Hello and thank you for accepting me. My name is Joseph and I live near Barcelona. I'm no professional historian. I practice diving. hat is why I am specialized in underwater research. During the last 10 years I have been researching the traces of the First World War in the waters of southern Catalonia. I published a book in 2005 about it. http://www.amazon.es/guerra-secreta-del-Mediterrani-Submarins/dp/8497793293 We also made several documentaries. I leave several links: http://www.rtve.es/alacarta/videos/al-filo-de-lo-imposible/filo-imposible-20110410-2100-43/1070093/ http://www.rtve.es/alacarta/videos/al-filo-de-lo-imposible/filo-imposible-caminos-del-mar/1063588/ I am currently researching a similar project but focused on incidents of World War II in the same area. I hope to share information that I will find in my research. Greetings to all and thank you for administrators of the site.
