Audun Rikardsen, Norway
Audun grew up in northern Norway, and has always been fascinated by the Arctic coast. He is a professor of fish biology at the University of Tromsø, and most of his images are taken locally or on field work. He has won several awards, including Arctic Photographer of the Year in 2014 and the WPY Portfolio Award in 2015. Audun hopes his images will help inspire nature conservation.
