Iosu Madariaga: “la pérdida de biodiversidad y el cambio climático son dos grandes retos de administraciones y comunidad científica en el golfo de Bizkaia”

22 de junio de 2016
  • El Viceconsejero de Medio Ambiente del Gobierno Vasco participa en el XV International Symposium on Oceanography of the Bay of Biscay
  • Organizado por el Departamento de Biología Vegetal y Ecología de la Universidad del País Vasco
  • “El Golfo de Bizkaia, al igual que otros entornos similares, se enfrenta a un calentamiento del agua de entre 1,5 y 3,5ºC y a una subida del nivel del mar de entre 29 y 49 centímetros para finales de siglo”

El Viceconsejero de Medio Ambiente del Gobierno Vasco, Iosu Madariaga, ha indicado esta mañana en la apertura del XV International Symposium on Oceanography of the Bay of Biscay organizado por el Departamento de Biología Vegetal y Ecología de la Universidad del País Vasco “que dos de los retos ambientales a los que los gobiernos y la comunidad científica de todo el planeta están intentado dar respuesta son la pérdida de biodiversidad y al cambio climático, también en el golfo de Bizkaia”. 

“El Golfo de Bizkaia, al igual que otros entornos similares, se enfrenta a un calentamiento del agua de entre 1,5 y 3,5ºC y a una subida del nivel del mar de entre 29 y 49 centímetros para finales de siglo, además de un previsible aumento del número de temporales” ha señalado Madariaga en la Bizkaia Aretoa de la EHU UPV en Bilbao. 

A juicio de Madariaga “Euskadi cuenta con instrumentos de planificación ambiental para mitigar estos efectos, sobreponernos a situaciones extremas y cumplir los compromisos ambientales que nos hemos marcado. El más importante de todos ellos es el Programa Marco Ambiental 2020. De este marzo se derivan la ‘Estrategia de Cambio Climático del País Vasco 2050’, aprobada el pasado año, la Estrategia de Geodiversidad 2020, y la Estrategia de Biodiversidad 2030, cuyo proceso de participación pública acaba de finalizar y cuya aprobación está próxima”. 

El XV Simposio Internacional de Oceanografía del Golfo de Bizkaia (ISOBAY 15) se celebra en Bilbao, del 22 de junio a la 24 de junio de 2016. Este encuentro bienal lo protagonizan las personas  investigadoras que realizan estudios sobre el Golfo de Bizkaia, desde mar abierto a las zonas costeras y  estuarios, y que disponen de la oportunidad de presentar sus trabajos. Con un carácter multidisciplinar su objetivo es una contribución significativa hacia un conocimiento integrado del Golfo de Bizkaia.

 El tema principal de esta 15ª edición se centra en el cambio de los ecosistemas: lo natural frente a los efectos antropogénicos. El programa científico cubrirá los siguientes temas:   1. Oceanografía Física   2. Relaciones clima-océano   3. Geología, erosión, transporte y sedimentación   4. Los ciclos biogeoquímicos   5. La biodiversidad, estructura y funcionamiento del ecosistema   6. Pesca y Acuicultura   7. Los efectos antropogénicos, evaluación de calidad y la gestión de los ecosistemas



The XV International Symposium on Oceanography of the Bay of Biscay (ISOBAY 15) will be held in Bilbao, from June 22 to June 24, 2016.


This biennial symposium is aimed to offer researchers conducting studies on the Bay of Biscay, from open ocean to coastal and estuarine zones, the opportunity to present and discuss their most updated works. With a multidisciplinary nature the goal is to make a significant contribution towards an integrated knowledge of the Bay of Biscay.


The main theme of this 15th edition is Changing Ecosystems: Natural versus Anthropogenic Effects and the scientific programme will cover the following topics:

 1. Physical Oceanography

 2. Climate-ocean relations

 3. Geology, erosion, transport and sedimentation

 4. Biogeochemical cycles

 5. Biodiversity, ecosystem structure and functioning

 6. Fisheries and Aquaculture

 7. Anthropogenic effects, quality assessment and ecosystem management


ISOBAY 15 can be an excellent occasion to meet and network with many other researchers interested in the study of the Bay of Biscay, both for early career researchers, as well as for established scientists. It can be a good opportunity also to visit Bilbao, a city which has undergone an internationally recognized urban transformation, becoming a modern and pleasant city with a wide cultural and gastronomical offer.


Journal of Sea Research has accepted to host a special issue with papers (oral/poster) presented at ISOBAY 15 following full paper submission and peer review. Paper submission deadline is 15 October 2016. Fernando Villate, Pierre Anschutz, Ángel Borja and Moncho Gómez Gesteira will be Guest Editors.


The symposium venue will be the Bizkaia Aretoa of the University of the Basque Country (UPV/EHU), located in the city centre, within walking distance from the Guggenheim museum of modern art. Oral presentations will be in the Mitxelena auditorium and posters will be shown in the Etxepare and Axular exhibition galleries.
