Laboratory for samples processing.

Mediterráneo Servicios Marinos has a fully equipped laboratory for the processing and analysis of sediment, water and biological samples.

Granulometry tests are carried out according to European Norm UNE-EN 933 for marine and terrestrial sediments characterisation. This is a preliminary step for various studies regarding engineering, construction and biological research activities.

The ammount of parameters obtained through water sampling analysis are numerous. Among them: Amoniac, DBO, DQO, Nitrates, phosphates….

Also the Mediterráneo Servicios Marinos laboratory carry out various tests to determine and characterize marine biological samples and macrofauna . In the other hand is also specialized in demographic and lepidocronologic studies of phanerogam fields.

Marine Research Tanks.

Mediterráneo Servicios Marinos has sea water tanks within our installations to carry out a variety researches which requires the control of a number of physical and chemical water properties like: salinity, temperature, light, etc…

All this is possible thanks to four sea water independent recirculating systems with the most advanced technology including temperature control, sand filters, skimmers, ozone control, ultra violet lamps etc. Also underground high volume tank systems offer a inertia of all the parameters assuring their stability without abrupt changes.
