The biogeochemical provinces of the Southern Ocean, as defined by Treguer andjacques (1992), are the Polar Front Zone, the Permanently Open Ocean Zone, the Marginal and Seasonal Ice Zones, and the Coastal and Continental Shelf Zone (Fig. 12.1). Note that the Marginal Ice Zone is a seaward subzone of the Seasonal Ice Zone delimited by the recent melting of ice, a seasonally migrating band of recendy exposed surface waters within the Seasonal Ice Zone (Moore et ah, 2000). The...

Ice is a key attribute linked to cycles of primary productivity on continental shelves. Marginal ice zones (MIZ) are some of the most dynamic areas in the world s oceans with large seasonal and inter-annual fluctuations in ice cover and ice transport. These are unique habitats with specific communities dependent upon the physicochemical structure of the ice (Thomas Dieckmann, 2002).

Anyone who has traveled to a marginal ice zone, where sea ice meets the open ocean, is struck by a particular contrast with the central ice pack the tremendous abundance of animal life. The food chain, at the crudest level, is obvious. There is more light in the water column and biological blooms are frequent. Fish feed on tiiese.
