Jumbo piston corer Active

By Pacific Coastal and Marine Science Center June 23, 2020

Piston corers are generally used in areas with soft sediment, such as clay.

Engineering Technician Jenny McKee prepares the JPC for launching off research vessel R/V Bold Horizon off the coast of California and Oregon.

The Jumbo Piston Corer (JPC) is a coring system that combines a dynamically falling heavy gravity corer with an interior piston that works to expel water and draw sediment into the corer.  It is launched using a rail system, and can be configured in lengths from 10’ to 40’ (3m to 12m).  Piston corers, like gravity corers, are generally used in areas with soft sediment, such as clay. The addition of the internal piston allows the soft sediment to be captured without significant compression or disturbance.

 

Specifications

  • Manufacturer – Navy Engineering Lab (NEL) from WHOI design

  • Head Weight – 2,600 lbs (1,180 kgs)

  • Total System Weight (Including track system) - ~25,000 lbs.

  • Dimensions  - Assembled: 50’ x 8’ x 6’, Shipped: 1500 ft3

Operational Characteristics

  • Min Operational Depth - 50m

  • Max Operational Depth – limited only by amount of wire on ship

  • Sediment Type - Soft sediment, such as clay.

  • Limitations - Sand, rock, shell matrices.

  • Ship’s Requirements:

    • All overboarding gear rated to a SWL of 12 tons.

    • A-frame with minimum height of 15’ and at least two attachments for hanging blocks approximately 4’ apart.

    • 45’ of clear deck space forward from transom

    • Deck winch with line pull of at least 2,000 lbs for operating rail system

    • Deck winch with line pull of at least 1,000 lbs and drum capacity of at least 30m

    • Ability to hold station for duration of operation in variety of sea states.

 

Additional Equipment Required

  • Polybuterate liner, 3.43” ID liner

  • Refrigerated core storage, if needed

 

Complementary Systems

A box corer or gravity corer is often used prior to the JPC in sites of uncertain composition, to determine suitability for piston coring. They may also be used in conjunction with the JPC to return an undisturbed sample, as the JPC tends to blow out the softer sediments at the surface by the force of the impact and the bow wake of the cutter nose. The trigger core may sometimes return an undisturbed sample of the surface that can be correlated with the main corer to obtain a complete record.

Earthquake Hazards in Southeastern Alaska

Over the last 100 years, the Queen Charlotte-Fairweather fault system has produced large-magnitude earthquakes affecting both Canada and the U.S. To fill in missing details about its offshore location and structure, USGS uses sophisticated techniques to truly understand the fault’s hazard potential.
