| The RV Zeeleeuw can be reached by phone : 0476/40 40 89 or fax : 0477/78 03 52 |
The schedule for the RV Zeeleeuw is available here.
Also available is an overview of the cruises and campaigns in tabular form.
All underway data collected by the monitoring system and information on the research activities performed onboard is available through the same links.
To request ship time please use this form.
Scientists should be aware that campaigns in foreign waters necessitate diplomatic clearance through the Ministry of Foreign Affairs. Permission has to be requested from the administration concerned at least four months in advance. Therefore VLIZ draws up a tentative year programme to allow researchers and VLIZ to plan such campaigns.
