Mike McMahon, [e-mail] @export drop unneeded fields, and make original cols lowercase - finals will be uppercase we record the direction of the current relative to the ship (eg to bow, to starboard, etc), but ICES wants it in a compass direction. I use the tow direction (determined above) combined with the value stored in GSINF.CURNT to derive the value. For example, if the tow was found to be West to East (90deg), and the CURNT value was "to starboard", the combined angle would be 90+90 = 180 (or South) A = AT CAMERON H = Lady Hammond N = Needler S = Teleost V = Venture T = Templeman MINTRAWLDEPTH','MAXTRAWLDEPTH',
