The Salish grab is a modified version of the standard Van Veen with a weighted frame and release system ideal for the collection of sediments in soft to hard substrates. The design of the Salish grab was optimized for the challenging conditions of the Salish seas where bottom substrates are often a combination of clays and rock mixed with silts and sands. The standard model is ideal for chemistry sampling with a penetration depth of up to 20 cm and ample volume for most sediment testing programs.
Bucket depth: 20 cm penetration
Material: 316 Stainless steel with lead blocks
Sampling area: 0.10 m2
Grab samplers are the industry-standard tool for the collection of surface sediment samples. Grab samplers are ideal for use on seafloors in hard or mixed substrates. The Van Veen Grab Sampler is a clamshell-style grab designed to sample sediment in water environments.
The sampler was invented by Johan van Veen (a Dutch engineer) in 1933. The use of Van Veen’s grab is very simple which has made it the industry standard for surface sediment sampling.
