Abstract
The functional characteristics of the biosphere are reflected in its binominale frame: continents – oceanic basins. The river-basin land, on the one hand, and pericontinental oceanic waters on the other hand, are the main components of the homeostatic mechanism of the biosphere. In the Archean and Early-Middle Proterozoic, seawater biofiltration did not exist. In the Late Proterozoic and part of the Early Paleozoic, biofiltration started to develop and the oceans have become the main heat-engine of the Earth. Today, the maximum concentration of productive phytoplankton and zooplankton – filter bio-systems – is in the pericontinental oceanic zones. This is a response to the maximal flow of nutrients from the land carried mainly with river flow. This is the main signal of a direct link between terrestrial and oceanic ecosystems. The feedback is the atmospheric precipitation induced by heat and moisture flows and carried from the oceans to the land within its primary river-basin part. These links are experiencing anthropogenic destabilization due to some misplaced priorities of sustainable development and its implementation.
Highlights
The influence of organic life on the global dynamics was discussed in the works of J
Lisitzin [2004] “Primary Production of the Ocean” and “Zooplankton Systems Filtering Capacity” show: a) the highest primary productivity of phytoplankton and zooplankton systems filtering capacity are associated with waters adjacent to the continents; b) the lowest primary productivity of phytoplankton and zooplankton systems filtering capacity are associated with the oceanic areas in tropical zones, isolated from any major land fragments and with an extreme deficit of meteoric precipitation
The functional characteristics of the biosphere are manifested in its two-element organization and in the major functional components of the homeostatic mechanism, among which are the river-basin land and the pericontinental production-biofiltration oceanic margin
Summary
The influence of organic life on the global dynamics was discussed in the works of J. Deforestation of catchment areas and establishment of meadows, arable land, and settlements is accompanied by rapid snowmelt, increasing surface runoff, abnormally high and rapid floods, reduced groundwater recharge and their runoff, increase of sheet and gully erosion and sediment discharge to hydrographic network, and transformation of small river valleys into gulches, which represents a response to a sharp decrease of the normal rate of their discharge in summer.
