Integrated GIS-based estimate of plankton and benthos biomasses in the Barents Sea
2008
Novikov, M. A.
The quantitative characteristics and biomass distribution of plankton and benthos in the Southern Barents Sea are estimated by using geographic information system technologies. A database from a computer atlas of the Barents Sea is used to calculate the summary, total, and mean biomass. The quantitative parameters of plankton are estimated via creating a synthetic digital map, reflecting the joint distribution of phytoplankton, meso-and macrozooplankton in a raster format. The total and mean biomass of benthos is calculated via digitizing published cartographic data with subsequent processing of the digital cartogram. The obtained results are compared with estimates made earlier by other researchers. Generalizing characteristics, such as biomass production, P/B-coefficient, and ecological efficiency are calculated.
