This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the research progress of the second year of research under ''Measurement of Surface Ocean Carbon Dioxide Partial Pressure During WOCE'' and proposes to continue measurements of underway pCO2. During most of the first year of this grant, our efforts to measure pCO2 on WOCE WHP legs were frustrated by ship problems. The R/V Knorr, which was originally scheduled to carry out the first work on WHP lines P19 and P16 in the southeastem Pacific during the 1990-91 austral summer, was delayed in the shipyard during her mid-life refit for more than a year. In the interim, the smaller R/V Thomas Washington, was pressed into service to carry out lower-latitude portions of WHP lines P16 and P17 during mid-1991 (TUNES Expedition). We installed and operated our underway chromatographic system on this expedition, even though space and manpower on this smaller vessel were limited and no one from our group would be aboard any of the 3 WHP expedition legs. The results for carbon dioxide and nitrous oxide are shown. A map of the cruise track is shown for each leg, marked with cumulative distance. Following each track is a figure showing the carbon dioxide and nitrous oxide results as a function of distance along this track. The results are plotted as dry-gas mole fractions (in ppm and ppb, respectively) in air and in gas equilibrated with surface seawater at a total pressure equal to the barometric pressure. The air data are plotted as a 10-point running mean, and appear as a roughly horizontal line. The seawater data are plotted as individual points, using a 5-point Gaussian smoother. Equal values Of xCO2 in air and surface seawater indicate air-sea equilibrium.

This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Progress during the past year of research under ''Measurements of Surface Ocean Carbon Dioxide Partial Pressure During WOCE'' has been significant. As was described in our previous progress report, the startup phase of this research was severely frustrated by delays in the US WOCE Hydrographic Program (WHP), which in turn were caused by delays in the mid-life refit of the R/V Knorr. As a result the high latitude southeastern Pacific work (WHP lines P19S and P16S) originally scheduled for the 1990 austral summer has still not been carried out. As a substitute, the smaller R/V Thomas Washington was pressed into service during mid-1991 to carry out lower-latitude portions of the WHP P16 and P17 lines - the TUNES Expedition. Because this ship is much smaller than the R/V Knorr, she could not carry a full complement of WHP programs and seagoing personnel and was restricted by her size and the time of year to lower-latitude work. Our original proposal for carbon dioxide measurements was designed to divide the work between legs in which we participated as part of the WHP dissolved CFC program (under separate NSF funding) and legs in which we entrusted the operation of our system to other CFC or carbon dioxide laboratories with expertise in gas chromatography. Since we were not involved in any CFC work on the substituted Washington expedition, and since all the seagoing programs on the Washington were additionally stressed by a shortage of people and space, this placed our carbon dioxide program at an unwelcome disadvantage. The preliminary results for carbon dioxide and nitrous oxide are shown. We are forced to rely on spotty manual observations and station CTD temperatures to reconstruct our equilibrator temperature solubility corrections for portions of that leg. We did not get our usual reliable data return, but the results were surely worth effort, especially for this vast and rarely-visited region of the world oceans.

This book was released on 1992 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the fist year of this two-year grant, we have completed the data acquisition phase at sea along the WOCE-S4 section located along 67°S between 73°W and 172°E in the Pacific sector of the Southern Ocean. The expedition was carried out aboard the Russian Research Ship ''Akademik IOFFE'' in the period February 14 through April 6, 1992. The total CO2 concentration and pCO2 in a total of about 1290 water samples were determined using a coulometer for total CO2 and an equilibrator/gas chromatograph system for pCO2. Surface water samples were analyzed at all the 112 hydrographic stations occupied. Complete or partial profiles were obtained at 58 stations. In addition, a total of 172 determinations were made at sea for 62 bottles of the Standard Reference Solution.

Progress Report, [January 1, 1993--December 31, 1993]. written by and published by . This book was released on 1993 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the first year of the grant, we participated in three WOCE expeditions (a total of 152 days at sea) in the South Pacific Ocean, and the field phase of the proposed investigation has been successfully completed. The total CO2 concentration and pCO2 were determined at sea in 4419 water samples collected at 422 stations. On the basis of the shipboard analyses of SIO Reference Solutions for CO, and a comparison with the results of previous expeditions, the overall precision of our total CO2 determinations is estimated to be about ±2 uM/kg. The deep water data indicate that there is a CO2 maximum centered about 2600 meters deep. This appears to represent a southward return flow from the North Pacific. The magnitude and distribution of the CO, maximum observed along the 135.0°W meridian differ from those observed along the 150.5°W meridian due to Tuamotu Archipelago, a topographic high which interferes with the southward return flow. The surface water pCO2 data indicate that the South Pacific sub-tropical gyre water located between about 15°S and 50°S is a sink for atmospheric CO2.

Available in PDF, EPUB and Kindle. Book excerpt: This data documentation discusses the procedures and methods used to measure total carbon dioxide (TCO2) and partial pressure of CO2 (pCO2) in discrete water samples during the Research Vessel (R/V) Akademik Ioffe Expedition in the South Pacific Ocean. Conducted as part of the World Ocean Circulation Experiment (WOCE), the cruise began in Montevideo, Uruguay, on February 14, 1992, and ended in Wellington, New Zealand, on April 6, 1992. WOCE Section S4P, located along (approximately)67°S between 73°W and 172°E, was completed during the 51-day expedition. One hundred and thirteen hydrographic stations were occupied. Hydrographic and chemical measurements made along WOCE Section S4P included pressure, temperature, salinity, and oxygen measured by a conductivity, temperature, and depth sensor; bottle salinity; bottle oxygen, phosphate; nitrate; nitrite; silicate, TCO2; and pCO2 measured at 4 C.
