Three coring systems
are manufactured that can retrieve an ice core through ice and firn
easily. The proprietary core barrel is a light weight filament wound
composite tube about 1.15 m long with plastic flighting. The cutting
shoe is aluminum and the cutting teeth are heat treated steel.
Stainless steel dogs, located in the shoe, help to capture the core at
the time of extraction from the ice. The drive head (patent pending) is
stainless steel and aluminum and allows for extremely fast coupling and
uncoupling from the core barrel. Two stainless steel 1 m long
extensions. Additional extensions can be purchased. A tee handle is
included for turning the core barrel by hand and an adapter is provided
for turning the system using a 1/2 inch (1.5 cm) electric drill
operating at 400 rpm or less These coring systems are a highly upgraded
version of the well known and regarded coring system used by
researchers at the Cold Regions Research and Engineering Laboratory.
These systems are furnished with a robust shipping case with lift
handle.
Our core barrel systems are fabricated upon receipt of
an order from our customer. Two (2) months plus shipping time for
delivery of the MARK II and III systems is required. The MARK V coring
system requires (3) months lead time for fabrication.
