_El objetivo general es la vigilancia medioambiental de la zona afectada por el dragado del puerto de Maó, mediante el seguimiento de variaciones en la granulometría, del contenido de carbono orgánico y contaminantes metálicos y orgánicos, en esa zona.

The aim of this cruise was to collect surficial sediments from different areas of the Mediterranean Spanish coast for studying the spatial and temporal trends of persistent organic pollutants (organochlorinted pollutants, trace metals and aromatic hydrocarbons) and metal contamination in this environmental matrix. This cruise was included in the activities of the project 2-ESMARME from the IEO (Spanish Oceanographic Institute). This project gives fulfillment to the Annex II of the mission of management of the Ministry of Environment and Rural and Marine Affairs to the IEO on scientific and technical assistance related to the monitoring of the marine contamination and biological effects in the Mediterranean coast of Spain, within the framework of the Barcelona Convention for the protection of the marine environment and the coastal Region of the Mediterranean Sea.

The completion of the dredging of the commercial area of the port of Mahon and disposal of these sediments and dredged materials in an area close to the port, a benchmark that area is needed before the completion of the discharge. The MAO DRAGAT project includes activities to be developed for this purpose. The hydrodynamic characterization and sampling of contaminants in the water column and sediment discharge area is one of the objectives of this project. MAHON 0114 The campaign is designed to perform this characterization by a network of hydrographic stations, ADCP Doppler and sampling in the water column and sediments.
