Gaia Paradigm: A Biotic Origin Of The Polar Sunrise Arctic Bromine   Explosion
  The main attention is given to discussion of the natural causes and regularities of the Arctic bromine pollution. We make notice of marine microbial organisms and their metabolism as a prime driving force for the elemental biogeochemical cycles. One of the important conclusions of this study is on similarity between ocean bromine concentrating as by-product of the marine microbial activities and nitrogen fixation by soil bacteria. In both cases, microbial organisms and their food webs maintain the sustainability of the superficial environments throughout the geological ages of the biotic Earth. Phenomenology of bromine explosion points on synchronization of the biogeochemical processing upon the solar factor. Spatial-temporal extent and statistical properties of the Arctic BrO cloud make the bromine explosion phenomena an exceptionally valuable for modeling. In our analysis of of the interannual (Solar Cycle 23) variability of the BrO cloud, we rely on on the processed from GOME satellite data and on the ground observations. Sustainability of the earth superficial environments is impossible without ozone-oxygen transformations. Bromine pollution activate catalytic depletion of ozone, which leads to the intensification of oxygen fluxes and atmosphere-ocean exchange and to the stimulation of the seasonal production of the superficial Northern Hemisphere's biota. The biotic bromine explosion illustrates the major concepts of Gaia hypothesis and yields on the foundational principle of multiple unity of the Earth's life and planetary operations.
