ESTIMATION OF ONSHORE-OFFSHORE TRASPORT OFF CENTRAL CHILE BY MEANS OF MAXIMUN CROSS-CORRELATION USING SATELLITE DERIVED SST Gayana
Navarro,Eduardo; Schneider,Wolfgang; Letelier,Jaime.
Between December 2001 and February 2002, NOAA-AVHRR images were obtained twice a day for the region between 30-40S and 70-80W. Within the cloud free areas, sea surface temperature was calculated according to standard split window algorithms. The geo-referenced horizontal resolution for each SST-pixel resulted in 2 km, in east-west and north-south direction. All pairs of images were analyzed with respect to advective surface velocity by means of Maximum Cross-Correlation. Maximum Cross-Correlations exceeding the predetermined significance level of cross correlation were accepted. From all pairs of comparison monthly advective velocity maps (and SST maps) were constructed and separated in a coastal and offshore band. Coastal upwelling was observed along the...

The Perú-Chile undercurrent and the oxigen minimum zone variability off central Chile Gayana
Hormazábal,Samuel; Shaffer,Gary; Silva,Nelson; Navarro,Eduardo.
Ten years of continuous current meter recordings near the core of the Peru-Chile Undercurrent (PCU) over the continental slope at 30°S off Chile, local and equatorial wind stress data, and monthly oceanographic sections off Valparaíso (33°S) are used to study the variability of the PCU and the Oxygen Minimum Zone (OMZ) off Chile. The physics that governs the PCU variability differs for intraseasonal periods and for longer periods: Coastal trapped waves dominate the intraseasonal band whereas Rossby waves dominate for periods greater than about 120 days. Semiannual and annual period fluctuations can largely be explained by Rossby waves forced by equatorial Kelvin waves and local winds. Seasonal variations in the PCU are strongly modulated over El Niño/La...

Nototriche Carabayensis (Malvaceae), una especie nueva de los Andes de Perú Darwiniana
Gonzáles,Paúl; Navarro,Eduardo; Chanco,Magda; Cano,Asunción.
Se describe e ilustra a Nototriche carabayensis (Malvaceae), una nueva especie de los Andes del sur de Perú. Nototriche carabayensis se relaciona con N. cupuliforme, N. antoniana y N. peruviana por presentar una estructura a manera de corona en la base del tubo estaminal; se distingue por la corola blanca con venas rojo-violáceas, los nectarios deltoideos y 11 estigmas. Se incluyen la descripción, ilustración y fotos de la especie nueva, y una clave de las especies peruvianas con corona.
