The scientific and educational expedition “Kurils autumn” arranged from September 1 till September 20, 2017 has been successfully completed. The participants of the expedition sailed around the Paramushir Island (Northern Kuril Islands) on the catamaran ship. Marine mammals of the island were counted. Plenty of marine and terrestrial animals and birds made our route more exciting and interesting every day! Neither sudden debris flow over Severo-Kurilsk (for the first time in a post-war history), nor heavy ash explosions from Ebeko volcano, nor powerful typhoons could stop the expedition. I would like to express my sincere gratitude to all Severo-Kurilsk citizens for hearty and warm welcome!
