Unlike other semi-enclosed seas such as the Baltic or the Black Sea, a large part of the Mediterranean Sea remains High Seas waters, thereby raising specific governance issues.

I ask this committee to urge the minister to perform his mandate under the Oceans Act to promote the " understanding of oceans, ocean processes, marine resources and marine ecosystems" by setting the terms of reference for new research, by asking DFO Science to do the following: first, to calculate and report on the current value of ecosystem services now provided by the grey seal herd, particularly in terms of enhanced primary productivity, and the model for that has already been done in the Gulf of Maine; second, to calculate and report on the projected plankton response to any grey seal cull, including the knock-on impact on plankton-dependent species; third, to develop new population and ecosystem models incorporating the positive pa ...[+++]thways of effect between marine mammals and ecosystem primary productivity; fourth, to assess and report on the current risk of the occurrence of harmful algae blooms associated with stagnant surface water conditions, especially inside the Gulf of St. Lawrence, and offer science advice on the potential value of the presence and activity of the grey seal herd in mitigating this potential health hazard; and, fifth, to assess and report on the potential effectiveness of air-breathing marine predators in limiting " dead zones" in semi-enclosed waterways such as the Gulf of St. Lawrence.

(3) The Baltic Sea ecosystem, a semi-enclosed European inland sea, is one of the world's largest brackish water bodies and has been seriously affected by many natural and human-caused pressures, such as pollution from dumped chemical weapons, for example war gases, dating back to the Second World War and from heavy metal compounds, organic substances, radioactive material, and heating oil and petroleum spills.

Permanent separation of water strata, minimal reaction with the sea bottom, restricted flow patterns resulting from semi-enclosed bays and estuaries and shallow bowl shapes in the sea bottom all favour the isolation of bottom water masses and therefore limit reoxygenation.
