What are Characteristics of good core samplers?


Courtesy of Wildlife Supply Company (WILDCO)

  • Perpendicular placement: The core sampler must make a vertical or straight entry into sediments to secure a reliably representative cross-section sample.
  • Penetration: It must penetrate the sediments you expect to find and adaptable for many field situations.
  • Core retention: There should be minimal loss of any part of the sample during return to the surface.
  • Maximum sample validity: This means:
    • Samplers intended for layered sediments should obtain cores showing minimum disturbance of layers by compression or by displacement around the circumference.
    • Samplers intended to obtain bottom sediments and their resident fauna need a design which causes minimum displacement or escape of fauna during sampling.
  • Simplicity: Purchase the simplest instrument capable of producing the type of samples you require.
