Van Veen Grab Sampler
This sediment sampler has
a clam shell-type scoop setup. Although it tends to disturb the sediments
more than the hydraulically damped corer, it is much simpler to operate.
It can extract samples up to 20 centimeters deep within a sampling
area of 0.1 square meters.
Various types of clam-shell type benthic grab samplers, including the Van Veen grab, are available by loan from the Coastal Ocean Institute (COI) instrument pool and may be borrowed by contacting George Hampson (firstname.lastname@example.org).
