Dashed line off the south Atlantic coast denotes approximately the 10-fathom depth curve. in a vertical from this point at the base of the dorsal fin. Standard length-body depth ratios were calculated to the nearest hundredth and rounded to the nearest tenth. Water-depth data for a station often included a range through which the collecting gear (usually bottom trawls) was used (for example, "25 to 27 fathoms"). A mean depth value, rounded to the nearest fathom, was determined (in this example, 26 fathoms). Station localities are midpoints between the start and finish of trawling drags. 21.
