An Index Chart I shows the overall track of the cruise. Tracks for the oceanic front survey in the insert at 30N, 70W are shown on Index Chart II. This thermal front study from R/V CHAIN was augmented by an aircraft infrared radiometer survey made by the weather reconnaissance squadron 4 out of Jacksonville, Florida. The flight pattern of SNOWCLOUD SIX is shown on Index Chart III. There are 35 charts (19 plotted on a Mercator Projection (scale 1 degree longitude equals 4 inches) and 16 plotted on a VLC 30-22 chart and enlarged) showing the track of R/V CHAIN over the entire cruise. Echo sounding records were taken during the cruise. They are shown only on the ship's track to and from the work areas, at breaks in the slope. All soundings are based on sound velocity of 4800 ft./sec., and are corrected for depth of transducer. Loran A was used until 19 May (0724) and Loran C used for remainder of the cruise as noted on the charts. Included also is a Station Log, Regular and Expendable Bathythermograph Listings, and a Fish Tow Log. (Author)
