Human-induced eutrophication is minimised, especially adverse effects thereof, such as losses in biodiversity, ecosystem degradation, harmful algae blooms and oxygen deficiency in bottom waters

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.

Further, this marine mammal activity can probably counteract stagnant, nutrient-depleted, " stratified" surface water conditions that tend to invite the growth of harmful algae blooms, which are another growing concern.

Since its founding, ELA has been a global leader in conducting full ecosystem experiments, which have been critical to understanding harmful acid rain, algae blooms, methyl mercury and in shaping public policy.
