EJKELKAMP - Van Veen Grab

Operational overview and field deployment

Instrument role in seabed sampling systems

Eijkelkamp Van Veen Grab is designed for collecting sediment samples from the seabed in aquatic environments. It is widely used in marine and freshwater sediment sampling campaigns where physical samples are required for laboratory analysis.

Functional usage context

This grab sampler is used to retrieve undisturbed or minimally disturbed sediment samples from the seabed surface. It is commonly applied in sedimentology, environmental monitoring, and benthic habitat studies to analyze grain size, contamination levels, and biological content.

Operational environment

The system is designed for deployment in rivers, lakes, estuaries, and offshore marine environments. It is suitable for use in soft to moderately compacted seabed conditions where reliable sediment penetration and closure are achievable.

System integration role

Within a sampling workflow, it functions as a mechanically deployed seabed collection tool. It is typically operated using a winch or crane system from a vessel and is often used alongside acoustic positioning or hydrographic instruments for site characterization.

Deployment usage

Deployment involves lowering the grab sampler to the seabed where it penetrates the sediment upon contact. The jaws close automatically upon retrieval, capturing a defined volume of seabed material for analysis.

Typical users

It is commonly used by environmental consultants, marine geologists, oceanographic institutes, and regulatory agencies conducting sediment quality assessments, benthic surveys, and environmental impact studies.
