This report presents the procedures and methods used to obtain total carbon dioxide (C{sub T}), total alkalinity, and underway pCO{sub 2} data during the F/S Meteor Cruise 18 in the North Atlantic Ocean (WOCE Section A1/E). The F/S Meteor departed Reykjavik on September 2, 1991 and docked in Hamburg early on the morning of September 25, 1991 after 24 days at sea. A two day steam from Reykjavik brought the ship to the starting position for WOCE zonal section A1/east (A1/E) on September 5. Section work began and ended with a closely spaced series hydrocasts on the SE-Greenland (60{degree}N 42{degree}30 minutes W) and Porcupine Shelves (52{degree}20 minutes N 14{degree}15 minutes W), respectively. The cast schedule was interrupted for equipment problems (6 and 7 September), current meter deployments (9, 10, 11, 14, and 19 September), and by high seas (13, 14, and 17 September). Of 64 CTD casts made, 58 were bottle casts including two calibration stations. Measurements made included CTD pressure, temperature, salinity, bottle salinity, oxygen, phosphate, nitrate, nitrite, silicate, total alkalinity, CFC`S, total carbon dioxide, and continuous underway pCO{sub 2} of surface waters. Carbonate samples were collected from 31 section stations (55.4% of the section stations), one test station, and two calibration stations. Repeated XBT, and ADCP profiles were taken throughout the cruise. Instructions for accessing the data are provided.
