Icebergs were counted during SIBEX-Phase II, 1985, according to instructions of the Norsk Polar Research Institute aboard the M/N ALCAZAR. A total of 196 hours of iceberg counts revealed a larger concentration of these on the SE part of the Bransfield Strait. These results agree with the physical oceanographic pattern of that Antarctic sector; but more observations are needed to conclude better causes of their drift and aggregations.
Se presentan conteos de témpanos a la deriva observados durante SIBEX-Pase II, 1985, a bordo de la M/N "ALCAZAR". Los controles se guiaron por instrucciones distribuidas por el Instituto de Investigaciones Polares de Noruega. La mayor concentración de témpanos se observó en el tercio SE del estrecho Bransfield, coincidiendo con la oceanografía física del lugar. Es necesario realizar mayor cantidad de controles para obtener conclusiones mas valederas sobre deriva y agrupamientos de hielos.
