Abstract

REPORT OF UNDERWAY pCO2 MEASUREMENTS IN SURFACE WATERS REPORT OF UNDERWAY pCO 2 MEASUREMENTS IN SURFACE WATERS AND THE ATMOSPHERE DURING October 2009 R/V Laurence M. Gould 09/10 S. C. Sutherland, Timothy Newberger, Taro Takahashi, and Colm Sweeney Lamont-Doherty Earth Observatory of Columbia University Palisades, NY 10964 10 November 2009 Part 1 - Data Processing and Quality Control. 1. General a) Cruise Overview 1) This is a resupply trip to Palmer Station, and accompanying oceanographic research. It is listed as opening Palmer Station #2, and opening COPA and Cape Sherriff. 1. b) Data Overview 1) The pCO 2 data are fine. No editing was required. 2) The temperature data also appear to be fine. 3) The atmospheric pCO 2 observations were not very well behaved as usual. There are some reasonable values when the wind is near dead ahead. 4) The chlorophyll A data from the WetLabs Fluorometer is also appears to be fine. It is very low, but there are a couple of small peaks associated with decreases in pCO2. 2. Standards: Cylinder Concentration (ppm) Nitrogen (UHP) 0.0 CA06684 120.66 CA06616 359.49 CA06653 252.31 CA07203 505.57 CA07234 374.86 A 4 th order calibration curve is used with 5 standards, not including the Nitrogen, as described in Section 2. The calibration curves are also plotted in Section 4. Standards flow for about 120 seconds before an observation is made., 3. Details of pCO2 data. There were 3,885 individual seawater pCO 2 observation, none were rejected. 4. Details of temperature data. a) The temperature of water in the equilibrator is monitored continuously using a Guildline platinum resistance thermometer (readable to 0.05 o C and regularly calibrated against a mercury thermometer traceable to N.I.S.T.) and recorded on the data-logging computer. The calibration curve is integ
