Plastic debris and jellyfish swarms spotted in Mediterranean

July 12, 2013

An international research team working on the MedSeA project, coordinated by Patrizia Ziveri, of the UAB, in collaboration with IMEDEA, the Institute of Marine Sciences (ICM-CSIC), the University of Cadiz, Medsea Partners, the Spanish Oceanographic Institute, and the GEOTRACES international programme, has just returned from a research cruise to survey the current state of the Mediterranean Sea in relation to the high concentration of CO2 in the atmosphere, and also to detect other anthropogenic impacts on the sea, such as the distribution of microplastics. The team collected samples of both surface and deep seawater to measure concentrations of CO2 and other chemical compounds in the water, and their impact on certain organisms and biogeochemical processes.

The sampling included aerosol collection, plankton tows and detailed water column and sediment samplings, in order to analyse natural and artificial radioactive isotopes and trace elements dissolved in the seawater, within the GEOTRACES project, represented in Spain by Jordi Garcia Orellana, a UAB lecturer. Four sea robots carrying miniature sensors were launched at different locations in the Mediterranean to continue collecting data (on water temperature, nutrients, salinity, chlorophyll, etc.) over the coming months.
