| 英文摘要: | To study effects of extreme weather events (EWEs, e.g., dust storm and typhoon) on the export of particulate organic carbon (POC) measured by a floating sediment trap in the oligotrophic ocean, eight sea-going expeditions were conducted in the oligotrophic northwest Pacific (NWP) in 2007 and 2008, covering all four seasons and the passage of several EWEs. Results of year-round field observations demonstrate that the POC export fluxes in the oligotrophic NWP did not exhibit apparent seasonal variations yielding an average flux of 36.9 ± 5.8 mg-C m-2 d-1 without EWE effects. With EWE effects, however, the POC export flux (51.7 ± 13.2 mg-C m -2 d-1) showed an approximately 40% increase compared to the average flux measured without EWE effects. These results suggest that EWEs can trigger elevated POC export from the euphotic zone in the oligotrophic ocean. Key Points Extreme weather events can enhance POC export in the oligotrophic ocean Concentration of Chl a is not enhanced several days after extreme weather POC fluxes without extreme weather effects are similar in four seasons ©2013.
