Riascos Koen Van Waerebeek Ciencias de la Tierra seasonality neritic waters upwelling center Balaenoptera physalus In this paper we report the apparently seasonal presence of fin whales in Mejillones Bay (23°S), in northern Chile. We compiled a total of 19 sightings representing 95 whales, including 2 mother-calf pairs, between July and October 2006- 2014. We observed groups of 1-10 individuals (mean 5 ± 2.7 ind.) principally in nearshore waters, 30-1000 m off the southwestern tip of Mejillones Bay in austral winter/spring. Fin whales came close to, and potentially overlapped with, the main port access routes of large cargo vessels. Information from real-time monitoring of whale presence relayed to Port Authorities is suggested as to avoid collisions. 2015 artículo científico 0717-3326 https://www.redalyc.org/articulo.oa?id=47941332017 en http://www.redalyc.org/revista.oa?id=479 Revista de Biología Marina y Oceanografía application/pdf Universidad de Valparaíso Revista de Biología Marina y Oceanografía (Chile) Num.2 Vol.50 |
