description |
Maintenance and Update Frequency: notPlanned Statement: 1. Satellite data Sea surface height (SSH) gridded data were obtained from the DUACS (Data unification and Altimeter combination system) products over the Southern Ocean region [146° E, 158° E], [52.5° S, 57.5° S] during the Southern Hemisphere spring from October 16 to November 16, 2018. The satellite dataset has daily SSH data, in a 0.25° × 0.25° spatial grid, encompassing the 16° longitude × 5° latitude region. The absolute dynamic topography (adt) that is the SSH above geoid was used to identify the core of the PF meander. The adt is obtained from the calculation: adt=sla+mdt, where sla is sea level anomaly and mdt is mean dynamic topography. 2.In situ observations: voyage data a. Triaxus data The Triaxus instrument was towed behind the ship and equipped with the Seabird SBE911 CTD 25 sensor to record pressures, conductivity and temperature data. Other sensors were also installed to collect other hydrologic data like dissolved oxygen. Pressure, conductivity and temperature data were calculated using calibration factors provided by Sea-Bird and calibrations provided by CSIRO. The data were processed by automated QC to remove spikes and out-of-range values. Triaxus profiles were limited to 300 m depth with a vertical resolution of 1 dbar and an approximate 0.9-1.5 km lateral spacing between vertical Triaxus casts (averaged every 5 minutes). The oxygen data was directly measured from the dissolved oxygen sensors. The salinity was the absolute salinity. The temperature was converted to the conservative temperature at each depth. The potential density was derived from absolute salinity and conservative temperature. The Gibbs-SeaWater (GSW) Oceanographic Toolbox in MATLAB was applied for evaluating these thermodynamic properties (absolute salinity, conservative temperature, potential density and in situ density) of seawater. b. Shipboard ADCP data Shipboard Acoustic Doppler Current Profiler (SADCP) mounted on the ship hull was used to determine absolute ... |
