Royal NIOZ (1)

• Founded in 1876 by the Netherlands Zoological
  Society Starting in a mobile wooden field station
  for sea-research

Royal NIOZ (3)

• Scientific Departments
• Physics , Chemistry, Biology and Geology
• Important Scientific fields of play
• Dark Ocean processes
• North-sea and Wadden Sea
• Past Ocean
• Benthic Boundary Layers
• Long-term Ocean-Climate Observations
• Staff approximately 250 total

Research Ships (1)

• Pelagia
• Area Atlantic Indian Ocean, Mediterranean
• Length 66 m, Crew 10, Scientists max 15

8
Research Ships (2)

• Navicula
• Length 24 m, Area North-sea, Wadden-sea

Marine Technology

• Three departments
• Mechanical
• Instrumentation
• Electronics
• 20 to 25 Employees

11
Main activities

• Technical support during cruises, in general 3
  technicians (2 Mech 1 Electr.)
• World-wide logistic support supervision,
  preparation and transport of lab-containers and
  equipment during port calls of RV Pelagia and
  other NIOZ-cruises
• Development and maintenance of marine research
  instruments and equipment.
• This means mechanical and electronical
  engineering, construction, instrumentation,
  procurement and testing.

Seismic Deep-sea Sparker array

• Less penetration, higher resolution
• Tested up to 4.500 m.
• Dimension 1.74 x 2.50 m.
• Electrical power 8 kV / 20 kA
• Development of Geo Resources Ltd

31
Boxcore with video-assembly

• On-line monitoring for finding the right
  sample-locations (as mud volcanoes)

32
Organizational issues

• Integration of Mechanical, Electronics and
  Instrumentation departments
• Working together (technicians and scientists!)
  on professional Project Management
• Development and implementation of Job Information
  System
• Openness and open communication
• Reducing the holiday and compensation hours
  reservoir
• Effective technology for excellent research
