NCK days 2020 canceled

On Thursday, 12 March 2020, we informed the participants of the cancellation of the NCK days 2020 on Texel, which were scheduled to take place on 18-20 March. The organizers from NIOZ and the chair of the NCK CvT (the supervisory board) have jointly monitored the situation regarding the coronavirus (COVID-19) during the last few weeks. We follow the directives of the National Institute for Public Health and the Environment (RIVM), that impose cancellation of all activities with more than 100 attendees.

The conference fee will be refunded. Please do not forget to cancel the hotel, if you booked one.



General information

You are all invited to join the NCKdays 2020! They will take place on March 19 and 20 at NIOZ Royal Netherlands Institute for Sea Research on the island of Texel. This year, we kick off the NCK days with an excursion to the Prins Hendrik Zanddijk on Wednesday afternoon, March 18 (more info below). After the excursion you may join the hands-on sprint session on the field data collected during the SEAWAD project (more info below). The icebreaker will also be on Wednesday, from 20:00-22:00 hours in Hotel-Restaurant De Lindeboom, Den Burg. The program on Thursday and Friday will be filled with interesting key notes, oral and poster sessions, and of course ample time to catch up with your colleagues. When you register you can indicate which parts of the program you will join. More details on the program can be found further below.


Registration and fee

It is not possible to register anymore. You registration is finalised after you have paid the fee. Your will receive a printed invoice at the NCK Days. This year, conference fees are:

  • Full conference: € 125
  • Thursday: €60
  • Thursday + conference dinner: € 95
  • Conference dinner + Friday: € 65
  • Friday: € 30
  • The excursion, sprint session and icebreaker are free of charge (but require registration). 



NIOZ is located directly next to the ferry on the island of Texel (view in Google Maps). It takes only a 5-minute walk to reach the main entrance.

The TESO ferry leaves Den Helder on an hourly service at every 30 minutes past the hour (XX:30 h.). The crossing from to Texel takes only 20 minutes. Detailed information about the tickets and time-tables can be found on the TESO website.


Overnight stay

If you want to stay overnight, you are kindly asked to make your own arrangements. One of our recommended hotels, De Lindeboom, is already fully booked. We also recommend the following hotel:

  • Hotel De Pelikaan, De Koog | 0222-317202 | This email address is being protected from spambots. You need JavaScript enabled to view it.
    Standard room € 69,50* p.r.p.n (2 nights)

* The price is based on single use, breakfast is included, local taxes are excluded.

Note 1: We took an option on a limited amount of rooms in this hotel which expired February 14.
Note 2: The room can be booked via email or phone, please mention “NCKdays NIOZ”.


Bus transport

We arrange bus transport after the Icebreaker to Hotel De Pelikaan and De Koog on Wednesday evening; the route De Koog-Hotel De Pelikaan-Den Burg-NIOZ on Thursday and Friday morning, and conversely on Thursday evening after the conference dinner. Please indicate during registration whether you want to use this special bus service.
NB: if you book a hotel that is not located along this route, then please arrange your own transport!


Book of Abstracts

To reduce our carbon footprint, we will no longer be handing out hardcopies of the Book of Abstracts during the NCK Days. The full Book of Abstracts is available as PDF and HTML. The advantages of the HTML are that the abstracts will scale on laptop, tablet and phone and abstracts are better found via search machines such as Google.

Excursion to Prins Hendrik Zanddijk (Wednesday)

The Prins Hendrikdijk at the southeast coast of Texel has recently been reinforced in an innovative way and turned into the Prins Hendrik Zanddijk, involving a seaward sandy extension with dunes and marshes. This has brought the dike in agreement with present safety standards, while creating new habitats. Mr Joël Verstoep (HHNK) will be the guide during this excursion.
The excursion will start and end at NIOZ, and will involve two half-hour walks.


Sprint session Kustgenese/SEAWAD

sprintsessieAfter the excursion you may join the hands-on sprint session on the field data collected during the Kustgenese/SEAWAD project. This project is a collaboration of Rijkswaterstaat, Deltares, TU Delft, University of Twente and Utrecht University. In 2017, these institutes organized a large-scale field campaign on the Ameland ebb-tidal delta in the North of the Netherlands, during which we measured waves, currents, benthos, bed composition and many other things across the entire delta. In October 2019, the entire data set became publicly available, so everyone can now freely use it. In this sprint session, we will give a more detailed overview of what we measured and how the data can be downloaded and analyzed. We will do this with some practical tutorials, so if you want to join, please bring your own laptop with either Matlab or Python running on it.



This edition of the NCK days is organized by Theo Gerkema and Nina Aalberts from Royal Netherlands Institute for Sea Research (NIOZ).
