This unbound logbook contains detailed data logs for Eltanin cruise 12 from March 13 to April 18, 1964. Also included is an envelope stapled to the cover verso (back of the cover) containing a graph and map of the southern portion of Argentina and Chile and adjacent regions of Antarctica with plot points for organic carbon, organic carbon in mg/cv. meter, and phytoplankton and zooplankton boundary. Summary of route: the cruise stops at stations in the South Atlantic Ocean and Southern Ocean approximately between 54° w and 34 ° w and 64° s and 58° s. Detailed data log sheets record the following information: Ship and cruise no., station no., sample number, total no. samples, coordinates, date, local time, tow type, net in, net out, length of tow, wire angle at max depth, flowmeter reading, corrected depth range, flowmeter no., displacement vol., flowmeter calibration factor, corrected displ. vol., vol. H20 filtered, wire angle information, sky condition, sea condition, surface water temperature, BT slide no., BT temperatures, hydro station data, surface salinity, core no., secchi disk, comments (successful? If not why?), observer name. The back of these forms record BT slide data. Special hydro station data sheets and "multiple opening and closing plankton tows" sheets are also included. Time-depth recorders, (made by Benthos, Inc), which are approximately 3 inches in diameter, are included with time and depth graphs that accompany some of the detailed log sheets.
