“…Additional data have shown that the relationship between pCO 2 and salinity in the Amazon is remarkably stable on a seasonal basis (Lefèvre et al 2010). Seasonal CO 2 distributions and air-water fluxes in inner estuaries and river plumes have also been reported for the Changjiang River (Wang et al 2000;Chen et al 2008;Chou et al 2009b;Zhai and Dai 2009) and preliminarily for the Mississippi River (Cai 2003;Dagg et al 2005; Lohrenz et al 2010;Huang 2013). However, the aforementioned information has not been properly incorporated in the global synthesis shown in Table 7.1; an initial attempt is made here to address this problem.…”

“…The East China Sea has been well studied with respect to the inorganic carbon system (e.g. Tsunogai et al, 1997;Chen and Wang, 1999;Tsunogai et al, 1999;Wang et al, 2000). The East China Sea absorbs roughly twice as much CO 2 as is emitted annually from the Scotian Shelf region.…”

Air-Sea CO<sub>2</sub> fluxes on the Scotian Shelf: seasonal to multi-annual variability

Abstract.We develop an algorithm to compute pCO 2 in the Scotian Shelf region (NW Atlantic) from satellite-based estimates of chlorophyll-a concentration, sea-surface temperature, and observed wind speed. This algorithm is based on a high-resolution time-series of pCO 2 observations from an autonomous mooring. There is a gradient in the air-sea CO 2 flux between the northeastern Cabot Strait region which acts as a net sink of CO 2 with an annual uptake of 0.50 to 1.00 mol C m −2 yr −1 , and the southwestern Gulf of Maine region which acts as a source ranging from −0.80 to −2.50 mol C m −2 yr −1 . There is a decline, or a negative trend, in the air-sea pCO 2 gradient of 23 µatm over the decade, which can be explained by a cooling of 1.3 • C over the same period. Regional conditions govern spatial, seasonal, and interannual variability on the Scotian Shelf, while multi-annual trends appear to be influenced by larger scale processes.

“…Although significant CO 2 sinks were observed certainly in the ECS shelf using sea-air pCO 2 difference and it is generally considered that the ECS is an annual net carbon sink, controversies still exist about whether on ECS is a source or sink of carbon in a given season and the ability of the ECS to absorb atmospheric CO 2 (Tsunogai et al, 1997;Zhang et al, 1997;Peng et al, 1999;Tsunogai et al, 1999;Wang et al, 2000;Hu and Yang, 2001;Song, 2004). Except for the fact that they used different calculation methods, which can cause difference to some extents, the difference in the studied time and area is another reason leading to the controversies, owing to the fact that spatio-temporal diversity is an important characteristic for pCO 2 distribution in surface seawaters.…”

Partial pressure of CO 2 (pCO 2 ) was investigated in the Changjiang (Yangtze River) Estuary, Hangzhou Bay and their adjacent areas during a cruise in August 2004, China. The data show that pCO 2 in surface waters of the studied area was higher than that in the atmosphere with only exception of a patch east of Zhoushan Archipelago. The pCO 2 varied from 168 to 2 264 μatm, which fell in the low range compared with those of other estuaries in the world. The calculated sea-air CO 2 fluxes decreased offshore and varied from −10.0 to 88.1 mmol m -2 d -1 in average of 24.4 ± 16.5 mmol m -2 d -1 . Although the area studied was estimated only 2 × 10 4 km 2 , it emitted (5.9 ± 4.0) × 10 3 tons of carbon to the atmosphere every day. The estuaries and their plumes must be further studied for better understanding the role of coastal seas playing in the global oceanic carbon cycle.
