Sediment-coring is an important technique in geomarine science to validate hydroacoustic data and to interpret the sedimentological built up of seafloor deposits. While coring in soft sediment is simply done by gravity coring, sandy deposits can only be penetrated by vibro- coring. As most of the shallow waters in coastal areas are built up by sandy deposits, this technique is necessary to acquire material from these environments.

Technical data /Features

  • Height: 7.50 m
  • Diameter of frame: 4.60 m
  • Length of core: 6.00 m
  • Weight: 1000kg
  • Diameter of liner: 96 mm
  • Operating voltage: 380 – 440 V
  • Frequency: 50 Hz
  • Rated power: 4 kV
  • Frequency of vibrator: 28 Hz
  • Max. Operating depth: 250 m

For the use on smaller research vessels the whole system can be adjusted to 3 m core-length (height: 4.7 m, diameter of the frame: 2.9 m, see figure). For the operation a qualified technician is highly recommended.

Application

Sediment coring in sandy, consolidated sediments in coastal and shelf areas.
