抽象的。分析了三种珊瑚群落中Cd/Ca和Mn/Ca的比值（Porites panamensis（1967-1989），Pavona clivosa（1967-1989）和孔雀草（1979-1989）），以评估厄尔尼诺-南方涛动（ENSO）事件在热带北太平洋东部（ETNP）引起的海洋变化。珊瑚Cd/Ca和Mn/Ca比值的年际变化表明，在珊瑚骨架中的Cd和Mn的掺入受到ENSO条件的影响，但对每种金属的响应是由不同的过程控制。在ENSO年份，Mn/Ca比值显著升高（p <0.05）。
Abstract. We analyzed the trace element ratios Cd/Ca and Mn/Ca in three coral colonies (Porites panamensis (1967–1989), Pavona clivosa (1967–1989) and Pavona gigantea (1979–1989)) from Cabo Pulmo reef, Southern Gulf of California, Mexico, to assess the oceanographic changes caused by El Nino – Southern Oscillation (ENSO) events in the Eastern Tropical North Pacific (ETNP). Interannual variations in the coral Cd/Ca and Mn/Ca ratios showed clear evidence that incorporation of Cd and Mn in the coral skeleton was influenced by ENSO conditions, but the response for each metal was controlled by different processes. The Mn/Ca ratios were significantly higher during ENSO years (p
