Spatio-temporal variability of sea-air CO2 flux
Abstract
Spatio-temporal characteristics of the resulting monthly sea-air CO2 flux for 4-degree latitude zones of the World Ocean for the period of 1980-2010 are considered. The regularities of the annual and semi-annual cycle of CO2 flux in different lattitude zones and the whole ocean are determined. Trend analysis showed that in most latitudinal zones they are significant. Distinct intensification of the carbon dioxide exchange between the ocean and athmosphere is found. The global CO2 flux has a positive trend and shows a slight derease (-0.005 Pg C per year). It is shown that up to 1997 the global air-sea CO2 flux has been increasing, and then it began to decrease.
