The global estimate of the soil organic carbon accumulation rate in SCEs ranged
from 20 to 1,017 Tg C year
–1
, with a mean value of 205 Tg C year
–1
, which is comparable to previous reports (Nellemann et al. 2009; Pendleton et al. 2012). Estuaries
(mean, 81 Tg C year
–1
) were major contributors to the total accumulation rate in
SCEs, as reported previously (Nellemann et al. 2009).
To the best of our knowledge, this work provides the first global estimate of CO 2
exchange rates in SCEs. The estimated rates ranged from –8438 to 6302 Tg C year
–1
,
with a mean of –1666 Tg C year
–1
(negative value: net uptake of atmospheric CO 2 ).
