OSIL Develops Accelerometer to Assist Piston Coring

Deep sea sediment corer manufacturers Ocean Scientific International Ltd (OSIL) have released a convenient accessory for their Giant Piston Corer, an accelerometer, which should aid operators with deployments.

The accelerometer can calculate the attitude of the corer head on penetration of the corer into the seabed, and the penetration rate of the barrel string, which will assist operators with multiple deployments in the same location. The accelerometer is housed in anodised aluminium canister that is rated to full ocean depth.

The Giant Piston Corer from OSIL can achieve up to 60m core samples in soft cohesive sediments and muds. The system is a modular construction with an integral piston, which, according to OSIL, reduces internal friction and prevents plugging.
