Abstract:

The Bering Sea, in the Pacific sector of the Arctic Ocean, represents a typical area of transition from a
sub-Arctic ecosystem to an Arctic ecosystem. The study of its CO2 sources and sinks will provide an important
reference for high-latitude continental margin regions. Within the context of global warming, the Bering
Sea is undergoing climatic and environmental changes. The effects of these changes on both the CO2 sources
and sinks and the related biogeochemical processes of the area are considerable. This paper summarizes the
CO2 sources and sinks and their control mechanisms in the Bering Sea, describes the tendencies of those
CO2 sources and sinks, and predicts their future prospects. Previous studies have argued that the Bering Sea
acts as a sink for atmospheric CO2 but the results have been notably varied. Recent studies have reported that
the CO2 sinks on the Bering shelf and in the entire Bering Sea are about −6.81×1012g C·a-1 and −34×1012g
C·a−1, respectively. However, if climatic and environmental changes continue to intensify in the future, conditions
that could result in a decrease or in an increase in the magnitude of the CO2 sink might exist simultaneously.
Therefore, it remains inconclusive whether the function of the Bering Sea as a carbon sink will be
enhanced or weakened in the future.
