Physiography, hypsometry, and volume of the Arctic Ocean and its constituent seas

Researchers have for long been interested in the earth's physiographic provinces and hypsometry – the distribution of surface area at various elevations of land and depths of ocean. Based on International Bathymetric Chart of the Arctic Ocean (IBCAO) physiographic provinces have been classified and hypsometry and volume of the Arctic Ocean and its constituent seas have been calculated in this research.

The used methods and scientific results are described in Jakobsson (2002) and Jakobsson et al., (2003). The physiographic classification was based on an evaluation of seafloor gradients contained in a slope model that was derived from the IBCAO digital bathymetric model. The areas of the provinces so classified are individually calculated, and their morphologies are subsequently discussed in the context of the geologic evolution of the Arctic Ocean Basin.


“Slope model of the Arctic Ocean classified after three slope intervals. This model helped to derive the first order classification of physiographic provinces (See Jakobsson et al, 2003)."


“First order physiographic provinces of the Arctic Ocean defined using derived bottom slope values from the IBCAO model and or from other criteria.”

“Calculated proportion of Arctic Ocean classified physiographic provinces (Jakobsson et al., 2003).“
