| Definition | A messenger-triggered gravity corer comprising a release mechanism developed by J.R. Glew in 1991. Applications revolve around the sampling of aquatic sediments for property analysis. The size of the corer also allows it to pass through a 10cm hole, typical of the size cut by a hand ice auger, enabling the sampling of sediments under ice. The miniature corer operates on a single hand line and is closed by a messenger. The release mechanism is similar to that described by Glew (1988) but has fewer moving parts; the release mechanism consists of a single latch that is held open until triggered by the messenger. The overall dimensions of the corer are 33 cm long (without core tube) and 6 cm in diameter. The device is composed of a cylindrical aluminium alloy body with a nominal diameter of 50 mm. The lower part carries the sleeve and clamping device to secure the core tube; the upper part houses the closing piston, release mechanism, and captive float. The float relays the motion of the messenger to the trigger and gives the corer vertical stability in the water. The core tube has an inside diameter of 40 mm.
