Black dots show dead zones of unknown size. The size and number of marine dead zones—areas where the deep water is so low in dissolved oxygen that sea creatures cannot survive (except for some specialized bacteria)—have grown in the past half-century. [1] Dead zones are hypoxic (low-oxygen) areas in the world's oceans and large lakes.
The exclusive economic zone of Canada is the area of the sea in which Canada has special rights regarding the exploration and use of marine resources, as prescribed by the 1982 United Nations Convention on the Law of the Sea. [1] Canada's exclusive economic zone (EEZ) is the 7th-largest in the world. [2]
Red circles show the location and size of many dead zones (in 2008). Black dots show dead zones of unknown size. The size and number of marine dead zones—areas where the deep water is so low in dissolved oxygen that sea creatures cannot survive (except for some specialized bacteria)—have grown in the past half-century.

The Atlantic Ocean is teeming with life, but for the first time researchers have discovered dead zones in these waters - areas low in both oxygen and salinity - off the coast of Africa. Fish can't ...
This new ecozone map includes 18 terrestrial, 12 marine and 1 freshwater ecozone, the latter two of which were derived from the marine bioregions outlined by Fisheries and Oceans Canada in 2009. [8] [6] This comprehensive framework is currently in use by Environment and Climate Change Canada to determine protected area coverage of Canada's ...
This zone experiences the warmest and wettest climate in Canada. [2] The lower Georgia Strait may receive as little as 600 mm of annual precipitation, but other areas in this zone receive as much as 3,000 mm. [3] Moderated by the influence of the Pacific Ocean, the zone experiences mild winters and cool summers. [5]
A 'dead zone' off the Gulf coast is larger than NOAA predicted. The massive area poses danger to marine life, and recovery could take decades. A 'dead zone' is growing in the Gulf of Mexico.
The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy. The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins.
