​​U.S. Coast Guard Cutter Spar wlb - 403 out of Bristol RI.
​ A fact - there is 330 million cubic miles of water on this planet. 
The Spar Was A Sea Going Buoy Tender.
On December lst. 1946 Spar’s homeport changed to Wood’s Hole, MA. SPAR was moved again on June lst. 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.
Our Captain at that time was LCDR F.J. Flynn ( Great Captain )

Putting a grand total of just over 17,000 miles under her belt along with the crew & officers & the ten civilians on board who worked for the naval dept.
Sometime after August, 10th the stop to "Jan Mayen Island" was incorporated into the cruise while out at sea, it wasn't planned while we were still in Bristol RI it wasn't posted on the itinerary. We were enroute to Tromso Norway when we were passing by Jan Mayen island.
​One could say it was for some "R and R" / to get off our sea legs.

Oceanography in the Coast Guard.
The scientific study of the oceans has been a part of Coast Guard operations for more than a century. It began when the first Revenue Cutter Service vessels visited Alaska after the territory was purchased from Russia in 1867. They added oceanographic survey work to the long list of their other duties.

Hydrographic Survey Work In The North Atlantic, 1966.

If you were not on this trip or one like it, then you will never know what is like being on a 180 out at sea
​ ( North Atantic ) for nearly 3 months
. We had all types of weather and two monster storms that lasted nearly two weeks each. Some swells were being recorded in the ships log book at 70 / 90 feet high.
 The winds were just as bad. The Spar seen her crew members through it all.

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).

​U.S.C.G. Cutter Spar WLB-403 .

That year,The SPAR conducted hydrographic operations throughout the Northwest Passage in company with the cutters STORIS and BRAMBLE In "1957". When she returned to her homeport in Bristol, RI.The Spar was the first vessel to circumnavigate the North American continent. President Eisenhower sent
​his personal congratulations for this accomplishment.

With most of the Western Hemisphere transits already made the SPAR WLB/403 crossed the North Atlantic in 1966 up past the realm of the Arctic Circle. We Encountered Two very bad storms while out at sea.Each Lasting just under two weeks with swells being logged in on the bridge up to 70 to 90 foot. Winds up to 90 MPH, well over hurricane winds which is 70 M.P.H.our destination was Spitsbergen Germany. Norway where she was called upon to measure the Ocean Topography in the Jan Mayen Fracture Zone area.During this voyage, we were visiting ports in Argentia Newfoundland,Reykjavik IcelandKeflavík Iceland ,Tromso Norway, Jan Mayen Island, Denmark CopenhagenBremerhagen Germany & Through The Keil Canal in Germany, and Belfast Ireland.

North Atlantic Fracture Zones Near - 53 DEGREES.​​
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.

Maps of the sea-floor geology identify the locations where fine-grained sediment and associated contaminants accumulate. Remote-sensing techniques such as side-scan sonar and high-resolution seismic reflection profiling allow detailed mapping of the texture and distribution of sediment types on the sea floor on a regional basis. These maps illustrate that sediment texture and other bottom features are patchy and that major changes occur over a wide range of spatial scales. The variability is due to the irregular bottom topography, past and present sources of sediment, and the processes causing transport. Maps show the location and extent of erosional and depositional environments and provide a regional context for the interpretation of bottom samples and benthic observations. Fine-grained sediments typically indicate areas of sediment accumulation; coarse-grained sediments or boulders define areas where the sediments are scoured and winnowed by currents.

THE Mid-Oceanic Ridge, a broad fractured arch more than 40,000 miles long
, is the largest tectonic feature on the surface of the Earth. Associated with the centre of the ridge over much of its length is an axial fracture or rift which is the locus of shallow earthquakes. An extension of this world encircling ridge into the Greenland Sea and Arctic Ocean was first hypothesized on the basis of a well defined pattern of earthquake epicentres and a few spot soundings1,2. The topographic form of the ridge was first revealed by precision depth records obtained during the pioneer polar crossings of the nuclear submarines Nautilus3 and Skate4. The Arctic Mid-Oceanic Ridge does not bisect the entire Arctic Basin but lies midway between the monolithic, aseismic Lomonosov Ridge and the Eurasian continental margin.

Atlantic Ocean Properties, Salinity
The waters at the surface of the North Atlantic Ocean are saltier than those of any other ocean - but not near Canada! The reasons for this high salinity are related to the flow of currents, the rate of evaporation, precipitation, river inflow, and melting of sea ice. Currents may bring high salinity water into the North Atlantic from surrounding saltier seas. The rate of evaporation plays a role in determining salinity. The higher the rate of evaporation, the higher the salinity, because the salt to water concentration increases as water evaporates. Increased levels of precipitation, as in equatorial regions, will decrease salinity by diluting the salt water. River inflows also dilute salt concentrations, and so too does the melting of sea ice. The outflow from the Mediterranean Sea brings very salty water into the North Atlantic, and is the largest contributing factor to the salinity of this part of the ocean.
Then and now in the Coast Guard.
​In between all of this Information that I have collected for the SPAR wlb-403
while searching the archives for all this information a lot of memories are returning to me. I remember the 10 civilians working under the navy's department bringing all their gear and electronics on board. Getting ready for the survey. I don't believe back then that the crew really knew what was going on. I have more interest in it now then in 1966. Their equipment wasn't just placed anywhere it had to be secured in a very special way and that was to weld all the equipment to the decks. Where ever they choose to put It at the time I wondered why are they welding all this equipment down. It felt like it was going to be permanent for some reason but I soon learned when we were out at sea why? If they hadn't have welded it to the deck it would have been everywhere and severely damaged also someone could have been hurt. The two storms we encountered while at sea would have been the proof of such a mishap. Its kind of interesting to me now. I wish I could go back as I think a lot of us do. The way the guard is today is a different ball game. I'm not taking away the fact that in our time  years ago when we served in the Coast Guard.

This song (Stranger on The Shore) I played on the juke box whenever I had liberty while attending engineering school in groton conn. back in 1965 I wore the record out brings back many memories for sure. Soon after that I was transferred onto to the 
SPAR-403 and in 1966 we went for one hell of a cruise into the North Atlantic.

​Dad,
​​Your web site is amazing!!!!
I spent a good chunk of time looking at it today with my friend at work. She loved it, too and asked me to email her the link so she can continue to look at it at home. You should be proud of all of the hard work you've put into this. It is so interesting and enjoyable to go through!
Can't wait to continue going through it (it's long!!!)
Love always, Andrea  4 / 21 / 2010

Thanks Andrea that means so much to Me. ​

​In 1963 the existence of a transform fault near latitude, 53N was first postulated on the basis of earthquake epicenter data by Bruce Heezen and Maurice Ewing. Also the study of ocean currents indicated that there should be a deep passage through the Mid-Atlantic Ridge. In 1966 the area was investigated by USCGC Spar (WLB-403) on its return from an Arctic survey.The fault was named Charlie Fracture Zone after the USCG Ocean Weather Station Charlie at 52°45′N 35°30′W, athwart the fault. In July 1968 USNS Josiah Willard Gibbs (T-AGOR-1) conducted a more extended survey.It was proposed that the fracture zone be renamed Gibbs Fracture Zone, as fracture zones are generally named for research vessels. The proposal was accepted only in part, and currently the official name is Charlie-Gibbs Fracture Zone. Note that the double name refers to the two parallel fracture zones together. The individual fracture zones have to be referred to as Charlie-Gibbs North and South.

​"1966" North Atlantic Storms
With all honesty I can remember the one Storm's name we encountered & it lasted a day short of two weeks.
Her name was Hurricane Dorothy.  When the storm was over the officers took their chart readings and calculated that we had advanced one ( 1 ) mile in two weeks.
​Going by this chart for 1966 the second storm seems to be Hurricane Lois. Just as bad as Dorothy.
