本文介绍了一种简单可靠的自动重力取芯器闭合机构，它与已发表的同类自动重力取芯器相比，具有三个主要优点。首先，它允许使用大直径管（内径至少为80 mm），减少了堆芯缩短效应。第二，它允许在下降过程中水的自由通过，最大限度地减少船头波浪的影响。第三，它足够紧凑，便于通过季节性冰盖使用。
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.
