Sallarès, Valentí Bornstein, G. Mojica, J.F. European Geosciences Union General Assembly 2015 (EGU2015), 12-17 April 2015, Vienna, Austria.-- 1 page We present a methodology for inverting temperature and salinity from time and space-coincident acoustic reflectivity and XBT data. This method recovers low frequency content (< 10 Hz) of the impedance from XBTs and the high frequency content (> 10 Hz) from acoustic reflectivity. Afterwards, maps of temperature and salinity are calculated from impedance using the GSW equations of state and an empirical T-S relation. Acoustic data allows to recover the main physical parameters of the ocean along lateral sections of hundreds of km, covering all the full-depth water column and with vertical and lateral resolutions of 10 m and 100 m, respectively. This method was applied in the Gulf of Cadiz, NE Atlantic Ocean to recover the main physical oceanographic parameters in the ocean with accuracies of δTsd = 0.1 C, δSsd = 0.09 and δsd = 0.02kg/m3 for temperature, salinity and potential density. Inverted temperature anomalies reveal baroclinic thermohaline fronts with intrusions.The observations support a mix of thermohaline features created by both double-diffusive and isopycnal stirring mechanisms Peer Reviewed 2016-11-30T10:25:48Z 2016-11-30T10:25:48Z 2015-04-16 2016-11-30T10:25:49Z póster de congreso http://purl.org/coar/resource_type/c_6670 issn: 1607-7962 Geophysical Research Abstracts 17: EGU2015-12034 (2015) http://hdl.handle.net/10261/140973 Publisher's version http://meetingorganizer.copernicus.org/EGU2015/posters/17345 Sí open European Geosciences Union |
