ABSTRACT
This study simulates the spillage of 1460 metric tons of oil that occurred in January 2022 off La Pampilla Refinery, in central Perú. The oil slick was predominantly displaced northward along the coastline, driven by prevailing currents and winds in the region. The weathering analysis revealed that the removal of oil was mainly due to evaporation (28%) and beaching processes (70%) within 96 h after the initial release. The coastal areas spanning from Ventanilla to Punta Chancay experienced significant impacts from the oil spill, representing 96% of the total affected coastal extent. Specifically, Ventanilla and Santa Rosa Beaches and the National Reserve System of Islands were heavily impacted during the first 24 h, while the surroundings of Ancón Bay, Aucallama and Pasamayo beaches were affected after two days. This modeling case study provides valuable insights into the fate and transport of the Repsol oil spill.

En el presente trabajo se analizan un total de 1339 ejemplares de Octopus mimus Gould, 1852, procedentes de muestreos mensuales realizados en las localidades de Ilo durante el año 1993, Pucusana durante 1997 y en el Callao durante 1998. La relación talla-peso de los ejemplares de Ilo y Callao mostraron un crecimiento alométrico para ambos sexos. Las hembras alcanzan la talla de desove a los 14.3 cm de longitud del manto. Esta talla fue utilizada para estimar un peso mínimo de captura de 1 kg. La dieta es variable y consiste en crustáceos, moluscos, peces y equinodermos. Las capturas fueron 6 veces más altas durante El Niño 1997-1998 que El Niño 1982-1983. La presente información es comparada y discutida con los datos de Chile.
