| 1 | Short-and Long-Term Response of Phytoplankton to ENSO in Prydz Bay, Antarctica: Evidences from Field Measurements, Remote Sensing Data and Stratigraphic Biomarker Records显示文摘The study provides one of the first lines of evidence showing linkages between Antarctic phytoplankton abundance and composition in response to ENSO, based on historical reconstruction of sediment biomarkers. In addition to sediment biomarkers, field measured and remote sensing data of phytoplankton abundance were also recorded from Prydz Bay, Eastern Antarctica. Community structure of field measured phytoplankton showed significant El Nino/La Nina-related succession during 1990 to 2002. In general, the number of algae species decreased during El Nino and La Nina years compared to normal years. Austral summer monthly variation of remotely sensed chlorophyll-a(Chl-a), particulate organic carbon(POC), and sea surface temperature(SST) indicated that ENSO impacted the timing of phytoplankton blooms during 2007 to 2011. Phytoplankton blooms(indicated by Chl-a and POC) preceded the increases in SST during El Nino years, and lagged behind the SST increases during La Nina years. Stratigraphic record of marine sedimentary lipid(brassicasterol, dinosterol and alkenones) biomarkers inferred that the proportions of different algae(diatoms, dinoflagellates and haptophytes) changed significantly between El Nino and La Nina events. The relative proportion of diatoms increased, with that of dinoflagellates being decreased during El Nino years, while it was reversed during La Nina years. | ZHAO Jun Hans-Ulrich Peter ZHANG Haisheng HAN Zhengbing HU Chuanyu YU Peisong LU Bing Thomas S.Bianchi | 2014 | Journal of Ocean University of China2014，13，3： | 0 |
