Benthic Sediment Grabs
Mooring Systems, Inc. manufactures Benthic Sediment Grabs for collection of sediment samples.
Our Benthic Sediment Grabs (BSG) are constructed of type-316 stainless steel and model a clamshell design.
The grab is manufactured with a protective instrument frame for mounting of ballast and instruments.
The Benthic Sediment Grab is offered in a dual bucket configuration (BSG-2X) for collection of two samples in a single location.
Custom safety locking latches that are gravity-activated only when contact is made with the sediment interface. This design reduces pre-mature triggering of the grab bucket at the air-water interface.
Safety locking pin with tether for handling on deck.
500 μm stainless steel mesh with stopper flaps to reduce shock waves and loss of material. Serviceable latches for stopper flaps.
Built-in Over-Penetration Indicators for sample depth control.
Available with or without frame.
Configurable ballast in 20 lb. (9 kg.) increments for penetration of harder sediments.
Lightweight aluminum Stabilization Fin serves as an ideal platform for mounting commercially available cameras, lighting systems, and other instruments.
Soft sediment shoes to reduce disturbance of benthic environment.
Deployment Rope Assembly - includes user-defined length of 3/8” diameter Spectra/Dyneema 12-strand rope with spliced nylon thimble and connecting shackle.
