    Using Temperature–Salinity Relations in a Global Ocean Implementation of a Multivariate Data Assimilation Scheme (2008)
    American Meteorological Society
    Details
    Publication Date: 2017-04-04
    Description: In this paper results from the application of an ocean data assimilation (ODA) system, combining a multivariate reduced-order optimal interpolator (OI) scheme with a global ocean general circulation model (OGCM), are described. The present ODA system, designed to assimilate in situ temperature and salinity observations, has been used to produce ocean reanalyses for the 1962–2001 period. The impact of assimilating observed hydrographic data on the ocean mean state and temporal variability is evaluated. A special focus of this work is on the ODA system skill in reproducing a realistic ocean salinity state. Results from a hierarchy of different salinity reanalyses, using varying combinations of assimilated data and background error covariance structures, are described. The impact of the space and time resolution of the background error covariance parameterization on salinity is addressed.

    The Role of the Land Surface Background State in Climate Predictability (2005)
    American Meteorological Society
    Details
    Publication Date: 2021-05-19
    Description: Skill in ensemble-mean dynamical seasonal climate hindcasts with a coupled land-atmosphere model and specified observed sea surface temperature is compared to that for long multi-decade integrations of the same model where the initial conditions are far removed from the seasons of validation. The evaluations are performed for surface temperature and compared among all seasons. Skill is found to be higher in the seasonal simulations than the multi-decadal integrations except during boreal winter. The higher skill is prominent even beyond the first month when the direct influence of the atmospheric initial state elevates model skill. Skill is generally found to be lowest during the winter season for the dynamical seasonal forecasts, equal to that of the long integrations, which show some of the highest skill during winter. The reason for the differences in skill during the non-winter months is attributed to the severe climate drift in the long simulations, manifest through errors in downward fluxes of water and energy over land and evident in soil wetness. The drift presses the land surface to extreme dry or wet states over much of the globe, into a range where there is little sensitivity of evaporation to fluctuations in soil moisture. Thus, the land-atmosphere feedback is suppressed, which appears to lessen the model’s ability to respond correctly over land to remote ocean temperature anomalies.

    Seasonal variation in surface temperature and salinity around Lagos harbour, Nigeria. (2006)
    Nigerian Institute for Oceanography and Marine Research | Lagos, Nigeria
    Details
    Publication Date: 2021-05-19
    Description: Continuous monitoring of Sea and Harbour (Lagoon) Surface temperature and salinity at two stations has been carried out from 1978 to 1981. This paper presents the findings for the period and relates it to the prevailing meteorological regimes. The pattern of sea surface temperature at Victoria beach in the study period shows a clearly defined mean maximum temperature of 29.34oC in April, and clearly defined mean minimum temperature of 25.63 in August. Depending on the year, there may be a less clearly defined mean maximum and minimum temperature in October/November and in January respectively. The pattern of surface temperature in the Harbour station is basically similar. The salinity cycle especially in the Harbour was found to be critically dependent on rainfall. Practical salinity values as low as zero was recorded in the Harbour during the rainy season while in the dry season, values greater than 30.0 were sometimes recorded. The effect of rainfall on sea surface salinity was expectedly less significant.

    The Subduction experiment : cruise report R/V Oceanus cruise number 250 legs 1 and 2 subduction 2 mooring deployment and recovery cruise, 25 January-26 February 1992 (2006)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-25
    Description: 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.

    A compilation of moored current meter data from SYNOP arrays: one and two (September 1987 to July 1991), volume XLVI (2006)
    Woods Hole Oceanographic Institution
    Details
    Publication Date: 2022-05-25
    Description: The Synoptic Ocean Prediction Experiment (SYNOP) was an ambitious, multi-faceted program focused on the dynamics and predictailty of the Gulf Stream and its recirculations. The moored array component contained the arrays; one just downstream of Cape Hatteras (the "Inlet Array"), one near 68°W (the SYNOP "Central Array") and one near 55°W ("SYNOP East") to which this report is addessed. There were two settings of the SYNOP East array, the first, from fall 1987 to summer 1989, contained 42 current meters on 13 moorings straddling the mean axis of the Stream and extending north and south into the two recirculations. The second extended the southernmost six moorings for an additional two years until summer 1991. Performance was excellent and all instruments but one were recovered.

    Description: An array of surface and subsurface moorings were deployed in the Arabian Sea to provide high quality time series of local forcing and upper ocean currents, temperature, and conductivity in order to investigate the dynamics of the ocean's response to the monsoonal forcing characteristic of the area. The moored array was deployed during R/V Thomas Thompson cruise number 40, One Woods Hole Oceanographic Institution (WHOI) surface mooring, two Scripps Institution of Oceanography (SIO) surface moorings and two University of Washington (UW) Profiling Current Meter moorings were deployed. The moorings were deployed for a period of one year beginning in October 1994 as part of the Office of Naval Research (ONR) funded Arabian Sea experiment. Two six month deployments were planned. The moorings were deployed at 15.5°N 61.5°E (WHOI), 15.7°N 61.3°E (SIO), 15.3°N 61.3°E (SIO), 15.7°N 61.7°E (UW), and 15.3°N 61.7°E (UW). The WHOI surface mooring was outfitted with two meteorological data collection systems. A Vector Averaging Wind Recorder (VAWR) and an IMET system made measurements of wind speed and direction, sea surface temperature, air temperature, short wave radiation, long wave radiation, barometric pressure, relative humidity and precipitation. Subsurface instrumentation included Vector Measuring Current Meters (VMCMs), Multi-Variable Moored Systems (MVMS), conductivity and temperature recorders and single point temperature recorders. Expendable bathythermograph (XBT) data and CTD data were collected while in transit to the site and between mooring locations.
