract

Near 53°N the crest of the Mid-Atlantic Ridge is offset 370 km in a left lateral sense by a large fault. Smaller subsidiary and parallel fracture zones are found both to the north and south of the primary fault. There is no magnetic signature associated with the fracture zone.

Abstract

An extensive survey of the Mid-Atlantic Ridge from 47° to 51° N. has recovered a large quantity of detailed bathymetric data from the North Atlantic sea floor. Supplemented by seismic reflection and magnetic profiles, these data reveal some surprising characteristics of sea-floor spreading on the Mid-Atlantic Ridge. Closely spaced transform faults, generated about 60 m.y. B.P., extend to crust of about 20 m.y. B.P. age. Significantly, however, demonstrable transform faults are nearly absent on ocean crust younger than about 10 to 20 m.y. B.P. Possibly in response to recent increased spreading rates or increased asthenosphere flow below the spreading axis, the ridge axis has replaced the transform pattern within about the last 20 m.y. B.P. with alternating normal and oblique spreading axes. The normal spreading segments are generating a basement level 0.5 to 1 km higher than that produced by the oblique segments, probably because of greater viscous head losses for magma rising within oblique rifts. The late Tertiary spreading pattern of normal and oblique rift segments has not been stationary with respect to the transform direction but has migrated southward at 1 or 2 mm per yr, possibly a measure of slow southward subaxial motion in the asthenosphere. A problem with this hypothesis is that the rift-valley floor and the regional bathymetry seem to be shoaling very gradually (1:1,000) toward the Azores, which suggests a northward-directed pressure gradient in the asthenosphere. Although the top of the oceanic basement in the northeastern Atlantic deepens with increasing age, there are large depth anomalies with respect to crustal subsidence in the eastern Pacific. Crust of ages 60 to 50 and 10 to 0 m.y. B.P. is elevated about 1 km above coeval Pacific crust, with lesser anomalies occurring elsewhere. Because the highest basement levels seem to correlate with probable times of most intense plume convection, it is inferred that a lithosphere of lower density or thicker crust is formed at such times.

Abstract

Recent detailed surveys by the U.S. Naval Oceanographic Office have delineated three new sea floor ridges in the northern Atlantic. It is postulated that these ridges are sedimentary features formed by depositional processes which in turn are controlled by the flow of Norwegian Sea water.

Boot camp and the cigarette.

A Boot Camp Story, I was in Oscar company summer of 1965. Our CC was a first class petty officer,Gaus, Bm1. Anyway I remember this guy in our company asking for a smoke break while doing maneuvers in the training field. I thought this guy was in trouble now & I was right.  Guas was a real nasty guy. we all stood at attention as he instructed our shipmate to go get his cigarettes from the barracks. Now he also told him to go into his office to get his scotch tape dispenser. This kid was fast he was back in a heartbeat. Guas took out all his cigarettes, made a roll out of them and taped the cigarettes all together. Then he told this guy to stick them in his mouth and light up. Dam if he didn't do it,Guas kept saying take a drag, bigger, bigger, we were sick just watching him, needless to say he never asked for another smoke break again. Guas was hard to beat, but I have to admit, I did beat him and it wasn't really hard to figure out,but I did it without getting caught. The one thing in boot camp could not deprive you of, was religion. I went to a Methodist meeting on a Tuesday night, it was an hour Long. You could smoke as much as you wanted to, then I thought I'll go to the catholic mast on Wednesday night, same deal, with the smoking, I went to the Jewish meetings also, I went to them all and never got caught.
