The full report will be made available on hydrographicsocietybenelux.eu, as indeed will be most of the presentations. The se-ries of pitches was followed by a forum discussion, whereby the speakers were triggered to address subjects evolving from their views expressed ear-lier.The event was attended by 85 DHyG/HSB mem-bers (and three from THSUK) and 65 students from the first three years of the Ocean Technology train-ing program. Although the students didn’t partici-pate in the complimentary dinner on the Wednes-day evening, there was an easygoing and open interaction between visitors and students, aiding the start of a professional network for many of the students.The maritime stakeholders presenting their views were •	 Captain	RNLN	M.C.J.	(Marc)	van	der	Donck,	as Hydrographer of the navy leading the Hydrographic	Office	in	The	Hague;	•	 Mr	Thomas	Dehling,	head	of	the	Hydro-graphic Surveying Division at BSH, lecturer at HafenCity Universität Hamburg, chairman of the IHO working group on capacity building, and DHyG board member; •	 Dr.	Peter	Gimpel,	Director	of	Survey	Systems	at L-3 Elac Nautik; On 18th and 19th February an inspiring event took place between the two regional hydrographic so-cieties. It was the third in a row, after Delfzijl in De-cember 2011 and Papenburg in May 2013. During the Hydrographentag in Lübeck end of May 2014, the idea was born to invite members of the two neighbouring societies to a two-day event at the Maritime Institute Willem Barentsz on Terschelling. Gradually plans for the content developed. When in Lübeck Theresa Maierhofer presented her the-sis on measuring seabed ripple transport off the coast of Texel, she agreed to repeat her perform-ance in the Netherlands. From there the theme for the symposium was easily found: The dynamic Waddenzee. This would likely appeal to the hy-drography students who were also invited to the symposium held in their training institute.Guest speakers were found to present a most interesting variation of specialised views on the theme. This was on the second day. On the first day the program was built around seven maritime stakeholders from various applications and dis-ciplines who were invited to give their educated guess for the development of hydrography in the next five to ten years. Each was allowed a pitch of ten	minutes	–	a	truly	difficult	task.

For many students it was the first time to experi-ence a direct contact with the industry, they had the opportunity to speak to the representatives of companies and organisations that form their refer-ence for apprenticeships, thesis assignments and innovative developments.On the second day seven presentations shed their light on the various hydrographic aspects related to the Wadden Sea. The underlying rea-son for the choice of this theme is the school’s research program which addresses the preven-tion and damage control of oil spills threatening the sensitive Wadden Sea. From year to year 4th year students co-operate to answer many ques-tions about hydrographic aspects of this problem. The guest speakers addressed changing seabed geomorphology at various scales (Ernst Lofvers); bathymetric surveying using multibeam echo sounder (Theresa Maierhofer) and LiDAR (airborne laser) (Ramona Baran); measuring current profiles with ADCP as well as surface currents over larger areas with radar mounted on light houses by Sicco Kamminga. Herman Peters gave an overview of governmental measurement campaigns in the Dutch Wadden Sea. And finally current model-ling was addressed, both for open sea by Christian Maushake, and for areas with drying out tidal flats by Firmijn Zijl, including the aspect of validating such models with actual current measurements in order to put a quality figure to the predicted cur-rent values. In time for all delegates to find their way home on the same day, the program ended by 4th year hydrography student Johan Zegers, who showed recent results of visualising the trajectory of an oil spill of a selectable quantity and viscosity, originat-ing anywhere in the area, when moving by tide and wind. Apart from its usual objective to bring many colleagues together while focussing on some hydrographic theme, the symposium thus provided a very useful introduction to measuring in the marine environment for undergraduate stu-dents of the hydrographic training course at the Maritime Institute Willem Barentsz. “
