The NCK days will take place online on 25 and 26 March 2021, in the afternoon from 12:45-16:20. We have created three parallel sessions with short presentations, followed by questions/discussion. We have two plenary talks about the Wadden Sea by Ana Colina Alonso and Sander Holthuijsen. On Thursday evening we will organise a social event. In between the sessions, there is opportunity to meet in the ‘online’ lobby and to chat with your NCK colleagues. The Book of Abstracts is also available: as pdf and as separate web pages.
