OSIL have completed the supply of another Mega Box Corer and ROV Niskin water sampling system to a West African survey company.
The Box Corers (also known as Spade Corers) are simple and reliable corers for sampling an area of sediment with minimal disturbance and sample contamination. Its unique double shovel design allows easy access to the sediment for sub-sampling for subsequent scientific investigation.
Available in a range of sizes, the corers are easily deployed from a deck stand and are lowered on a specific no-load release, which activates after sediment penetration. The box is closed top and bottom, by two closely fitting shovels, mounted on pivot arms. Removable weights allow the corers to be used successfully in a wide range of sediment types.
The Corers are widely used for sampling in biological, chemical and geochemical applications as the relatively large block of sediment provides a large well preserved sample.
OSIL have used 6 of the industry standard 5L Niskin bottle in the ROV fired water sampling system, which also incorporates sufficient space for an AML Oceanographic Plus X in the centre of the stainless steel frame. The Plus X is a dependable logger that uses field-swappable sensor-heads that makes it ideal for vertical profiling or multiparameter studies.
