Progress in Oceanography Biogeochemistry of surface sediments off Concepción ( 36 S ) , Chile : El Niño vs . non - El Niño conditions
We compared the signals of several water column properties (upwelling intensity, sea level anomaly, temperature, nutrients, dissolved oxygen, chlorophyll-a, and surface sediments) of the continental shelf off Concepción (36 S) during the 1997–1998 El Niño with those of a normal year (2002–2003). We found that the primary hydrographic effect of El Niño 1997–1998 was a reduction in the input of n...
متن کاملThe Predictability of El Nino the 1997/98 El Nino
The Southern Oscillation, a natural mode of oscillation of the coupled ocean-atmosphere system, at times appears to be self-sustaining and hence relatively easy to predict. The 1980s seem to have been such a period; El Nino of 1982183 was the start of two complete cycles of the Southern Oscillation. At other times the oscillation seems to be a damped mode that is present for a cycle at most, af...
متن کاملThe impact of sea level data assimilation on the Lamont model prediction of the 1997 / 98 El Niño
Assimilating the sea level data from tropical Pacific tide gauges greatly improved the Lamont model prediction of the 1997/98 El Niño while retaining its overall performance during the past few decades. The implication is that the Lamont forecast system is limited by the observational data used for initialization probably probably as much as by its simplified model physics. The sea level measur...

متن کاملMeiofauna and sedimentary organic matter off Central Chile: response to changes caused by the 1997–1998 El Niño
− Quantitative surveys of metazoan meiofauna were carried out in an upwelling region off Central Chile (36oS). During May 1997 and May 1998, coinciding with the onset and end of El Niño, five benthic stations (respectively 27, 34, 64, 88, and 120 m depth), from the middle of Concepción Bay to the edge of the adjacent continental shelf, were sampled. The sedimentary organic matter biopolymeric f...
