Upwelling along the western coast of the Iberian Peninsula: dependence of trends on fitting strategy
We investigated upwelling variability along the western coast of the Iberian Peninsula for the period 1948−2009 by means of wind data extracted from the NCEP/NCAR reanalysis project. According to most previous studies, a remarkable weakening in upwelling intensity has been observed in the area. However, the observed linear trends are highly dependent on the length of the series. Here we show ho...
متن کاملUpwelling influence on the Galician coast: silicate in shelf water and underlying surface sediments
-Local characteristics in the upwelling of Galicia (NW Iberian Peninsula) are studied in terms of dissolved silicate patterns in the seawater column and opal distribution in the sediments. Freshwater input, upwelling, remineralization and sedimentation are considered. The freshwater silicate input is not important during the upwelling season. Upwelling is the main process controlling silicate b...
متن کاملDistribution of surface carbon dioxide and air-sea exchange in the upwelling system off the Galician coast
[1] Data on the distribution of the partial pressure of CO2 (pCO2) were obtained during six cruises off the Galician coast, a region characterized by a seasonal upwelling. The values of pCO2 over the continental shelf are highly variable and range between 265 and 415 matm during the upwelling season and between 315 and 345 matm during the downwelling season. Both the continental shelf and off-s...
متن کاملModeling an unusual upwelling event observed along the western Adriatic coast in the summer of 2003
The goal of this research was to simulate and analyze the response of the Western Adriatic Current (WAC) to an abnormal event that occurred in the Adriatic Sea in mid-summer of 2003. At this time, a combination of extremely low discharge from the Po River and from other northwestern rivers caused by the prolonged dry season and the dominant Sirocco wind produced an ðunusual’ upwelling and cause...
متن کاملEvolution of extreme Total Water Levels along the northern coast of the Iberian Peninsula
This paper assesses the evolution of storminess along the northern coast of the Iberian Peninsula through the calculation of extreme (1%) Total Water Levels (eTWL) on both observed (tide gauge and buoy data) and hindcasted (SIMAR-44) data. Those events were first identified and then characterized in terms of oceanographic parameters and atmospheric circulation features. Additionally, an analysi...
