The oceanic sink for anthropogenic CO2 from 1994 to 2007
Overview & Synopsis
We quantify the oceanic sink for anthropogenic CO2 over the period 1994 to 24 2007 using observations from the global repeat hydrography program and 25 contrasting them to observations from the 1990s. Using a linear regression-based 26 method, we find a global increase in the anthropogenic CO2 inventory of 33±4 Pg 27 C between 1994 to 2007. This is equivalent to an average uptake rate of 2.5±0.3 28 Pg C yr-1 and represents 30±4 % of the global anthropogenic CO2 emissions over 29 this period. While this global ocean sink estimate is consistent with the 30 expectation of the ocean uptake having increased in proportion to the rise in 31 atmospheric CO2, substantial regional differences in storage rate are found, 32 likely owing to climate variability driven changes in ocean circulation. 33
