The Swiss Polar Day 2018, held on 4 April, has gathered the Swiss scientific community working in Polar regions at the ETHZ in Zurich. More than 150 students, young scientists and experienced researchers have joined the event to meet colleagues, debate on future scientific priorities and listen to international keynote speakers active in the Arctic, Antarctic and high-altitude regions. The great attendance and participation really made the success of the event. The SPI team would therefore like to thank all the participants to the event – we hope to see you again at next year’s edition! The date will be announced in due course.
