A simple closure mechanism for a compact, large-diameter, gravity corer

  • J. F. Boyle
Note

Abstract

A simple and reliable corer closure mechanism is described, which has three principal advantages over published designs for similar automatic gravity corers. First, it allows the use of large diameter tubes (at least 80 mm internal diameter), reducing core shortening effects. Second, it allows free passage of water during descent minimising bow wave effects. Third, it is compact enough for convenient use through seasonal ice cover.
