Ballast water transferred by vessels is recognized by the United Nations as a prominent vector for transfer of harmful aquatic organisms and pathogens across natural barriers.
The volume of Ballast Water discharged in the Adriatic Sea ports is above 10 million tons per year.
In the whole Adriatic region 190 non-indigenous species were registred by Zenetos et al. (2010).
The BALMAS project integrates all necessary activities to enable a long-term, environmentally efficient and financially and maritime transport sustainable implementation of ballast water management measures in the Adriatic.
Within BALMAS we will establish a common cross-border system linking all Adriatic research, experts and national responsible authorities in order to avoid the unwanted risks to the environment and humans from the transfer of harmful aquatic organisms and pathogens through the control and management of ships’ ballast waters and sediments.
Four seasonal campaigns are sheduled in 2014 at six sampling sites within the Port Authority of Trieste and at a control site offshore the Marine Park of Miramare according to the Port Baseline Survey (PBS) protocols in the frame of the Monitoring Programme - BALMAS WP 5.2.
On 23rd September 2014, the 3rd BALMAS PBS sampling of the water column was held by OGS (National Institute of Oceanography and Experimental Geophysics) in the Port of Trieste with the partnership of the local Coast Guard.
Environmental and biotic parameters were sampled at the surface and bottom layer.
Environmental variables such as temperature and salinity were measured using a multiparametric probe, water samples taken from the optic layers by means of Niskin bottles in order to determine both oxygen nutrients and Chlorophyll whereas transparency determined by means of the Secchi disk.
Phytoplankton was horizontally and vertically towed (bottom vs surface) by means of a planktonic net (20 µm mesh size) and cells, kept alive and stored immediately on board according to standard protocols. Mesozooplankton was collected from the bottom to the surface by means of a WP2 net (200 µm mesh size) and stored immediately.
