(yes or no), if not successful, what was wrong?, observer name. Some detailed logs are accompanied by sheets entitled "Lamont multiple opening-and-closing plankton tows", which record the following information: action, time, calc. depth, wire rate, wire angle, wire out, depth upper, depth middle, depth lower, depth, total time, meter reading, meter factor, mater number, vol. filtered, label no., remarks.
