    Visualizing the Census of Marine Life
  • Log in

The Census of Marine Life was a global network of researchers in more than 80 nations engaged in a 10-year scientific initiative to assess and explain the diversity, distribution, and abundance of life in the oceans.  The world's first comprehensive census of the past, present, and future of life in the oceans was released in October 2010.


Longhurst Biogeographical Provinces

This dataset represents a partition of the world oceans into provinces as defined by Longhurst (1995; 1998; 2006)

Longhurst Biogeographical Provinces

The dataset represents the initial static boundaries developed at the Bedford Institute of Oceanography, Canada. Note that the boundaries of these provinces are not fixed in time and space, but are dynamic and move under seasonal and interannual changes in physical forcing. At the first level of reduction, Longhurst recognised four principal biomes (also referred to as domains in earlier publications): the Polar Biome, the Westerlies Biome, the Trade-Winds Biome, and the Coastal Boundary Zone Biome. These four Biomes are recognisable in every major ocean basin. At the next level of reduction, the ocean basins are partitioned into provinces, roughly ten for each basin.
