Dr. Henk de Haas
Main interest and daily activities
Sea bed morphology and sedimentary processes in the marine environment (coast to deep sea) on short to long term time scales (tides to glacial-interglacial cycles and longer).
Advice and support (on shore and at sea) NIOZ and non-NIOZ scientists in the use of marine acoustic equipment. Help with acoustic data processing and interpretation. Assist in organising scientific cruises and the use of NIOZ owned equipment.
Member of the Avaatech XRF core scanner support team.
Current projects: EMODnet and AtlantOS.

Expedition Hotchpotch
During the last week the central theme in our work was sea level change, but this week has come to an end and it is time for a change of subject. And a change of people too. At 7 o’clock this morning Pelagia arrived at Texel. All the non-Pelagia crew…

North Sea Expedition 'Sea level rise'
About 12.000 years ago sea level was more 60m lower than today and large parts of the North Sea were dry land. In the following 4.000 years sea level rose more than 40m and the North Sea was formed. This story currently lies buried below the present…
