Abstract

Abstract

The sea surface temperature(SST), salinity(SSS), dissolved oxygen (DO), chlorophyll a(Chl a) and surface partial pressure of carbon dioxide(pCO₂) was determined by underway measurement system in the Qiongzhou Strait in summer 2011 and 2014, and the spatiotemporal variations of pCO₂ were analyzed and its control factors were explained. The averages of pCO₂in surface sea water were (516±29) μatm and (533±15) μatm, sea-air CO₂ fluxes were (8.4±1.7) mmol/(m²·d) and (4.5±0.4) mmol/(m²·d) in summer 2011 and 2014, the Qiongzhou Strait acted as strong atmospheric CO₂ source and was more higher than the adjacent and similar sea areas. The upwelling forced the CO₂-enriched subsurface water to intrude the surface water and elevated pCO₂in the east mouth, also promoted biological productivity and absorbed CO₂from sea water, and also made the pCO₂drop and DO rise sharply in the vicinity of west mouth in summer 2011. The upwelling was weak in east mouth and vertical mixing was strong along ship-track in summer 2014, the distributions of pCO₂and DO were obviously different from that in summer 2011. Narrow channel effect was significant in the middle of Qiongzhou Strait, high water transportation speed with strong mixing resulted in weak photosynthetic activity, they altogether maintained high pCO₂ in summer 2011 and 2014.
- the Qiongzhou Strait,
