Data quality control for vessel mounted acoustic Doppler current profiler. Application for the western Mediterranean Sea

Abstract

[ES] Se propone un protocolo sistemático para el control de calidad de los datos obtenidos con un perfilador acústico por efecto Doppler (ADCP) instalado en un buque. Se consideran las circunstancias previas a la adquisición y las simultáneas a la misma. Independientemente de las condiciones técnicas, de localización del instrumento y de su posible desalineamiento, los sistemas auxiliares a la adquisición determinan el rango de precisión de los perfiles de velocidad de la corriente. Las circunstancias de navegación simultáneas a la adquisición permiten determinar y atribuir un grado de significación (o fiabilidad) a cada uno de los perfiles individuales. La formulación del protocolo de control de calidad de los datos se complementa con su aplicación a una campaña realizada en otoño de 1992 a bordo del buque oceanográfico “García del Cid” en el Mediterráneo occidental

FE92 cruise was funded by the Spanish Interministerial Commission for Science and Technology CICYT (MAR89-0550) and Mphmed93 by the Commission of European Communities, Directorate General for Fisheries (DG XIV, MA 3730). This paper is a contribution to the European Union Marine Science and Technology (MAST) programme OMEGA project (contract MAS3-CT95-0001). E.G.-G. research was financially supported by a Generalitat de Catalunya Doctoral Grant “Formació de Personal Investigador”. The manuscript was finished during the postdoctoral appointment of E.G.-G. in JPL/Caltech with financial assistance of the Ministerio de Educación y Cultura (Spain) within “Plan de Formación de Doctores y Tecnólogos en el Extranjero”

[EN] A systematic Data Quality Checking Protocol for Vessel Mounted Acoustic Doppler Current Profiler observations is proposed. Previous-to-acquisition conditions are considered along with simultaneous ones. Independently of internal systems, location and misalignment, the auxiliary systems to acquisition determine the accuracy range of the current velocity profiles. Simultaneous-to-acquisition navigation conditions provide the physically descriptive weight (or reliability) of significance for each individual current profile. The formulation of the Data Quality Checking Protocol is followed by actual applications and examples from cruises aboard R/V "García del Cid" in the Western Mediterranean Sea
