    The Subduction experiment : cruise report R/V Oceanus : cruise number 240 leg 3 : subduction 1 mooring deployment cruise, 17 June-5 July 1991
    (Woods Hole Oceanographic Institution, 1993-03) Trask, Richard P. ; Brink, Nancy J.
    Subduction is the mechanism by which water masses formed in the mixed layer and near the surface of the ocean find their way into the upper thermocline. The subduction process and its underlying mechanisms were studied through a combination of Eulerian and Langrangian measurements of velocity, measurements of tracer distributions and hydrographic properties and modeling. An array of five surface moorings carrying meteorological and oceanographic instrumentation were deployed for a period of two years beginning in June 1991 as part of an Office of Naval Research (ONR) funded Subduction experiment. Three eight month deployments were planned. The initial deployment of five surface moorings took place during the third leg of R/V Oceanus cruise number 240. The moorings were deployed at 18°N 34°W, 18°N 22°W, 25.5°N 29°W, 33°N 22°W and 33°N 34°W. A Vector Averaging Wind Recorder (VAWR) and an Improved Meteorological Recorder (IMET) collected wind speed and wind direction, sea surface temperature, air temperature, short wave radiation, long wave radiation, barometric pressure and relative humidity. The IMET also measured precipitation. The moorings were heavily instrumented below the surface with Vector Measuring Current Meters (VMCM) and single point temperature recorders. Expendable bathythermograph (XBT) data were collected and meteorological observations were made while transitting between moonng locations. This report describes the work that took place during R/V Oceanus cruise 240 leg 3. It includes a description of the instrumentation that was deployed,information about the XBT data collected and plots of the data as well as a chronology of the cruise events.

    An array of five surface moorings carrying meteorological and oceanographic instrumentation was deployed for a period of two years beginning in June 1991 as part of an Office of Naval Research (ONR) funded Subduction experiment. Three eight month deployments were carried out. The five mooring locations were 18°N 34°W, 18°N 22°W, 25.5°N 29°W, 33°N 22°W and 33°N 34°W. Two Woods Hole Oceanographic Institution (WHOI) and three Scripps Institution of Oceanography (SIO) moorings collected oceanographic and meteorological data, using a 3-meter discus or 2-meter toroid buoy and multiple Vector Measuring Current Meters (VMCMs), an Acoustic Doppler Current Profiler (ADCP) and Brancker temperature recorders (tpods). The surface buoys carried a Vector Averaging Wind Recorder (VAWR) and, on four of the five moorings, an Improved Meteorological Recorder (IMET) which measured wind speed and wind direction, sea surface temperature, air temperature, short wave radiation, barometric pressure and relative humidity. The IMET also measured precipitation. The VMCMs, ADCP and tpods, placed at depths 1 m to 3500 m, measured oceanic velocities and temperatures. This report presents meteorological and oceanographic data from the WHOI Upper Ocean Processes Group (UOP) and the SIO Instrument and Development Group (lDG) instruments and contains summaries of the instruments used, their depths, mooring positions, mooring deployment and recovery times, and data return. Appendices contain information on supplementary Subduction data sets.

    Arabian Sea mixed layer dynamics experiment data report
    (Woods Hole Oceanographic Institution, 1997-07) Baumgartner, Mark F. ; Brink, Nancy J. ; Ostrom, William M. ; Trask, Richard P. ; Weller, Robert A. ; Dickey, Thomas D. ; Marra, John F.
    The Arabian Sea is characterized by strong, large-scale atmospheric forcing during the summer (southwest) and winter (northeast) monsoons. To investigate air-sea interactions related to this unique surface forcing, a moored array was deployed from 15 October 1994 to 19 October 1995 just south of a region that experiences the climatological maximum winds during the summer monsoon. The array consisted of two Scripps Institution of Oceanography surface toroid buoys, two University of Washington subsurface moorings and a surface 3 m discus buoy deployed by the Woods Hole Oceanographic Institution (WHOI). The WHOI buoy carried redundant meteorological packages to measure wind speed and direction, air temperature, relative humidity, barometrc pressure, incoming short- and long-wave radiation and precipitation. Oceanographic instrumentation was deployed on the WHOI buoy's bridle and mooring line to collect time series of temperatue, salinity and velocity at various depths. Four multi-varable moored systems (MVMS) were also deployed along the mooring line by the Lamont-Doherty Earth Observatory and the University of California at Santa Barbara to record both bio-optical and physical parameters. This report describes the instrumentation deployed on the WHOI buoy and the processing and editing of the returned data. The data are then summarized in graphical and tabular formats.

    Pan American Climate Studies (PACS) data report
    (Woods Hole Oceanographic Institution, 2000-03) Anderson, Steven P. ; Huang, Kelan ; Brink, Nancy J. ; Baumgartner, Mark F. ; Weller, Robert A.
    The surface mooring component of the NOAA Pan American Climate Study (PACS) took place from April 1997 to September 1998 in the eastern tropical Pacific. PACS was a NOAA funded study with the goal of investigating links between sea surface temperature variability in the tropical oceans near the Americas and climate over the American continents. Two air-sea interaction surface moorings were deployed along 125°W, spanning a strong meridional sea-surface temperature gradient. One mooring site was located in the cold tongue south of the equator, and the other site was in the region of warm ocean found north of the equator, near the northernmost summer location of the Intertropical Convergence Zone. The moorings were deployed to improve our understanding of air-sea fluxes and the procsses that control the evolution of the sea surface temperature field in the region. Four air-sea interaction buoys were deployed to occupy two sites for a period of 17 months. The sites were along 125°W near 3°S and 10°N. The Upper Ocean Processes Group at WHOI deployed the first two moorings in April 1997. These moorings were replaced with a second pair of moorings in December 1997. The final recovery occurred in September 1998. Each of these buoys on these moorings were equipped with meteorological instrumentation, including a Vector Averaging Wind Recorder (VAWR) and an Improved METeorological (IMET) system. The moorings also carried Vector Measuring Current Meters (VMCMS), single point temperature recorders and a few conductivity sensors on the mooring line to monitor the upper 200m of the ocean. In addition to the traditional instruments, several other experimental instruments were deployed with limited success on the mooring line including acoustic current meters, acoustic rain gauges and bio-optical instrument packages. This report describes the instrumentation deployed on the PACS surface moorings, along with information on the processing and quality control of the returned data. It presents a detailed overview of the meteorological and physical oceanographic data including time series plots, statistics and spectra of key parameters. It also presents analysis of the estimated air-sea heat, moisture and momentum fluxes.

    Subduction is the mechanism by which water masses formed in the mixed layer and near the surface of the ocean find their way into the upper thermocline. The subduction process and its underlying mechanisms were studied through a combination of Eulerian and Langrangian measurements of velocity, measurements of tracer distrbutions and hydrographic propertes and modeling. An array of five surface moorings carrying meteorological and oceanographic instrumentation were deployed for a period of two years beginning in June 1991 as part of an Office of Naval Research (ONR) funded Subduction experiment. Three eight month deployments were planned. The initial deployment of five surface moorings took place during the third leg of R/V Oceanus cruise number 240. The moorings were deployed at 18°N 34°W, 18°N 22°W, 25.5°N 29°W, 33°N 22°W and 33°N 34°W. A Vector Averaging Wind Recorder (VAWR) and an Improved Meteorological Recorder (IMET) collected wind speed and wind direction, sea surface temperature, air temperature, short wave radiation, barometric pressure and relative humidity. The IMET also measured precipitation. The moorings were heavily instrumented below the surface with Vector Measuring Current Meters (VMCM) and single point temperature recorders. Expendable bathythermograph (XBT) data were collected and meteorological observations were made while transitting between mooring locations. This report describes the work that took place during R/V Oceanus cruise 250 which was the second scheduled Subduction mooring cruise. During this cruise the first setting of the moorings were recovered and redeployed for a second eight month period. This report includes a description of the instrumentation that was deployed and recovered, has information about the underway measurements (XBT and meteorological observations) that were made including plots of the data and presents a chronology of the cruise events.
